How to make Butter-roasted halibut with asparagus and olives

1. Preheat the oven to 160°C (fan) or 180°C (conventional).

2. Thinly slice one-quarter of the asparagus into coins and place them in a medium bowl; set aside.

3. Heat the butter and 2 tablespoons of oil in a small saucepan over medium heat. As soon as the butter has melted, add the Aleppo-style pepper and remove from the heat.

4. Season the fish with salt and black pepper on both sides, then place it on a rimmed baking tray. Scatter the ramps and the remaining asparagus around the fish, and season with additional salt and black pepper.

5. Pour the butter mixture over the fish and vegetables, then toss the vegetables to coat them evenly. Roast in the oven, undisturbed, until the fish is just opaque in the centre and the asparagus is bright green and tender, for 15–25 minutes, depending on the thickness of your fillets.

6. In a separate bowl, toss the olives, chives, lemon juice, 2 tablespoons of tarragon, and the remaining 5 tablespoons of oil with the reserved asparagus; season with salt and black pepper.

7. Transfer the fish to a serving platter and top with the ramps and asparagus. Spoon some of the olive mixture over the top and scatter tarragon leaves on for garnish.

8. Serve with potatoes, lemon wedges, and the remaining olive mixture alongside.
