Ingredients

• Salmon Fillets: Choose fresh, skin-on fillets for the best flavor and texture. Wild-caught offers a more robust flavor, while farm-raised tends to be milder and more buttery.
• Shrimp: Look for large or jumbo shrimp that are peeled and deveined to save prep time. Fresh is ideal, but high-quality frozen shrimp work well when thawed properly.
• Cajun Seasoning: This signature blend provides the smoky, spicy foundation for the dish. You can use store-bought or make your own with paprika, garlic powder, onion powder, cayenne, oregano, and thyme.
• Paprika: Adds beautiful color and a subtle sweetness that balances the heat. Smoked paprika can be used for extra depth.
• Garlic: Fresh garlic cloves provide aromatic flavor to the cream sauce. Choose firm, plump bulbs without sprouting for the best flavor.
• Heavy Cream: Creates the luxurious base for the sauce. For a lighter option, half-and-half can be substituted, though the sauce will be thinner.
• Parmesan Cheese: Adds richness and helps thicken the sauce. Freshly grated provides better melting and flavor than pre-packaged options.
• Butter: Unsalted butter allows better control of the overall saltiness while adding richness to both the sauce and mashed potatoes.
• Potatoes: Yukon Golds offer a naturally buttery flavor and creamy texture, while Russets provide a fluffier result. Either works beautifully for mashed potatoes.
• Green Beans: Fresh beans provide the best texture and flavor. Look for bright, firm beans without blemishes.
• Lemon: Brightens the dish and balances the richness of the cream sauce. Fresh is essential for both the juice and optional garnish wedges.

Variations

Creole Style

Replace the Cajun seasoning with Creole seasoning for a slightly different flavor profile with more herbs and less heat. Add diced bell peppers, celery, and onions (the “holy trinity”) to the sauce for authentic Creole flavor and texture.

Mediterranean Twist

Swap the Cajun seasoning for a Mediterranean herb blend with oregano, basil, and thyme. Add sun-dried tomatoes, capers, and olives to the cream sauce, and finish with crumbled feta instead of Parmesan for a completely different flavor experience.

Dairy-Free Option

Create a dairy-free version by replacing the cream sauce with a coconut milk-based alternative. Use full-fat coconut milk, add a touch of nutritional yeast for cheesy flavor, and incorporate lemon zest for brightness. For the mashed potatoes, use olive oil and dairy-free milk instead of butter and regular milk.

How to Make the Recipe

Step 1: Season and Cook the Seafood

Start by patting the salmon and shrimp dry, which is crucial for achieving a perfect sear. Thoroughly coat both with the Cajun seasoning mixture, ensuring even coverage for consistent flavor. Cook the salmon skin-side down first to create a crispy skin and lock in moisture, then flip to finish. Remove the salmon before cooking the shrimp in the same pan, which infuses them with the salmon’s flavor while ensuring they remain tender and juicy.

Step 2: Create the Garlic Cream Sauce

Sauté the garlic in the same skillet where you cooked the seafood to build layers of flavor. Keep the heat medium-low to prevent burning the garlic, which can turn bitter. Slowly incorporate the cream while stirring continuously for a smooth, lump-free sauce. Add the Parmesan gradually, allowing each addition to melt completely before adding more. The lemon juice should be added at the end to prevent curdling the cream.

Step 3: Prepare the Mashed Potatoes

Start with cold water when boiling the potatoes for even cooking from the inside out. After draining, return the potatoes to the hot pot for a minute to evaporate excess moisture, resulting in fluffier mashed potatoes. Add warm (not cold) milk and butter for the smoothest texture. For extra-creamy potatoes, use a potato ricer or food mill instead of a standard masher.

Step 4: Cook the Green Beans

For perfectly crisp-tender green beans, blanch them in boiling water for 2-3 minutes before sautéing. This pre-cooking step ensures they’re cooked through while maintaining a vibrant green color and slight crunch. After sautéing, finish with a small squeeze of lemon juice to brighten their flavor and complement the seafood.

