Tips

Use fresh salmon and herbs for the best flavor.

Let the salmon marinate longer for deeper flavor; refrigerate for a few hours if possible.

Take your time caramelizing the onion—it adds richness and sweetness to the sauce.

Simmer the sauce until thickened to your liking.

Adjust the texture of your mashed potatoes by adding milk gradually.

Make sure your pan is hot before searing the salmon for a nice crust.

For a beautiful plate, serve the salmon alongside the mash and top with sauce.

Add salt and pepper to taste.

For a spicy twist, add cayenne or chili pepper.

You can also use firm white fish like cod, halibut, or tilapia as an alternative.

Stappenplan


1

Place the salmon, salt, onion powder, garlic powder, black pepper, dried parsley, and olive oil in a deep bowl. Mix well and set aside to let the flavors develop.

2

Peel and finely chop the yellow onion.

3

Heat the butter in a skillet over medium heat. Add the chopped onion and sauté for 4–5 minutes or until golden brown. Add the heavy cream, onion powder, curry powder, and dried parsley. Crumble in the stock cube, mix well, and let simmer for 5–7 minutes until the sauce thickens. Stir in the crème fraîche and cook for another 2 minutes.

4

Bring a pot half full of water to a boil. Add salt and the potatoes. Boil for 15–20 minutes or until the potatoes are tender. Drain the water.

5

Add the dried salad seasoning, black pepper, salt, butter, and milk to the potatoes. Mash until smooth or to desired consistency.

6

Heat the olive oil and butter in a skillet over medium heat. Add the salmon and cook for 3–5 minutes. Flip and cook another 2–4 minutes, depending on preferred doneness.

7

To serve, spoon some mashed potatoes onto a plate. Place a salmon fillet next to it and drizzle with onion sauce. Bismillah, enjoy your meal!
