Step-by-Step Instructions
Cooking shrimp and salmon over mashed potatoes with Cajun cream sauce is a straightforward process when broken down into clear steps. Each component—mashed potatoes, Cajun-spiced salmon and shrimp, and the optional cream sauce—is cooked separately and then assembled for a beautiful, restaurant-quality plate.
A. Prepping the Ingredients
Pat the seafood dry using paper towels. This helps achieve a better sear.
Season the shrimp and salmon with Cajun seasoning, salt, and pepper. Rub gently to coat evenly.
Mince the garlic and chop parsley for garnish.
Peel and cube the potatoes, placing them in water to prevent oxidation before boiling.
This preparation sets the stage for efficient cooking and consistent flavor throughout the dish.
B. Making the Mashed Potatoes
In a medium saucepan, boil the cubed potatoes in salted water until fork-tender (about 15 minutes).
Drain the potatoes using a colander and return them to the hot pot to steam dry for 1–2 minutes.
Add butter, heavy cream, and sour cream. Mash using a masher or ricer until smooth and creamy.
Season with salt and pepper to taste. Cover and set aside.

C. Cooking the Salmon
Heat olive oil in a skillet over medium-high heat.
Place the salmon fillets skin-side down (if the skin is on). Sear for 3–4 minutes per side until golden and cooked through.
Remove salmon from the skillet and set aside.
Salmon is naturally rich and benefits from high heat and a short cook time. For more on salmon varieties and cooking methods, explore this salmon article.
D. Cooking the Shrimp
In the same skillet, reduce heat to medium.
Add butter and minced garlic. Cook for 30 seconds until fragrant.
Add shrimp and sear for 2–3 minutes per side until pink and opaque.
Squeeze in lemon juice and stir to coat.
Shrimp cook quickly—be careful not to overcook. Shrimp size and variety info can be found here.
E. Making the Cajun Cream Sauce (Optional)
In a small saucepan, combine 1 cup heavy cream, 1 tablespoon Cajun seasoning, and 1 clove minced garlic.
Simmer over low heat until slightly thickened (about 5 minutes).
Stir in ¼ cup grated parmesan for extra depth.
Adjust salt and pepper to taste.

Plating and Presentation Tips

Layer the salmon fillet over the potatoes, slightly off-center for visual balance.
Place 3–4 shrimp on top or around the salmon, angling them for contrast and height.
Drizzle the Cajun cream sauce around the edges of the potatoes and lightly over the seafood.
Garnish with chopped parsley or lemon zest for a fresh, bright pop of color.

Tips for Perfect Results
Executing this recipe with precision is easy if you keep a few best practices in mind:
Dry your seafood well before seasoning. Moisture prevents a good sear.
Do not overcrowd the pan when searing. Cook in batches if necessary.
Warm your cream before adding to mashed potatoes to prevent cooling.
Taste and adjust seasoning as you go, especially with bold flavors like Cajun spice.
Let cooked salmon rest for a few minutes before plating—it helps retain moisture.
For top-quality results, use fresh ingredients whenever possible and follow cooking times closely. Want to know more about using butter in cooking? Read this butter guide for extra tips.
