Sheet Pan Roasted Halibut

Halibut is a close second to salmon when it comes to my favorite fish. It has a mild, sweet flavor similar to cod but a bit firmer in texture, yet flaky and tender.

Halibut is incredibly versatile. It can be roasted, broiled, grilled, fried, sautéed, and poached. A note of caution, however, it’s a lean fish with little oil so it can overcook quickly.

In this recipe, we pour a blend of olive oil and sesame oil with lemon juice and zest over the fish and vegetables. The coating not only adds flavor, it helps keep the halibut moist when roasting.

Try to buy fillets 1 – 1 ½ inches thick. When I’ve ended up with fillets of varying thickness, I’ll give the thicker ones a 3-minute head start in a separate baking pan. This way the thinner fillets and vegetables don’t overcook.

The halibut should be opaque in the center and flake when done. The mushrooms will be soft, and the green beans crisp tender. Our Cilantro Pistachio Pesto completes the dish.  Enjoy!!
