You can make a wide range of rich desserts, sauces, and even pasta dough with extra egg yolks, so they are very easy to use up rather than waste. Below are the most popular ideas, plus a quick forum-style roundup of what people actually do with leftover yolks.

Sweet recipes with yolks

Egg yolks shine in desserts because they add creaminess and richness.

  • Custards and pudding
    • CrĂšme brĂ»lĂ©e, baked custard cups, pot de crĂšme.
* Classic flan / leche flan uses many yolks and is great when you have a big batch to use.
  • Ice cream and gelato
    • “Custard-style” ice cream and gelato rely on egg yolks to thicken the base and give a silky texture.
  • Lemon or fruit curd and tarts
    • Lemon curd, lemon tarts, and other citrus curds use multiple yolks and keep well in the fridge.
  • Cakes, cookies, and rich doughs
    • Some cake recipes, cookies, and brioche-style doughs use extra yolks for color and tenderness.

Savory dishes and sauces

Yolks also deepen flavor in savory dishes and classic sauces.

  • Hollandaise and bĂ©arnaise
    • Classic hollandaise (for eggs Benedict, veggies, or fish) and bĂ©arnaise (for steak) are both yolk-based emulsified sauces.
  • Carbonara and other creamy pastas
    • Egg-yolk carbonara and other creamy pasta sauces use yolks to thicken the sauce without cream.
  • Homemade mayonnaise and aioli
    • Yolks are the base for mayonnaise, garlic aioli, and other flavored mayo-style sauces.
  • Enriched mashed potatoes and scrambles
    • Mixing a yolk into mashed potatoes or scrambled eggs makes them extra rich and golden.

Baking and dough uses

Bakers often treat yolks as a secret weapon for texture and color.

  • Egg wash / glaze
    • Whisk yolks with a little water or milk and brush on bread, pies, and pastries for a deep golden crust.
  • Pastry and pie dough
    • Shortcrust pastry or tart dough can include yolks to make the crust more tender and rich.
  • Bread and noodles
    • Egg breads like challah or brioche, and homemade egg noodles or pasta, often use extra yolks for a softer, richer result.

Quick ideas by number of yolks

If you only have a few yolks, you can still make something useful and tasty.

  • 1–2 yolks
    • Add to scrambled eggs, mashed potatoes, or a small batch of mayo.
    • Use as an egg wash for one loaf of bread or a pie.
  • 3–4 yolks
    • Small batch custard or pudding, lemon curd, or a rich pasta dough.
  • 5+ yolks
    • CrĂšme brĂ»lĂ©e, ice cream, flan, or a large batch of hollandaise for brunch.

Forum-style “what people actually do”

Home cooks online repeatedly suggest a few “go-to” moves for leftover yolks.

“Make pasta. You can use them all in one shot
 or make all-yolk carbonara.”

Common community favorites include:

  • Homemade pasta or noodles when you have several yolks.
  • Custards and flans for dessert, especially when baking for a group.
  • Hollandaise or bĂ©arnaise for a weekend brunch or steak night.

TL;DR: Use extra egg yolks for custards, ice cream, lemon curd, hollandaise, mayonnaise, rich pasta, and as a glossy egg wash so none of them go to waste.
