Do you need to boil potatoes before roasting them with halibut?

Parboiling potatoes for 5 to 7 minutes before roasting helps achieve a crispier texture and allows them to cook perfectly alongside halibut. Smaller potato pieces may not require parboiling, as they can cook fully within the roasting time of the fish.

What is the best fish to use if I don't have halibut?

Firm-fleshed white fish such as cod, haddock, or bass make good substitutes. It’s important the fish is similar in thickness to halibut to ensure even cooking during baking.

How long do you roast halibut and potatoes together?

Roast potatoes for about 15 to 20 minutes before adding halibut and green beans, then roast everything together for an additional 15 to 20 minutes. The fish is done when opaque and flakes easily, and potatoes should be golden and tender.

What seasonings enhance the flavor of baked halibut and potatoes?

A combination of garlic, Italian seasoning, kosher salt, black pepper, lemon zest, and fresh lemon juice works well. Fresh herbs like rosemary or parsley and a pinch of red pepper flakes can add variety and aromatic depth.
