Key Ingredients for Creamy Cajun Shrimp and Crab Pasta

• 12 oz pasta (fettuccine, linguine, or penne)

• 1 lb shrimp, peeled and deveined

• 8 oz lump crab meat, picked over for shells

• 2 tbsp butter

• 1 tbsp olive oil

• 3 cloves garlic, minced

• 1½ cups heavy cream

• ½ cup chicken or seafood broth

• 1 cup grated Parmesan cheese

• 1½ tbsp Cajun seasoning (adjust to taste)

• ½ tsp smoked paprika

• Salt and black pepper, to taste

• ¼ tsp red pepper flakes (optional)

• Fresh parsley, chopped (for garnish)

• Lemon wedges, for serving

Step-by-Step Instructions

1. Cook the Pasta
   Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Reserve ½ cup of pasta water, then drain and set aside.

2. Season the Shrimp
   Pat the shrimp dry with paper towels. Toss them with 1 tablespoon Cajun seasoning, paprika, salt, and pepper to ensure even coating.

3. Sauté the Shrimp
   Heat olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Add shrimp in a single layer and cook for 2–3 minutes per side until pink and opaque. Remove shrimp and set aside.

4. Make the Sauce Base
   In the same skillet, melt the remaining butter. Add garlic and sauté for 30 seconds until fragrant. Pour in the broth and scrape up any browned bits for extra flavor.

5. Create the Creamy Cajun Sauce
   Lower the heat and add heavy cream, remaining Cajun seasoning, and red pepper flakes. Simmer gently for 3–4 minutes until slightly thickened.

6. Add Cheese and Seafood
   Stir in Parmesan cheese until smooth. Gently fold in crab meat and cooked shrimp, being careful not to break up the crab too much.

7. Combine with Pasta
   Add cooked pasta to the sauce and toss until fully coated. Use reserved pasta water to loosen the sauce if needed.

8. Finish and Serve
   Taste and adjust seasoning. Garnish with fresh parsley and serve hot with lemon wedges.

What to Serve Creamy Cajun Shrimp and Crab Pasta With

• Garlic bread or cheesy breadsticks for soaking up extra sauce

• Crisp Caesar salad to balance the richness

• Steamed asparagus or roasted broccoli for freshness

• A chilled glass of white wine like Sauvignon Blanc or Pinot Grigio

• Lemon iced tea for a non-alcoholic option

These sides complement the creamy, spicy flavors without overpowering the dish.

Top Tips for Perfecting Creamy Cajun Shrimp and Crab Pasta

• Don’t overcook the shrimp—they turn rubbery fast. Remove them as soon as they’re pink.

• Use fresh or high-quality frozen seafood for best flavor.

• Adjust Cajun seasoning to your spice tolerance; brands vary in heat.

• Substitute half-and-half for a lighter sauce, but expect a thinner texture.

• Avoid boiling the sauce once cream is added to prevent curdling.

• Add a splash of lemon juice at the end to brighten the flavors.

These tips help ensure your pasta turns out creamy, flavorful, and perfectly balanced every time.

Storing and Reheating Tips

Store leftover Creamy Cajun Shrimp and Crab Pasta in an airtight container in the refrigerator for up to 3 days. Seafood dishes are best enjoyed fresh, but proper storage keeps them safe and tasty.

To reheat, warm gently in a skillet over low heat, adding a splash of cream or broth to restore the sauce’s creamy texture. Avoid microwaving on high, as it can overcook the shrimp and dry out the crab.

Freezing is not recommended due to the cream sauce, which can separate when thawed. If you do freeze it, reheat slowly and stir well for best results.

If you’re craving a bold, comforting meal that feels indulgent but is easy to make, this Creamy Cajun Shrimp and Crab Pasta deserves a spot on your dinner table. Happy cooking! 🍝✨
