How to cook halibut without drying it out

Halibut is a delicious fish, with a very mild flavor and firm flesh. When cooked correctly, it is divine, but because it is low in fat, it can dry out easily. The most important rule to follow when cooking halibut is: Don’t overcook it. And the only way to know if your halibut is cooked is to use a thermometer. the USDA recommends cooking Halibut to an internal temperature of 145 degrees F. Using a thermometer will allow you to remove the halibut from the oven when it reaches this temperature to prevent it from over cooking and drying out.

How long to bake halibut in the oven at 425 degrees?

The baking time will depend on how thick the halibut filet is. It will take 10-15 minutes per 1 inch thickness of filet. Use an instant read thermometer to make sure fish is done and remove from oven when the internal temperature is 145 degrees F. The fish will also easily flake with a fork when done.
