Description

This Wisconsin beer brats recipe gently simmers fresh bratwurst with lager, butter, and onions before finishing the sausages on the grill for a browned casing and juicy center.


Ingredients

Units Scale
  • 6 fresh bratwurst, about 1 1/2 pounds (680 g)
  • 23 bottles lager or pilsner, 24-36 ounces (710 ml-1.06 L)
  • 2 large yellow onions, about 1 pound (450 g), thinly sliced
  • 2 tablespoons (28 g) unsalted butter
  • 6 brat rolls
  • 6 tablespoons (90 g) German mustard, or to taste
  • 1 1/2 cups (225 g) sauerkraut, drained

Instructions

  1. Build the beer bath. Put the bratwurst, thinly sliced onions, and butter into a 4-quart pot, then pour in enough lager to mostly cover the sausages. Don’t crowd them into a smaller pan because you want the hot liquid to move freely around every link as they cook.
  2. Simmer the bratwurst. Bring the beer slowly to a gentle simmer over medium heat, then lower the heat so you see small bubbles rather than a rolling boil. Cook for 10 to 15 minutes, turning the sausages once or twice while the onions soften. Hard boiling can be rough on the casings.
  3. Brown the brats. Transfer the sausages with tongs to a grill heated to medium, leaving the onions in the beer. Grill for about 2 to 3 minutes per side until the casings are deep golden-brown with darker grill marks. If they begin burning, move them immediately to a cooler part of the grill.
  4. Check for doneness. Insert an instant-read thermometer into the thickest part of a fresh brat and look for 160°F (71°C). If the center hasn’t reached that temperature, continue cooking over gentler heat and check again. Don’t keep grilling after they’re done, since extra cooking can dry the sausage.
  5. Finish and serve. Let the beer onions continue simmering until very soft, then drain them well so they won’t soak the rolls. Place each brat in a roll and spoon the warm onions over it. Add German mustard and sauerkraut, then serve while the sausage casing is still hot and firm.

Notes

  1. Don’t pierce the bratwurst with a fork while cooking because holes allow the juices and melted fat inside the casing to escape.
  2. Keep the beer at a gentle simmer rather than a rolling boil so the sausages cook in controlled heat.
  3. Fresh bratwurst should reach 160°F (71°C) in the center before it’s served.
  4. For stovetop brats, brown them for about 3 minutes on each of two sides, add ½ cup (120 ml) liquid, cover, and cook over low heat for about 10 minutes or until done.
  5. For oven brats, bake at 425°F (220°C) for about 13 to 18 minutes, turning once and checking the internal temperature before serving.
  6. For air fryer brats, cook at 360°F (182°C) for 12 to 15 minutes and turn halfway through; fully cooked brats generally need less time.
