How to Whip Egg Whites
Get every trace of fat out of the way and the rest is easy. A spotlessly clean, dry bowl and a clean separation matter more than your mixer, your speed, or your technique.
A speck of yolk is enough to stop the whole bowl from whipping. So is an oily film left on plastic, or a beater that was wiped with a greasy dish towel. Fat molecules crowd out the egg proteins at the surface of each bubble and the foam collapses as fast as you build it.
Once the bowl is clean, the sequence is short: start slow to break the whites up, raise the speed, add a pinch of cream of tartar, and stop at the stage your recipe asks for.

How to whip egg whites, step by step
- Wipe the bowl and beaters with vinegar or lemon juice on a paper towel, then dry them. This takes ten seconds and removes invisible fat films.
- Separate the eggs cold, one at a time, into a small third bowl. Transfer each clean white into the mixing bowl only after you've confirmed it's yolk-free. One bad separation then costs you one white, not five.
- Let the whites sit out for 20 to 30 minutes to come toward room temperature.
- Start on low speed until the whites are loose, foamy and uniformly bubbly, about 30 seconds.
- Add your stabilizer, 1/8 teaspoon cream of tartar per white, at the foamy stage.
- Raise to medium-high. Not maximum. Medium-high builds smaller, more uniform bubbles that hold up longer.
- If you're adding sugar, start at soft peaks, a tablespoon at a time with the mixer running.
- Stop at the stage your recipe names and check by lifting the whisk, not by looking at the bowl.
The two steps people skip are 1 and 2, and they're the two that decide whether this works.
Why fat stops egg whites from whipping
An egg-white foam is a wall of unwound protein molecules holding air bubbles apart. When you whip, the mechanical action denatures those proteins, meaning it unfolds them from tight balls into long strands. The strands link up at the air-water boundary and form a flexible skin around every bubble.
Fat molecules go straight to that same boundary, because that's where they're most comfortable, and they get there faster than proteins do. Once a fat molecule sits in the wall, the protein network has a hole in it and the bubble pops.
That's why the amounts are so small. A single drop of yolk in a bowl of six whites can cut your final volume in half or prevent any foam at all, and yolk is roughly a third fat by weight.
Places fat sneaks in: - A broken yolk during separation - Plastic bowls, which hold oil in surface scratches - Beaters stored next to buttery equipment - A dish towel used to dry the bowl - Hands, if you separate eggs with your fingers after handling butter
How yolk gets in, and how to get it out
Yolk almost always arrives one of three ways. Cracking the egg on the rim of the bowl drives shell fragments down into the yolk. Passing the yolk back and forth between shell halves cuts it on a sharp edge. And separating directly over the bowl you're whipping into means one bad egg ruins every good one already sitting there.
The habit that solves all three is the same one in step 2 above: separate each egg over a small third bowl, look at the white, then pour it across. Our guide on how to separate eggs covers the three methods and which is fastest with cold eggs.
If a fleck of yolk does land in a white, scoop it out with a piece of the eggshell rather than a spoon. The shell edge cuts cleanly through the white and the yolk clings to it, while a spoon just chases it around the bowl. If the yolk has already broken up and dispersed, that white is finished. Use it for scrambled eggs and crack another.
Bowl material: what works and what doesn't
| Bowl | Works? | Notes |
|---|---|---|
| Copper | Yes, best | Copper ions bond with conalbumin in the white, making the foam more stable and much harder to over-whip. Expensive and needs scrubbing with salt and vinegar. |
| Stainless steel | Yes | The practical everyday choice. Non-porous, easy to degrease, and it's what most stand mixer bowls are. |
| Glass | Yes | Non-porous and easy to check for smears. Slippery sides mean whites climb a little slower, so give it an extra minute. |
| Ceramic / glazed | Yes | Fine if the glaze is intact and unscratched. |
| Plastic | No | Plastic is porous and slightly oil-loving. It holds a fat film that survives dishwashing, and you cannot see it. Don't use plastic bowls for egg whites. |
| Silicone | No | The same problem as plastic, and worse. Flexible sides also give the whisk nothing to work against. |
Say it plainly: plastic doesn't work reliably, and when it fails you'll blame your technique instead of the bowl. Use metal or glass.
