Lemon Chicken Orzo Soup

Lemon Chicken Orzo Soup—a bright, velvety, and incredibly comforting soup that’s like a cross between classic chicken noodle and the Greek avgolemono. It’s thick, hearty, and bursting with fresh lemon flavor, with tender shredded chicken and tiny pearls of orzo pasta in every spoonful.

This soup is famously soothing (often called “Greek penicillin”) but lively enough for any season. It comes together in one pot and tastes even better the next day.

Lemon Chicken Orzo Soup

Yields: 6-8 servings
Total Time: 45-50 minutes

Ingredients

For the Soup Base:

2 tablespoons olive oil or butter
1 medium yellow onion, finely diced
2 large carrots, peeled and diced small
2 celery stalks, diced small
4 cloves garlic, minced
8 cups (64 oz) low-sodium chicken broth
1 lb boneless, skinless chicken breasts or thighs (thighs stay juicier)
2 bay leaves
1 teaspoon dried oregano or thyme
Salt and freshly ground black pepper, to taste

For the Orzo and Finish:

1 cup dried orzo pasta
3 large eggs
1/3 to 1/2 cup freshly squeezed lemon juice (from about 2-3 lemons), adjust to your brightness preference
Zest of 1 lemon
2 tablespoons fresh dill, chopped (or 1 tsp dried dill)
Fresh parsley, for garnish

Instructions

1. Sauté the Aromatics

Heat the olive oil in a large Dutch oven or heavy-bottomed pot over medium heat.
Add the onion, carrots, and celery. Cook, stirring occasionally, until the vegetables are softened and the onion is translucent, about 6-8 minutes.
Add the minced garlic and cook for 1 minute more, until fragrant.

2. Build the Soup and Poach the Chicken

Pour in the chicken broth. Add the bay leaves and dried oregano.
Add the whole, raw chicken breasts/thighs directly into the pot. Season the broth generously with fresh black pepper. Hold off on salting heavily until the end, as the broth will reduce slightly.
Bring the soup to a gentle boil, then reduce the heat to a simmer. Cover and cook for 15-20 minutes, or until the chicken is completely cooked through (internal temp of 165°F).

3. Shred the Chicken and Cook the Orzo

Remove the cooked chicken from the pot and set it on a cutting board to cool slightly. Discard the bay leaves.
Bring the soup back up to a gentle boil. Stir in the 1 cup of dried orzo pasta. Cook, uncovered, at a low boil for 8-10 minutes, or until the orzo is tender but still has a slight bite (al dente). Stir occasionally to prevent sticking.
While the orzo cooks, shred the chicken with two forks into bite-sized pieces.

4. Temper the Eggs (The Most Important Step)

In a medium heatproof bowl, whisk the 3 eggs vigorously until they are very smooth, frothy, and lightened in color, about 1-2 minutes.
Slowly whisk the fresh lemon juice and lemon zest into the beaten eggs.
Now, the tempering: While whisking the egg-lemon mixture constantly and vigorously, use a ladle to very slowly drizzle in about 2 cups of the hot broth from the soup pot. You must add it in a thin, steady stream. This gently warms the eggs without scrambling them.
The egg-lemon mixture should now be warm and creamy.

5. Finish the Soup

Reduce the heat under the soup pot to the lowest possible setting (you don’t want it to boil after adding the egg mixture, or it could curdle).
Pour the warm, tempered egg-lemon mixture back into the soup pot in a slow, steady stream, stirring the soup constantly. You’ll see the broth transform from clear to a silky, creamy, pale yellow.
Add the shredded chicken back to the pot. Stir in the fresh dill.
Heat the soup gently for 2-3 minutes to let the flavors meld, but do not let it boil. Boiling can cause the eggs to curdle and the soup to lose its velvety texture.
Taste the soup and season with salt and additional pepper as needed.

6. Serve

Ladle the soup into bowls and garnish with chopped fresh parsley and an extra crack of black pepper. A drizzle of good olive oil on top is also lovely.

The Science of Silky Avgolemono (No Cream!)

This soup gets its signature creaminess not from dairy, but from the emulsification of eggs and lemon juice with hot broth. It’s a classic Greek technique called avgolemono. The key to success is tempering: slowly raising the temperature of the egg mixture so it thickens the soup into a velvety sauce rather than turning into scrambled egg threads. Take your time with the ladle, and keep that whisk moving.

Tips for the Best Soup

Fresh Lemon is Non-Negotiable: Bottled lemon juice will give this a harsh, metallic taste. Use fresh-squeezed lemons and zest them before juicing. The zest carries an intense lemon oil that brightens the whole pot without extra acidity.
Orzo Warning: Orzo absorbs liquid like crazy. If you are making the soup ahead of time or anticipate leftovers, the orzo will swell. You have two excellent options:
- Method 1 (For serving immediately): Cook the orzo directly in the soup as written above.
- Method 2 (For meal prep/leftovers): Cook the orzo in a completely separate pot of salted water, drain it, and stir it into individual bowls when serving. This keeps the orzo from bloating and turning your soup into a solid mass in the fridge.
Chicken Shortcut: A shredded rotisserie chicken works beautifully here. Skip the chicken-poaching step and add 3-4 cups of shredded, cooked chicken at the very end, after the orzo is cooked. Use good-quality boxed broth since you won’t be building flavor from poaching.

Variations

Extra Creamy: If you’re not strictly avoiding dairy, a swirl of heavy cream or a pat of butter stirred in at the very end makes this incredibly decadent.
Greens: Stir in two big handfuls of fresh baby spinach or chopped kale at the end. The residual heat will wilt it perfectly.
Turkey Lemon Orzo: The absolute best use for Thanksgiving turkey carcass. Make a rich turkey broth, and use leftover shredded turkey instead of chicken.
Rice Instead of Orzo: If you’re gluten-free, substitute the orzo with 3/4 cup of long-grain white rice. You’ll need to simmer it for about 15-20 minutes until tender, before tempering the eggs.

This soup is a hug in a bowl, balancing cozy comfort with a bright, lemony lift. Enjoy! Let me know if you have questions.
