Step-by-Step Beginner-Friendly Instructions

Boil the pasta. Bring a large pot of salted water to a rolling boil. Add the pasta and cook according to package directions until al dente, usually 9 to 11 minutes. Before draining, reserve 1/2 cup of pasta water. Drain the pasta and set it aside.
Season the shrimp. While the pasta cooks, pat the shrimp dry with paper towels. Place them in a small bowl and toss with 1 tablespoon olive oil, 1 tablespoon Cajun seasoning, smoked paprika, salt, and black pepper. The shrimp should be evenly coated and lightly red-orange in color. 😊
Sear the shrimp. Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the shrimp in a single layer and cook for 1 to 2 minutes per side, until pink, curled, and lightly golden. Transfer the shrimp to a plate. Do not overcook; they will finish warming in the sauce later.
Cook the vegetables. Reduce the heat to medium. Add the diced onion and sliced red bell pepper to the same skillet. Cook for 4 to 5 minutes, stirring often, until the onion looks soft and the pepper is tender-crisp.
Add garlic and seasoning. Stir in the minced garlic, remaining 1 tablespoon Cajun seasoning, and optional red pepper flakes. Cook for 30 to 60 seconds until fragrant. The garlic should smell warm and savory, not browned.
Make the creamy sauce. Pour in the chicken broth and scrape the bottom of the skillet with a wooden spoon to lift up the flavorful browned bits. Add the heavy cream and butter, then stir well. Simmer gently for 3 to 4 minutes until the sauce is slightly thick and glossy. 😋
Add the cheese. Lower the heat to medium-low. Stir in the Parmesan cheese a little at a time until melted and smooth. If the sauce becomes too thick, add reserved pasta water 1 tablespoon at a time until it loosens.
Combine everything. Add the drained pasta and cooked shrimp back to the skillet. Toss with tongs for 1 to 2 minutes until every strand or piece of pasta is coated in sauce and the shrimp is heated through.
Finish and serve. Sprinkle with chopped parsley and taste for seasoning. Serve warm while the sauce is creamy and silky. For extra brightness, add a squeeze of fresh lemon juice if desired. 🍤

💡 Pro Tips

Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop with a splash of broth or cream to revive the sauce.
Substitutions: Swap shrimp for sliced chicken breast or chicken thighs if you prefer a different protein. Cook chicken fully before adding it back to the sauce.
Texture tip: Cook the pasta just until al dente so it holds up when tossed in the creamy Cajun sauce.
Spice control: Use a mild Cajun seasoning for a family-friendly version, or add extra crushed red pepper flakes for more heat.

Variations

Chicken Cajun Pasta: Replace shrimp with 1 pound of thinly sliced chicken breast. Sear until golden and cooked through, then add it back at the end.
Veggie-Loaded Version: Add sliced mushrooms, spinach, or zucchini for extra color and nutrients.
Lighter Cream Sauce: Use half-and-half instead of heavy cream for a lighter sauce. Simmer gently to prevent separation.
Extra Cheesy Pasta: Add an additional 1/4 cup Parmesan for a richer, more savory finish.

FAQ

Can I use frozen shrimp?

Yes. Thaw frozen shrimp completely in the refrigerator or under cold running water, then pat them very dry before seasoning. Dry shrimp sear better and keep the sauce from becoming watery.

What pasta works best for Creamy Cajun Shrimp Pasta?

Fettuccine, linguine, penne, and rigatoni all work well. Long pasta gives a classic creamy finish, while short pasta catches the sauce in every bite.

How do I keep the sauce creamy?

Use medium to medium-low heat after adding the cream and cheese. Avoid boiling the sauce hard, and add reserved pasta water a little at a time if it thickens too much.

Is Cajun seasoning very spicy?

It depends on the brand. Some blends are mild and smoky, while others are hotter. Start with the amount listed, then adjust after tasting the sauce.

Can I make this ahead of time?

This pasta tastes best fresh, but you can prep the vegetables and season the shrimp a few hours ahead. Cook the pasta and sauce just before serving for the best creamy texture.
