Method
Slow-cook the chicken and soup base
- Place the boneless skinless chicken breasts in the slow cooker.
- Add crushed tomatoes, diced tomatoes, chicken broth, onion, garlic, dried basil, dried oregano, red pepper flakes, salt, and black pepper to the slow cooker.
- Cover and cook on low for 6–7 hours or high for 3–4 hours, until the chicken is tender and easily pulls apart.
Shred and finish with pasta
- Remove the chicken, shred it with two forks, and return the shredded chicken to the slow cooker.
- Stir in the cooked penne pasta and heat through for 10 minutes on high, until hot throughout.
Serve with toppings
- Ladle the soup into bowls.
- Top each bowl with shredded mozzarella cheese, grated Parmesan cheese, toasted Italian breadcrumbs, and fresh basil for garnish so the mozzarella melts into the hot soup.
Notes
For best texture, add penne pasta only after the chicken is shredded so it doesn’t get too soft in the slow cooker. Store leftovers in the refrigerator up to 4 days; reheat gently. Freezing is not recommended because pasta can turn soft when thawed. For a lighter option, use part-skim mozzarella and reduce breadcrumbs to 1/4 cup per serving.
