  • 2 salmon fillets (skinless)
  • 8 oz shrimp, peeled and deveined
  • 8 oz linguine or fettuccine pasta
  • 2 tablespoons Cajun seasoning
  • 2 tablespoons butter
  • 1 tablespoon olive oil
  • 4 cloves garlic, minced
  • 1 cup heavy cream
  • ½ cup grated Parmesan cheese
  • Salt and black pepper to taste
  • Fresh parsley and lemon wedges for garnish

These ingredients combine to deliver a balance of heat, creaminess, and umami that’s sure to impress.

Kitchen Equipment Needed

Before diving into the cooking process, make sure you have the following tools:

  • Large pot (for boiling pasta)
  • Large skillet or sauté pan
  • Tongs or spatula (for flipping fish and shrimp)
  • Measuring spoons and cups
  • Fine grater (for Parmesan, if using a block)
  • Colander or pasta strainer
  • Sharp knife and cutting board

Step-by-Step Instructions

Step 1: Cook the Pasta

Start by cooking your pasta according to the package instructions until al dente. Reserve ½ cup of the pasta water before draining. This starchy liquid will help loosen the sauce later if needed.

Step 2: Season the Seafood

Pat the salmon and shrimp dry, then season both generously with Cajun seasoning. This step ensures bold flavor and a beautiful crust when seared.

Step 3: Sear the Salmon

In a large skillet over medium-high heat, heat 1 tablespoon of olive oil. Sear the salmon fillets for about 3–4 minutes per side, until golden brown and cooked through. Remove and set aside on a plate.

Step 4: Cook the Shrimp

In the same skillet, reduce heat to medium. Add the butter and minced garlic. Let the garlic cook for about 30 seconds until fragrant, then add the shrimp. Sauté for 3–4 minutes or until pink and opaque. Remove and set aside with the salmon.

Step 5: Make the Creamy Sauce

Pour the heavy cream into the skillet and stir in the grated Parmesan. Simmer on low heat until the sauce thickens slightly. Add salt and black pepper to taste. If the sauce gets too thick, stir in some reserved pasta water.

Step 6: Combine Everything

Add the cooked pasta to the skillet and toss to coat in the sauce. Gently return the salmon and shrimp to the pan, tossing just enough to combine. Garnish with fresh parsley and lemon wedges.

Recipe Notes & Tips

  • Don’t overcook the shrimp – They only need a few minutes and can turn rubbery if left too long.
  • Use a fish spatula – It makes flipping the salmon easier without breaking the fillets.
  • Want more heat? Add a pinch of cayenne pepper or red pepper flakes to the Cajun seasoning.
  • Cream alternative – You can use half-and-half for a lighter version, though the sauce will be thinner.
  • Parmesan tip – Freshly grated Parmesan melts better than pre-shredded, which often contains anti-caking agents.

Recipe Variations & Swaps

  • Protein swaps – Try blackened chicken or scallops instead of shrimp or salmon.
  • Vegetarian version – Skip the seafood and add sautéed mushrooms, sun-dried tomatoes, and spinach.
  • Gluten-free – Use your favorite gluten-free pasta and check that your Cajun seasoning is GF-certified.
  • Extra veggies – Add bell peppers, cherry tomatoes, or asparagus for extra nutrition and color.

Storing & Reheating Leftovers

If you’re lucky enough to have leftovers (and that’s a big “if”), here’s how to store and reheat them properly:

  • Refrigeration: Store leftovers in an airtight container for up to 3 days.
  • Reheating: Reheat gently on the stove over low heat, adding a splash of milk or water to loosen the sauce. Avoid microwaving salmon or shrimp for too long, as they can dry out.
  • Freezing: Not recommended. The cream sauce may separate and the seafood texture can suffer.

Suggested Pairings

Wine:

  • White wine – A crisp Sauvignon Blanc or buttery Chardonnay pairs beautifully with the creamy sauce and Cajun spice.
  • Rosé – A dry rosé complements both the shrimp and salmon without overpowering the dish.

Side Dishes:

  • Garlic bread or a crusty baguette
  • Simple green salad with a citrus vinaigrette
  • Roasted asparagus or broccolini for added greens

Frequently Asked Questions

Can I use frozen shrimp?

Yes! Just be sure to thaw them fully and pat them dry before seasoning and cooking.

What’s the best salmon to use?

Skinless fillets from Atlantic or wild-caught Pacific salmon work great. Make sure they’re boneless and uniform in thickness for even cooking.

Can I make this ahead of time?

You can prep components like the pasta and the cream sauce ahead, but seafood is best cooked fresh to maintain its texture.

How spicy is this dish?

It depends on your Cajun seasoning. Some blends are mild, while others pack more heat. Taste and adjust seasoning to your preference.

Can I use milk instead of cream?

You can, but the sauce won’t be as rich or thick. For a compromise, try half-and-half.

This Cajun Salmon & Garlic Butter Shrimp Pasta is the kind of meal that turns an ordinary night into something memorable. With its rich, spicy, creamy flavors and satisfying textures, it’s destined to become a favorite in your kitchen.
