How do i cook fish in my oven if recipe calls for grilling?

As ChefOno says 'oven heat, then broil'.

Also, if this is a regular problem, there are stove-top pans you can buy that simulate grilling and work really well with fish.

Think of a broiler as an upside-down grill. Just be careful not to overheat / burn the glaze. You can regulate the amount of heat by adjusting the distance to the heating element.

Cooking by time = bad idea. Purchase a digital thermometer if you don't have one. You need 140F to kill possible parasites.

You can modify the straight grilling / broiling technique by allowing the glaze to get bubbly under the broiler and then switching to oven heat until the fish reaches a proper temperature. And you can do the reverse, oven heat until almost done, finish under the broiler which is probably what I would do for maximum control.

For fish, the cook time is generally 7-10 minutes per inch (thickness) of fish. Like half pint says, broiling is probably a great way to go, but the timing will likely depend more on the thickness of your fish than what the recipe directs.

Broil it for roughly the same amount of time.
