Move the racks inside your oven so one of them is in the center position, or else your fish won’t cook as thoroughly. Turn your oven on to 450 °F (232 °C) and let it heat up completely before cooking. Place the foil directly on the center oven rack or on a cooking pan so it can cook. Leave the fish alone inside of the oven for at least 15 minutes before checking if it’s done. Check if the meat is white and flaky, and use a meat thermometer to see if it has an internal temperature of 145 °F (63 °C). The cooking time may vary depending on the size and thickness of your filets. Once the fish is finished cooking, put the foil wrap directly on a serving plate so you can open it just before you eat. Squeeze a fresh lemon wedge on top of the filet to add a fresh citrus flavor to your meal. You can keep tilapia leftovers for 4 days in the fridge or up to 3 months in the freezer.
