Ingredients for Sheet Pan Herb-Roasted Halibut with Garlic Green Beans and Baby Potatoes

Instructions

Preheat the oven to 425°F (220°C) and line a large rimmed sheet pan with parchment paper or lightly grease it.
In a large bowl, toss baby potatoes with 1 tablespoon olive oil, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and half of the dried oregano and thyme.
Arrange the potatoes on one side of the sheet pan in a single layer. Roast for 10 minutes.
Meanwhile, toss the green beans with the remaining 1 tablespoon olive oil, minced garlic, the remaining oregano and thyme, paprika, and a pinch of salt and pepper.
After potatoes have roasted for 10 minutes, remove the pan and shift the potatoes to one side to make room for green beans and halibut.
Spread the green beans evenly beside the potatoes on the sheet pan.
Place halibut fillets spaced evenly on the pan. Season generously with salt and pepper and top each fillet with lemon slices.
Return the sheet pan to the oven and roast for 12-15 minutes, until halibut is opaque and flakes easily, potatoes are tender, and green beans are crisp-tender.
Remove from oven and garnish with fresh chopped parsley.
Serve immediately for a fresh, healthy Mediterranean sheet pan dinner.
