Begin by cleaning your shrimp and salmon; rinse them under cold water and pat dry with a paper towel. Generously coat both the shrimp and salmon with Cajun seasoning, pressing it gently into the fish for better flavor absorption. Set aside for about 10 minutes while you prepare the pan.

Heat a large skillet over medium-high heat and add a tablespoon of olive oil. Once the oil is shimmering, carefully place the seasoned salmon fillets in the skillet, skin-side down if applicable. Sear for about 4 minutes until golden brown, then flip the salmon and add the shrimp. Cook the shrimp for another 3-4 minutes until they turn pink and opaque, indicating they’re perfectly cooked. Remove everything from the skillet and set aside.

In the same skillet, lower the heat to medium and add another drizzle of olive oil if necessary. Sauté 3 minced garlic cloves for about 30 seconds, or until fragrant, stirring constantly to prevent burning. Pour in 1 cup of heavy cream and bring to a gentle simmer, allowing the sauce to thicken slightly for about 3-4 minutes. Stir occasionally until it’s rich and creamy, perfect for drizzling over the seafood.

While the sauce simmers, peel and chop 2-3 medium potatoes into even cubes. Boil them in a large pot of salted water for about 15 minutes or until fork-tender. Drain the potatoes, then return them to the pot and mash with a generous tablespoon of butter and a splash of milk, seasoning with salt and pepper to taste.

In a separate pan, bring a small amount of water to a boil and add 1 pound of green beans. Blanch for about 3 minutes until they’re vibrant and tender-crisp. Drain them quickly and then return to the pan with a tablespoon of butter. Sauté the beans for an additional 2-3 minutes, just until they are coated and warmed through.

To serve, place a generous scoop of creamy mashed potatoes on each plate. Layer the seared Cajun shrimp and salmon over the potatoes, ensuring you drizzle the garlic cream sauce lavishly over the top. Arrange the sautéed green beans alongside for a pop of color.
