Step 1

Heat olive oil in a large Dutch oven over medium heat. Add onion and sauté until softened, about five minutes. Season with salt and pepper.

Step 2

Add chicken broth and bring to a boil.

Step 3

Add orzo to boiling broth and cook until tender, 8-10 minutes.

Step 4

While the orzo is cooking, whisk together the eggs and lemon juice in a large, heatproof bowl.

Step 5

Once the orzo is cooked through, reduce the heat until the soup is at a gentle simmer. Temper the eggs by slowly adding one cup of hot broth to the egg-and-lemon mixture while whisking. Then, slowly add the tempered egg mixture back to the Dutch oven. (This will prevent the eggs from curdling in the hot liquid.) Note: It is important not to rush this process and whisk throughout, to ensure the eggs emulsify.

Step 6

Add the cooked chicken to the soup and simmer until heated through. Do not allow soup to boil at any point after adding the eggs, which could cause the soup to break or curdle.

Step 7

Taste and adjust seasoning. Serve hot, garnished with fresh dill.
