👨‍🍳 How to Make Easy Cajun Shrimp Pasta

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add the pasta and cook until al dente, usually about 8–10 minutes. Reserve 1/2 cup of pasta water, then drain and set aside.

Step 2: Season and Sauté the Shrimp

Pat shrimp dry with paper towels. In a bowl, toss them with Cajun seasoning, salt, and pepper.

Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Add shrimp in a single layer and cook for 1–2 minutes per side until pink and opaque. Remove shrimp and set aside.

Step 3: Make the Creamy Cajun Sauce

In the same skillet, reduce heat to medium. Add 2 tablespoons butter and minced garlic. Sauté for about 1 minute until fragrant.

Stir in heavy cream and chicken broth, whisking until combined. Bring to a gentle simmer, then gradually add Parmesan cheese, stirring constantly to melt and thicken the sauce.

Season with additional Cajun seasoning, paprika, cayenne, salt, and pepper to taste. Simmer for 3–5 minutes until sauce coats the back of a spoon.

Step 4: Toss Everything Together

Add the cooked pasta to the skillet and toss to coat evenly with the sauce. Add a bit of reserved pasta water if the sauce needs loosening.

Return shrimp to the pan and stir gently to combine and warm through.

Step 5: Garnish and Serve

Top with chopped parsley, freshly grated Parmesan, and a squeeze of lemon juice if desired. Serve hot with garlic bread or a fresh salad.


🔄 Variations

  • Cajun Chicken Pasta – Swap shrimp with grilled chicken breast slices.
  • Cajun Seafood Pasta – Add scallops, mussels, or crab for a seafood medley.
  • Vegetarian Option – Use mushrooms, roasted red peppers, or zucchini.
  • Extra Creamy Version – Add 2 oz cream cheese for an ultra-rich sauce.
  • Low-Carb/Keto – Serve over zucchini noodles or cauliflower rice.

🍳 Cooking Note

Avoid overcooking shrimp—they cook quickly and can become rubbery. They should turn pink and form a slight “C” shape when done.


🍽️ Serving Suggestions

  • Serve with warm garlic bread or cheesy toast
  • Pair with a crisp Caesar or garden salad
  • Add a side of roasted broccoli or asparagus
  • A glass of white wine (Chardonnay or Pinot Grigio) complements the spice
  • Finish with a dash of red pepper flakes or lemon zest for a fresh finish

💡 Helpful Tips

  • Use raw, not pre-cooked shrimp for best texture.
  • Grate Parmesan fresh from the block—it melts better and tastes richer.
  • Taste the sauce before serving and adjust seasoning as needed.
  • Don’t rinse the pasta—residual starch helps the sauce stick.
  • To prevent curdling, keep the sauce at a low simmer—not a boil.

⭐ Tips for the Best Cajun Shrimp Pasta

  • Use high-quality Cajun seasoning: Look for one with bold paprika, garlic, thyme, and just enough kick.
  • Layer your flavors: Season shrimp separately, then enhance the sauce with more Cajun spice.
  • Cook pasta just al dente: It will finish cooking in the sauce, soaking up the flavor.
  • Add acid at the end: A splash of lemon juice or vinegar brightens the creamy dish.
  • For a restaurant-quality look: Garnish with herbs, extra Parmesan, and a drizzle of olive oil.

❓ FAQs

Q: Is Cajun Shrimp Pasta spicy?
Yes, but the heat level depends on your Cajun seasoning and any added cayenne. Adjust spice to your taste.

Q: Can I make this ahead?
It’s best served fresh, but you can cook the shrimp and sauce ahead. Reheat gently and cook pasta just before serving.

Q: What pasta works best?
Fettuccine or linguine are ideal, but penne, rotini, or spaghetti work well too.

Q: Can I use milk instead of heavy cream?
You can, but the sauce will be lighter and less creamy. Whole milk is the best alternative if needed.

Q: Can I freeze Cajun Shrimp Pasta?
It’s not ideal—cream sauces may separate. If freezing, freeze just the shrimp and sauce, and cook fresh pasta when ready to eat.
