Cajun seasoning tweak: If you prefer less spice, opt for Creole seasoning, which is milder but still flavorful.

How to Make Cajun Salmon and Shrimp – Step-by-Step Guide

Prep the seafood. Pat salmon and shrimp dry with paper towels. Coat both with Cajun seasoning evenly for a deep, smoky crust.
Sear the salmon. In a large skillet over medium-high heat, heat olive oil and butter. Sear salmon fillets (skin-side down first if using skin-on) for 4-5 minutes per side until golden brown and just cooked through. Remove and set aside.
Cook the shrimp. In the same pan, sauté the shrimp for about 2-3 minutes per side until pink and opaque. Remove and reserve.
Sauté aromatics. Add minced garlic and red onion to the skillet. Cook for about 1 minute until fragrant.
Build the sauce. Sprinkle in flour if you’d like a thicker sauce. Add chopped spinach and cook until wilted. Pour in heavy cream and chicken broth, scraping any brown bits from the pan for flavor.
Melt in the cheeses. Stir in Parmesan and mozzarella until smooth. Season with salt, pepper, and a touch more Cajun seasoning for extra kick if desired.
Combine everything. Return the seared salmon and shrimp to the skillet. Spoon the sauce over the top and simmer for 2-3 minutes to meld all the flavors.
Serve hot. Garnish with chopped parsley and serve immediately over your choice of base.

Expert Tips for Cajun Salmon and Shrimp Perfection

Make your dish shine with these kitchen-tested secrets:

Dry the seafood: Patting the salmon and shrimp dry ensures a better sear and prevents steaming.
Don’t overcook: Salmon should flake easily and shrimp should just turn pink. Overcooked seafood turns rubbery fast.
Deglaze the skillet: Use chicken broth to lift flavorful browned bits from the pan into your sauce.
Let it rest: After simmering, let the dish sit for 2 minutes before serving — it helps flavors settle.

Perfect Pairings and Delicious Variations

Pair your Cajun Salmon and Shrimp with a variety of sides to complement its richness:

Pasta: Fettuccine or penne soaks up the creamy sauce beautifully.
Rice: Jasmine or Cajun-spiced rice makes a flavorful bed.
Mashed potatoes: Creamy potatoes match the sauce’s texture for an indulgent plate.
Vegetables: Roasted zucchini, asparagus, or green beans bring balance.
Crusty bread: Mop up every bit of the sauce with garlic toast or sourdough.

Variations to try:

Low-carb: Serve over cauliflower rice or spiralized zucchini.
Spicy version: Add cayenne or red pepper flakes to the sauce for more heat.
Gluten-free: Skip the flour or use gluten-free thickener.

Farm-Raised Seafood: A Sustainable Choice

When selecting ingredients for Cajun Salmon and Shrimp, quality matters. Farm-raised seafood is a great choice for both sustainability and nutrition when sourced responsibly.

Look for certifications like BAP (Best Aquaculture Practices) or ASC (Aquaculture Stewardship Council).
Prioritize local sources when possible, or choose imports from South America, which follow high standards.
Frozen shrimp is an excellent backup — just thaw properly before cooking.

Leftover Love: Storing & Reheating Tips

This creamy seafood dish is best fresh, but leftovers can still shine if handled properly.

Store: Refrigerate in an airtight container for up to 3 days.
Reheat: Warm gently on the stove with a splash of cream or broth to revive the sauce.
Avoid freezing: Cream-based sauces tend to separate and lose texture after thawing.

Frequently Asked Questions

How spicy is Cajun Salmon and Shrimp?

The dish has a noticeable kick thanks to the Cajun seasoning, which typically includes paprika, cayenne, garlic powder, and herbs. If you’re sensitive to spice, start with less Cajun seasoning or use a milder Creole blend. You can always add extra heat at the end if desired.

Can I use frozen shrimp and salmon for this recipe?

Absolutely. Frozen shrimp and salmon are great alternatives and often just as fresh. Thaw them in the refrigerator overnight or place them in a sealed bag in cold water for quicker thawing. Make sure to pat them dry thoroughly before seasoning and cooking to ensure a good sear.

What’s the best pasta to serve with Cajun Salmon and Shrimp?

Fettuccine and penne are top choices because they hold the creamy sauce well. You can also use linguine or even orzo for a slightly different texture. For a low-carb version, zucchini noodles or spaghetti squash are excellent substitutes.