Two quieter sources of fat in an otherwise clean kitchen: a dish towel that dried a buttered pan earlier in the week, and a stand mixer whisk with a trace of buttercream left up in the wire joints. Run the whisk under hot water and look at the point where the wires meet the hub.
If a copper bowl isn't in your kitchen, cream of tartar does much the same stabilizing job and costs almost nothing.
The three stages, and what each one looks like
Stop the mixer, lift the whisk straight up out of the foam, and look at the peak that forms on the whisk. That's the only reliable check. The surface of the bowl looks the same across all three stages.
| Stage | What the peak does | Texture | Use it for |
|---|---|---|---|
| Soft peaks | Peak forms, then folds over completely on itself | Loose, wet, still flows if you tilt the bowl | Folding into mousse, souffle base, adding sugar |
| Firm peaks | Peak stands, tip curls over about halfway | Glossy, holds shape, doesn't flow | Folding into cake batter, most meringue toppings |
| Stiff peaks | Peak stands straight up with only a slight hook at the tip | Dense, very glossy, cuts clean | Piped meringue, angel food, macarons, baked shells |
| Over-whipped | Peak breaks off or won't form | Grainy, dull, cottage-cheese lumps with watery liquid pooling underneath | Nothing. See the rescue below. |
The old test of turning the bowl upside down works for stiff peaks, and it's a fine confidence check the first few times. It's also a bad habit, because it's a pass-fail test with an expensive failure.
What over-whipped egg whites look like
Over-whipping doesn't look like more of a good thing. It looks like a different substance.
The whites go from smooth and glossy to matte and grainy. Small curdled clumps appear, the mass separates into lumps and a thin liquid that pools at the bottom of the bowl, and the whole thing loses its ability to hold a shape.
What happened: you kept unwinding proteins past the point of usefulness. The strands cross-linked with each other rather than staying spread around bubbles, squeezing water out of the network. It's the same mechanism as over-whipping cream into butter, only faster and less delicious.
People often report this as "they won't whip," because the bowl looks wrong, when it's the opposite problem. The tell is simple: over-whipped whites looked good five minutes ago and look worse now. Under-whipped whites never looked good at any point.
The partial rescue: add one fresh, unwhipped white to the bowl and whip on medium for about 30 seconds. The fresh proteins are still folded and they redistribute through the broken network, bringing back some smoothness and shape.
Call it a partial rescue honestly. You'll get back to usable, glossy, roughly soft-to-firm peak territory. You will not get back the volume you had, and for a macaron or a piped meringue shell where structure is everything, start over.
Cold or room temperature? Do both, in order
Both pieces of advice you've heard are correct, and they apply at different moments.
Separate cold. A cold yolk membrane is firm and holds together when you move it between shell halves or your fingers. A room-temperature yolk is slack and breaks easily, and a broken yolk in the bowl means starting that white again.
Whip warm. Whites at 65 to 70°F are less viscous, so the proteins unwind faster and the foam builds with less effort. Room-temperature whites reach roughly 20 to 25% more volume than fridge-cold whites and get there in noticeably less time.
So the practical sequence is: separate straight from the fridge, then let the whites sit on the counter for 20 to 30 minutes before you whip.
In a hurry, set the bowl of separated whites inside a larger bowl of warm tap water for five minutes and stir gently. Don't microwave them, and don't let them get above about 75°F, since warm whites are also more fragile once whipped.
Age matters less than people think, but it does matter. Fresh whites are thick and tight, so they take a little longer to loosen and they build a stronger, more stable foam. Older whites are thinner, whip up faster and reach more volume, and that volume drains away sooner. Eggs anywhere from a few days to a couple of weeks old are the comfortable middle, which is essentially any carton from a store. Very fresh eggs straight from a farm want an extra minute or two at the start, and very old whites are the risky end, because they can look impressive in the bowl and then weep the moment you fold them.
Separated whites keep in the refrigerator for up to four days in a sealed container and whip perfectly well. Bring them to room temperature first, and give a pooled batch longer to warm than you would give individual whites.
