Your Ingredients List

  • 4 large shrimp, peeled and deveined
  • 2 salmon fillets (6 oz each), skin on or off depending on preference
  • 2 tablespoons Cajun seasoning: A blend of paprika, cayenne, garlic powder, onion powder, thyme, and oregano for bold, spicy flavor.
  • 1 tablespoon olive oil: For searing the shrimp and salmon.
  • 1 tablespoon butter: To add flavor when cooking the seafood.
  • 1 tablespoon butter: For sautéing garlic and creating the base for the cream sauce.
  • 3 cloves garlic, minced: Fresh garlic brings an aromatic base to the sauce.
  • 1 cup heavy cream: For a rich, velvety texture.
  • 1/4 cup chicken broth: To thin the sauce slightly and enhance the flavor.
  • 1 teaspoon Dijon mustard: Adds a tangy flavor that complements the creaminess.
  • 1/4 teaspoon salt: To taste.
  • 1/4 teaspoon freshly ground black pepper: To taste.
  • 1/4 teaspoon smoked paprika: For a smoky depth to the sauce.

  • 1/4 cup butter: To add richness and flavor to the mashed potatoes.
  • Salt and pepper: To taste.

My Go-To Equipment

I keep a few tools close when I make this. I use a large heavy pot for the potatoes. I use a wide skillet that holds the shrimp and salmon without crowding. I grab a potato masher or a hand mixer for smooth mash. I also like tongs for flipping fish and a slotted spoon for the green beans. A good thermometer helps if you want perfect salmon every time.

I often tell readers to have a plate ready for resting the seafood. It saves time. If you want ideas for sides with a bit more comfort, try my country ranch green beans and potatoes with bacon for a heartier green bean side.

Cajun Shrimp and Salmon with Garlic Cream Sauce, Mashed Potatoes, and Green Beans: A Flavor-Packed Dinner to Impress

Healthy Twists on a Classic

I like to trim calories and keep the taste. I swap half and half for heavy cream when I want a lighter sauce. I steam the green beans instead of sautéing to cut butter. I sometimes use Yukon gold potatoes for a smoother mash with less milk. For a spice tweak, use less Cajun seasoning and add a squeeze of lemon to the sauce for a bright finish. If you prefer an oven route, try my take on a one pan dinner like the sheet pan chicken and sweet potatoes with broccoli and apples for a simpler weeknight swap.

Serving Suggestions From My Table

I serve this on wide, warm plates. I spoon the mashed potatoes down first so the cream sauce can spread. I place the salmon on top and tuck shrimp beside it. I put green beans on the side so they stay crisp. I like a lemon wedge and a small sprig of parsley on the fish. For bread, I offer crusty rolls to soak up the sauce. For a light wine pairing, I choose a chilled Sauvignon Blanc. For a no fuss soup to start, I often recommend a warm bowl of potato soup from my other recipes like my potato soup recipe with lentils when the night needs extra comfort.

Getting It Just Right

Cook time matters here. Do not overcook the salmon or shrimp. I pull the shrimp when they are just opaque. I stop the salmon when it flakes with a fork but still looks moist. Let the cream sauce simmer gently so it does not break. Taste the sauce before you finish. Salt and a squeeze of lemon can lift the whole dish. Keep the mashed potatoes warm under a lid so they stay fluffy.

If your sauce looks thin, simmer it a bit longer to reduce. If it is too thick, add a splash of chicken broth or milk. For even cooking, let the salmon sit at room temperature for 15 minutes before you sear it. This step helps it cook evenly. I use the stove heat I know well and move the pan to a lower flame if it gets too hot.

How to Store Leftovers

Store leftovers in shallow airtight containers. Keep the sauce with the seafood to keep flavor. Refrigerate up to three days. Reheat gently on the stove over low heat. Add a splash of milk or broth to loosen the sauce when reheating. Do not reheat seafood too long as it can dry out. For mashed potatoes, reheat with a little milk and stir until smooth. Green beans reheat well in a skillet with a touch of butter.

You can freeze the mashed potatoes for up to two months in a freezer bag. Label the containers so you know the date. I never freeze cooked fish with cream sauce. The texture changes too much. If you must freeze seafood, freeze the plain cooked fish and thaw gently before pairing with a fresh sauce.

Enjoy Every Moment

I make this recipe when I want a meal that feels like a hug. I like the mix of spice and cream. I like how fast it comes together when I plan. I hope you make it for someone you love and make new memories at your table.
