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.
A great basic bratwurst recipe such as our How to Cook Brats in Beer guide provides more details but here are the basics, as far as how long to boil brats. Youâll add your brats to a pot or large skillet and add equal parts liquid â either water and beer or just water â until the brats are covered by liquid. Bring them to a brisk boil but then immediately turn down the heat to a very low boil, more of a simmer than an active boil. Simmer your brats for about 15 to 20 minutes, then finish off on the grill or in a pan with just your brats and a little olive oil to get a nice crispy char and finish.
