There are a lot of Cajun shrimp pasta recipes out there, but a few things make this version stand out.
Before we dive in, a quick word on the two ingredients that make or break this dish.
Cajun Seasoning: The spice blend is the heart of the recipe. A good Cajun seasoning should have depth, smokiness, and warmth without being aggressively salty. If yours is very salty, use a little less and season to taste at the end. You can also make your own in minutes with paprika, garlic powder, onion powder, oregano, thyme, cayenne, and black pepper.
Shrimp: Go for large or extra-large shrimp (21/25 count per pound) for the best bite. Frozen shrimp that have been thawed work just as well as fresh, and they are often a better value. The most important thing is to pat them completely dry before seasoning so they sear rather than steam.
Using quality tools and pantry staples genuinely elevates this dish from good to great. A heavy 12-inch skillet with even heat distribution is the single most important piece of equipment here.
This recipe is forgiving and flexible, but a few tips will help you get it right the first time.
Chef's Tip: Do not overcrowd the shrimp in the pan. Cook them in a single layer and resist the urge to move them around. That direct contact with the hot pan is what creates the golden, caramelized crust that makes them so irresistible.
On the pasta: Cook it just to al dente since it will finish cooking briefly in the warm sauce. Always save some pasta water before you drain. The starchy water is liquid gold for adjusting sauce consistency without making it watery.
On the heat level: The recipe as written is medium-spicy. If you are cooking for guests with different heat tolerances, start with 1.5 tablespoons of Cajun seasoning and hold the red pepper flakes. You can always add heat at the table.

This Cajun Shrimp Pasta with Spicy Cream Sauce is bold, creamy, and ready in 30 minutes. Perfectly seasoned shrimp tossed with penne in a rich, smoky cream sauce that tastes like a restaurant splurge at home.
Bring a large pot of salted water to a boil. Cook the penne pasta according to package directions until al dente. Reserve 0.5 cup of pasta water before draining, then drain and set aside.
Pat the shrimp dry with paper towels and toss them with 1 tablespoon of the Cajun seasoning until evenly coated.
Heat 1 tablespoon of olive oil in a large skillet or sauté pan over medium-high heat. Add the shrimp in a single layer and cook for 1 to 2 minutes per side, just until pink and slightly charred. Transfer to a plate and set aside.
In the same skillet, melt the butter with the remaining tablespoon of olive oil over medium heat. Add the diced onion and red bell pepper and cook for 3 to 4 minutes until softened.
Add the minced garlic and cook for 30 seconds, stirring constantly, until fragrant.
Pour in the chicken broth and stir to deglaze the pan, scraping up any browned bits from the bottom.
Reduce heat to medium-low and stir in the heavy cream, drained diced tomatoes, remaining 1 tablespoon of Cajun seasoning, smoked paprika, and red pepper flakes if using. Simmer for 4 to 5 minutes, stirring occasionally, until the sauce thickens slightly.
Stir in the grated Parmesan cheese until melted and smooth. Taste the sauce and adjust salt as needed.
Add the cooked pasta to the skillet and toss to coat, adding a splash of the reserved pasta water if the sauce needs loosening.
Return the cooked shrimp to the pan and gently fold them into the pasta. Cook for 1 minute just to warm everything through.
Serve immediately, garnished with fresh parsley and extra Parmesan cheese.
This pasta is best served immediately, straight from the pan while the sauce is glossy and the shrimp are still tender. Pile it into warm bowls and finish with a generous shower of freshly grated Parmesan and a scatter of chopped parsley.
What to serve alongside it:
Storing leftovers: Transfer cooled pasta to an airtight container and refrigerate for up to 3 days. Reheat gently in a skillet with a small splash of cream or broth. Avoid the microwave if possible since it tends to make the shrimp rubbery.
