In a crockpot, combine the chicken breasts, minced garlic, crushed tomatoes, tomato sauce, salt, pepper, Italian seasoning, and chicken broth.
Cover and cook on low for 6-8 hours or high for 3-4 hours.
Once the chicken is cooked through, shred the chicken with two forks and stir in the parmesan cheese, heavy whipping cream, and rotini pasta.
Cover and cook on low for an additional 30 minutes or high for 15 minutes.
While the soup is cooking, sauté the bread crumbs in butter in a saucepan on the stovetop until golden brown.
Serve the soup topped with shredded mozzarella and the sautéed bread crumbs.
