Equipment

  • Smoker or pellet grill Set up for indirect heat at 225 degrees F or 250 degrees F
  • Instant-read meat thermometer For checking the 160 degrees F internal temperature
  • Cast iron skillet For cooking the beer onions
  • Tongs For turning and removing the brats

Ingredients
  

For the Smoked Brats

  • 5 links fresh uncooked bratwurst pork, beef, or cheese-stuffed brats
  • 1 batch apple, cherry, or hickory wood pellets or chunks use your preferred smoker fuel

For the Beer Onions

  • 2 tablespoons butter for sauteing the onions
  • 2 large yellow onions sliced into thin half-rings
  • 12 ounces lager or pilsner one standard bottle or can
  • 1/2 teaspoon kosher salt plus more to taste
  • 1/4 teaspoon black pepper freshly ground if possible

For Serving

  • 5 bakery-style buns brioche or pretzel buns work well
  • 5 tablespoons stone-ground or spicy brown mustard or to taste

Instructions
 

  • Preheat your smoker or pellet grill to 225 degrees F for the deepest smoke flavor. For a faster cook, set it to 250 degrees F.
  • Place the fresh uncooked brats directly on the smoker grates over indirect heat, leaving space between each link so smoke can circulate.
  • Smoke the brats for 90 minutes at 225 degrees F, or about 75 minutes at 250 degrees F, turning once halfway through for even color.
  • While the brats smoke, melt the butter in a cast-iron skillet over medium heat. Add the sliced onions and cook for 10 minutes, stirring occasionally, until softened.
  • Pour in the beer, reduce the heat to low, and simmer for 15 minutes until the beer reduces and the onions are tender and caramelized. Season with salt and pepper.
  • Check the thickest part of each brat with an instant-read thermometer. Remove the brats from the smoker when they reach 160 degrees F internal temperature.
  • Rest the brats for 5 minutes. Toast the buns briefly, then serve each brat with warm beer onions and mustard.

Notes

Use fresh uncooked brats for best smoke absorption. Pre-cooked brats can dry out because they have already been heated through before smoking.
Always cook bratwurst to 160 degrees F internal temperature because it is a ground sausage.
