Shrimp and crab are staples of coastal cuisine—simple, fresh, and always crowd-pleasing. Pair them with pasta, and you have a dish that captures the essence of both southern and Italian comfort food traditions.

Ingredients You’ll Need
The beauty of this recipe is that it uses easy-to-find ingredients that, when combined, create extraordinary depth of flavor.
For the Pasta Base:
- 12 ounces fettuccine or linguine – Long pasta types hold creamy sauces beautifully.
- 1 tablespoon olive oil – Prevents the pasta from sticking after cooking.
- Salt (for boiling water) – Enhances the pasta’s flavor from within.
For the Seafood:
- 1 pound medium shrimp, peeled and deveined – Fresh or frozen, just make sure they’re cleaned well.
- 1 cup lump crab meat – Sweet, tender, and the star of the show. Pasteurized crab works perfectly.
For the Creamy Cajun Sauce:
- 2 tablespoons unsalted butter – Adds richness and silky texture.
- 4 cloves garlic, minced – Builds the aromatic base.
- 1 cup heavy cream – The foundation of your luscious sauce.
- 1 cup low-sodium chicken broth – Balances out the richness of the cream.
- 2 tablespoons Cajun seasoning – Use your favorite brand or make your own blend for control over spice.
- 1 teaspoon paprika – Deepens the color and enhances smokiness.
- Salt and black pepper, to taste – Adjust according to your preference.
- Juice of half a lemon – Brightens the dish and cuts through the creaminess.
- Fresh parsley, chopped – Adds a pop of freshness before serving.
Step-by-Step Instructions
Let’s cook this masterpiece together.
Step 1: Boil the Pasta
Start by bringing a large pot of salted water to a rolling boil. Add the pasta and cook it until al dente, following package directions. Once cooked, drain the pasta, drizzle with olive oil to prevent sticking, and set aside.
Step 2: Sauté Garlic and Shrimp
In a large skillet, melt butter over medium heat. Add minced garlic and sauté until fragrant—about one minute.
Now, add the shrimp. Cook them for 2–3 minutes per side until pink and opaque. Remove the shrimp from the pan and set them aside.
Step 3: Add the Crab Meat
In the same pan, gently fold in the crab meat. Let it warm for about one minute while absorbing the garlic-butter flavor. Don’t overcook—it’s delicate.
Step 4: Build the Cajun Sauce
Pour in the heavy cream and chicken broth. Sprinkle in the Cajun seasoning and paprika. Stir continuously, letting the sauce simmer gently until it thickens slightly. The aroma at this stage is pure magic—creamy, smoky, and irresistible.
Step 5: Combine Everything
Return the shrimp to the skillet, then add your cooked pasta. Toss everything together until each strand is luxuriously coated in sauce. Add a squeeze of lemon juice, toss again, and sprinkle fresh parsley on top.
Step 6: Serve Hot
Plate generously, making sure each serving has a good mix of shrimp, crab, and sauce. Garnish with extra parsley or a pinch of Cajun spice for color.
Chef’s Tips for Perfect Results
- Don’t overcook shrimp: They only need a few minutes—once pink, they’re done.
- Simmer, don’t boil: The sauce thickens best over gentle heat; boiling may cause it to separate.
- Use fresh Cajun seasoning: Homemade blends often taste brighter and more balanced.
- Add cheese sparingly: While Parmesan can enhance flavor, too much can overpower the Cajun notes.
- Balance the salt: Remember that both Cajun seasoning and broth contain sodium—taste as you go.
Cajun Flavor Customization
Want it hotter? Add crushed red pepper flakes or a dash of cayenne.
Prefer it milder? Use half the Cajun seasoning and balance with smoked paprika.
Want to go veggie-forward? Add sautéed bell peppers, spinach, or cherry tomatoes for a vibrant twist.
What to Serve With Shrimp & Crab Pasta
This pasta stands beautifully on its own, but pairing it with a few sides takes it over the top:
- Garlic bread for soaking up extra sauce.
- A simple Caesar salad for a crisp, fresh contrast.
- A chilled glass of white wine (like Sauvignon Blanc or Pinot Grigio) that complements the seafood’s sweetness.
Storage and Reheating
Leftovers? Lucky you.
- Storage: Transfer to an airtight container and refrigerate for up to three days.
- Reheat: Warm gently on the stove over low heat, adding a splash of broth or cream to restore smoothness.
- Freezing: While not ideal due to cream separation, you can freeze it in portions for up to one month. Thaw in the fridge overnight before reheating.
Common Mistakes to Avoid
- Overcooking seafood: Shrimp and crab cook quickly—timing is everything.
- Using too much Cajun spice: Start small and adjust; you can always add more later.
- Skipping lemon juice: The acidity keeps the sauce balanced and lively.
- Boiling the sauce: High heat breaks the cream; always simmer gently.
- Undercooked pasta: The sauce clings better to al dente pasta.
