How Long To Bake Halibut In Oven At 350 Degrees?

Baking halibut at 350 degrees in the oven would normally take around 20-25 minutes. However, you can remove the fish from the oven earlier when the meat flakes easily with a fork. You can also actually raise the temperature to 400 degrees which would only take around 15 minutes for the halibut to cook. But, you have to be careful and be more attentive not to overcook it since overcooked halibut is dry halibut and no one wants that. To be safe and to cook your halibut just right,  350 degrees would be your magic number! Another key is to make sure that your fish’s internal temperature is on the right mark! For halibut, it’s best to cook them only to an internal temperature of 130-135 degrees. Anything higher than that would mean that your fish has dried out. So, for a perfect halibut dinner, remember, 350 degrees in oven and a 135 degrees internal temp for the halibut fish!

Just thinking about halibut makes my mouth water already. I’m pretty sure everyone who’s invited to your halibut dinner can’t wait for dinner to be served on their plates. And if you’re thinking of serving your fish faster, here are ways you can do so.

Add some fat

One of the reasons why we brush the fish with oil or butter is because oil and butter are heat conductors. This just means that they absorb heat, and the more generous amount of oil you put in your fish, the faster it can cook. Oil and butter can also help lessen the tendency of your fish to dry. Don’t go overboard though, too much oil or butter isn’t good too.

Thaw your halibut Fish

Hours before you cook, make sure that you have removed your halibut fish from the fridge already! This will allow the fish to cook more evenly and faster. So, make sure to give your fish enough time to thaw and defrost!
