These Beer-Braised Brats with Quick Red Sauerkraut are the perfect tailgating food—you do most of the work ahead of time, and just heat the brats on the grill!
Heat the olive oil in a large skillet over medium high heat, add in the cabbage, red onion, and salt, and cook, stirring frequently, until the the cabbage wilts and is tender, about 10 minutes.
Add in the apple cider vinegar, and stir well (the acid in the vinegar will release the pink color of the cabbage and turn everything a solid purple). Continue to cook for 3-5 more minutes until the cabbage is very soft.
Meanwhile, pour the beer into a high-sided skillet. Heat over medium-high heat, then add in the brats. Cook, flipping every 2-3 minutes, until the brats are cooked through—about 15-20 minutes.
Refrigerate the brats and sauerkraut until ready to serve.
To serve: preheat a grill to medium-high heat. Place the brats on and cook for 3-5 minutes per side, just until browned and warmed through. Serve on hoagie buns with prepared red sauerkraut and grainy mustard.
