This is one of my favorite weeknight dinners because it comes together in just over an hour and tastes like you've spent all day cooking. Halibut is such a lean, delicate fish that pairs beautifully with the warm, nutty flavors of roasted butternut squash and sage brown butter. What I love most is that halibut is packed with omega 3 fatty acids, which are wonderful for your heart and brain. The best part? Everything cooks on one sheet, so cleanup is minimal. Trust me, once you try this combination, you'll find yourself making it again and again.

Instructions
- 1
Preheat your grill to medium-high heat and oil the grates well. Toss butternut squash cubes with 2 tablespoons olive oil, half the salt, and pepper. Spread on a sheet pan.
Tip: Pre-roasting the squash ensures it's tender while the halibut cooks on the grill.
- 2
Roast the squash in a 400°F oven for 20-25 minutes, stirring halfway through, until golden and fork-tender.
- 3
While squash roasts, pat halibut fillets dry and brush both sides with remaining olive oil. Season generously with salt, pepper, and lemon zest. Place a thyme sprig on top of each fillet.
Tip: Dry fish prevents sticking to the grill and ensures better browning.
- 4
Once squash is nearly done, place halibut skin-side up on the grill. Cook for 4-5 minutes without moving, then gently flip and cook another 3-4 minutes until flesh is opaque and flakes easily.
Tip: Don't flip too early; let it develop a nice crust for better flavor.
- 5
While halibut finishes cooking, melt butter in a small skillet over medium heat. Add minced garlic and sliced shallot, cooking for 2 minutes until fragrant.
- 6
Add sage leaves to the butter and continue cooking, swirling occasionally, until the butter turns golden brown and smells nutty, about 3-4 minutes. Deglaze with vegetable broth and squeeze in lemon juice.
Tip: Watch the butter carefully to prevent burning; brown butter transforms quickly.
- 7
Remove halibut from grill and transfer to serving plates. Arrange roasted butternut squash alongside each fillet.
- 8
Spoon the warm sage brown butter sauce over the halibut and squash, garnishing with fresh thyme and remaining lemon zest before serving.
Tip: Serve immediately while the butter sauce is warm for best flavor.
