A hearty and flavorful recipe featuring bratwurst sausages braised in beer with sweet caramelized onions, served on tangy mustard rolls. Perfect for casual gatherings and easy weeknight dinners.

Ingredients

Scale
  • 4 to 6 bratwurst sausages (pork or pork and veal mix)
  • 3 large yellow onions, thinly sliced
  • 12 ounces (355 ml) lager or pilsner beer
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon brown sugar
  • Salt and pepper to taste
  • 6 mustard rolls or soft buns
  • Dijon mustard for serving
  • Optional: fresh thyme or rosemary sprig
  • Optional: pickles or sauerkraut for topping

Instructions

  1. Peel and thinly slice 3 large yellow onions (about 5 minutes).
  2. Heat 2 tablespoons butter and 1 tablespoon olive oil over medium-low heat in a large skillet. Add onions and a pinch of salt. Stir every few minutes for 25-30 minutes until golden and soft.
  3. Stir in minced garlic and brown sugar, cooking for another 3 minutes until fragrant.
  4. Pierce the brats a couple of times with a fork to prevent bursting.
  5. Nestle the brats into the caramelized onions in the skillet. Pour 12 ounces of beer over them. Add a sprig of fresh thyme if using. Cover and simmer gently for 15-20 minutes, turning brats halfway through.
  6. Slice 6 rolls horizontally and brush insides lightly with Dijon mustard. Warm in a preheated oven at 350°F (175°C) for 5-7 minutes until toasty.
  7. Remove thyme sprig from skillet. Place brats on mustard rolls and top generously with caramelized onions. Serve with extra mustard, pickles, or sauerkraut on the side.

Notes

Caramelize onions low and slow to avoid burning. If onions brown too quickly, lower heat and add a splash of water to deglaze. Use a meat thermometer to ensure brats reach 160°F (71°C). For gluten-free, substitute rolls with gluten-free buns; for dairy-free, use olive oil instead of butter.
