What Kind of Cajun Seasoning Should I Use?

The star of this dish is the Cajun seasoning, and while store-bought blends are convenient, making your own gives you complete control over the flavor and spice level. A good mix typically includes paprika, cayenne, garlic powder, onion powder, thyme, oregano, and black pepper. If you’re using a store brand, check the sodium content—some can be quite salty. Choose a blend that matches your heat tolerance, or go bold if you’re up for a fiery kick.

Cajun Seasoning – The heart of the dish’s flavor profile. Make your own or use your favorite blend.

How To Make the Creamy Cajun Shrimp Pasta

Step 1: Season and Sear the Shrimp

In a bowl, toss the shrimp with Cajun seasoning until well coated. Heat olive oil and a bit of butter in a large skillet over medium-high heat. Add the shrimp in a single layer and cook for about 2-3 minutes per side, until they turn pink and lightly charred. Remove and set aside.

Step 2: Cook the Pasta

While the shrimp is searing, boil the pasta according to package directions until al dente. Reserve about a cup of pasta water before draining, then set the pasta aside.

Step 3: Sauté the Garlic

In the same skillet used for the shrimp, reduce the heat to medium and melt a tablespoon of butter. Add the minced garlic and sauté for about 30 seconds, just until fragrant.

Step 4: Make the Cajun Cream Sauce

Pour in the heavy cream and bring it to a gentle simmer. Stir in Parmesan cheese and another spoonful of Cajun seasoning. Whisk continuously until the cheese melts and the sauce begins to thicken. Use a splash of reserved pasta water to loosen the sauce if needed.

Step 5: Combine Everything

Add the cooked pasta into the skillet and toss until it’s thoroughly coated with the sauce. Gently fold the shrimp back into the skillet. Cook for another 1-2 minutes to ensure everything is heated through and well combined.

Step 6: Garnish and Serve

Sprinkle freshly chopped parsley over the top and a bit more Parmesan if desired. Serve hot and enjoy every creamy, spicy bite.

Serving and Storing This Creamy Cajun Shrimp Pasta

Creamy Cajun Shrimp Pasta is best served immediately while the sauce is hot and velvety. Pair it with a crisp green salad or garlic bread to round out the meal. If you’re hosting, consider a chilled white wine like Sauvignon Blanc or Pinot Grigio to complement the spice and richness.

To store leftovers, let the pasta cool completely, then transfer it into an airtight container. It will keep well in the fridge for up to 3 days. Reheat gently on the stovetop or in the microwave, adding a splash of cream or milk to bring the sauce back to life. Freezing isn’t recommended, as cream-based sauces can separate and lose their smooth texture.
