Ingredients You’ll Need
Each ingredient in Shrimp & Crab Pasta with Creamy Cajun Sauce brings a little bit of magic to the table. Nothing complicated here—just fresh, flavorful staples that work together to create an irresistible pasta you’ll want to make again and again.
- 12 oz linguine or fettuccine pasta: The foundation of the dish, soaking up all those creamy, spicy flavors beautifully.
- 1 tablespoon olive oil: Helps the butter melt smoothly and prevents sticking.
- 1 tablespoon butter: Adds richness and a soft, velvety base for the sauce.
- 1 pound large shrimp (peeled and deveined): Plump, juicy shrimp are the star protein—choose fresh if possible!
- 8 oz lump crab meat: Sweet, delicate crab amplifies the luxurious feel and pairs wonderfully with the shrimp.
- 1 small onion (finely chopped): Provides aromatic depth and gentle sweetness that balances the Cajun spices.
- 3 cloves garlic (minced): Fresh garlic brings a bold, savory edge to the sauce.
- 1 ½ cups heavy cream: The secret to that silky, indulgent texture—don’t skimp here.
- ½ cup chicken broth: Adds flavor and helps lighten the sauce without sacrificing creaminess.
- ½ cup grated Parmesan cheese: Melts smoothly into the sauce, adding salty, nutty complexity.
- 2 teaspoons Cajun seasoning (plus more to taste): The essential spice blend—adjust the heat to your liking.
- ½ teaspoon smoked paprika: Offers subtle smoky, earthy notes that deepen the flavor profile.
- Salt and black pepper to taste: Rounds out and sharpens all the flavors perfectly.

- Lemon wedges for serving (optional): A final squeeze of lemon wakes up all the seafood flavors beautifully.
How to Make Shrimp & Crab Pasta with Creamy Cajun Sauce
Step 1: Boil the Pasta
Bring a generous pot of salted water to a boil and cook your linguine or fettuccine until it’s perfectly al dente, according to package directions. Just before you drain it, remember to scoop out half a cup of that magic pasta water—it’s key for adjusting the sauce later. Set the drained pasta and reserved water aside.
Step 2: Sauté the Shrimp
Turn to your largest skillet and melt the olive oil and butter over medium heat. Add the shrimp in a single layer, sprinkle with a teaspoon of Cajun seasoning, and let them sizzle for 2 to 3 minutes on each side until just pink and cooked through. Transfer the shrimp to a plate, making sure you don’t overcook them—they’ll go back into the pan in a bit.
Step 3: Build the Cajun Cream Sauce
In that same pan (don’t wipe it out—the flavor’s just getting started!), sauté the chopped onion for a few minutes until soft and fragrant, then add the garlic and stir for another 30 seconds. Pour in the heavy cream and chicken broth, whisking to combine. Let the mixture come to a gentle simmer before sprinkling in the remaining Cajun seasoning, smoked paprika, and the Parmesan cheese. Keep stirring as the sauce transforms into creamy perfection, just thick enough to beautifully coat your pasta.
Step 4: Add the Seafood
Return the cooked shrimp to the skillet and gently add the lump crab meat. Let everything warm through for 2 to 3 minutes—a quick simmer is all you need so the seafood stays tender and succulent. Taste and adjust the seasoning with a pinch more salt, pepper, or Cajun spice if you’re feeling bold.
Step 5: Bring It All Together
Add the drained pasta right into the creamy sauce, tossing to coat every strand. If the sauce seems too thick, a splash or two of your reserved pasta water will loosen things up perfectly. Once everything is hot and glossy, you’re ready to serve up a plateful of Shrimp & Crab Pasta with Creamy Cajun Sauce that’ll have everyone at the table leaning in for seconds.
How to Serve Shrimp & Crab Pasta with Creamy Cajun Sauce
Garnishes
Finish your pasta with a sprinkle of fresh parsley for color and a burst of herbal freshness. If you like a touch of brightness, a wedge of lemon on the side is a terrific way to add acidity and highlight the delicate seafood flavor. A little extra Parmesan on top never hurts, either!
Side Dishes
This pasta is rich and satisfying, so balance it with something crisp and light—think a simple arugula salad tossed with lemon vinaigrette, or some tender roasted asparagus. Crusty bread is practically non-negotiable for mopping up those luscious drops of Cajun sauce.
Creative Ways to Present
For a special occasion, swirl the pasta into shallow bowls, pile the shrimp and crab right on top and drizzle any extra sauce over everything. Garnish with extra parsley and a sprinkle of smoked paprika. Or, serve as a stunning main at your next seafood dinner party, paired with a cold glass of white wine.
Make Ahead and Storage
Storing Leftovers
If you have leftovers of Shrimp & Crab Pasta with Creamy Cajun Sauce, transfer them to an airtight container and refrigerate within two hours of serving. The flavors will meld and deepen overnight, making for a delicious next-day lunch or dinner.
Freezing
While creamy pasta sauces don’t always freeze perfectly, you can freeze this dish if needed. Place cooled pasta in freezer-safe containers, and reheat gently to help preserve the texture of the seafood. Stir well after reheating for the best results.
Reheating
To reheat, place leftovers in a skillet over low heat, adding a splash of milk, cream, or chicken broth to restore creaminess. Stir gently until warmed through. Avoid high heat so the shrimp and crab remain tender, not overcooked.
FAQs
Can I use a different type Main Course
Absolutely! While linguine or fettuccine work best for clinging onto the creamy Cajun sauce, feel free to use spaghetti, penne, or whatever long or tubular pasta you have on hand.
Is there a substitute for heavy cream?
You can swap in half-and-half for a lighter version, or even use evaporated milk in a pinch—just know the sauce may not be quite as rich. For a dairy-free twist, try coconut cream and adjust the seasonings.
How spicy is Shrimp & Crab Pasta with Creamy Cajun Sauce?
It’s got a kick, but it’s entirely adaptable! Start with the suggested amount of Cajun seasoning, then add a little more or a dash of cayenne or hot sauce if you crave serious heat. Always taste and adjust before serving.
Can I make this recipe ahead of time?
You can prep the sauce, shrimp, and crab a day in advance. When ready to serve, cook fresh pasta, gently reheat the sauce and seafood, then toss everything together. This helps prevent overcooked seafood and mushy pasta.
What kind of crab meat should I buy?
Lump crab meat is dreamy for its sweet flavor and tender texture, but if it’s not available, backfin or claw meat will also work. Always pick through for shells before adding to your sauce.
