Beer-Braised Brats with Caramelized Onions & Chives
This beer brats recipe grills the bratwursts first for char, then braises them in lager with butter-caramelized sweet onions and spicy brown mustard until juicy. Served on toasted buns with beer-braised onions and fresh chives.
Equipment
- Gas Grill (two-zone setup)
- Cast Iron Skillet
- Instant-Read Thermometer
- Tongs
Ingredients
Brats
- 6 bratwursts
- 6 toasted sub or brat buns
- 2 bottles lager beer 12 oz each
Beer-Braised Onions
- 2 large sweet onions, thinly sliced
- 2 tbsp unsalted butter
- 1 tbsp brown sugar
- 1 tsp coarse black pepper
- 2 tbsp spicy brown mustard
For Serving
- additional spicy brown mustard
- 2 tbsp fresh chives, finely chopped
Instructions
- Preheat the gas grill to medium heat, around 350-400°F. Set up one side for direct cooking and place a cast iron skillet over the other side.
- Add the butter to the cast iron skillet. Once melted, add the sliced onions, brown sugar, and black pepper. Cook 15-20 minutes, stirring occasionally, until softened and golden brown.
- Place the bratwursts directly over medium heat. Cook 8-10 minutes, rotating every few minutes, until evenly browned with grill marks.
- Pour both bottles of lager into the skillet with the onions. Stir in 2 tablespoons of spicy brown mustard and bring to a gentle simmer.
- Transfer the grilled brats into the beer and onion mixture. Close the lid and cook another 15-20 minutes, until the brats reach 165°F internal.
- While the brats finish braising, lightly toast the buns directly on the grill for 30-60 seconds.
- Spread spicy brown mustard onto each toasted bun. Add a brat, top generously with beer-braised onions, and finish with fresh chopped chives. Serve immediately.
Notes
Grill First, Braise Second: The char and caramelization create flavor you can't get by simmering alone.
Use a Lager: Lighter lagers produce a smoother flavor than hoppy IPAs, which turn bitter when cooked.
Don't Rush the Onions: Give them the full 15-20 minutes to caramelize before adding the beer.
Toast the Buns: A toasted bun adds texture and prevents sogginess from the beer-braised onions.
Finish with Chives: Fresh chives add brightness and color. Not sponsored — the beer and equipment are simply what James used.
