How to Make Pan-Seared Halibut Fillets in Creamy Lemon Sauce

1. Season the halibut fillets liberally with salt and pepper on both sides. Heat 1 tablespoon of neutral oil in a large, non-stick frying pan over medium-high heat until shimmering. Add the fish and cook for 8-10 minutes, flipping once, until it flakes easily. Remove from the pan and set aside.

2. Saut the onions in the same frying pan over medium heat for 3-4 minutes until softened. Then, toss in the garlic and chopped preserved lemon, cooking for an additional minute to infuse those lovely flavors. Season with a sprinkle of salt and pepper.

3. Dissolve the white wine, garlic, and herb flavour pot in 250ml of boiling water. Pour this mixture into the pan and simmer for about 5 minutes, allowing the sauce to thicken slightly and develop a rich aroma.

4. Stir in the slice of garlic and herb butter, mixing until melted. Then, add the double cream and most of the finely chopped parsley, saving a touch for garnishing. Simmer the sauce for an additional 5 minutes for a velvety finish.

5. Return the seared halibut to the pan, generously coating it with the creamy sauce. Let it heat through while preparing your sides, ensuring every bite is drenched in that delightful mixture.

6. Microwave the mashed potatoes for 5 minutes, followed by the vegetable mix for 3 minutes until everything is heated through and ready to serve.

7. Plate the dish by adding a generous serving of mashed potatoes first, topping it with the halibut. Place the vegetables on the side, drizzle with extra creamy sauce, and finish with a sprinkle of parsley for that perfect touch.

Optional: Serve with a wedge of lemon for an extra burst of freshness.
