Ingredients You’ll Need

Gathering quality ingredients is your first step toward this fabulous fusion of creamy and spicy. Each element in this list plays a pivotal role, whether it’s enhancing texture, infusing that signature Cajun kick, or contributing freshness to brighten up the dish.

1 pound shrimp (cleaned and deveined): Choose fresh or thawed shrimp for the best juicy bite.
8 ounces linguine: Perfect for soaking up the luscious sauce with a tender bite.
1 tablespoon oil: Use a neutral oil like vegetable or canola for cooking the shrimp evenly.
1 teaspoon Cajun seasoning: The flavor powerhouse that brings vibrant spice and warmth.
1 cup half-and-half: Creates the creamy base that gently embraces the seafood.
2 tablespoons butter: Adds richness and silky texture to the sauce.
2 cloves garlic (minced): Garlic infuses a fragrant punch without overpowering.
Chopped parsley (a few sprigs): Gives a fresh, herbal note and lively green color.
1 Roma tomato (finely diced): Adds slight acidity and a pop of color to balance creaminess.
¼ cup Parmigiano Reggiano cheese: Sharp, nutty, and melts perfectly into the sauce.
1 tablespoon lemon juice (optional): Brightens the sauce and adds subtle tang, used carefully to avoid curdling.
Salt and pepper to taste: To season and round out all the flavors thoughtfully.

How to Make Shrimp & Crab Pasta with Creamy Cajun Sauce Recipe

Step 1: Prep and Season the Shrimp

Start by patting your cleaned shrimp dry with paper towels to ensure they sear beautifully instead of steaming. Lightly season with salt, pepper, and half of your Cajun seasoning to infuse that irresistible spice layer from the very beginning.

Step 2: Cook the Linguine

Bring a large pot of salted water to a boil and cook your linguine just until al dente, as it will continue absorbing the creamy sauce later. Drain and set aside so it’s ready to mingle with the seafood and sauce shortly.

Step 3: Sauté Shrimp and Garlic

Heat your pan over medium heat before adding oil and butter. Place the shrimp neatly in one layer, allowing them to develop a lovely sear without overcrowding. Add the minced garlic and cook for 2 minutes, then flip the shrimp and cook another 1 to 2 minutes until pink and fully cooked—a sign they’re bursting with flavor.

Step 4: Create the Creamy Sauce

Pour in the half-and-half and sprinkle in the Parmigiano Reggiano cheese. Whisk gently as the mixture approaches a gentle boil, about 2 minutes, encouraging the cheese to melt into a silky, indulgent sauce that’s rich but never heavy.

Step 5: Combine Pasta with Sauce

Switch off the heat, then add your cooked linguine to the pan. Stir in the diced tomato, chopped parsley, and the remaining Cajun seasoning for added kick. If you’re using lemon juice, squeeze it in now with the heat off to prevent the cream from curdling, lifting the dish with a fresh citrus note.

Step 6: Final Touches and Serve

Mix everything together thoroughly, allowing the sauce to thicken as it cools slightly. If it thickens too much or looks clumpy, just add a splash of half-and-half for that perfect coat on every noodle. Serve immediately while the flavors are vibrant and the sauce is luxuriously creamy.

Garnishes

Simple garnishes elevate this dish with beautiful texture and visual appeal. A sprinkle of fresh parsley adds a pop of color and herbaceous brightness. You can also grate a little more Parmigiano Reggiano on top to enhance the creamy indulgence. If you like a bit of heat, a dash of smoked paprika or extra Cajun seasoning makes a lovely finishing touch.

Side Dishes

This shrimp and crab pasta pairs wonderfully with crisp, refreshing sides. Think a light arugula salad tossed in lemon vinaigrette to cut through the richness or roasted vegetables like asparagus or bell peppers for complementary sweetness and crunch. Garlic bread is always a crowd-pleaser to soak up every last bit of that creamy sauce.

Creative Ways to Present

For a stunning presentation, twirl the pasta into neat nests on each plate and arrange the shrimp artfully on top. Serve it in wide, shallow bowls to showcase the creamy sauce’s luscious texture. For a festive touch, add a lemon wedge and a sprig of parsley on the side—instant restaurant vibes at home!

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer your Shrimp & Crab Pasta with Creamy Cajun Sauce Recipe into an airtight container and refrigerate. It will stay fresh for up to 3 days, retaining much of its luscious flavor if stored carefully.

Freezing

Freezing this pasta is possible, but be mindful that cream-based sauces can sometimes separate after thawing. If you choose to freeze, pack it tightly in freezer-safe containers and consume within 1 month for the best taste and texture.

Reheating

Reheat gently on the stovetop over low heat, stirring frequently to reincorporate the sauce. Add a splash of half-and-half or milk if the sauce has thickened too much. Avoid microwave reheating if possible to prevent uneven heating and curdling.

FAQs

Can I substitute the shrimp with only crab or another seafood?

Absolutely! You can use just crab meat or swap in scallops or firm fish. Keep cooking times adjusted accordingly since seafood varies in cooking speed.

Is this dish very spicy because of the Cajun seasoning?

The Cajun seasoning adds warmth and a pleasant kick, but it’s not overwhelmingly spicy. You can always adjust the amount to suit your heat tolerance.

Can I make this recipe dairy-free or vegan?

This recipe relies on half-and-half and butter for creaminess, so for a dairy-free version, substitute with coconut cream and vegan butter, but it will change the flavor profile slightly.

What type of pasta works best for this recipe?

Linguine is ideal because it catches the creamy sauce beautifully, but fettuccine or spaghetti would also work nicely if that’s what you have on hand.

Can I prepare parts of this dish in advance?

You can cook the pasta and prepare the shrimp in advance, storing each separately. Combine and finish the sauce just before serving to maintain freshness.
