Making Slow Cooker Creamy Tomato Basil Chicken is a breeze when you follow these easy steps:

1. Prepare the Slow Cooker: Grease the inside of your slow cooker with a little olive oil or cooking spray to prevent sticking.
2. Add Chicken: Place the chicken breasts in the bottom of the slow cooker.
3. Mix Ingredients: In a separate bowl, combine the diced tomatoes (with their juice), heavy cream, chicken broth, garlic powder, onion powder, salt, and black pepper. Stir until well mixed.
4. Combine in Slow Cooker: Pour the mixture over the chicken, ensuring it’s well coated.
5. Add Basil: Sprinkle the chopped basil over the top of the mixture.
6. Cook: Cover the slow cooker and set it to low for 4-6 hours or high for 2-3 hours.
7. Check for Doneness: When the chicken is fully cooked (internal temperature should reach 165°F), remove it from the slow cooker and shred it with two forks.
8. Return Chicken to Sauce: Stir the shredded chicken back into the creamy sauce.
9. Add Cheese: Mix in the grated Parmesan cheese until melted and creamy.
10. Serve: Spoon the creamy chicken mixture over your choice of cooked pasta or rice.
