How to Make It
Here’s how to prepare your Cajun shrimp and salmon dinner:
1. Boil the Potatoes
Fill a large pot with salted water and add the russet potatoes. Bring to a boil over high heat and cook for 15-20 minutes until fork-tender.
2. Mash the Potatoes
Drain the cooked potatoes in a colander and return them to the pot. Mash them until smooth, then add the butter and milk, continuing until creamy. Season with salt and pepper to taste.
3. Prepare the Seafood
Pat the shrimp and salmon fillets dry with paper towels. Generously season both sides with Cajun seasoning.
4. Sear the Shrimp
Heat olive oil in a large skillet over medium-high heat. Add the shrimp in a single layer and cook for 2-3 minutes on each side until pink and opaque. Remove from the skillet and set aside.
5. Cook the Salmon
In the same skillet, add the butter and let it melt. Add the salmon fillets, skin side down if applicable. Cook for 4-5 minutes on each side until cooked through and flaky. Set aside with the shrimp.
6. Make the Cream Sauce
Melt 1 tablespoon of butter in the same skillet over medium heat. Add minced garlic and sauté for 1-2 minutes. Then, add heavy cream, chicken broth, Dijon mustard, salt, black pepper, and smoked paprika. Stir and bring to a simmer, cooking for 4-5 minutes until slightly thickened.
7. Combine Seafood with Sauce
Return the cooked shrimp and salmon to the skillet and spoon the sauce over them. Let simmer together for an additional 2-3 minutes.
8. Cook the Green Beans
Bring a pot of salted water to a boil. Add green beans and cook for 3-4 minutes until tender-crisp. Drain and set aside.
9. Sauté the Green Beans
In a large skillet, melt butter over medium heat. Add minced garlic and red pepper flakes (if using), and sauté for 1-2 minutes. Add cooked green beans, tossing to coat, and sauté for 3-4 minutes until slightly caramelized. Season with salt and pepper to taste.
10. Plate the Dish
Scoop mashed potatoes onto each plate, top with a salmon fillet and a few Cajun shrimp, then spoon the garlic cream sauce over all. Place sautéed green beans on the side.
How to Store It
Fridge: Store in an airtight container for up to 3 days.
Freezer: No, seafood doesn’t freeze well.

- Use fresh seafood for the best flavor and texture.
