8 Recipes to Use Up Leftover Egg Whites
Made a custard, carbonara, or lemon curd and now have a bowl of egg whites with nowhere to go? Eight real recipes — meringue, macarons, pavlova, an omelette — built specifically around egg whites.
Egg whites pile up fast in any kitchen that bakes with yolks regularly — a batch of custard, carbonara, crème brûlée, or lemon curd each leaves two to six whites behind with nothing planned for them. Unlike yolks, raw egg whites keep well: four to five days refrigerated in a sealed container, or up to a year frozen (they thaw and whip just fine, unlike frozen yolks, which turn gelatinous). The eight recipes below all use whipped or raw egg white as a structural ingredient — the thing that gives meringue its body, macarons their shell, or an omelette its lightness — not a minor addition you'd barely notice if you left it out.

Meringue Is the Highest-Volume Use
Lemon meringue pie, pavlova, and Eton mess all start from the same base technique: whipping egg whites with sugar until they hold stiff, glossy peaks, then either baking them into a crisp shell (pavlova, meringue for pies) or crushing pre-made meringue into a dessert (Eton mess). A single pavlova shell can use four or more whites in one go, which makes it the fastest way to work through a large stash. The technique differs slightly by dish — French meringue (whites and sugar whipped together raw, then baked) versus the hot-sugar-syrup Italian meringue used in suspiro a la limeña — but both start from the same whipped-white base.
Macarons and Amaretti Skip the Yolk Entirely
Unlike most baking, macaron shells and amaretti cookies use egg white as their only egg component — no yolk anywhere in the dough. That makes them genuinely useful if you're specifically trying to clear out whites without also needing yolks for something else, which is often the opposite problem from most 'leftover egg' situations. Both are more technique-sensitive than the meringue desserts above — macarons in particular are notorious for needing precise whipping and folding — so budget a practice batch if it's your first attempt.
Don't Forget the Savory Option
Every recipe above this point is a dessert, which isn't always what you want on a Tuesday. An egg white omelette — built from whipped or simply whisked whites, with the yolks left out entirely — is a fast, savory way to use a smaller number of whites without turning on the oven, whipping to stiff peaks, or weighing out sugar. It's the lowest-effort entry on this list by a wide margin.
How Long Leftover Whites Actually Last
Raw egg whites keep for four to five days in the fridge in a sealed, airtight container — noticeably longer than most leftover dairy or produce. They also freeze unusually well: whisk lightly, freeze in an ice cube tray or small container, and thaw in the fridge before whipping; frozen-and-thawed whites whip up almost identically to fresh. This is different from egg yolks, which don't freeze cleanly on their own. For the full storage-time breakdown across eggs, dairy, and other pantry staples, see our food storage guide.
Featured Recipes
Lemon Meringue Pie
The meringue topping is whipped egg whites and sugar — this recipe alone accounts for several whites on top of the yolks the filling already used.
View Recipe →French Macarons
Macaron shells are almost entirely egg white, almond flour, and sugar — no yolks at all, making this one of the purest egg-white uses on this list.
View Recipe →Pavlova
A large pavlova shell can take four or more egg whites whipped into stiff peaks — one of the highest-volume single uses here.
View Recipe →Amaretti
These Italian almond cookies are bound entirely by whipped egg white, with no flour or yolk in the dough at all.
View Recipe →Eton Mess
Built around crushed meringue, which means whipping and baking off egg whites is the first step before anything else happens.
View Recipe →Egg White Veggie Omelette
The one savory, non-baking option here — a straightforward way to use whites without turning on the oven or weighing sugar.
View Recipe →Suspiro a la Limeña
A caramel manjar blanco base topped with an Italian meringue made from whipped egg whites and hot sugar syrup — a genuinely different meringue technique than the others on this list.
View Recipe →Austrian Esterházy Torte
The cake layers themselves are a hazelnut meringue built on whipped egg whites, separate from the yolk-based buttercream between them.
View Recipe →Frequently Asked Questions
Why do egg whites keep so much longer than yolks?
Egg whites are almost entirely water and protein with very little fat, which makes them less hospitable to bacterial growth and less prone to the texture breakdown that affects yolks. Yolks are fattier and higher in nutrients, which is part of why they spoil faster and don't freeze as cleanly.
Can I whip egg whites straight from the freezer?
No — thaw them fully in the refrigerator first, ideally overnight, then bring to room temperature before whipping. Whites whip to greater volume at room temperature than cold, whether fresh or previously frozen.
Why did my meringue or macarons fail even though I followed the recipe?
The most common causes are any trace of fat (yolk, oil, or a not-fully-clean bowl) preventing the whites from whipping to full volume, or under-whipping so the meringue can't hold its structure. Room-temperature whites also whip better and more stably than cold ones straight from the fridge.
Is it safe to use egg whites that have been refrigerated for a week?
Past five days, the safety margin narrows even if there's no obvious spoilage sign — egg whites don't always show clear visual or smell cues before they turn. If you're at or past that window, it's safer to use them in a fully cooked application or discard them rather than in a raw or lightly-cooked meringue.
If you've got a large batch of whites and want to clear them fast, start with pavlova or a full meringue pie — both take four or more in one go. For smaller amounts, the egg white omelette or a small batch of amaretti will use two or three without much planning. Either way, egg whites are one of the more forgiving leftovers in a kitchen — they keep for days in the fridge and freeze cleanly, so there's rarely urgency to use them the same day.
