You can use egg white instead of aquafaba at a ratio of 3 tablespoons of aquafaba per egg white — which is to say, one egg white replaces 3 tablespoons of aquafaba, and the swap runs in either direction at the same ratio. This is the reverse of the more common aquafaba-for-egg swap: it is the substitution you make when a vegan recipe calls for aquafaba and you are not vegan, or when you want the reliability of a real egg white in a meringue, a mousse or a macaron. An egg white whips faster, whips stiffer, and holds its peaks longer than aquafaba, so the swap is an upgrade in performance — and this page explains when that upgrade matters and when it does not.

Egg white instead of aquafaba is the swap for bakers who tried the vegan version and want the original back. A meringue made with egg whites is crisper, drier and more stable than one made with aquafaba, because egg-white proteins form a stronger foam. A macaron made with egg whites has a smoother shell and a better foot. A chocolate mousse made with egg whites is lighter and airier. The trade-off is that the recipe is no longer vegan, and the egg white brings a faint eggy flavour that aquafaba does not have — though in a meringue or a mousse, that flavour disappears behind the sugar and the chocolate.

The ratio, in a table

The table below converts aquafaba to egg whites for the amounts you are most likely to meet. The rule is always the same: 1 egg white replaces 3 tablespoons of aquafaba. For reference, one large egg white is about 2 tablespoons (30 ml) by volume — which means the swap is not volume-for-volume: 3 tablespoons of aquafaba is replaced by 2 tablespoons of egg white, because the egg white is more concentrated in protein.

Aquafaba called for Egg whites to use Volume Notes
3 tablespoons 1 white 2 tablespoons Whips to peaks
6 tablespoons 2 whites 4 tablespoons (1/4 cup)
9 tablespoons 3 whites 6 tablespoons
12 tablespoons (3/4 cup) 4 whites 8 tablespoons (1/2 cup)
15 tablespoons 5 whites 10 tablespoons At the limit
18 tablespoons 6 whites 12 tablespoons (3/4 cup) Not recommended

One large egg white weighs about 33 grams, and 3 tablespoons of aquafaba weighs about 45 grams — the aquafaba is heavier, because it is mostly water, while the egg white is more concentrated in protein. If you are weighing ingredients, that is the number to use. Note that you are replacing a larger volume of liquid with a smaller volume of more concentrated protein, so the batter or foam will be slightly drier and more stable — which is an advantage in a meringue and a minor change in a mousse.

Worked examples

Example 1: A meringue that holds its peaks

A vegan meringue recipe calls for 9 tablespoons of aquafaba, whipped with sugar. Replace it with 3 egg whites. Whip the whites with a pinch of cream of tartar until soft peaks form, then add the sugar gradually and whip to stiff, glossy peaks — exactly as you would with aquafaba, but the peaks will form faster and hold longer. Pipe or spoon the meringue onto a lined tray and bake low and slow, at about 100°C for 90 minutes. The meringues will be crisper and drier than the aquafaba version, with a cleaner flavour, and they will keep longer in an airtight container.

Example 2: A chocolate mousse with a lighter texture

A vegan chocolate mousse recipe calls for 6 tablespoons of aquafaba, whipped and folded into melted chocolate. Replace it with 2 egg whites, whipped to stiff peaks with a pinch of cream of tartar. Fold the whites into the cooled chocolate gently, so you do not knock out the air, and chill the mousse for at least four hours. The result is a lighter, airier mousse than the aquafaba version, with a cleaner chocolate flavour. This is the recipe where the swap is most obviously an upgrade: the egg whites' stronger foam makes a better mousse.

Example 3: Macarons with a better foot

A vegan macaron recipe calls for 9 tablespoons of aquafaba. Replace it with 3 egg whites, aged overnight in the fridge if you can — aged whites whip better and give a smoother macaron shell. Whip the whites with the sugar, fold in the almond flour, pipe the shells, rest them until a skin forms, and bake as usual. The macarons will have a smoother shell, a better foot, and a chewier interior than the aquafaba version. This is the recipe where the egg white's superiority is most pronounced: aquafaba macarons work, but egg-white macarons work better.

