Tilapia is especially fitted for grilling because it doesn't flake easily or fall apart on a grill. It is firm yet tender and grilling gives it a mild and delicate flavor. You can use just about any sauce or seasoning for tilapia before grilling it. Some decide to go with basic salt and pepper while others prefer cayenne pepper and marinades. Tilapia takes only a little time to grill, and requires no experience to cook. As long as you prepare the fish well for grilling, your grilled tilapia will come out great.
Choose a tilapia fillet that is no more than 1-in. thick to achieve even doneness.
Bring the fillet out of the refrigerator, and thaw at room temperature.
Rub the 1/2 tsp. oil on both sides of the fillet. Sprinkle with salt and pepper or your favorite marinade or sauce for seasoning. Keep in marinade for no longer than 30 minutes if you prefer marinating.
Prepare the grill by covering where the tilapia will be placed with a non-stick cooking spray. Use a raised basket or tray if you want to keep the tilapia from direct heat.
Grill the tilapia over medium heat, and make sure the flame does not touch the fish. Cook for 5 or 10 min. if grilling with indirect heat. Flip over the tilapia once while grilling with a metal spatula. Turn off the grill when the fillet becomes whitened, flaky and oozes clear juice.
