Ingredients
  

  • 2 sticks celery finely chopped
  • 2 medium carrots peeled and finely chopped
  • 0.5 medium onion chopped
  • 1 tablespoon butter
  • 1 tablespoon olive oil
  • 3 cloves garlic minced
  • 2 tablespoons all-purpose flour
  • 6 cups chicken broth low sodium is great if you're watching salt intake!
  • 0.25 teaspoon Italian seasoning
  • 1.5 pounds boneless, skinless chicken breasts
  • 1 cup orzo pasta uncooked
  • 1 tablespoon fresh lemon juice or to taste
  • 1 tablespoon fresh parsley chopped, or to taste
  • Salt to taste
  • Freshly ground black pepper to taste

Equipment

  • Large Soup Pot
  • Tongs
  • Slotted spoon
  • Cutting Board

Method
 

  1. Step 1: Heat butter and olive oil in a large soup pot over medium-high heat. Add finely chopped celery, carrots, and onion. Sauté for about 5-7 minutes until softened and translucent.
  2. Step 2: Stir in minced garlic and cook for 30 seconds until fragrant. Immediately sprinkle in all-purpose flour and cook, stirring constantly, for 1 minute to create a roux.
  3. Step 3: Gradually pour in chicken broth, stirring continuously until smooth and lump-free. Add Italian seasoning and carefully place whole chicken breasts into the pot. Bring the soup to a gentle boil.
  4. Step 4: Once boiling, reduce heat to low, cover the pot (leaving it slightly ajar), and simmer for about 15 minutes to cook the chicken through and infuse flavors.
  5. Step 5: After 15 minutes, remove the lid. Stir in the uncooked orzo pasta. Continue to cook for another 10 minutes, or until the orzo is perfectly al dente, stirring occasionally to prevent sticking.
  6. Step 6: Carefully remove the cooked chicken breasts from the pot using tongs or a slotted spoon. Place on a cutting board, then shred with two forks or cut into bite-sized pieces. Return the chicken to the soup.
  7. Step 7: Stir in fresh lemon juice (start with 1 tablespoon, then add more to taste) and chopped fresh parsley. Season the soup with salt and freshly ground black pepper to taste.
  8. Step 8: Serve immediately, garnished with extra fresh parsley or a lemon slice if desired. Enjoy!

Notes

Substitutions & Additions: For convenience, use cooked rotisserie chicken or boneless, skinless chicken thighs. For a vegetarian version, substitute chicken with cannellini beans or chickpeas and use vegetable broth. Add quick-cooking vegetables like spinach (wilted at the end), frozen peas (with orzo), or chopped zucchini. Small pasta shapes like ditalini or alphabet pasta can replace orzo. A pinch of red pepper flakes adds warmth. For a creamier soup, stir in heavy cream or Greek yogurt off the heat. Fresh thyme or rosemary can be used instead of Italian seasoning.
Tips for Success: Avoid overcooking orzo to prevent mushiness; stir occasionally. Fresh lemon juice is crucial for the soup's bright flavor; consider adding zest too. Season throughout and at the end, as broth sodium varies. Simmering chicken breasts whole keeps them tender and juicy. You can prep vegetables ahead of time.
Storage & Meal Prep: Cool completely and store in an airtight container in the refrigerator for 3-4 days. For freezing (up to 3 months), undercook orzo slightly or cook it separately to avoid mushiness upon reheating. Thaw overnight and reheat gently on the stovetop, adding extra broth or water if needed. For meal prep, cooking orzo separately and adding it to individual servings prevents it from absorbing too much broth.