What changes in the result

Three things change when you swap egg whites for aquafaba. First, the stability: egg-white foam is stronger and more stable than aquafaba foam, so meringues, mousses and macarons made with egg whites hold their shape better and keep longer. Second, the texture: egg-white meringues are crisper and drier, while aquafaba meringues are slightly chewier and more prone to weeping in humidity. Third, the flavour: egg whites have a faint eggy taste that aquafaba does not have, though in a meringue or a mousse the sugar and flavourings cover it. The practical consequence is that the swap is an upgrade in performance and a downgrade in vegan credentials — use it when the recipe's success matters more than its vegan status.

The other change is practical: egg whites are easier to work with. Aquafaba's whipping power varies with the brand of chickpeas and the thickness of the liquid, so a vegan meringue can be unpredictable. Egg whites are consistent: they whip the same way every time, provided no yolk gets into them. If you have ever had an aquafaba meringue fail, the egg white is the fix.

When not to substitute

Do not use egg whites instead of aquafaba if the recipe must stay vegan — that is the whole point of the aquafaba, and the swap removes it. Do not use it if anyone eating the food has an egg allergy: aquafaba is egg-free, and the swap reintroduces the allergen. Do not use it in a recipe where the aquafaba's liquid volume matters — a cake batter, for example, where the aquafaba contributes moisture as well as binding — because the egg white is a smaller volume and the batter will be drier. And do not use it in a recipe that calls for more than five egg whites' worth of aquafaba — beyond that, the recipe relies too heavily on the foam, and the swap's volume difference becomes significant. The swap is for whipped recipes — meringues, mousses, macarons — where the foam is the point.

One more caution: make sure no yolk gets into the whites. Even a trace of fat will stop egg whites whipping properly, and the meringue will fail. Separate the eggs carefully, use a clean, dry bowl, and do not use a plastic bowl that has held fat — glass or metal is better.

Frequently asked questions

How many egg whites do I use instead of 3 tablespoons of aquafaba?

Use 1 egg white for 3 tablespoons of aquafaba. That is the standard ratio, and it runs in both directions: 3 tablespoons of aquafaba replaces 1 egg white, and 1 egg white replaces 3 tablespoons of aquafaba. One egg white is about 2 tablespoons by volume, so the swap is not volume-for-volume — the egg white is more concentrated in protein.

Can I use egg whites instead of aquafaba in a meringue?

Yes — and the meringue will be better. Egg whites whip faster, whip stiffer, and hold their peaks longer than aquafaba. Whip the whites with a pinch of cream of tartar, add the sugar gradually, and bake low and slow. The meringues will be crisper and drier than the aquafaba version, and they will keep longer.

Is an egg white better than aquafaba for macarons?

Yes. Egg-white macarons have a smoother shell, a better foot and a chewier interior than aquafaba macarons. Aquafaba macarons work, but they are more temperamental — the foam is weaker, the shells are more prone to cracking, and the foot is less pronounced. If you are not vegan, use egg whites for macarons.

Does an egg white taste different from aquafaba?

Slightly. Egg whites have a faint eggy taste that aquafaba does not have, though in a meringue or a mousse the sugar and flavourings cover it. Aquafaba has a very mild beany taste that egg whites do not have. In practice, neither is noticeable in a finished meringue or mousse — the flavour comes from the sugar, the vanilla and the chocolate.

Can I use carton egg whites instead of fresh?

Yes. Carton egg whites are pasteurised and work the same way as fresh whites in baking, though they may whip slightly less well. Use the same ratio — 1 white per 3 tablespoons of aquafaba, or 1/4 cup of carton whites per 3 tablespoons. Carton whites are convenient when you need a large quantity, and they are a good way to use up a carton that is about to expire.

How do I separate egg whites from yolks?

Crack the egg into your hand over a bowl and let the white slip through your fingers, or crack it into a small bowl and lift the yolk out with a spoon. The cleanest method is to crack the egg over a bowl and pass the yolk back and forth between the shell halves, letting the white fall. Make sure no yolk gets into the whites — even a trace of fat will stop them whipping properly.
