Per inch of fish, the general rule is to allow 8-10 minutes of grill time. So, if your fish is two inches in thickness, grill each side for about six to eight minutes. But its always a good idea to check the instructions on your recipe.
How long and what temperature do you cook fish on the grill?
Cook the fish for 4 to 6 minutes and then turn to grill on the other side for approximately same amount of time. Insert the tip of a knife in thickest area of the fish to check for doneness. The meat should be flakey and opaque in appearance. The internal temperature of the fish should be at least 145°F.
Can I put fish directly on the grill?
Fish such as tuna, salmon, halibut, and swordfish, whose texture is more like beef or pork, should be grilled directly on the grate. (More delicate fish, such as tilapia, sole, and flounder, sometimes fare better when grilled in a foil packet or grill basket.)
What is the 10 minute rule for cooking fish?
Cook fish about 10 minutes per inch, turning it halfway through the cooking time. For example, a 1-inch fish steak should be cooked 5 minutes on each side for a total of 10 minutes. Pieces less than 1/2 inch thick do not have to be turned over.
