- 4 Tbs. chive butter, at room temperature
- Finely grated zest of 1 lemon
- Juice of 2 lemons
- Salt and freshly ground pepper, to taste
- 1 large yellow onion, thickly sliced
- 2 lb. halibut fillet, patted dry
- 1 1/2 tsp. olive oil
Make the herb butter
In a bowl, using a fork, beat the chive butter until soft and light. Add the lemon zest and juice, and a pinch each of salt and pepper, then beat until thoroughly blended. Taste and adjust the seasonings with salt and pepper. Set aside at room temperature.
Season the halibut
Preheat an oven to 400°F. Oil a baking dish just large enough to accommodate the halibut.
Spread the onion slices in a single layer in the prepared baking dish. Scatter the thyme sprigs on top. Measure the halibut at its thickest point, then rub it with the olive oil and season lightly with salt and pepper. Place the halibut on the onions.
Roast the halibut
Roast until an instant-read thermometer inserted into the thickest part of the halibut registers 120°F. Total cooking time will be about 10 minutes per inch of thickness, but start checking 5 minutes before the halibut is scheduled to be done to avoid overcooking.
Divide the halibut among individual plates and top each serving with herb butter. Place some of the onion slices alongside and serve immediately. Serves 4.
