Ingredients You’ll Need

The magic of this shrimp & crab pasta with creamy cajun sauce lies in its simple ingredients, each playing a crucial role in delivering a balanced, restaurant-worthy dish. Stick with this list and you’ll be rewarded with amazing texture, flavor, and that signature Cajun flair.

• Shrimp: Choose fresh, cleaned, and deveined shrimp for juicy, sweet bites that soak up all that luscious sauce.
• Linguine: This pasta shape is perfect for catching the creamy Cajun sauce in every strand, holding onto all the goodness.
• Oil: A neutral oil, like canola or olive oil, prevents sticking and helps the shrimp sear perfectly.
• Cajun seasoning: The heart of this recipe, lending just the right smoky heat and southern charm. Adjust to your taste!
• Half-and-half: Offers rich, creamy decadence without being too heavy—your sauce’s secret weapon.
• Butter: Adds a glossy finish and extra layer of flavor to both shrimp and sauce.
• Garlic: Fresh minced garlic infuses the dish with aromatic warmth and depth.
• Chopped parsley: Sprigs of parsley bring freshness and a pop of bright green that wakes up the entire plate.
• Roma tomato: Diced for texture, color, and a subtle tang that cuts through the creamy sauce.
• Parmigiano Reggiano cheese: Melts right into the sauce, providing sharp, savory notes and silky body.
• Lemon juice (optional): A squeeze at the end lifts the flavors and balances the richness—add slowly and with the heat off to avoid curdling.
• Salt and pepper: Fine-tune every flavor and enhance every bite.

How to Make shrimp & crab pasta with creamy cajun sauce

Step 1: Prep and Season the Shrimp

Start by gently patting your cleaned shrimp dry with a paper towel. This simple step ensures they’ll sear beautifully instead of steaming. Sprinkle them with salt, pepper, and half of the Cajun seasoning. Toss to coat—this gives the shrimp a head start on flavor, letting the Cajun spices gently infuse every bite.

Step 2: Cook the Linguine

Set a large pot of salted water to boil and add your linguine. Cook according to package instructions until just al dente—this means tender, but with a tiny bit of bite. Drain well and set aside; don’t worry, the pasta will finish cooking in the sauce, soaking up even more delicious flavor.

Step 3: Sauté the Shrimp and Garlic

Heat a large pan over medium and add a swirl of oil along with the butter. Once it sizzles, arrange the seasoned shrimp in a single layer and add the garlic. Let them cook undisturbed for about 2 minutes, then flip and cook another 1–2 minutes, just until pink and opaque. Remove the shrimp from the pan if they’re done early to avoid overcooking; they’ll return to the sauce soon.

Step 4: Create the Creamy Cajun Sauce

Pour in the half-and-half and add the Parmigiano Reggiano cheese, whisking the mixture as it gently comes to a boil. This is when the sauce turns silky and luscious. Keep whisking for 2 minutes until it thickens slightly. Then turn off the heat—this part is key, especially when you go to add the lemon juice later.

Step 5: Toss Everything Together

Slide the cooked linguine into the pan, add the cooked shrimp (plus crab if you have some for a true “shrimp & crab pasta with creamy cajun sauce”), and toss to coat. Sprinkle in the diced Roma tomatoes, chopped parsley, and the remaining Cajun seasoning. Now’s the moment for that optional lemon juice—just a little squeeze, with the heat still off, to keep the sauce silky. Mix everything together and watch as the sauce wraps every noodle and piece of seafood in creamy, spicy perfection.

Step 6: Adjust and Serve

If your sauce feels a bit too thick or clumpy, no worries! Add a splash of half-and-half, stirring until it loosens up and turns glossy again. Serve the shrimp & crab pasta with creamy cajun sauce immediately, while it’s steaming hot and at its most irresistible.

Garnishes

Nothing elevates this dish more than a finishing flourish of color and freshness. Top your shrimp & crab pasta with creamy cajun sauce with extra chopped parsley, a dusting of Parmigiano Reggiano, and a squeeze of fresh lemon. If you want even more Cajun flair, a pinch of extra seasoning or a dash of hot sauce will make it pop.

Side Dishes

Round out your plate with a crisp green salad dressed in vinaigrette or a simple Caesar, and maybe a basket of warm, crusty bread to mop up every last drop of sauce. Roasted asparagus or sautéed green beans also make a lovely, vibrant pairing, balancing the richness of the pasta.

Creative Ways to Present

For a show-stopping effect, serve the pasta in a shallow bowl and artfully pile extra shrimp and crab on top, along with a nest of fresh herbs. You can also portion the dish into small ramekins for a fancy appetizer, or even spoon it into hollowed-out roasted bell peppers for a playful twist on presentation.

Make Ahead and Storage

Storing Leftovers

Store any leftover shrimp & crab pasta with creamy cajun sauce in an airtight container in the refrigerator. It will stay fresh and flavorful for up to 2 days—even after sitting, that bold Cajun flavor sinks deeper into the seafood and pasta.

Freezing

While cream-based pasta sauces are best enjoyed fresh, you can freeze portions of this dish if you need to. Spoon cooled pasta into freezer-safe containers, seal tightly, and freeze for up to 1 month. Just know that the sauce may separate slightly when thawed, but a gentle reheat (and a splash of half-and-half) works wonders.

Reheating

Reheat your shrimp & crab pasta with creamy cajun sauce gently on the stovetop over low heat, adding a splash of cream or half-and-half as needed to restore its creamy consistency. Avoid microwaving at high power, as this can make the shrimp rubbery and the sauce prone to separating.

FAQs

Can I use precooked shrimp or imitation crab?

Yes, you can. Just add the seafood at the very end, only long enough to warm through, since it’s already cooked—this keeps it from turning rubbery or dry.

What other types of pasta work with this recipe?

Absolutely! Fettuccine, penne, or spaghetti all work beautifully in shrimp & crab pasta with creamy cajun sauce; just choose your favorite and cook to al dente.

Can I make this gluten-free?

You can swap the linguine for your favorite gluten-free pasta. Double-check that your Cajun seasoning is also gluten-free to keep things safe for everyone.

How spicy is this dish?

The spice level is totally customizable! The recipe calls for a moderate amount of Cajun seasoning, but you can easily dial it up or down based on your personal preference. Add hot sauce at the end for extra heat.

Can I add vegetables to make it heartier?

Definitely. Bell peppers, spinach, or even mushrooms are fantastic additions—simply sauté them before adding the shrimp for even more flavor and nutrition in your shrimp & crab pasta with creamy cajun sauce.
