Step-by-Step Instructions
- Sauté the Chicken:
- Pat the chicken dry to ensure it browns well then generously season with Cajun seasoning smoked paprika salt and pepper. Press grated Parmesan onto each piece to create a flavorful crust. Heat olive oil and two tablespoons of butter in a skillet over medium-high heat. Cook chicken for four to six minutes until golden and cooked through adding a tablespoon of butter and half the garlic in the last minute to infuse flavor. Remove chicken and set aside.
- Build the Sauce:
- In the same skillet add remaining butter and garlic and sauté for 30 seconds until fragrant. Pour in heavy cream and chicken broth and stir to combine. Bring to a simmer then whisk in softened cream cheese until smooth.
- Add the Cheese:
- Gradually stir in mozzarella cheddar and Parmesan cheeses mixing until the sauce is thick and creamy. Season with Italian seasoning dried basil and optional red pepper flakes. Taste and adjust salt and pepper as needed. Let simmer for another two to three minutes.
- Cook and Combine Pasta:

Storage Tips
Store any leftovers in an airtight container in the refrigerator for up to three days. Reheat gently on the stove adding a splash of milk or broth to loosen the sauce if it thickens too much. This dish also freezes well; thaw overnight in the fridge before reheating.
Ingredient Substitutions
Chicken thighs can be used for a juicier option though cooking time will be slightly longer. If you want less spice omit or reduce the Cajun seasoning and red pepper flakes. Use part-skim cheeses if you prefer to lower fat content. Heavy cream can be swapped with half-and-half but the sauce will be lighter and less rich.
Serving Suggestions
Pair this pasta with a simple green salad dressed in lemon vinaigrette for brightness or roasted vegetables like asparagus or broccoli. Garlic bread is a classic side that complements the creamy sauce perfectly. Finish with a crisp white wine such as Sauvignon Blanc to cut through the richness.