Stabilizers: cream of tartar, acid and sugar
A plain egg-white foam is unstable. It starts leaking water within minutes. Stabilizers slow that down.
| Stabilizer | Amount | When to add | What it does |
|---|---|---|---|
| Cream of tartar | 1/8 tsp per white | At the foamy stage, before speed goes up | Lowers pH, which helps proteins unfold evenly and resist over-coagulating. Widens the window between stiff and over-whipped. |
| Lemon juice or white vinegar | 1/4 tsp per white | At the foamy stage | Same acid effect, slightly less effective by weight, adds a trace of liquid |
| Granulated sugar | 2 tbsp (25 g) per white for meringue | Starting at soft peaks, gradually | Dissolves into the water phase, thickens it, and physically slows drainage out of the foam |
| Copper bowl | n/a | n/a | Chemically equivalent to cream of tartar, no additions needed |
Cream of tartar is the default and it's cheap. If you don't have it, lemon juice or plain white vinegar does the job, and neither leaves a detectable flavor at these amounts. Our explainer on what is cream of tartar covers why an acid helps at all, cream of tartar substitutes lists what to reach for when the jar is empty, and our substitutions guide has the full acid-swap ratios.
Salt does the opposite, which surprises people. It destabilizes the foam and slows the whip, so if a recipe calls for salt, add it with the dry ingredients rather than to the whites.
When to add sugar, and why timing costs volume
Sugar is a stabilizer and a saboteur at the same time.
Sugar molecules dissolve into the water between bubbles and make that liquid thick and syrupy. Thick liquid drains more slowly, so a sugared meringue stays up for hours instead of minutes. That's the benefit.
The cost is that the same thick liquid makes it much harder for proteins to move to the bubble walls and link up. Sugar added to unwhipped whites slows foam formation dramatically and caps your final volume, sometimes cutting it by a third.
Add sugar starting at soft peaks, one tablespoon at a time, with the mixer running on medium-high. By that point the protein network already exists and the sugar's job is to reinforce it, not to get in its way.
Take your time. Dumping it in at once weighs the foam down and leaves undissolved crystals, which is what causes the beads of syrup that weep out of a baked meringue.
How to tell it's dissolved: rub a little between your finger and thumb. If it feels gritty, keep whipping. If it feels smooth, you're done. This takes about 2 minutes of whipping after the last addition.
Superfine sugar dissolves faster than granulated. Standard granulated is 200 g per cup, so 2 tablespoons is 25 g, and a four-white French meringue at that ratio takes 100 g of sugar, which is exactly half a cup.
Worked example: a four-white meringue
You're making a meringue that calls for 4 large egg whites and 1/2 cup of sugar.
| Item | Count | Weight |
|---|---|---|
| Large egg, out of shell | 4 | about 200 g |
| White portion (roughly two-thirds) | 4 | about 132 g |
| Yolk portion | 4 | about 68 g |
| Granulated sugar, 1/2 cup | 100 g |
The sugar-to-white ratio here is 100 g to 132 g, or about 0.75 to 1. That's a soft, foldable French meringue.
The timeline, on a stand mixer:
- 0:00 Whites in the clean bowl at 68°F. Low speed.
- 0:30 Loose and uniformly foamy. Add 1/2 tsp cream of tartar (1/8 tsp per white). Raise to medium-high.
- 2:00 Soft peaks. The peak on the whisk flops over entirely.
- 2:00 to 4:00 Add the 100 g of sugar, one tablespoon at a time, roughly every 15 seconds.
- 5:30 Firm peaks, very glossy. Rub-test the sugar between your fingers.
- 6:00 Stiff peaks. Stop.
Total: about 6 minutes. A hand mixer takes 9 to 12 minutes, and a balloon whisk by hand takes 10 to 15 minutes of steady work and won't reach the same volume.
If you're stuck without eggs entirely, aquafaba whips into a similar foam. Egg substitutes in baking covers the ratios and where the swap does and doesn't hold up.
How to fold whipped whites without deflating them
Folding is the step where careful whipping gets thrown away. What you're protecting is a structure of thin protein walls holding bubbles apart, and stirring shears those walls apart.
The physical difference: stirring drags in a circle, folding lifts from the bottom and turns over the top. Circular motion tears the network. Vertical motion moves it as a mass.
The method:
- Sacrifice a quarter. Stir a quarter of the whites into the heavy base mixture and don't be gentle about it. This lightens the base so the remaining whites meet something closer to their own density. Losing that quarter saves the other three quarters.
