Herb-Crusted Baked Halibut Steaks

Why This Herb-Crusted Baked Halibut Steaks Works

In the oven, the halibut cooks gently while the panko and Parmesan on top dry out and crisp up. As the fish heats, it gives off a bit of moisture. Instead of that moisture escaping into the oven and drying the fish, a lot of it rises into the crumb layer. The panko soaks some of it up, so the crumbs stay crunchy on the outside but a little soft underneath, like a thin protective blanket.

At the same time, the olive oil coats the crumbs and cheese, so they brown instead of burning. That light crust shields the halibut from the direct heat, so the inside stays moist and flaky instead of tough. Lemon zest, parsley, dill, and garlic powder are all trapped in that crust, so as it warms up, their taste spreads down into the top of the fish. By the time the crust is golden, the halibut is just cooked through and still juicy, and a squeeze of lemon wakes everything up right at the end.

Mistakes To Avoid

Letting the halibut bake too long easily dries it out. The fish turns from moist and flaky to stiff and chalky, and the herb crust goes from crisp to hard and slightly burnt around the edges.

Putting the herb crust on wet fish causes another problem. Excess moisture on the halibut makes the breadcrumb mix slide around and steam instead of toasting, so the crust turns soft and patchy instead of forming a firm, golden layer.

Packing the crust on in a very thick layer can also backfire. The top browns slowly while the bottom of the crumb layer stays a bit soggy and pasty, and the fish underneath can overcook by the time the surface looks nicely colored.

Using very little oil in the crumb mixture leaves the topping dry and dusty. The panko doesn’t really toast, the cheese doesn’t melt into the crumbs, and the crust tends to fall off in chunks when the steaks are served.
