Ingredients
  

  • 1 1/2 pounds boneless skinless chicken breasts
  • 12 oz medium pasta shells uncooked
  • 2 cups low-sodium chicken broth
  • 1 1/2 cups heavy cream
  • 1 cup Parmesan cheese freshly grated, plus more for serving
  • 1/4 cup roasted garlic cloves or paste, mashed
  • 1 tsp Italian herb blend dried
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1 tsp kosher salt plus more to taste
  • 1/2 tsp black pepper freshly ground
  • 2 tbsp unsalted butter cut into small pieces
  • 2 tbsp fresh parsley chopped, optional garnish

Instructions
 

  • Lightly spray a 6-quart slow cooker with nonstick cooking spray.
  • Spread the uncooked pasta shells evenly across the bottom of the slow cooker.
  • Place the chicken breasts on top of the pasta shells.
  • In a bowl, whisk together chicken broth, heavy cream, Parmesan cheese, roasted garlic, Italian herbs, garlic powder, onion powder, salt, and pepper.
  • Pour the creamy mixture evenly over the chicken and pasta, ensuring most shells are covered.
  • Dot the top with small pieces of butter.
  • Cover and cook on LOW for 3 1/2 to 4 1/2 hours or HIGH for 2 to 2 1/2 hours until the chicken is cooked through and the pasta is tender.
  • Remove the chicken, shred it with two forks, then return it to the slow cooker.
  • Stir well to coat the pasta and chicken in the creamy sauce.
  • Let the mixture rest on the warm setting for 5–10 minutes to thicken slightly before serving.
  • Serve topped with extra Parmesan cheese and chopped parsley if desired.

Notes

If the sauce becomes too thick, stir in a splash of warm chicken broth or cream before serving.
