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.
Bring the liquid to a simmer but not a full boil, as this could cause the sausage to split. Cook them for about 15 minutes, turning often to expose all sides to the cooking liquid. Cook until the liquid has been reduced and the bratwurst starts to stick to the pan. Remove the sausage to a platter and cook any seasoning vegetables in the hot drippings until tender and slightly browned.
