This creamy Cajun Shrimp Mac and Cheese brings together tender macaroni pasta, spicy sautéed shrimp, and a luscious cheese sauce under a golden, buttery breadcrumb topping. It is pure comfort with a touch of heat, perfect for cozy dinners or when you want to impress someone with bold Southern flavors.
The first time I made this, my family devoured it so fast I barely got a bite. Now it is our go-to for Sunday dinners when everyone wants something both decadent and a little spicy.
Ingredients
- Elbow macaroni: Look for pasta with a rough surface to help the sauce cling better
- Large shrimp: Choose fresh or frozen wild-caught shrimp for best texture and flavor

You Must Know
- High in protein thanks to shrimp and cheese
- Great for make-ahead entertaining
- Topping stays crisp if broiled right before serving
My favorite part is that smoky kick from the paprika and flavorful Cajun shrimp Sometimes the whole family gets involved in sprinkling the topping before the dish goes under the broiler it always feels like a mini celebration at the dinner table
Storage Tips
Store leftovers in an airtight container in the fridge for up to three days To reheat add a splash of milk and warm gently on the stove or microwave covering loosely so the sauce stays creamy The breadcrumb topping is crispiest when freshly broiled
Ingredient Substitutions
Swap in gluten-free elbow macaroni or panko if needed Monterey Jack can be replaced with mozzarella Cream cheese can be left out for a lighter sauce Chicken or tofu works instead of shrimp for different dietary needs Just keep an eye on the broiling time so the proteins do not overcook
Serving Suggestions
Serve with crisp green salad or garlic bread to balance out the richness If you are feeling extra Southern add a scoop of coleslaw or some sautéed greens For special occasions I like pairing it with a glass of cold white wine
