Bratwurst Sandwich Recipe

Simmer (optional, for juicier brats)

Place bratwurst in a skillet or saucepan. Add 1 cup beer or chicken broth and 1 tsp oil. Bring to a gentle simmer over medium heat, cover, and simmer for 8–10 minutes until internal temperature approaches 150°F (65°C). Remove brats and pat dry.

If skipping simmering, pat brats dry and proceed to sear: heat 2 tsp oil in a heavy skillet or grill pan over medium-high heat until shimmering.

Season the brats lightly with 1 tsp salt and 1/2 tsp black pepper. Place brats in the hot pan and sear, turning every 2–3 minutes, until well browned on all sides and internal temperature reaches 160°F (71°C), about 8–10 minutes total (longer if thicker). Remove and let rest 3 minutes.

While brats are simmering or resting, thinly slice the yellow onion and bell pepper into 1/4-inch strips.

Heat 1 tbsp butter or oil in a skillet over medium heat. Add the sliced onions and peppers, sprinkle with 1/4 tsp salt and 1/8 tsp black pepper, and cook, stirring occasionally, until soft and caramelized at the edges, about 8–10 minutes. Reduce heat if they begin to brown too quickly.

If you like, add 1–2 tbsp of the reserved simmering liquid or a splash of beer to deglaze the pan and intensify flavor; cook until liquid evaporates.

Split the rolls horizontally but keep one side attached if you prefer. Spread about 1 tsp Dijon mustard on the bottom half of each roll (or 4 tsp total divided).

Spread a thin layer of butter (about 1/2 tbsp per roll) on the outside cut faces of the rolls. Place rolls butter-side down in a clean skillet over medium heat or on a grill and toast until golden, 1–2 minutes per side. Remove from heat.

Place one seared brat in each roll. Top each brat with a generous portion of sautéed onions and peppers (divide evenly). Add about 1/4 cup sauerkraut or 2 tbsp pickles if using, distributing evenly among sandwiches.

Optional: Add a few drops of hot sauce and sprinkle 1 tsp chopped parsley over each sandwich for garnish. Close sandwiches and press slightly.

Serve immediately while hot. Provide extra mustard, pickles, or sauerkraut on the side. Leftover bratwurst can be refrigerated for up to 3 days and reheated gently.
