Creamy Cajun Shrimp Pasta

Creamy Cajun Shrimp Pasta

Make creamy Cajun shrimp pasta with peppers, garlic, and Parmesan sauce. Includes clear cooking stages, seasoning notes, and tips for tender shrimp.

Creamy Cajun shrimp pasta combines seasoned shrimp, red bell pepper, onion, and noodles in a Parmesan cream sauce. Paprika and Cajun seasoning give the shrimp a savory coating, while garlic, Italian seasoning, and red pepper flakes flavor the sauce. Parsley finishes the dish just before serving.

The recipe takes about 30 minutes and uses a pasta pot plus a large skillet. Reserve the pasta water before draining; it helps adjust the sauce during the final toss. Jump to the recipe card for measurements and the complete cooking method.

Why This Cajun Shrimp Pasta Works

The shrimp cook separately before the vegetables and sauce. Removing them gives the pepper and onion time to soften without leaving the seafood over heat. Heavy cream and Parmesan then combine with the flavors already in the skillet, producing a sauce that coats the pasta.

Reserved pasta water gives you control at the end. The noodles and cheese can make the mixture feel thicker as you toss, so adding water gradually is more useful than committing to the entire amount at once. The sauce should coat the strands without becoming stiff or watery.

Creamy Cajun Shrimp Pasta Ingredients

  • 450 g spaghetti or linguine
  • 450 g shrimp, peeled and deveined
  • 2 tbsp butter
  • 1 tbsp olive oil
  • 3 cloves garlic, minced
  • 1 small red bell pepper, diced
  • ½ small onion, diced
  • 1 cup heavy cream
  • ½ cup grated Parmesan cheese
  • 1 tsp Cajun seasoning
  • ½ tsp paprika
  • ½ tsp Italian seasoning
  • Salt and black pepper, to taste
  • ¼ tsp red pepper flakes
  • 2 tbsp fresh parsley, chopped
  • ½ cup reserved pasta water

Ingredient Notes

The recipe uses equal listed weights of pasta and shrimp. Choose spaghetti or linguine as specified and follow the pasta package directions. If using frozen shrimp, thaw according to the packaging, drain, and pat dry before seasoning so excess moisture does not enter the skillet.

Cajun seasoning blends differ in heat and salt. Start with the measured amount and taste the finished sauce before adding extra salt. Parmesan contributes seasoning too. For less heat, reduce or omit the red pepper flakes and use a milder Cajun blend.

How to Make Creamy Cajun Shrimp Pasta

1. Cook the Pasta

Cook the spaghetti or linguine in salted water according to its package directions. Reserve ½ cup of pasta water before draining. Have the cooked noodles ready for the sauce rather than leaving them in boiling water while you finish the shrimp.

2. Season and Sear the Shrimp

Season the shrimp with Cajun seasoning, paprika, salt, and pepper. Heat the olive oil and butter in a large skillet over medium-high heat. Cook the shrimp for about 2–3 minutes per side, adjusting for their size and checking that they are cooked through. Remove them from the skillet.

3. Soften the Vegetables

Add the diced onion and red bell pepper to the same skillet. Cook for 3–4 minutes, until softened. Stir in the garlic and red pepper flakes and cook for about 30 seconds. Lower the heat if the garlic begins coloring too quickly.

4. Make the Parmesan Cream Sauce

Pour in the heavy cream and add the Italian seasoning. Simmer gently for 2–3 minutes. Stir in the Parmesan until the sauce is smooth, keeping the heat controlled instead of boiling aggressively. Have the pasta nearby so it can go into the sauce as soon as it is ready.

5. Toss, Warm, and Serve

Add the pasta and toss until coated. Use the reserved pasta water a little at a time to reach the consistency you prefer. Return the shrimp and warm gently for another 1–2 minutes. Finish with parsley and serve hot, distributing the shrimp and vegetables across the plates.

Tips for a Creamy Sauce Without Overcooked Shrimp

Prepare the vegetables and grate the cheese before cooking. The short garlic stage is easier to manage when the cream and seasonings are already measured. A wide skillet also gives you room to lift the noodles through the sauce without pushing ingredients over the rim.

Keep the cooked shrimp out of the pan while the vegetables soften and the sauce simmers. They only return for the final warming. If the sauce needs adjustment, make it before adding the seafood back rather than keeping the shrimp hot while deciding on the consistency.

Add the pasta water gradually and toss between additions. You may not need the full reserved amount. The pasta continues to absorb liquid as it sits, so aim to serve once everything is coated and hot instead of leaving the finished dish on the burner.

What to Serve with Cajun Shrimp Pasta

A simple salad with a light dressing balances the rich cream sauce. Garlic bread is optional for catching extra sauce, while steamed vegetables provide another straightforward side. Extra pepper or Parmesan can be offered at the table without increasing the seasoning across the entire skillet.

For a Cajun pasta with a different cheese combination, try Cajun garlic butter shrimp with cheesy spaghetti. If you prefer a broth-based pan sauce instead of cream, see Cajun shrimp and sausage noodles. Both offer another way to plan a shrimp pasta dinner.

Frequently Asked Questions

Can I use a different pasta shape?

Yes, fettuccine or penne would both work well in place of spaghetti or linguine.

Can I use frozen shrimp?

Yes, just thaw completely and pat dry before cooking so they sear properly instead of releasing excess water.

Can I lighten up the sauce?

Half-and-half can be used in place of heavy cream, though the sauce will be a bit thinner and less rich.

Reserve 1/2 cup of pasta water before draining so you can loosen the sauce as needed.
Season the shrimp evenly before searing for the best Cajun flavor.
Cook the shrimp only until pink and lightly browned, then remove them to prevent overcooking.
Sauté the onion and bell pepper until softened before adding the garlic.
Simmer the cream gently and stir in the Parmesan until smooth.
Add the reserved pasta water gradually until the sauce reaches your preferred consistency.
Return the shrimp at the end and heat only until warmed through.
