A creamy tortellini soup with chicken, vegetables and parmesan cheese. If you love chicken alfredo you’ll love this soup!


  • 1 cup diced onion
  • 4 garlic cloves, minced
  • 8 cups chicken broth
  • 4 medium carrots, cut into 1/2 inch pieces
  • 4 celery ribs, cut into 1/2 inch pieces
  • 1 tsp salt
  • 1 tsp black pepper
  • 2 pounds boneless skinless chicken breasts (frozen is okay)
  • 1/2 cup flour
  • 2 cups half and half
  • 1 (19 oz) package frozen cheese tortellini
  • 1 1/2 cup grated/shredded parmesan cheese
  • 5 large kale leaves, washed and coarsely chopped (discard the stem)
  • Salt and pepper to taste


  1. Add onion, garlic, chicken broth, carrots, celery, salt, pepper and chicken into the slow cooker.
  2. Cover and cook on low for 6-8 hours (6 hours for thawed chicken and 8 hours for frozen chicken).
  3. Remove the lid and use tongs to place chicken on a cutting board. Cut the chicken into pieces or shred it and add it back into the slow cooker.
  4. Turn your slow cooker to high. Warm the half and half (I just do this in the microwave for 1 minute). Whisk the flour a tablespoon at a time into the half and half until it is a smooth mixture. Pour the mixture into the slow cooker. Let the soup thicken with the flour mixture for about 10 minutes.
  5. Add in the tortellini, parmesan and kale. Tortellini will cook in about 5-10 minutes. Salt and pepper to taste.
  6. Ladle into bowls and serve.


I used my 6 quart oval Kitchenaid slow cooker.*

An optional step is to saute the onion and garlic before adding it into the slow cooker. This will make a better flavored soup.

You can easily halve this recipe. Cut all the ingredients in half and cut the cooking time down by 1 hour.
