Ingredients

Soup Base

  • 2 tablespoons olive oil
  • 1 medium leek (white and pale-green parts only), halved lengthwise, sliced ½” thick
  • 2 celery stalks, sliced
  • 2 carrots, peeled and sliced
  • 1 clove garlic, peeled and chopped
  • 1 teaspoon thyme or rosemary (dried or fresh)
  • Zest of one lemon
  • 6 cups low-sodium chicken broth
  • Salt and freshly ground pepper to taste

Chicken

  • 1 lb skinless, boneless chicken thighs or breast*

Final Ingredients

  • ¾ cup orzo
  • 2 cups baby spinach
  • ¼ cup chopped fresh dill or parsley
  • Lemon halves (for serving)

Instructions

  1. Sauté Vegetables: Heat olive oil in a large heavy pot over medium heat. Add the leek, celery, and carrots. Cook, stirring often, until the vegetables are soft and fragrant, about 5 to 8 minutes.
  2. Add Aromatics: Stir in the chopped garlic, thyme or rosemary, and lemon zest. Cook for another minute to release the aromas.
  3. Cook Chicken: Add the whole chicken thighs or breast to the pot along with the chicken broth. Bring the mixture to a boil. Cover the pot, reduce heat to a simmer, and cook until the chicken is fully cooked through, about 15 to 20 minutes.
  4. Shred Chicken: Transfer the cooked chicken to a plate and let it cool slightly. Shred or chop the chicken into bite-sized pieces using two forks or a knife.
  5. Cook Orzo: Meanwhile, return the broth to a boil. Add orzo to the simmering broth and cook until al dente, around 8 to 10 minutes. Stir occasionally to prevent sticking.
  6. Combine and Finish Soup: Check seasoning and adjust salt and pepper as needed. Stir in the shredded chicken, baby spinach, and chopped dill or parsley. Simmer gently for a couple of minutes until the spinach wilts.
  7. Serve: Ladle the soup into bowls and serve with lemon halves or wedges on the side for squeezing fresh lemon juice over each serving.
  8. Storage and Reheating: Store leftovers in an airtight container in the refrigerator for 3 to 4 days. Reheat in the microwave or on the stovetop over medium heat, adding additional broth if the soup thickens too much.

Notes

  • To make an avgolemono (Greek lemon-egg) version of this soup, whisk together 2 eggs and the juice of 2-3 lemons (about ½ cup). With the pot off heat, gradually warm the egg mixture by adding a scoop of hot soup and whisking continuously. Then slowly stir the warmed egg mixture back into the soup to create a smooth, creamy texture.
  • Add extra vegetables such as green peas for additional color and flavor.
  • You can substitute the leek with one large yellow onion if preferred.
  • If using leftover roasted or rotisserie chicken, have approximately 3 cups of shredded chicken ready to add.
  • When storing or reheating, the soup may thicken as the starches absorb liquid; simply add more broth to reach desired consistency.
