Put your uncooked brats on a broiler pan and pop them in the oven, cooking them for about five minutes at a time on each side. Keep turning them until they brown up nicely and are good to go. This should take 15-20 minutes for uncooked brats and just 5-10 minutes for precooked bratwurst.
Next, allow the beef to simmer on an uncovered grill for approximately 15 minutes over medium coals or medium heat on a gas grill. Itâs important to turn the bratwurst over once during this period. After 15 minutes or so, remove the bratwurst from the saucepan. The final thing to do is to grill the bratwurst directly over the grillâs heat until it has turned brown and is cooked through, which usually takes about 10 minutes. You should turn the bratwurst approximately halfway into the grilling time.
