This 20-minute creamy Cajun shrimp pasta combines juicy, golden shrimp with tender pasta and a silky garlic-Parmesan cream sauce. Cajun seasoning and chili flakes bring a warm kick, while finely chopped bell pepper adds color, sweetness, and a little texture to every forkful.
This creamy Cajun shrimp pasta is a fast seafood dinner with restaurant-style flavor, and the sauce comes together in one skillet while the pasta cooks. Reserve a little pasta water before draining—it is the easiest way to loosen the sauce without making it watery.

Ingredients Needed
- 225 g (½ lb) large shrimp, peeled and deveined
- 1 tablespoon Cajun seasoning
- 1 tablespoon olive oil
- 1 tablespoon butter
- 2 tablespoons Parmesan cheese
- 1 teaspoon tomato paste
- 1 bell pepper, finely chopped

- 250 ml (1 cup) heavy cream
- Salt and black pepper, to taste
- Chili flakes, to taste
- Dried basil or oregano, optional
- 225 g (8 oz) pasta
Ingredient Notes and Substitutions
Shrimp: Large peeled and deveined shrimp are quick to cook and easy to toss through the pasta. If using frozen shrimp, thaw them safely and pat them dry before seasoning so they sear instead of steaming.
Cajun seasoning: Blends vary in salt and heat. Taste the sauce before adding extra salt or chili flakes, especially if your Cajun seasoning already contains both.
Bell pepper: Finely chopped pepper softens quickly and distributes sweet, colorful bites through the sauce. Any color of bell pepper works without changing the method.
Parmesan: Finely grated Parmesan melts more evenly than thick shreds. Stir it in after the pasta and sauce are combined so it coats the noodles smoothly.
Pasta: Long pasta such as fettuccine, linguine, or spaghetti holds the creamy sauce well. The original recipe did not specify an amount; this draft uses 225 g (8 oz), based on comparable shrimp-and-cream pasta recipes.
How to Make Creamy Cajun Shrimp Pasta
1. Cook the pasta
Bring a pot of salted water to a boil and cook the pasta until al dente. Scoop out a little pasta water, then drain the pasta.
2. Season and sear the shrimp
Toss the shrimp with the Cajun seasoning until evenly coated. Heat the olive oil or butter in a large skillet over medium-high heat. Add the shrimp in a single layer and sear for 1–2 minutes per side, until pink and just cooked through. Transfer them to a plate.
3. Sauté the bell pepper
Reduce the heat to medium. Add olive oil as needed, then cook the finely chopped bell pepper for 3–4 minutes, stirring occasionally, until it begins to soften.
4. Build the sauce
Stir in the minced garlic and tomato paste and cook for about 30 seconds. Pour in the heavy cream, then season with salt, black pepper, and chili flakes. Keep the sauce at a gentle simmer for 2–3 minutes, until slightly thickened.
5. Toss everything together
Add the drained pasta, seared shrimp, and Parmesan to the skillet. Toss until the pasta and shrimp are evenly coated in the creamy Cajun sauce. Add dried basil or oregano if using. If the sauce is thicker than you like, loosen it with a small splash of the reserved pasta water.
6. Serve immediately
Remove the skillet from the heat and serve while the sauce is hot, glossy, and creamy.
How to Keep the Shrimp Tender
Dry shrimp brown better, so blot them well before adding the Cajun seasoning. Cook them in a hot skillet only until both sides are pink and the flesh is firm, pearly, and opaque, then remove them promptly. The FDA’s seafood safety guidance identifies firm, pearly, opaque flesh as a visual cue for cooked shrimp.
Returning the shrimp at the very end warms them through without exposing them to several extra minutes of simmering. That brief finish is what keeps them juicy rather than rubbery.
How to Keep the Cajun Cream Sauce Smooth
Keep the cream at a gentle simmer rather than a hard boil. High heat can reduce the sauce too quickly and make the dairy look grainy. Add the finely grated Parmesan with the pasta, toss continuously, and use reserved pasta water a tablespoon at a time if the sauce needs loosening.
Tips for the Best Creamy Cajun Shrimp Pasta
- Pat the shrimp dry so the Cajun coating sears instead of releasing excess moisture.
- Use a skillet large enough to keep the shrimp in a single layer for even browning.
- Cook the pasta only to al dente because it will soften slightly when tossed in the hot sauce.
- Sauté the tomato paste briefly with the garlic to deepen its flavor before adding the cream.
- Taste before adding extra salt; Cajun seasoning and Parmesan may already contribute plenty.
- Serve the creamy Cajun shrimp pasta immediately, since the sauce naturally thickens as it cools.
What to Serve with Cajun Shrimp Pasta
A crisp green salad, roasted vegetables, or warm crusty bread balances the rich sauce. For another creamy seafood dinner, try creamy garlic shrimp fettuccine Alfredo or Marry Me shrimp pasta. If you want the same garlicky shrimp-and-Parmesan flavors without pasta, creamy garlic Parmesan shrimp is a closely related option.
Storage and Reheating
Refrigerate creamy Cajun shrimp pasta leftovers promptly in a covered container. The USDA recommends refrigerating cooked food within two hours and using most refrigerated leftovers within three to four days; see its leftovers and food safety guidance.
Reheat the pasta gently in a covered skillet over low heat, stirring occasionally until hot. Add a small splash of water or cream if needed to loosen the sauce. Avoid high heat, which can split the sauce and overcook the shrimp.
Frequently Asked Questions
Can I use frozen shrimp?
Yes. Thaw frozen shrimp in the refrigerator, or follow the FDA’s safe cold-water thawing guidance, then drain and pat them completely dry before seasoning.
Which pasta shape works best?
Fettuccine, linguine, and spaghetti all hold the creamy sauce well. A short ridged pasta can also work, but the finished texture will be different from the long-pasta version shown.
Is Cajun shrimp pasta very spicy?
The heat depends on your Cajun seasoning and how many chili flakes you add. Start lightly with the chili flakes, taste the finished sauce, and add more only if needed.
Why did my cream sauce become too thick?
The sauce may have simmered too long or cooled before serving. Toss in reserved pasta water one tablespoon at a time until it becomes silky again.
Can I make this recipe ahead?
Creamy shrimp pasta is best served right after cooking. You can chop the bell pepper and garlic and measure the other ingredients ahead, but cook the shrimp, sauce, and pasta just before serving for the best texture.
How do I know when the shrimp are done?
The shrimp should be pink outside and firm, pearly, and opaque inside. Remove them from the skillet as soon as they reach that stage, because they will warm again in the sauce.
