Ingredients Breakdown
Essentials
- 4 bratwurst sausages
- 4 sturdy buns (pretzel or brioche work beautifully)
- 2 large yellow onions, thinly sliced
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 teaspoon brown sugar
- Salt and pepper to taste
- Optional: mustard, sauerkraut, or pickles for topping
Pro Tips
- Use sweet onions for an extra depth of flavor when caramelizing.
- Pretzel buns hold up really well and add a salty bite.
- Try beer-brats if you want a heartier, maltier flavor—just simmer in beer before grilling.
- Have a warm grill-ready area and a cooler zone to finish brats without over-charring.
Step-by-Step Instructions
- Preheat your grill to medium heat (about 375°F).
- In a large skillet over medium-low heat, melt butter and olive oil together. Add sliced onions and cook, stirring occasionally, for about 25–30 minutes until deep golden and caramelized. Add the brown sugar halfway through and a pinch of salt toward the end.
- While onions cook, place brats on the grill. Grill for about 15–18 minutes, turning frequently until they’re browned all over and cooked through (internal temp should be 160°F).
- Optional: Toast your buns on the grill for 1–2 minutes for that perfect crunch.
- To serve, place each brat into a bun, top generously with caramelized onions, and finish with your favorite toppings.
Chef’s Tips and Tricks
- Don’t rush the onions—low and slow is the name of the game for that perfect sweetness.
- Score your brats lightly with a knife before grilling to release juices and promote even cooking.
- If you need to make these ahead, keep the caramelized onions warm in a slow cooker on low.
- Let the grill preheat fully before adding the brats—it’ll help with even browning and gorgeous grill marks.
Recipe Variations and Serving Suggestions
- Swap classic brats for chicken or veggie sausages.
- Add melted Swiss or aged cheddar for a cheesy twist.
- Serve with German potato salad or grilled corn on the cob for the ultimate summer plate.
- Top with beer mustard, pickled jalapeños, or even crispy shallots for extra flair.
- Slice brats and stuff into sliders or mini buns for a cute party-friendly version.
