This is one of my favorite weeknight dinners because it comes together in under an hour and feels fancy enough to impress guests. Halibut is a lean protein packed with omega 3 fatty acids, which are wonderful for heart health, and the fish gets beautifully flaky when grilled. What I love most is the simplicity of it all: you just need quality ingredients and good timing. The charred brussels sprouts add a wonderful caramelized sweetness that plays perfectly against the bright lemon butter sauce. Trust me, this elegant meal is far easier than it looks.

Instructions
- 1
Preheat grill to medium-high heat (about 400°F). Pat halibut fillets dry with paper towels and season both sides with half the salt and pepper.
Tip: Dry fish prevents sticking and ensures better browning on the grill.

In a large bowl, toss brussels sprouts with 2 tablespoons olive oil, remaining salt, and pepper. Arrange cut-side down on grill grates and cook for 8-10 minutes until golden, then flip and cook 5 more minutes until tender and charred.
Tip: Cutting brussels sprouts in half exposes flat surfaces for maximum caramelization.

While brussels sprouts finish cooking, brush halibut fillets on both sides with remaining 2 tablespoons olive oil. Place skin-side up on a clean section of grill.
Tip: Keep skin-side up first to prevent sticking on the initial contact.
- 4
Grill halibut for 4-5 minutes without moving, then gently flip and cook another 3-4 minutes until the flesh is opaque and flakes easily with a fork.
Tip: Halibut cooks quickly; avoid overcooking to maintain moisture and delicate flavor.
- 5
While fish cooks, melt butter in a small saucepan over medium heat. Add minced garlic and cook for 1 minute until fragrant, then remove from heat and stir in lemon zest, lemon juice, and red pepper flakes.
Tip: Remove butter from heat before adding lemon juice to prevent the sauce from becoming too sharp.
- 6
Transfer halibut and brussels sprouts to serving plates. Drizzle lemon butter sauce over the fish and sprouts, then garnish with fresh parsley and fresh thyme leaves.
Tip: Serve immediately while the fish is still warm and flaky for best texture and presentation.
