Layer the Base: Begin by placing the chicken breasts flat at the bottom of your crockpot. These will create a flavorful base as they cook in the broth.
Add the Broth: Pour the chicken broth over the chicken breasts, ensuring they are completely submerged for even cooking.
Incorporate Vegetables and Seasonings: Add the diced tomatoes, minced garlic, and diced onion into the pot. Sprinkle in the Italian seasoning, then stir gently to combine all the ingredients evenly.
Cook: Cover the crockpot with its lid and set the heat. Cook on the low setting for 6-7 hours or on high for 3-4 hours, until the chicken is thoroughly cooked and reaches an internal temperature of 165°F (75°C).
Shred the Chicken: Once the chicken has cooked, carefully remove it from the crockpot using tongs. Shred the chicken into bite-sized pieces using two forks, then return the shredded chicken back into the broth mixture.
Add Tortellini and Cream: Stir in the frozen tortellini and pour in the heavy cream, mixing well to combine. Cover the crockpot again and cook on high for an additional 30 minutes, or until the tortellini is tender and cooked through.
Final Seasoning: Before serving, taste the dish and adjust the seasoning with salt and pepper as desired.
Garnish and Serve: Ladle the Chicken Tortellini Delight into bowls and garnish with fresh basil leaves. Top each serving with a generous sprinkle of grated Parmesan cheese for added flavor.
