Creating Crockpot Garlic Parmesan Chicken Pasta is simple when you follow these steps:

1. Prepare the Chicken: Place the boneless, skinless chicken breasts in the bottom of the crockpot.
2. Add the Broth: Pour the chicken broth over the chicken.
3. Season: Sprinkle minced garlic, Italian seasoning, black pepper, and salt over the chicken.
4. Cook the Chicken: Cover the crockpot and cook on low for 4-5 hours or on high for 2-3 hours, until the chicken is cooked through and tender.
5. Shred the Chicken: Once cooked, remove the chicken from the crockpot and shred it with two forks. Return the shredded chicken to the crockpot.
6. Stir in Cream and Cheese: Add heavy cream and grated parmesan cheese to the crockpot. Stir until well combined.
7. Cook the Pasta: Add the uncooked penne pasta directly into the crockpot along with frozen peas (if desired). Stir to combine and cover.
8. Final Cooking: Allow the pasta to cook on high for an additional 30-40 minutes, or until the pasta is tender.
9. Serve and Garnish: Once the pasta is cooked, stir well and garnish with fresh parsley before serving.
