Ingredients & Substitutions

Shrimp

Large, plump shrimp work best for this dish, offering a slightly sweet contrast to the Cajun seasoning. Use fresh shrimp if possible, but frozen shrimp, properly thawed, will work just as well. If seafood isn’t your thing, swap the shrimp for grilled chicken or sausage for a different but equally delicious take.

Cajun Seasoning

A good Cajun seasoning blend is the backbone of this dish. It brings smoky, garlicky, and slightly spicy flavors that elevate the shrimp and sauce. While store-bought blends work fine, making your own mix lets you control the heat. A simple combination of paprika, garlic powder, onion powder, thyme, oregano, and a touch of cayenne does the trick.

Pasta

Short-cut pastas like penne, rigatoni, or rotini hold onto the creamy sauce beautifully, ensuring you get the perfect bite every time. But if long pasta is more your style, fettuccine or linguine will also work. Feel free to use whole wheat or gluten-free pasta for dietary preferences.

Cream & Cheese

Heavy cream creates the luscious, velvety texture that makes this sauce irresistible. If you prefer a lighter version, half-and-half works as well. Parmesan cheese adds a nutty, salty depth, but you can mix in mozzarella or even cream cheese for extra creaminess.

Garlic & Butter

A base of sautéed garlic in melted butter sets the foundation for the creamy sauce. The garlic infuses the sauce with its rich aroma, while the butter adds a layer of indulgence.

Vegetables (Optional but Recommended!)

Adding sautéed bell peppers, onions, or mushrooms brings extra depth to the dish. Spinach or sun-dried tomatoes can also be tossed in for a fresh twist.

How to Make Cajun Shrimp Pasta

1. Cook the Pasta

Boil a large pot of salted water and cook the pasta until al dente. Reserve about ½ cup of pasta water before draining, then set the pasta aside. This starchy water helps adjust the sauce’s consistency later.

2. Prepare the Shrimp

Toss the shrimp with Cajun seasoning until fully coated. Heat a large skillet over medium-high heat with a drizzle of olive oil. Add the shrimp in a single layer and cook for about 1-2 minutes per side until they turn pink and opaque. Remove them from the skillet and set aside.

3. Sauté the Garlic & Veggies

In the same skillet, lower the heat to medium and add butter. Once melted, toss in minced garlic and any veggies you’re using, like bell peppers or onions. Sauté until fragrant and slightly softened, about 2-3 minutes.

4. Make the Creamy Sauce

Pour in the heavy cream, stirring to combine with the sautéed ingredients. Let it simmer gently, then sprinkle in grated Parmesan cheese. Stir continuously until the cheese melts, and the sauce thickens into a silky consistency. If the sauce feels too thick, add a splash of the reserved pasta water to loosen it.

5. Combine Everything

Return the shrimp to the skillet along with the cooked pasta. Toss everything together so the pasta is well coated in the creamy, spicy sauce. Taste and adjust seasoning if needed—adding more Cajun seasoning for spice lovers or a pinch of salt for balance.

6. Serve & Garnish

Plate up the pasta while it’s hot, garnishing with freshly chopped parsley, extra Parmesan, or a pinch of red pepper flakes for extra heat. Serve with garlic bread or a side salad for a complete meal.

Toppings & Variations

Extra Cheesy Version

For those who believe there’s no such thing as too much cheese, stir in a handful of shredded cheddar or mozzarella before serving. The extra cheesiness makes the sauce even more indulgent.

Spicy Shrimp & Sausage Pasta

Adding sliced Andouille or smoked sausage alongside the shrimp enhances the smoky, savory flavors in the dish. Brown the sausage before cooking the shrimp for the best texture.

Veggie-Packed Twist

For a healthier take, toss in spinach, mushrooms, or even roasted cherry tomatoes for a pop of freshness and color.

Low-Carb Alternative

For a low-carb alternative, swap the pasta for zucchini noodles! Check out this recipe for Zucchini Noodles with Mushroom Sauce for a healthy, delicious twist.

How to Store & Reheat Cajun Shrimp Pasta

Storing Leftovers

Let the pasta cool completely before transferring it to an airtight container. Store it in the refrigerator for up to 3 days.

Reheating Instructions

For the best results, reheat the pasta in a skillet over medium-low heat with a splash of milk or broth to loosen the sauce. Microwave reheating works too but may slightly dry out the shrimp.

Freezing Cajun Shrimp Pasta

This pasta can be frozen, but keep in mind that the creamy sauce may separate slightly when thawed. For the best texture, freeze the sauce and shrimp separately from the pasta. Thaw overnight in the fridge before reheating.
