Add the beer, water, onion and brats to a large pot and bring to a boil.
12 oz beer, 12 oz water, 1 onion, 6 brats
Reduce heat to a simmer and cook for 15 minutes.
Preheat grill to 450°F.
Remove brats from beer and grill for 15 minutes, turning after 7 minutes to brown evenly.
While brats are grilling, remove onions from the beer mixture. Heat 1 tablespoon of olive oil in a small pan and sauté onions for 10 minutes or until golden brown. Set aside until ready to serve.
1 tablespoon olive oil
Brush buns with melted butter and place on top rack of grill for 30-60 seconds to brown. Watch carefully so they don't burn.
brat buns, 1 tablespoon melted butter
Remove brats from the grill and serve immediately with sautéed onions, buns and condiments.
Brats - We love to use fresh bratwurst. You can also use cheddar brats, chicken brats or beer brats.
Onions - Sweet onions add great flavor when they are cooked but you can also use yellow or white if that is all you have on hand.
Beer - Any kind of beer can be used for this recipe.
Buns- Brioche buns are dense and hold the brats and sauerkraut well without tearing.
Grilling Notes:Brats are considered safe to eat when they have been cooked to 160°F. Simmering the brats actually parcooks them so they need less time on the grill (and are less likely to be undercooked when the outside is perfectly golden).
