Bratwurst are a tailgating staple in the Midwest, particularly in Wisconsin. These brats are simmered with onions in a Midwestern brewed beer before being finished on the grill and dressed with a spicy mustard sauce.
You only need a few basic ingredients for this recipe (see above). The choice of beer and mustard is yours.
Pour three bottles of beer in a heavy duty aluminum pan or sauce pot. Add two sliced onions and bring to a boil.
Reduce heat to medium/low and add the brats to the beer. Simmer the brats for 15 minutes. Make sure that the water is not hot enough to boil while the brats are simmering. The natural casings will split if the water is too hot.
Finish the brats on the grill for 10-12 minutes on medium heat. At this point, the brats are fully cooked. They can be served immediately or returned to the beer bath to be kept warm.
There are plenty of options for topping these brats, but I like to keep it basic. I topped my brat with the beer soaked onions and spicy brown mustard.
