This creamy Cajun salmon and shrimp recipe makes seafood night seriously special with juicy fillets and plump shrimp nestled in a rich sauce. Budget-friendly Monterey Jack cheese and fresh baby spinach boost flavor and texture. I love serving this with mashed potatoes and a side vegetable for a complete comfort meal that is always requested on busy weeknights.
The first time I made this, I was surprised at how perfectly the creamy sauce complemented the spice. Now it is my go-to when I want to wow dinner guests without fuss.
Ingredients
- Unsalted butter: gives a rich base and helps the sauce come together Look for fresh or high-quality butter for best taste
- All-purpose flour: thickens the sauce just enough so it coats the seafood Use a fresh bag for a lump-free sauce
- Cajun seasoning: delivers the zest and heat Use your favorite blend or make your own to control the spice level
- Paprika: ups the smoky depth and color Spanish paprika has the best flavor
- Heavy cream: adds luxurious body Try to use full-fat for silkiness
- Chicken broth: lightens the creamy sauce and gives more savory notes Go with low sodium so the dish is not too salty
- Monterey Jack cheese: melts smoothly for creaminess Shred your own for optimal melt
- Fresh baby spinach: offers freshness and color Choose bright green leaves without wilting
- Salmon fillets: taste rich and stand up to robust spices Buy center-cut pieces that are similar in thickness
- Jumbo shrimp: add sweetness and variety Wild-caught or responsibly farmed shrimp make a big difference
- Vegetable oil: is used along with butter for frying and helps the salmon brown nicely Go with a neutral kind like canola or grapeseed
- Fresh parsley: provides a pop of color and contrast Always choose bright green and fresh for garnish
Step-by-Step Instructions
- Melt and Flavor the Butter:
- Melt unsalted butter in a large skillet over medium heat The butter should bubble and become fragrant but not brown
- Begin the Sauce Base:
- Sprinkle the flour Cajun seasoning and paprika onto the melted butter Whisk vigorously to smooth out any lumps Let this mixture fry gently for about one minute so the spices bloom
- Build the Creamy Sauce:
- Slowly pour in the heavy cream and chicken broth while whisking constantly Keep whisking until everything comes together in a smooth sauce
- Simmer to Thicken:
- Bring the sauce to a gentle simmer Turn the heat to low and let it bubble for about ten minutes Stir occasionally until thick enough to coat a spoon
- Season the Salmon:
- Pat salmon fillets dry and dust both sides with half of the Cajun seasoning Press gently so the spice sticks
- Sear the Salmon:
- In a separate skillet over medium heat melt some butter with vegetable oil When hot add the seasoned salmon fillets Cook each side three to four minutes until just cooked through The flesh should easily flake but still appear moist Transfer salmon to a plate and tent loosely with foil to keep warm
- Cook the Shrimp:
- Toss the shrimp with the remaining Cajun seasoning Add them to the skillet after the salmon is done Cook each side two to three minutes until they are pink and opaque Remove pan from heat
- Finish the Sauce:
- Stir Monterey Jack cheese and baby spinach into your simmering sauce Let it cook a few more minutes until the cheese is fully melted and the spinach is wilted
- Combine and Serve:
- Nestle the cooked salmon and shrimp into the creamy sauce Spoon sauce over the top and sprinkle with fresh parsley Serve immediately over mashed potatoes or rice

My favorite ingredient here is the Monterey Jack cheese which melds everything together with melty silkiness. This meal brings back memories of cozy family celebrations when everyone gathered in the kitchen for a taste before dinner even hit the table.
Storage Tips
Leftovers keep well in an airtight container in the fridge for up to two days Gently reheat on the stove over low heat adding a splash of broth if the sauce tightens up Too much reheating will dry out the seafood so aim for just-warmed through
Ingredient Substitutions
If you do not have Monterey Jack cheese you can swap in mozzarella or mild cheddar For the greens try arugula in place of spinach If needed half and half works instead of heavy cream just simmer a bit longer to reduce
Serving Suggestions
This dish really shines over fluffy mashed potatoes rice or even creamy polenta You can also pair it with a bright green salad or roasted asparagus For a festive look add lemon wedges on the side
