Lemon Chicken Soup (Greek Avgolemono with Orzo and Egg, 45 Min)

Lemon chicken soup in a white bowl with shredded chicken, orzo pasta, silky lemon-egg broth, lemon slices, fresh dill garnish, golden surface from emulsified egg

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.

Ingredients

Serves 6.

For the soup base

  • 2 tbsp olive oil
  • 1 medium yellow onion, finely diced
  • 2 medium carrots, finely diced
  • 2 celery stalks, finely diced
  • 4 cloves garlic, minced
  • 8 cups good chicken broth (low-sodium preferred)
  • 1 lb boneless skinless chicken breasts or thighs
  • 1 cup orzo pasta
  • 1 tsp salt + 1/2 tsp pepper

For the avgolemono

  • 3 large eggs
  • 1/2 cup fresh lemon juice (about 3 large lemons)
  • Zest of 2 lemons

For garnish

  • 1/4 cup chopped fresh dill
  • Extra lemon wedges
  • Cracked black pepper + olive oil drizzle (optional)

Smart substitutions

  • Rotisserie chicken: Skip simmering and use 3 cups shredded rotisserie chicken — saves 20 min
  • Rice instead of orzo: 3/4 cup white rice — needs 20 min simmering time
  • Gluten-free: Sub gluten-free orzo or short-grain rice
  • Creamier version: Whisk in 1/4 cup heavy cream after the eggs for extra-silky finish

Step 1: Build the soup base

Heat olive oil in a large pot over medium heat. Add onion, carrots, and celery. Cook 6-8 minutes until softened. Add garlic; cook 1 more minute until fragrant.

Step 2: Simmer the chicken

Add chicken broth and chicken breasts. Bring to a boil, then reduce to a gentle simmer. Cover and cook 18-20 minutes until chicken reaches 165°F internal. Remove chicken to a cutting board.

Step 3: Cook the orzo

Bring broth back to a boil. Add orzo, salt, and pepper. Cook 9-10 minutes until pasta is just tender. Meanwhile, shred chicken with two forks.

Step 4: Make the avgolemono mixture

In a medium bowl, whisk eggs vigorously until light and frothy, 1 minute. Slowly whisk in lemon juice and zest. Mixture should be smooth and pale yellow.

Step 5: Temper the eggs

Remove pot from heat. Slowly ladle 2 cups of hot broth into egg mixture, whisking constantly. This warms the eggs without scrambling them. Pour tempered egg mixture back into the pot, whisking constantly.

Step 6: Add chicken and serve

Return shredded chicken to the soup. Stir gently over LOW heat 2 minutes to warm chicken — DO NOT BOIL or eggs will curdle. Taste and adjust salt and lemon. Ladle into bowls, garnish with dill, lemon wedges, pepper, and olive oil drizzle.

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.
