This baked miso halibut features tender halibut fillets coated in a savory-sweet ginger miso glaze made with white miso, honey, soy sauce, and fresh ginger. The fish marinates briefly, then bakes until flaky and moist with a glossy glaze and a touch of chili heat.
In a small bowl, whisk together the miso, honey, soy sauce, lime juice (or rice vinegar), grated ginger, and chili garlic sauce until smooth.
Place the halibut fillets in a shallow dish or a sealable bag and marinate in the refrigerator for 30 minutes.
To Bake the Halibut:
Heat the oven to 400°F.
Remove the halibut from the marinade and place it on a parchment-lined rimmed baking sheet. Spoon any remaining glaze over the fillets.
Bake for 14 to 18 minutes, depending on the thickness of the fillets, until the fish flakes easily with a fork and is opaque throughout.
Notes
Adjust bake time as needed: Thick center-cut halibut fillets may take longer than thinner tail pieces.Check for doneness: Insert a fork into the thickest part of the fish at an angle and twist gently. The fish should flake easily and appear opaque.Internal temperature: We prefer halibut cooked to 135°F. The USDA recommends 145°F. Carryover heat will continue cooking the fish for a few minutes after it comes out of the oven.Customize the heat: One teaspoon of chili oil adds mild warmth. Use two teaspoons for a more noticeable kick.Fresh ginger makes a difference: Freshly grated ginger adds a bright flavor that balances the savory miso and sweet honey glaze. Ground ginger won't provide the same flavor.Use a thermometer if you have one: Halibut can go from moist and flaky to dry pretty quickly. I like to pull it from the oven when the thickest part reaches 130°F to 135°F and let carryover heat finish the job while it rests.
