How to Store Extra Egg Whites
If you aren’t using your egg whites immediately, proper storage is key. Egg whites will keep for up to a week in an airtight container in the fridge, but freezing is even better for long-term use.
- Refrigeration: Store in a clean, tightly covered jar or bowl. Label with the date and number of whites.
- Freezing: Place each egg white in an ice cube tray for individual portions. Once frozen, transfer to a freezer bag and label. Thaw overnight in the fridge or place in a bowl of warm water for quick thawing.
- Measurement Tip: One large egg white ≈ 30 grams or 1/8 cup.
Frozen whites can be used in any cooked application or baking recipe that calls for egg whites only, though they aren’t ideal for uncooked recipes like cocktails unless the freshest flavor is critical.
Classic Dessert Ideas
Egg whites shine brightest in the world of desserts, lending structure, lightness, and an irresistibly tender crumb to baked goods. Here are some classic ways to transform your extras into showstopping sweets:
Meringue Marvels
The ultimate destination for egg whites, meringues are the feather-light, crisp-on-the-outside treats beloved by all ages. Whether you have one egg white or a full dozen, you can scale the basic recipe to fit:
- Simple Meringues: Combine egg whites with a pinch of salt and whisk until foamy, adding sugar gradually until glossy peaks form (use the ratio: 1 part egg white, 2 parts sugar). Bake low and slow for classic cookies, or use as a base for other desserts.
- Pavlova: Bake your meringue into a round, then top with whipped cream and fresh fruit for a flourish of color and flavor.
- Eton Mess: Toss broken pieces of meringue with whipped cream and berries for a quick, decadent dessert.
- Swiss or Italian Meringue: These styles cook the sugar with the egg whites for a silkier, more stable result—ideal for pie toppings or piping onto pastries.
Angel Food Cake
The ethereal crumb of angel food cake is possible only through whipped egg whites, which are gently folded into flour and sugar for a dessert so light it nearly floats. Use a dozen whites and serve with berries and whipped cream for a summer classic.
Chiffon and Sponge Cakes
These cakes use egg whites either in part or in whole, creating airy, light textures ideal for layering with fruit, cream, or custard.
- Pumpkin Chiffon Cake: Fold whipped whites into a spiced cake batter for a festive, fluffy treat.
- Genoise: Whipped whites are key to the structure of this cornerstone European sponge.
Macarons and Biscuits
The famously finicky French macarons use only egg whites to achieve their shiny, delicate domes. Italian amaretti biscuits are similar, starring whipped whites and ground nuts for a chewy, naturally gluten-free treat.
Marshmallows & Torched Toppings
Homemade marshmallows require just a trio of ingredients: whipped egg whites, sugar, and gelatin. Whip to soft peaks, then combine with syrup for the bounciest, freshest marshmallows you’ll ever taste. Egg whites also create beautiful, torched toppings for cakes and pies (think lemon meringue pie or s’mores cupcakes).
Beyond Dessert: Savory and Other Uses
Egg whites don’t just sweeten the deal in desserts; their binding strength and subtle flavor make them perfect for innovative savory applications as well.
Omelettes and Frittatas
- Egg White Omelettes: Whip up a protein-rich, low-fat meal. Pure whites are especially popular for breakfast with spinach, tomatoes, herbs, or a sprinkle of cheese. Whipped whites deliver a soufflé-like, fluffy finish.
- Frittata with Whites: Mix egg whites with leftover veggies for a quick and healthy lunch.
Soufflés and Savory Foams
Whipped whites provide structure to soufflés, both sweet and savory. Add to a base of cheese, spinach, or even smoked salmon and bake for an airy, melt-in-your-mouth result. Egg whites also form the airy base of many modernist foams in fine dining.
Binding & Coating
- Breading: Use whisked egg whites to help breadcrumbs or seeds adhere to chicken, fish, or tofu before baking or frying.
- Spring Rolls & Dumplings: Brush a little egg white on the edges of wrappers to help seal them firmly for steaming or frying.
Glazes for Baking
Brushed over breads, bagels, or buns before baking, egg whites give a professional, glossy finish—and help seeds or seasonings stick. For a softer, stickier finish, combine whites with a touch of water.
Clarifying Broth
Egg whites can clarify broths or consommés: whisk a few into simmering stock, and they’ll rise to the surface, carrying with them any impurities for a crystal-clear result.
Creative Baking Inspirations
The world of baking is full of recipes that call for extra egg whites or egg whites only. Here are more creative ideas to add to your repertoire:
- Financiers: Tiny French almond cakes that are rich and moist, made almost entirely with egg whites and browned butter.
- Nutty Meringue Layers: Fold ground nuts (like pistachios or hazelnuts) and citrus zest into whipped whites for sophisticated cakes or roulades, accompanied by vibrant sauces.
- Coconut Macaroons: Mix egg whites with shredded coconut, sugar, and just a pinch of salt, then bake for chewy coconut confections.
- Baked Alaska: Spread an airy egg white meringue over a dome of ice cream and cake, torch or bake until the meringue is golden and dramatic.
Tips for Meringue Success
- Use clean, grease-free bowls: Even a trace of fat will deflate your whites.
- Add a stabilizer: A small pinch of cream of tartar or a drop of vinegar improves stability and volume, especially for baked meringues.
- Gradually add sugar: For best volume, sprinkle in sugar a little at a time once the whites have started to foam.
- Bake low and slow: Meringues dry out rather than brown, so keep the temperature below 250°F (120°C) and bake until crisp.

Egg Whites in Cocktails
Egg whites are the secret to the silky, foamy head in a whole family of classic cocktails:
- Whiskey Sour: A single egg white adds luxurious texture and a smooth mouthfeel.
- Pisco Sour & Ramos Gin Fizz: Shake egg whites with liquor, citrus, and sugar, then strain and serve with a signature froth on top.
Quick Glossy Frostings

- Seven-Minute Frosting: Whisk egg whites and sugar over gentle heat, then beat into a cloud-like top for cakes and cupcakes.
How to Freeze and Thaw Egg Whites
- Portion Control: Freeze single whites in each compartment of an ice cube tray.
- Thawing: Allow whites to defrost in the fridge overnight or place in a sealed bag in a bowl of warm water for quicker thawing.
- Usage: Thawed whites are suitable for virtually all recipes, though super-fussy pâtisserie or cocktails might require the freshest whites for best results.
