Ingredients

Ingredients: sausage, butter, Cajun seasoning, garlic powder, onion powder, chicken breasts, penne pasta, Parmesan cheese, heavy cream, chicken broth, heavy cream, and green onions.

Chicken breasts: We’re using boneless, skinless ones in this recipe.

Seasoning: We use Cajun seasoning, garlic powder, and onion powder. Adjust the amount of the Cajun seasoning to what you like for spiciness.

Andouille sausage (optional): Adds smoky, spicy flavor. Smoked sausage can be a good substitute if needed.

Heavy cream: Gives the sauce its creamy texture.

Chicken broth: Adds flavor and thins the sauce slightly.

Parmesan cheese: Freshly grated melts better than pre-shredded.

Butter: Adds richness and helps the sauce thicken slightly.

Pasta (penne or fettuccine): Use pasta that holds sauce well; penne works especially for soaking up creamy sauce.

Green onions (for garnish): Adds a fresh, mild onion flavor and a pop of color.

How to Make

Lightly spray the inside of your crockpot with nonstick spray.

Place the chicken breasts in the crockpot and season them with Cajun seasoning, garlic powder, and onion powder.

If using andouille sausage, arrange the sliced sausage around the chicken.
