Why I Love This Recipe

  • 🍺 Beer braising adds depth and a malty richness that infuses the brats
  • 🧅 Caramelized onions offer a natural sweetness and silky texture
  • 🥘 Oven-braised = low effort, perfect for busy nights or relaxed weekends
  • 🥖 Endlessly pairable with buns, mashed potatoes, sauerkraut, or a crusty loaf

Ingredients

  • 6 bratwurst sausages
  • 2 large onions, thinly sliced
  • 1 tablespoon olive oil
  • 1 tablespoon unsalted butter
  • 1 teaspoon sugar
  • 1 teaspoon salt
  • 12 oz beer (lager or ale works best)
  • 2 teaspoons Dijon mustard
  • Fresh thyme or parsley, for garnish

Instructions

1. Preheat & Prep

Preheat your oven to 375°F (190°C).

2. Caramelize the Onions

In a large ovenproof skillet or Dutch oven, heat the olive oil and butter over medium heat. Add onionssugar, and salt. Cook, stirring occasionally, until onions are deeply golden and soft—about 15–20 minutes.

3. Brown the Brats

Push the onions to the edges of the skillet and place the bratwursts in the center. Brown them for 2–3 minutes per side, just to sear.

4. Braise in Beer

Pour in the beer and stir in Dijon mustard. Spoon some onions over the sausages.

5. Oven Time

Transfer the skillet to your preheated oven and braise uncovered for 30–35 minutes, turning sausages once halfway through. The beer will reduce to a flavorful glaze, coating the brats and onions.

6. Garnish & Serve

Remove from the oven, top with fresh thyme or parsley, and serve hot.


Tips for Success

  • Use a lager or amber ale for balanced flavor—not too hoppy, not too light
  • Add a splash of apple cider vinegar at the end for brightness
  • Pair with spicy mustard or grainy Dijon on the side
  • Swap brats for Italian sausages if desired

Serving Suggestions

These brats are incredibly versatile. Try them with:


Storage & Leftovers

  • Fridge: Store in an airtight container for up to 4 days
  • Reheat: Simmer in a skillet over medium heat or microwave gently
  • Freezer: Brats can be frozen for up to 2 months; onions don’t freeze well solo

Final Thoughts

This Oven Braised Beer Brats with Caramelized Onions recipe is everything a comfort meal should be: rich, savory, and wildly satisfying. Serve it up for a casual dinner, game day spread, or Oktoberfest-inspired feast and watch it disappear fast.
