Roasted Halibut with Miso-Glazed Sweet Potatoes

• Recipe by Peter Gordon

Ingredients

1. Ten 8-ounce halibut steaks, cut about 3/4 inch thick
2. 1/4 cup olive oil
3. 2 teaspoons thyme leaves
4. 2 tablespoons unsalted butter, melted
5. 2 tablespoons sake
6. 1 tablespoon mirin
7. 2 teaspoons soy sauce
8. 1 1/2 teaspoons yellow miso
9. 3 pounds sweet potatoes, peeled and cut into 1/2-inch dice
10. Salt and freshly ground pepper
11. 1 1/2 tablespoons fresh lime juice
12. 1/2 cup loosely packed flat-leaf parsley leaves
13. Five-Vegetable Slaw, for serving

Directions

1. Preheat the oven to 425°. Put the halibut in a large shallow dish and rub the steaks all over with the olive oil and thyme. Let stand at room temperature for 30 minutes.
2. In a large bowl, whisk the melted butter with the sake, mirin, soy sauce and miso until combined. Add the sweet potatoes and toss to coat. Spread the sweet potatoes on a large rimmed nonstick baking sheet and roast them for 35 minutes, turning once, until tender and lightly browned. 
3. Shortly before serving, heat a cast-iron grill pan until almost smoking. Season the halibut steaks with salt and pepper and grill, turning once, until they are just cooked through, about 7 minutes. Toss the sweet potatoes with the lime juice and parsley leaves. Set the halibut steaks on plates and top with the Five-Vegetable Slaw. Spoon the sweet potatoes alongside and serve immediately.
