Start by preparing the ingredients: chop the onions, slice the carrots, and mince the garlic.
Place the boneless, skinless chicken breasts at the bottom of the Crock Pot.
Add the diced tomatoes, sliced carrots, diced onion, and minced garlic over the chicken.
Pour in the chicken broth, and season with dried basil, dried oregano, salt, and pepper. Stir gently to combine.
Cover the Crock Pot and cook on low for 6 hours or until the chicken is cooked through and tender.
Once cooked, remove the chicken breasts from the pot and shred them using two forks. Return the shredded chicken to the soup.
Add the heavy cream and grated Parmesan cheese to the pot, stirring well until the cheese is melted and the soup is creamy.
For a heartier meal, add the cooked pasta to the soup and stir to combine.
Serve hot, garnished with fresh parsley if desired.
