Ingredients
- 12 oz rigatoni pasta
- 2 tbsp olive oil
- 1 lb chicken breast or shrimp (optional)
- 2 tsp Cajun seasoning (adjust to taste)
- 2 tbsp butter
- 4 cloves garlic, minced
- 1 ½ cups heavy cream
- 1 cup milk
- 1 cup grated Parmesan cheese
- Salt and black pepper to taste
- ½ tsp paprika (optional for color)
- Fresh parsley or chives for garnish
Instructions

Cook the rigatoni according to package directions until al dente. Drain and set aside. In a large skillet, heat olive oil over medium-high heat. Season the chicken or shrimp with Cajun seasoning and sauté until cooked through. Remove from the pan and set aside. In the same skillet, melt butter and sauté garlic until fragrant. Add heavy cream and milk, stirring constantly. Gradually whisk in Parmesan cheese until the sauce turns silky and thick. Season with salt, pepper, and a pinch of paprika. Return the chicken or shrimp to the sauce, then toss in the rigatoni. Coat evenly and cook for another 2–3 minutes until everything is creamy and well combined. Garnish with parsley and serve hot.
You Must Know
- Don’t overcook the pasta, it will continue to soften in the sauce.
- Use freshly grated Parmesan for the smoothest sauce texture.
- Taste your Cajun seasoning before adding, some blends are saltier or spicier than others.
Storage Tips
Store leftovers in an airtight container for up to 3 days in the refrigerator. Reheat on the stovetop with a splash of milk or cream to loosen the sauce. Avoid freezing, as cream-based sauces may separate when thawed.
Ingredient Substitutions
- Protein: Replace chicken with shrimp, sausage, or tofu.
- Dairy-free: Use coconut cream and nutritional yeast instead of heavy cream and Parmesan.
- Spice level: Adjust Cajun seasoning to your liking or mix mild paprika with garlic powder for a lighter version.
- Pasta: Penne, fettuccine, or linguine work just as well if rigatoni isn’t available.
