Ingredients for Creamy Cajun Shrimp & Crab Pasta

Seafood Selection

Shrimp – peeled, deveined, and seasoned with Cajun spices. Medium or large shrimp work best.
Crab meat – opt for fresh lump crab if possible, but quality canned crab also works. Avoid imitation crab for the best flavor.

Pasta Base

Penne, fettuccine, or linguine are great choices. The sauce clings beautifully to these types of pasta.
Cook until al dente so it holds up well when mixed with the sauce.

Cajun Cream Sauce Essentials

Butter and olive oil
Onion and garlic for the flavor foundation
Cajun seasoning – either store-bought or homemade with paprika, cayenne, garlic powder, and thyme
Heavy cream (or half-and-half for a lighter version)
Parmesan cheese for that creamy, cheesy depth

Garnishes

Fresh parsley or green onions
A squeeze of lemon or lemon zest for brightness

Step-by-Step Instructions

Making Cajun Shrimp & Crab Pasta isn’t complicated, but following the right steps will give you restaurant-worthy results.

Cooking the Shrimp and Crab

Season shrimp generously with Cajun seasoning.
Heat butter in a skillet and sauté shrimp until pink and slightly crispy on the edges. Don’t overcook—they finish cooking quickly.
Set shrimp aside. Add crab later when the sauce is nearly done to keep it tender and intact.

Preparing the Pasta

Cook pasta in salted water until al dente.
Reserve about a cup of pasta water before draining—this can loosen the sauce if it’s too thick.

Making the Cajun Cream Sauce

In the same skillet, add butter and sauté garlic and onion until fragrant.
Sprinkle in Cajun seasoning, letting it bloom in the fat for maximum flavor.
Deglaze with chicken stock or a splash of white wine.
Stir in heavy cream, then add Parmesan cheese until the sauce is smooth and creamy.
Return shrimp to the pan and gently fold in crab meat.
Toss the cooked pasta with the sauce until evenly coated. If the sauce feels too thick, add a splash of pasta water.

Tips for the Best Cajun Shrimp & Crab Pasta

Watch the shrimp carefully. They only need 2–3 minutes per side. Overcooking makes them rubbery.
Add crab at the end. Stirring it too much can break apart the delicate meat.
Taste your Cajun seasoning. Some blends are spicier than others—start light and adjust to your preference.
Balance the sauce. If it’s too spicy, add more cream. If it feels too heavy, brighten it with lemon juice.
