Ingredients

This soup is made with simple, wholesome ingredients that come together beautifully for a flavorful and hearty dish.

  • 2 tablespoons olive oil
  • 1 small onion, diced
  • 2 carrots, peeled and diced
  • 2 celery stalks, diced
  • 3 cloves garlic, minced
  • 6 cups chicken broth
  • 1 can (14.5 ounces) diced tomatoes
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon red pepper flakes (optional, for heat)
  • Salt and black pepper, to taste
  • 2 cups cooked, shredded chicken (rotisserie or leftover chicken works well)
  • 3/4 cup orzo pasta
  • 2 tablespoons fresh parsley, chopped
  • Grated Parmesan cheese, for serving (optional)
  • Juice of 1/2 lemon (optional, for brightness)

Instructions

This soup is easy to prepare and comes together in just a few steps. Follow these instructions for a perfect, cozy meal:

  1. Sauté the vegetables:
    In a large pot, heat the olive oil over medium heat. Add the diced onion, carrots, and celery, and cook for about 5 minutes until the vegetables are softened. Stir in the minced garlic and cook for another 30 seconds until fragrant.
  2. Build the broth:
    Pour in the chicken broth and diced tomatoes, then add the oregano, basil, thyme, red pepper flakes (if using), salt, and black pepper. Stir well and bring the soup to a gentle simmer.
  3. Add the chicken:
    Stir in the shredded chicken and let the soup simmer for 10 minutes, allowing the flavors to meld together.
  4. Cook the orzo:
    Add the orzo pasta and continue to simmer for another 8–10 minutes, or until the pasta is tender but still slightly firm. Stir occasionally to prevent sticking.
  5. Finish the soup:
    Stir in the fresh parsley and, if desired, squeeze in the juice of half a lemon to brighten the flavors.
  6. Serve and enjoy:
    Ladle the soup into bowls and garnish with grated Parmesan cheese for an extra depth of flavor. Serve with crusty Italian bread or garlic toast for a complete meal.

Tweaks and Additions

Want to make this soup your own? Here are some variations and additions to suit your taste:

  • Make it creamy:
    Stir in 1/2 cup of heavy cream or a splash of half-and-half at the end for a richer, velvety texture. This gives the soup a luscious, creamy finish while still keeping it light and comforting.
  • Boost the greens:
    Add a handful of baby spinach or kale during the last few minutes of cooking for an extra dose of nutrients and color. The greens will wilt beautifully into the soup, enhancing its fresh, earthy flavor.
  • Try a different pasta:
    Instead of orzo, you can use ditalini, small shells, or even broken spaghetti to change up the texture while keeping the soup just as satisfying.
  • Use fresh herbs:
    Swap out dried oregano, basil, and thyme for fresh versions if you have them. Simply double the amount of fresh herbs to bring out their fragrant, vibrant flavors.
  • Add more vegetables:
    For a heartier soup, toss in chopped zucchini, bell peppers, or even mushrooms. These additions will add more texture and depth to each bite.
  • Go gluten-free:
    Replace the orzo with a gluten-free pasta or cooked quinoa for a wheat-free alternative that still delivers the same comforting experience.
  • Make it spicy:
    Increase the red pepper flakes or add a dash of hot sauce for a spicier version that brings a little heat to each spoonful.
  • Enhance the umami:
    Stir in a Parmesan cheese rind while the soup simmers. The rind will slowly melt into the broth, adding a deep, savory flavor that makes the soup even more delicious.
  • Use homemade broth:
    If you have homemade chicken broth on hand, use it instead of store-bought for a deeper, richer flavor that takes the soup to the next level.

This Italian chicken and orzo soup is a heartwarming dish that brings comfort with every spoonful.

Whether you’re enjoying it on a cold evening, serving it as a nourishing meal to loved ones, or simply craving something cozy and delicious, this soup is a must-try. Pair it with a slice of crusty bread and a sprinkle of Parmesan, and you have the perfect Italian-inspired comfort meal.