- Add the rest on top, all at once. Adding it in small amounts means more folding strokes overall, which does more damage.
- Use a wide silicone spatula, not a spoon.
- Cut down through the center to the bottom of the bowl. Sweep along the base toward you, up the near side, and turn the spatula over so the base mixture flips onto the whites.
- Rotate the bowl a quarter turn and repeat.
- Stop while a few white streaks remain. They disappear in the oven. Chasing the last streak costs you more volume than the streak costs you.
Aim for 15 to 25 folds total. A well-folded batter drops off the spatula in a soft ribbon rather than pouring.
Get the batter into the pan immediately once folded. Every minute it sits, more liquid drains out of the foam.
One thing worth internalizing here: for anything that gets folded, a stable foam beats a tall one every time. Slightly over-whipped whites break into clumps as soon as you start folding and leave stubborn streaks that no amount of extra strokes will clear. Our guide on how to fold ingredients applies the same motion to whipped cream and to batters generally.
Troubleshooting: when the whites won't whip
Fat is the answer nine times out of ten, and you already know how to rule it out. The remaining causes each leave a different mark in the bowl, so stop the mixer, look at what is actually in front of you, and match it to a row.
| What you see | The cause | What to do |
|---|---|---|
| Big loose bubbles like dish soap, going nowhere after 5 minutes | Fat, almost certainly yolk or a greasy bowl | Start over with a degreased metal or glass bowl and fresh whites |
| Foams a little, then stops | Trace fat, or whites too cold | Wipe the bowl with vinegar, warm the whites to 65 to 70°F |
| A thin foam that thickens slightly and then stalls | Sugar went in before soft peaks | Keep beating and allow roughly twice the usual time |
| Foam building only in the whisk's track, liquid pooling below | Too few whites for the size of the bowl | Tilt the bowl, switch to a smaller one, or add another white |
| Soft peaks that will not go stiff no matter how long you run it | Trace fat, or whites that were very old | Add cream of tartar, accept soft peaks, or restart clean |
| Grainy and curdled with liquid underneath | Over-whipped, not under-whipped | Whip in one fresh white for 30 seconds, accept lower volume |
| Watery liquid pooling after 10 minutes | No stabilizer used | Add 1/8 tsp cream of tartar per white next time, at the foamy stage |
| Low volume even though it whipped | Sugar added too early, or whites straight from the fridge | Wait for soft peaks before adding sugar, let whites warm first |
| Beads of syrup on a baked meringue | Undissolved sugar | Add sugar more slowly, whip until the rub test is smooth |
| Meringue weeps under a pie topping | Underbaked base, or foam shrunk from cooling too fast | Spread the meringue onto a hot filling and seal it to the crust edge |
| Batter deflates after folding | Over-folding, or the base was too dense | Sacrifice a quarter of the whites first, stop at 20 folds |
| Stiff peaks, then collapsed on standing | Waited too long before baking | Fold and bake within a few minutes |
The first row deserves bluntness: if it still looks like dish soap after five minutes, it is not going to recover. Nothing you add rescues contaminated whites. Wash everything, degrease it, and start again separating one egg at a time over a small bowl.
The bowl can be too big
This one catches people with a new stand mixer. A 5 quart bowl is enormous, and two egg whites sit in it as a shallow puddle that the whisk skims across without ever pulling air down through the liquid. The tells are foam forming only in the track the whisk cuts, liquid pooling underneath it, and a bowl that looks half finished forever.
The fixes, in order of how well they work: use a hand mixer, which you can chase the whites around a small bowl with; switch to a 2 quart bowl, which handles two whites comfortably; tilt the stand mixer bowl so the whites pool where the whisk sits, if your machine allows it; or simply add another white. Three or four whites is the practical minimum for a full-size stand mixer bowl.
How long it should actually take
Most "they won't whip" verdicts are delivered a couple of minutes early. These are the honest numbers for four whites with no sugar.
| Tool | To soft peaks | To stiff peaks |
|---|---|---|
| Stand mixer, medium-high | 2 to 3 min | 4 to 5 min |
| Hand mixer, medium-high | 3 to 4 min | 5 to 7 min |
| Balloon whisk, by hand | 6 to 8 min | 12 to 15 min |
| Copper bowl and whisk | 5 to 7 min | 10 to 12 min |
Adding sugar roughly doubles all of it, because the crystals have to dissolve as well as the foam having to build. If you are past double the expected time with nothing happening, stop and check for fat rather than beating on.
