Instructions:
- Place the chicken breasts in the bottom of your slow cooker.
- Add the drained diced tomatoes, garlic, Italian seasoning, salt, and pepper over the chicken.
- Cover and cook on LOW for 4–6 hours or HIGH for 2–3 hours, until the chicken is tender.
- Shred or cube the chicken directly in the slow cooker, then stir in the heavy cream, Parmesan, mozzarella, and butter.
- Continue cooking for 15–20 minutes, or until the sauce becomes creamy and the cheeses are fully melted.
- Ladle into bowls and garnish with fresh parsley.
Variations
- Add spinach during the final 20 minutes for extra color and nutrients.
- Stir in sun-dried tomatoes for a richer, tangier flavor.
- Replace chicken breasts with chicken thighs for a more tender, juicy result.
- Add red pepper flakes for a subtle kick.
Tips
- Drain the tomatoes well to prevent thinning the sauce.
- Avoid overcooking the dairy—add cream and cheese only after the chicken is cooked.
- Adjust seasoning at the end to balance the richness of the sauce.
- Serve over pasta, mashed potatoes, or rice to enjoy every drop of the creamy Parmesan sauce.
