Ingredients
For the Cajun Salmon & Shrimp
- 2 salmon fillets
- 250g shrimp (peeled and deveined)
- 2 tablespoons Cajun seasoning
- 1 tablespoon olive oil
- 1 tablespoon butter
- Salt and pepper to taste
For the Garlic Cream Sauce
- 2 tablespoons butter
- 4 cloves garlic (minced)
- 1 ½ cups heavy cream
- ½ cup grated parmesan cheese
- ½ teaspoon paprika
- ½ teaspoon black pepper
- Salt to taste
- 1 tablespoon fresh parsley (chopped)

For the Mashed Potatoes
- 4 large potatoes (peeled and cubed)
- 3 tablespoons butter
- ½ cup milk or cream
- Salt to taste
For the Green Beans
- 250g green beans (trimmed)
- 1 tablespoon olive oil or butter
- 2 cloves garlic (minced)
- Salt and pepper to taste
Instructions
- Prepare the potatoes
Boil peeled and cubed potatoes in salted water until fork-tender (about 15–20 minutes). Drain and mash with butter, milk, and salt until smooth and creamy. Set aside and keep warm. - Cook the green beans
Heat olive oil or butter in a pan over medium heat. Add garlic and sauté briefly. Toss in green beans, season with salt and pepper, and cook until tender-crisp (about 5–7 minutes). Set aside. - Season the seafood
Pat the salmon and shrimp dry. Rub both with Cajun seasoning, salt, and pepper. - Cook the salmon
Heat olive oil and butter in a skillet over medium-high heat. Sear salmon fillets skin-side down for 4–5 minutes, then flip and cook another 3–4 minutes until golden and cooked through. Remove and set aside. - Cook the shrimp
In the same pan, add shrimp and cook for 2–3 minutes per side until pink and opaque. Remove and set aside. - Make the garlic cream sauce
Reduce heat to medium. Melt butter in the same pan and sauté garlic until fragrant. Add heavy cream and bring to a gentle simmer. Stir in parmesan cheese, paprika, salt, and pepper. Cook until the sauce thickens slightly. - Combine and serve
Return shrimp (and optionally salmon) to the pan to coat in the sauce. Plate mashed potatoes, top with salmon, add shrimp, and drizzle generously with garlic cream sauce. Serve with green beans on the side and garnish with parsley.
Pro Tips for the Best Results

Don’t Overcook the Shrimp

If the sauce gets too thick, add a splash of milk or broth to loosen it.
