Braising brats in beer and onions deepens the flavor of the bratwurst. After simmering in the onions and beer the brats are grilled quickly for nicely browned casings. The brats can then be finished with the richly flavored caramelized onions, placed on lightly grilled buns and topped with your favorite fixings. Pure dinnertime bliss!
Print Recipe



  • 2 12 ounce cans pilsner beer 12 ounces each
  • 2 onions halved and sliced ¼-inch thick
  • 6 uncooked bratwurst
  • 6 brat buns split


  • Preheat a gas grill or charcoal grill to medium heat.
  • Place a cast iron skillet on the grill grates and add the oil and butter. Heat until the butter is melted, swirling the skillet to coat. Add the onions and cook, stirring occasionally, 7 to 10 minutes or until just softened. Pour in the beer and heat until simmering. Add the bratwurst to the skillet and nestle the brats in the onions.
  • Close the lid of the grill and cook, turning the brats often, for 20 minutes or until the onions are caramelized, the bratwurst is lightly brown and an instant read thermometer inserted into center of the brats registers 160°F.
  • Using tongs, transfer bratwurst to the the grill grates and grill, turning often, 3 to 5 minutes or until they are browned on all sides. Continue simmering the onions in the skillet, stirring often, 5 to 7 minutes or until the liquid has cooked off and the onions are caramelized.
  • Meanwhile, grill the buns, cut-side down, 1 minute or until golden.
  • Using tongs, transfer the brats to a serving plate and let rest a few minutes until ready to serve. Serve the brats with the onions and buns alongside.

Optional Condiments

  • Serve with ketchup, mustard, prepared horseradish, chopped raw onions, sautéed bell peppers, or pickles alongside the bratwurst.


Use tongs when handling the bratwurst. Silicone coated tongs are the best for this. You do not want to pierce the skin on the brats.
Make sure to purchase uncooked (raw) bratwurst for this recipe.
Any flavor or type of bratwurst that you like will work for this recipe. I personally prefer plain bratwurst to start and then I can add other ingredients as I prefer.
Do not increase the heat of your grill higher than medium or you risk splitting the bratwurst open.
