How to Make Cajun Shrimp and Salmon with Garlic Cream Sauce, Mashed Potatoes, and Green Beans Recipe
Step 1: Prepare the Cajun Seasoning
Start by mixing the Cajun seasoning, garlic powder, paprika, onion powder, salt, and black pepper in a small bowl. This simple blend brings layers of warm spices, ensuring our shrimp and salmon will be packed with flavor.
Step 2: Season the Seafood
Rub the seasoning mixture evenly over the shrimp and salmon fillets. Coating every inch means each bite bursts with the vibrant Cajun spice that defines this recipe.
Step 3: Sear the Salmon
Heat olive oil in a large skillet over medium-high heat. Place the salmon skin-side down first, cooking for 3 to 4 minutes to get that irresistible crispy skin. Flip the fillets and cook another 3 to 4 minutes until they’re perfectly done but still tender inside.
Step 4: Cook the Shrimp
Using the same skillet, add the shrimp and cook for 2 to 3 minutes per side. They should turn a beautiful pink and become opaque — signaling they’re juicy and ready.
Step 5: Create the Garlic Cream Sauce
Lower the heat to medium and melt butter in the skillet. Add minced garlic and sauté for about a minute until fragrant. Stir in heavy cream and chicken broth, then simmer for 5 to 7 minutes to reduce slightly. Finish by mixing in Parmesan cheese until melted and smooth.
Step 6: Combine Seafood and Sauce
Return the shrimp and salmon to the skillet, spooning sauce over everything. Let them simmer gently in this creamy garlic concoction while you prepare the sides.
Step 7: Make the Mashed Potatoes
Place peeled, diced potatoes into boiling water and cook until fork-tender, about 10 to 12 minutes. Drain and mash with milk, butter, salt, and pepper until silky smooth and creamy—the perfect canvas for that rich seafood topping.
Step 8: Cook the Green Beans
Bring another pot of water to boil and cook trimmed green beans for about 4 to 5 minutes. They should be tender yet crisp, retaining a lovely bright green color for a fresh crunch.
Step 9: Plate Your Dish
Start with a hearty scoop of mashed potatoes, lay a salmon fillet on top, and nestle the shrimp alongside. Drizzle extra garlic cream sauce over everything, then arrange the green beans neatly to the side. Garnish with fresh parsley and serve immediately for the best experience.

Garnishes
Freshly chopped parsley is the perfect garnish to add a gorgeous burst of green and a fresh, herbal brightness that cuts through the creaminess of the sauce. A lemon wedge on the side also adds a zesty brightness if you want an extra pop.
Side Dishes
While the mashed potatoes and green beans already make this dish a well-rounded plate, a simple side salad with a light vinaigrette or some crusty bread can be fantastic companions. They add texture contrasts and help mop up any leftover garlic cream sauce.
Creative Ways to Present
Serve the Cajun Shrimp and Salmon with Garlic Cream Sauce, Mashed Potatoes, and Green Beans Recipe on a large platter family-style for a festive touch. Alternatively, for an elegant dinner, arrange individual portions precisely on chilled plates and drizzle sauce artfully for an upscale feel. Adding edible flowers or microgreens can also elevate presentation.
Make Ahead and Storage
Storing Leftovers
Place any leftover Cajun Shrimp and Salmon with Garlic Cream Sauce, Mashed Potatoes, and Green Beans Recipe in airtight containers and store in the refrigerator. It keeps well for up to 3 days, making it a perfect choice for a delicious next-day meal.
Freezing
While seafood dishes with cream sauce don’t freeze as well due to texture changes, you can freeze the mashed potatoes and cooked green beans separately. Freeze mashed potatoes in a freezer-safe container for up to 2 months, and green beans wrapped tightly in foil or freezer bags for the same duration.
Reheating
Reheat the seafood gently on the stovetop over low heat to avoid overcooking. Warm the mashed potatoes in the microwave or stovetop with a splash of milk to restore creaminess. Green beans can be quickly steamed or microwaved until warm but still crisp.