Working it out: four whites that stalled
You put four whites in a stand mixer bowl, ran it on high for six minutes, and you have a bowl of loose bubbles. Here is the order to check.
- Look at the texture. Big soapy bubbles with liquid underneath means fat. Small, tight bubbles that simply aren't climbing means time or temperature.
- Check the bowl material. If it's plastic or silicone, that is your answer and you can stop here.
- Look for yolk. Tip the bowl toward a window and scan the liquid layer for a yellow thread. A pinhead is enough to do it.
- Check the volume against the bowl. Four large whites is about 132 g, which is roughly half a cup of liquid. In a 5 quart bowl that is a thin film.
- Do the volume math. Whipped properly, four whites climb to 3 to 4 cups of foam, a six to eightfold increase. If you are at a cup and a half after six minutes, something on the list above is wrong.
- Restart properly. Wipe a stainless bowl and the whisk with vinegar. Separate four fresh eggs one at a time over a small bowl. Let the whites sit 20 minutes, start on low until foamy, add 1/2 tsp of cream of tartar, then run at medium-high for 4 to 5 minutes.
Frequently asked questions
Why won't my egg whites whip?
Fat, almost every time. A speck of yolk, a plastic bowl, or an oily beater will stop a foam from forming no matter how long you run the mixer. Start over with a metal or glass bowl wiped with vinegar and a clean separation.
Can I whip egg whites in a plastic bowl?
No, and it's worth being firm about this. Plastic is porous and holds an oil film that survives washing, so it sabotages the foam invisibly. Use stainless steel, glass or copper.
What's the difference between soft, firm and stiff peaks?
Lift the whisk. A soft peak folds over completely, a firm peak curls about halfway, and a stiff peak stands straight up with a small hook at the tip. The bowl looks identical at all three stages, so the whisk test is the only reliable check.
Should egg whites be cold or room temperature?
Separate them cold, because a cold yolk holds together and won't break into the white. Then let the whites sit out 20 to 30 minutes before whipping, since warmer whites reach 20 to 25% more volume.
Can you fix overbeaten egg whites?
Partly. Add one fresh unwhipped white and whip on medium for about 30 seconds, and the foam will come back to a usable, glossy state at reduced volume. For macarons or piped shells, start over instead.
Do I need cream of tartar for egg whites?
Not strictly, but it widens the margin between stiff and ruined and it costs almost nothing. Use 1/8 teaspoon per white, or substitute 1/4 teaspoon of lemon juice or white vinegar per white.
When should I add sugar to egg whites?
At soft peaks, one tablespoon at a time with the mixer running. Sugar added at the start slows foam formation and can cut your final volume by a third, because it thickens the liquid the proteins need to move through.
How much does one egg white weigh?
About 33 g for a US large egg, with the yolk around 17 g, adding up to roughly 50 g out of the shell. Weighing whites is far more accurate than counting them when egg sizes vary.
Why do my whipped egg whites go watery after a few minutes?
That's drainage, and it means the foam was either over-whipped or never stabilized. Add cream of tartar at the foamy stage, 1/8 teaspoon per white, and make sure any sugar is fully dissolved by rubbing a little between your fingers. Then use the meringue right away instead of letting it stand.
Can I whip egg whites by hand without a mixer?
Yes, with a large balloon whisk and a wide bowl. Allow 12 to 15 minutes for four whites to reach stiff peaks, and keep the whisk moving in a wide lifting circle rather than a tight stir, since the aim is to drag air down into the liquid. A copper bowl cuts the effort noticeably and makes the foam much harder to ruin.
Are stalled egg whites why my macarons failed?
Often, yes. Macarons need a meringue at firm to stiff peaks, and a weak foam collapses during the folding stage, which gives you flat shells with no rise. Our guide on why do my macarons have no feet works through the other causes, including drying time and oven temperature.
Can I whip aquafaba the same way?
Mostly. Chickpea liquid builds a similar foam and follows the same rules about fat and stabilizers, but it takes longer and wants more cream of tartar. Our vegan egg white substitute guide has the ratios and the places the results genuinely differ from real whites.
