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.
Polish sausage (or Kielbasa) is usually fully cooked. Look on the package. You just heat that up. If you have some other product similar to a bratwurst then you can bake it at 375 for 20 to 30 minutes. Or microwave it. I like to brown my in skillet or grill it.
