Creating this incredible Crock Pot Chicken Spaghetti is straightforward. Follow these easy steps:

1. Prepare the Chicken: Place the boneless, skinless chicken breasts at the bottom of the crock pot.

2. Add Vegetables: Sprinkle the chopped onion, diced bell pepper, and minced garlic over the chicken.

3. Mix the Sauces: In a separate bowl, combine the cream of mushroom soup, diced tomatoes, chicken broth, Italian seasoning, salt, and pepper. Stir well.

4. Combine Ingredients: Pour the sauce mixture evenly over the chicken and vegetables in the crock pot.

5. Cook: Cover the crock pot and set it to cook on low for 6-8 hours or high for 3-4 hours.

6. Add Pasta and Cheese: About 30 minutes before serving, break the uncooked spaghetti into smaller pieces and add it to the crock pot. Stir to incorporate.

7. Melt the Cheese: In the last 10 minutes of cooking, sprinkle the shredded cheddar cheese on top. Cover again until the cheese is melted.

8. Shred Chicken: Before serving, use two forks to shred the chicken within the crock pot thoroughly. Mix everything together.
