Ingredients

Here is everything you need:

For the Pasta

• 12 ounces (340 g) fettuccine or linguine pasta
• 1 tablespoon salt (for boiling water)

For the Seafood

• 1 pound (450 g) large shrimp, peeled and deveined
• 8 ounces (225 g) lump crab meat, cooked
• 1 tablespoon olive oil
• 1 tablespoon butter
• 1 teaspoon Cajun seasoning (for shrimp)
• ½ teaspoon salt
• ½ teaspoon black pepper

For the Creamy Cajun Sauce

• 2 tablespoons butter
• 3 cloves garlic, minced
• 1 small onion, finely chopped
• 1 red bell pepper, thinly sliced
• 1½ cups heavy cream
• 1 cup whole milk
• 1 cup grated Parmesan cheese
• 1½ teaspoons Cajun seasoning (adjust to taste)
• ½ teaspoon smoked paprika
• ½ teaspoon dried thyme
• Salt and black pepper to taste
• 1 tablespoon fresh parsley, chopped (for garnish)

Optional:

• A squeeze of fresh lemon juice
• Red pepper flakes for extra heat

Step-by-Step Instructions

Step 1: Cook the Pasta

Bring a large pot of water to a boil. Add 1 tablespoon of salt. This helps flavor the pasta.

Add the pasta and cook according to the package instructions until al dente (firm but cooked). Stir once or twice so it does not stick together.

Before draining, save ½ cup of the pasta water. Then drain the pasta and set it aside.

Tip: Do not rinse the pasta. The starch helps the sauce stick better.

Step 2: Season and Cook the Shrimp

Pat the shrimp dry with paper towels. This helps them cook nicely.

Season them with 1 teaspoon Cajun seasoning, salt, and black pepper.

Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium heat. Once hot, add the shrimp in a single layer.

Cook for about 2–3 minutes on each side. They will turn pink and slightly golden. Do not overcook them or they will become rubbery.

Remove the shrimp from the pan and set aside.

Step 3: Start the Cajun Cream Sauce

In the same skillet, add 2 tablespoons butter. Let it melt.

Add the chopped onion and sliced red bell pepper. Cook for 3–4 minutes until soft. Stir often.

Add the minced garlic and cook for 30 seconds. Be careful not to burn it.

Step 4: Make the Creamy Base

Pour in the heavy cream and milk. Stir well.

Add:

• 1½ teaspoons Cajun seasoning
• Smoked paprika
• Dried thyme

Bring the sauce to a gentle simmer. Do not let it boil too hard. Cook for about 5–7 minutes until it thickens slightly.

If the sauce becomes too thick, add a little of the reserved pasta water. Stir gently.

Step 5: Add the Cheese

Lower the heat. Slowly add the grated Parmesan cheese while stirring.

Keep stirring until the cheese melts and the sauce becomes smooth and creamy.

Taste the sauce. Add more salt, pepper, or Cajun seasoning if needed.

Step 6: Add the Seafood

Gently add the cooked shrimp back into the pan.

Carefully fold in the crab meat. Stir softly so you do not break the crab too much.

Let everything cook together for 2–3 minutes. This helps the flavors blend.

If you like, add a small squeeze of lemon juice to brighten the flavor.

Step 7: Combine with Pasta

Add the cooked pasta to the skillet.

Toss everything together gently until the pasta is fully coated in the creamy Cajun sauce.

If needed, add a splash of pasta water to loosen the sauce.

Turn off the heat and sprinkle fresh parsley on top.

Your Shrimp and Crab Pasta with Creamy Cajun Sauce is ready to serve!

Tips & Variations
