Step‑by‑Step Instructions for shrimp & crab pasta with creamy cajun sauce
Step 1: Prepare the Shrimp
Begin by patting the shrimp dry with a paper towel to remove excess moisture, which helps them sear better. Season the shrimp with salt, pepper, and half of the Cajun seasoning for vibrant flavor. Set this seasoned shrimp aside to absorb the seasoning while you prepare the pasta and sauce.
Step 2: Cook the Pasta
In a large pot, bring salted water to a rolling boil over high heat. Add linguine and cook according to package directions, typically about 9-11 minutes, until al dente. Stir occasionally to prevent sticking, and then drain the pasta in a colander, reserving about a cup of the pasta water for later use.
Step 3: Heat the Pan
In a large skillet, heat a blend of oil and butter over medium heat until melted and bubbling, about 1-2 minutes. Make sure the butter is foamy but not browned, as this will give depth to the shrimp & crab pasta with creamy Cajun sauce. This aromatic mixture will enhance the flavors of the seafood beautifully.
Step 4: Cook the Shrimp
Add the seasoned shrimp to the hot skillet in a single layer, allowing space between them. Cook for about 2 minutes on one side until they turn pink and opaque, then gently flip them over. Add minced garlic and cook for an additional 1-2 minutes, ensuring the garlic doesn’t burn while the shrimp fully cook and develop a beautiful golden color.
Step 5: Create the Sauce
Reduce the heat slightly and pour in the half-and-half to the shrimp mixture, stirring gently to combine. Then, add the grated Parmigiano Reggiano cheese and whisk continuously for about 2 minutes until the sauce thickens slightly and becomes creamy. Check that the sauce is gently simmering but not boiling.
Step 6: Combine with Pasta
Turn off the heat, and immediately stir in the cooked linguine, chopped Roma tomato, and chopped parsley. Mix well so that every strand of pasta is coated in the creamy Cajun sauce. Ensure that the flavors meld beautifully, bringing the dish’s elements into harmony.
Step 7: Add Lemon and Adjust
If desired, squeeze fresh lemon juice over the pasta while it’s still in the skillet to brighten the flavors. For added creaminess, you can splash in a bit more half-and-half if the sauce seems thick. Gently toss everything once more, ensuring a delightful balance of seafood and sauce.
Step 8: Serve and Enjoy
Immediately plate your luscious shrimp & crab pasta with creamy Cajun sauce. Garnish with additional parsley and, if you like, a few extra shavings of Parmigiano Reggiano. This dish is best enjoyed fresh, allowing the rich flavors and creamy sauce to shine in every bite!

Make Ahead Options
These shrimp & crab pasta with creamy Cajun sauce are perfect for busy weeknights! You can prepare the sauce up to 24 hours in advance by cooking the shrimp, garlic, and creamy components, then refrigerating them in an airtight container. To maintain the sauce’s creamy texture, store it separately from the cooked linguine and any fresh herbs. When you’re ready to serve, simply reheat the sauce gently on the stove, adding a splash of half-and-half if necessary to keep it smooth. Cook the pasta fresh just before serving to ensure excellent quality and a delightful dining experience with minimal effort!
Expert Tips for Shrimp & Crab Pasta
Timing is Key: Ensure your shrimp are cooked just until pink and tender. Overcooking can lead to rubbery shrimp, so monitor the time closely.
Creamy Consistency: If your sauce seems too thick, add a splash of reserved pasta water or extra half-and-half to achieve the desired creaminess in your shrimp & crab pasta with creamy Cajun sauce.
Spice Level: Tailor the heat to your preference by adjusting the Cajun seasoning. Start with less, and add more gradually if you love a kick!
Fresh Ingredients: Use fresh garlic and herbs whenever possible to enhance the dish’s flavor and aroma, elevating your pasta experience.
Sautéing Technique: Sauté the garlic briefly before adding the shrimp for an aromatic base that deepens the overall flavor profile of the dish.

Absolutely! Look for shrimp that has a firm texture and a mild, sea-like smell. Fresh shrimp should be slightly translucent and have a clean appearance; avoid any with dark spots or a strong fishy odor.
What are the best storage methods for leftover pasta?
Very good question! Store your shrimp & crab pasta in an airtight container in the refrigerator for up to 2 days. When reheating, gently warm it on the stove, adding a splash of half-and-half to keep the sauce creamy and smooth.