Step 5: Plate and Serve

Create a foundation with the mashed potatoes in the center of each plate. Position the salmon fillet on top and arrange the shrimp around it. Pour the cream sauce generously over the seafood, allowing it to cascade onto the potatoes. Arrange the green beans to the side for color contrast. Garnish with fresh herbs and lemon wedges just before serving for the most vibrant presentation.

Tips for Making the Recipe

• Timing is Everything: Start the potatoes first as they take the longest, then prepare the green beans and seafood while they cook.
• Don’t Overcook the Seafood: Salmon is best served medium to medium-well for optimal moisture retention. Shrimp should be cooked just until they turn pink and opaque.
• Room Temperature Ingredients: Allow salmon to sit at room temperature for 15-20 minutes before cooking for more even results.
• Sauce Consistency: If your sauce becomes too thick, thin it with a splash of chicken broth rather than more cream to maintain flavor balance.
• Test Potato Doneness: Pierce potatoes with a fork rather than following strict timing—they’re done when the fork slides in easily with no resistance.
• One Pan Technique: Cook components in sequence in the same pan when possible (seafood, then sauce) to build flavors and reduce cleanup.

How to Serve

Present this impressive dish on warmed plates to keep everything at the perfect temperature. The mashed potatoes should form a base in the center of the plate, topped with the salmon fillet and surrounded by several shrimp. Pour the garlic cream sauce generously over the seafood, allowing it to pool slightly around the potatoes. Arrange the green beans to one side for a pop of color.

For an extra touch of elegance, garnish with finely chopped fresh parsley and a small wedge of lemon. This dish pairs beautifully with a crisp white wine such as Sauvignon Blanc or Pinot Grigio, which can cut through the richness of the cream sauce while complementing the delicate seafood flavors.

For a complete dining experience, consider serving with a light starter such as a simple green salad with vinaigrette dressing to balance the richness of the main course.

Make Ahead

This elegant meal can be partially prepared in advance to reduce day-of cooking stress:

Mashed Potatoes: Can be made up to 2 days ahead and stored in an airtight container in the refrigerator. Reheat in the microwave with a splash of milk, or in a covered dish in a 350°F oven until warmed through, stirring occasionally.

Green Beans: Blanch the green beans up to a day ahead, then refrigerate. Complete the sautéing just before serving for the best texture and color.

Cajun Seasoning Mix: Prepare the spice blend up to a month ahead and store in an airtight container at room temperature.

Seafood Prep: Clean and devein shrimp up to 24 hours ahead, storing them covered in the refrigerator. Season both the shrimp and salmon up to 2 hours before cooking for enhanced flavor.

The garlic cream sauce is best made fresh, but all ingredients can be measured and prepped ahead of time for quick assembly.

FAQs

Can I use frozen seafood for this recipe?

Yes, but ensure it’s completely thawed and pat dry before seasoning. Frozen seafood often releases more moisture during cooking, which can prevent proper searing and dilute the sauce. Thaw shrimp overnight in the refrigerator or in a colander under cold running water if you’re short on time. Salmon should always be thawed slowly in the refrigerator for best texture.

How spicy is this dish and can I adjust the heat level?

The spice level is moderate with standard Cajun seasoning. To reduce heat, use less Cajun seasoning and increase the paprika and garlic powder proportionally. For a spicier version, add a pinch of cayenne pepper or red pepper flakes to the seasoning mix. You can also serve with hot sauce on the side for individual heat adjustment.

What can I substitute for heavy cream to make it lighter?

For a lighter version, substitute half-and-half or whole milk mixed with 2 tablespoons of cornstarch (to maintain thickness). Be careful not to boil these alternatives as they may separate. Greek yogurt mixed with a little milk can also work as a tangy, protein-rich alternative, added off the heat at the end of cooking.

How do I know when the salmon is perfectly cooked?

Perfectly cooked salmon should be opaque on the outside but still slightly translucent in the center. It should flake easily with a fork but remain moist. For most fillets, this means cooking for about 4-5 minutes per side, depending on thickness. A quick-read thermometer should register 125°F for medium-rare or 130°F for medium doneness.
