Avgolemono
αβγολέμονο · A foundational Greek warm emulsion sauce built from raw eggs, fresh lemon juice, and the hot cooking broth of the dish it will finish. It is used as a thickening and flavoring liaison stirred into soups, stews, and stuffed dishes at the end of cooking, never boiled once assembled.
The formula
1 yolk : 1 tbsp lemon : ~½ cup broth (≈ 2 eggs : 1 lemon : 1 L broth)
Ratio varies with desired thickness; more broth yields a thinner finishing sauce, less broth yields a velvety thickener. Lemon juice may be split — some added to the yolks, some added at the end for taste control.
Identity
- Greek in origin; name = avgo (egg) + lemoni (lemon), pronounced ah-vgoh-LEH-moh-noh
- A warm egg-and-lemon emulsion/liaison, not a cooked sauce
- A finishing/thickening agent stirred into hot dishes off the heat, not served standalone
- The defining thickener across the Greek soup and stew repertoire
- Never boiled after assembly — eggs coagulate gently between roughly 70–75 °C
- Can be made frothy (whipped whites) or smooth (whole eggs or yolks only)
Ingredients
| Base | Egg yolks (or whole eggs) | Primary emulsifier and thickener; yolks give a richer, silkier sauce, whole eggs give a lighter, frothier one. |
| Acid | Fresh lemon juice | Defining flavor; also helps stabilize the egg emulsion and balances richness. |
| Liquid | Warm broth (chicken, lamb, or fish) | Diluent, flavor base, and the tempering medium — must be from the dish being finished whenever possible. |
| Enrichment | Egg whites | Whipped with a little lemon juice to soft-meringue for the traditional frothy avgolemono style. |
| Fat | Extra-virgin olive oil | About 1 tsp added by some cooks (e.g. The Greek Food) for a slightly rounder mouthfeel. |
| Thickener | Rice or orzo starch | Not in the sauce itself but carried over from the host dish (e.g. avgolemono soup) and contributes to the final body once the liaison is stirred in. |
Method
- 1Crack the eggs; separate yolks from whites if making the frothy style, otherwise use whole. Whisk yolks (or whole eggs) with most of the lemon juice until pale, homogenous, and slightly thickened.Builds the egg-lemon emulsion base and evenly distributes the acid that will later help the eggs coagulate gently.
- 2Whip the whites separately with a small spoonful of lemon juice to soft, stable peaks if a frothy avgolemono is desired.The whipped whites fold in as air, producing the characteristic foam that distinguishes the traditional frothy style.
- 3Bring the broth to a hot but not rolling simmer; ladle a thin stream of the hot broth into the egg-lemon mixture a little at a time, whisking constantly.Gradual tempering raises the temperature of the eggs slowly so they do not scramble when they meet the hot pot.
- 4Once the egg mixture is warm and fluid, pour it back into the saucepan with the remaining broth (or into the host dish) off the heat, whisking steadily.Completes the incorporation in a large volume of liquid, preventing localized overheating of the eggs.
- 5Return the pot to very low heat and warm gently, stirring, just until the soup or sauce thickens and turns creamy and glossy.Eggs set into a velvety network between roughly 70–75 °C; going higher scrambles them and breaks the sauce.
- 6Fold in the whipped whites at the end if using them; taste and adjust with the reserved lemon juice and salt just before serving.Adds the signature froth without deflating it, and lets the cook dial the final brightness to taste.
Techniques that matter
Tempering
Slowly raising the eggs' temperature with hot broth prevents the proteins from coagulating into curds and preserves a smooth emulsion.
Whisked egg-lemon emulsion
Beating yolks with lemon juice creates a stable base that thickens predictably when gently warmed with broth.
Off-heat finishing
Combining the liaison with the host dish off direct high heat protects the eggs from scrambling and keeps the sauce glossy.
Variations & derivatives
Frothy avgolemonoTraditional / Kopiaste
Whites beaten to a soft meringue with lemon juice, yolks and remaining lemon added, then hot broth whisked in — yields a foamy, cloud-like sauce.
Smooth avgolemonoKopiaste (preferred style)
Whole eggs used unseparated, whisked with lemon juice and tempered with hot broth — yields a velvety sauce without foam.
Olive-oil avgolemonoThe Greek Food
A teaspoon of extra-virgin olive oil whisked in for a rounder, slightly richer mouthfeel.
Lamb-broth avgolemonoMagiritsa / Easter tradition
Made with the hot broth from simmered lamb offal and greens, giving a deeper, gamier base for the Easter soup.
Fish-broth avgolemonoCoastal Greek cooking
Built on hot fish stock and used to finish fish soups (psarosoupa) and seafood stews.
Used in these dishes
Substitutions
- Chicken broth → Lamb or fish broth — Use the broth of the dish being finished so the sauce echoes the host flavor — this is the traditional approach.
- Fresh lemon juice → Bottled lemon juice — Works in a pinch but loses the brighter, fresher aromatics of just-squeezed lemons.changes result
- Egg yolks only → Whole eggs — Produces a lighter, less rich sauce; add an extra egg to compensate if a thicker result is desired.
- Rice → Orzo or kritharaki — Interchangeable starch carriers in host dishes such as avgolemono soup.
Troubleshooting
Eggs scramble into curds in the sauce
Broth added too hot or too quickly to the eggs, or the finished sauce was boiled → Temper more gradually with cooler broth and never let the finished sauce boil; strain curds out and start over if severe.
Avgolemono is thin and watery
Too much broth per egg, or undercooked → Whisk an extra yolk with lemon juice and temper it in, or gently reduce by simmering briefly before adding the liaison.
Avgolemono is bland or flat
Not enough lemon, or using a broth low in flavor → Reserve a portion of lemon juice to adjust at the end and taste before serving; boost with a pinch of salt.
Sauce has no froth when a frothy style is desired
Whites were not separated and whipped, or were folded in after deflating →
