Answer Wiki. First off, one does NOT boil bratwurst. One gently simmers bratwurst in a lager or pilsner beer with plenty of julienned yellow onions for about 10-15 minutes. The brats are then grilled over charcoal until uniformly brown, put in brat buns along with some of the onions and some good brown mustard.
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.
