01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly grease a baking dish.
02 - Pat the halibut fillets dry with paper towels. Brush both sides with olive oil and season with salt and freshly ground black pepper.
03 - In a small bowl, combine softened butter, minced garlic, chopped parsley, dill, thyme leaves, lemon zest, and lemon juice. Mix until fully incorporated.
04 - Place halibut fillets onto the prepared baking sheet. Evenly spread a generous spoonful of the lemon herb butter atop each fillet.
05 - Bake for 12 to 15 minutes, or until fish flakes easily with a fork and appears opaque throughout.
06 - Remove from oven and let rest for 2 minutes to allow flavors to settle.
07 - Serve immediately, garnished with lemon wedges and additional chopped parsley if desired.
