Ingredients
For the Salmon
- 2 salmon fillets (about 180–200 g each, skin-on)
- 1 tablespoon olive oil
- 1 tablespoon butter
- 1 teaspoon Cajun seasoning
- Salt and freshly ground black pepper
For the Shrimp
- 200 g large shrimp, peeled and deveined
- 1 tablespoon butter
- 1 ½ teaspoons Cajun seasoning
- 1 garlic clove, minced
- Juice of 1 lemon
For the Cajun Cream Sauce
- 1 tablespoon butter
- 2 garlic cloves, minced
- 250 ml heavy cream
- 50 g grated Parmesan cheese
- 1 teaspoon Cajun seasoning
- Salt and pepper, to taste
- 1 tablespoon chopped parsley (for garnish)
For the Mashed Potatoes
- 3 large potatoes, peeled and cut into chunks
- 3 tablespoons butter
- 80 ml hot milk or cream
- Salt and black pepper, to taste
Step-by-Step Instructions
1. Master the Mashed Potatoes
- Place the peeled and cut potatoes into a large pot of salted water.
- Bring to a boil and cook until tender — about 15–20 minutes.
- Drain thoroughly, then mash the potatoes while they’re still hot.
- Add butter and hot milk (or cream) gradually, mashing until smooth and creamy.
- Season with salt and black pepper to taste.
- Keep warm while you prepare the seafood and sauce.
Tip: For extra smooth mashed potatoes, use a potato ricer or electric hand mixer.
2. Cook the Salmon
- Pat the salmon fillets dry with a paper towel — this ensures a crisp sear.
- Rub each fillet with Cajun seasoning, salt, and black pepper.
- Heat olive oil and butter in a skillet over medium heat.
- Place the salmon skin-side down and cook for 4–5 minutes until crispy.
- Carefully flip and cook for another 2–3 minutes, depending on thickness.
- Remove from the skillet and set aside on a plate.
Pro Tip: Don’t overcrowd the pan. Searing in batches helps maintain an even crust.
3. Prepare the Shrimp
- In the same skillet, melt the butter.
- Add minced garlic and sauté for 30 seconds until fragrant.
- Add the shrimp, sprinkle with Cajun seasoning, and cook for 1½–2 minutes on each side until pink and lightly charred.
- Squeeze lemon juice over the shrimp for brightness.
- Remove and set aside.
4. Make the Cajun Cream Sauce
- Melt the butter in the same skillet (don’t wash it — the flavor from the seafood adds depth).
- Add garlic and sauté briefly.
- Pour in heavy cream and let it simmer gently for 2–3 minutes.
- Stir in grated Parmesan cheese and Cajun seasoning until the sauce becomes rich and velvety.
- Taste and season with salt and pepper as needed.
- Return the cooked shrimp to the sauce and toss to coat evenly.
5. Assemble the Dish
- Spoon a generous portion of creamy mashed potatoes onto a plate.
- Place a salmon fillet on top.
- Spoon the Cajun shrimp and sauce over the salmon, letting the creamy sauce drip down the sides.
- Garnish with freshly chopped parsley for color and freshness.
Serve immediately — the creamy sauce, flaky salmon, and soft potatoes are best enjoyed hot.
Tips for Success
- Use fresh seafood: Fresh salmon and shrimp yield better texture and flavor than frozen ones.
- Control the spice: If you prefer a milder dish, reduce the Cajun seasoning or mix it with paprika.
- Enhance the sauce: A splash of white wine or chicken stock can deepen the sauce’s flavor.
- Don’t skip the lemon: The citrus balances the creamy sauce and keeps the dish vibrant.
- Keep the potatoes warm: Store them in a covered bowl or pot while preparing the seafood.
Variations
- Swap the seafood: Try scallops or white fish instead of salmon for variety.
- Add vegetables: Serve with sautéed spinach, asparagus, or roasted broccoli for a balanced meal.
- Make it lighter: Substitute light cream or Greek yogurt for a lower-calorie version.
- Go extra creamy: Add a tablespoon of cream cheese to the mashed potatoes for extra richness.

FAQs
Can I use frozen shrimp or salmon?
Yes, but make sure to thaw them completely and pat them dry before cooking. Excess moisture prevents proper searing.
What if I don’t have Cajun seasoning?
You can make your own by mixing paprika, garlic powder, onion powder, cayenne, oregano, and thyme.
Can I make the sauce ahead of time?
Yes, you can prepare the Cajun cream sauce and refrigerate it for up to 2 days. Reheat gently before serving.
What type of potatoes are best for mashing?
Yukon Gold or Russet potatoes work best — they’re fluffy, smooth, and creamy when mashed.
How can I make the dish spicier?
Add a pinch of cayenne pepper or a few dashes of hot sauce to the Cajun cream sauce.
