This is the soup I make when I have a cold and want something both nourishing and dramatically delicious. Lemon chicken soup is the Greek classic Avgolemono with tender shredded chicken, plump orzo pasta, all in a silky lemon-egg broth that’s somehow both bright and creamy without any cream. The secret is tempering eggs with hot broth and lemon juice — a 5,000-year-old Mediterranean technique. 45 minutes of soul-warming comfort.
Fun fact: avgolemono (αυγολέμονο) literally translates to “egg-lemon” in Greek and is one of the oldest known recipes in Western cuisine — historians trace it back to ancient Sephardic Jewish cooking in Spain (called “agristada”) before the Inquisition pushed Sephardic Jews to Greece, where they popularized the technique. It predates modern French sauce traditions by centuries and is considered the first emulsified sauce in human history.
Why this recipe works
- Temper eggs slowly with hot broth. Adding eggs straight to boiling soup = scrambled eggs. Whisking small amounts of hot broth into the egg-lemon mixture first warms them safely.
- Take soup off heat for the final mix. The egg cooks the soup — boiling after adding eggs curdles them. Off-heat addition gives silky, never-grainy texture.
- Use both lemon zest and juice. Zest contains aromatic oils (the perfume); juice contains the acid. Together they create three-dimensional citrus flavor that pure juice can’t.

Pro tips for perfect avgolemono
- Take pot OFF heat before adding eggs. The #1 mistake — boiling soup curdles eggs. Off heat keeps the texture silky.
- Whisk eggs until very frothy. Aerating the eggs first makes the final soup lighter and more emulsified.
- Use fresh lemon, never bottled. Bottled lemon juice tastes flat and metallic compared to fresh — and you need the zest anyway.
- Adjust thickness with broth. Soup thickens significantly as it cools. Thin with extra hot broth when reheating.
Frequently asked questions
Why did my soup curdle?
You added eggs to boiling soup, or boiled the soup after adding eggs. Always: take pot off heat, temper eggs slowly with hot broth, return to LOW heat (never boil) after combining. If it curdles, blend with an immersion blender to smooth.
How long does it keep?
Refrigerator 3 days. Reheat very gently on LOW heat or 50% power microwave to avoid scrambling the eggs. Eggs may slightly curdle on reheating, but flavor stays great.
Can I freeze it?
Not recommended — the egg-lemon emulsion breaks on freezing and creates grainy texture. If you must, freeze before adding eggs/lemon, then temper in fresh eggs when reheating.
What is orzo?
Orzo is small rice-shaped pasta (the word means “barley” in Italian). Find it next to other pasta. Substitute pearl couscous, ditalini, or even risotto rice (extends cook time by 10 minutes).
Can I make it dairy-free?
It already is! Traditional avgolemono uses only broth, eggs, and lemon — no dairy needed. The eggs create the creamy emulsion that mimics dairy texture.
How tart should it be?
Properly made avgolemono is bracingly lemony — that’s the point. Start with 1/2 cup juice; taste; add more if you like. Greek grandmas use up to 3/4 cup for very tart versions.
