Creating Crock Pot Creamy Cajun Chicken Pasta is a straightforward process if you follow these steps:

1. Prepare the Chicken: Place the chicken breasts in the bottom of the crock pot.
2. Add the Vegetables: Top the chicken with chopped onion, garlic, bell pepper, and cherry tomatoes.
3. Mix the Liquids: In a separate bowl, whisk together the chicken broth, heavy cream, and Cajun seasoning until well combined.
4. Combine Ingredients: Pour the creamy mixture over the chicken and vegetables in the crock pot. Season with salt and pepper as desired.
5. Cook: Cover and cook on low for 4 hours or high for 2 hours, until the chicken is thoroughly cooked and tender.
6. Shred the Chicken: Once cooked, shred the chicken directly in the crock pot using two forks, stirring it into the sauce.
7. Add Pasta: Stir in the uncooked pasta. If using penne or a similar shape, ensure it’s fully submerged in the sauce.
8. Final Cooking: Cover again and cook on high for an additional 30 minutes, or until the pasta is al dente.
9. Add Cheese: Stir in the grated Parmesan cheese and let it melt into the dish.
10. Serve: Taste for seasoning adjustments, adding more salt or pepper as needed before serving.

Following these steps will lead you to a delightful dish that combines creamy, savory flavors with a delightful kick of spice!
