Halibut is such a treat, lean and delicate, and when you pair it with caramelized roasted turnips and a fragrant herb butter, you've got something truly special. Turnips are wonderfully nutritious too, packed with vitamin C and fiber to support your immune system. The best part? Everything cooks on one sheet pan with minimal fuss, so cleanup is a breeze. It's simple, elegant, and honestly, it never fails to impress.

Instructions
- 1
Preheat your grill to medium-high heat and preheat the oven to 400°F. Toss the turnip wedges with 3 tablespoons of olive oil, half the salt, and pepper on a baking sheet.
Tip: Uniform-sized turnip pieces ensure even roasting throughout.
- 2
Roast the turnips in the oven for 20-25 minutes, stirring halfway through, until golden and tender with caramelized edges.
Tip: Don't skip the stirring step to prevent burning on one side.
- 3
While turnips roast, prepare the herb butter by mixing softened butter with minced garlic, lemon zest, 4 chopped sage leaves, and a pinch of salt and pepper in a small bowl.
Tip: Make the herb butter while your oven preheats for better time management.
- 4
Pat the halibut fillets dry with paper towels and season both sides generously with the remaining salt and pepper about 5 minutes before grilling.
Tip: Drying the fish prevents sticking and helps achieve better grill marks.
- 5
Lightly brush the grill grates with oil, then place halibut skin-side up on the grill. Cook for 5-6 minutes without moving.
Tip: Resist the urge to flip early; the skin will release naturally when ready.
- 6
Flip the halibut carefully and cook skin-side down for another 3-4 minutes until the flesh is opaque and flakes easily with a fork.
Tip: Halibut cooks quickly, so watch it closely to avoid overcooking.
- 7
In the final minute of cooking, place a sage leaf on top of each fillet and top with a generous dollop of herb butter, allowing it to melt over the fish.
Tip: The warm fish will melt the butter perfectly, creating a luxurious coating.

Transfer halibut to serving plates, squeeze fresh lemon juice over each fillet, and arrange roasted turnips alongside. Garnish with fresh thyme sprigs and remaining sage leaves.
Tip: Serve immediately while the fish and herb butter are warm for best flavor.
