The best and the easiest way to cook halibut is by baking it in the oven. Only one pan is used (baking sheet). In this recipe, both halibut and asparagus are crusted with garlic and freshly shredded Parmesan cheese, which adds wonderful flavor and a crunch to the dish.

Halibut is a lean fish with a firm yet soft texture and a mild taste. Because it is a lean fish, it is easy to overcook as it dries out faster. Tip: Serve it immediately after cooking to prevent halibut from drying out. Do not let the baked halibut sit on the counter. Do not reheat it in the microwave. Make sure the halibut is served right after it’s cooked.

Cooking Tips

You don’t have to skin the halibut since it cooks better and keeps its shape better with the skin on one side. Once cooked, the skin can be removed easily from the fish.
Use fresh halibut, preferably never frozen.
Line baking sheet with parchment paper to minimize cleanup.
Serve immediately after baking for best halibut texture. The longer the halibut sits, the drier it becomes. Do not reheat in microwave.
