Instructions

Step 1: Place 6 bratwurst sausages in a shallow dish and pour 1 cup lager beer over them. Cover and marinate in the refrigerator for at least 2 hours, turning occasionally.
Step 2: While sausages marinate, melt 2 tbsp unsalted butter and heat 1 tbsp olive oil in a large skillet over medium heat. Add 2 thinly sliced yellow onions, 1 tbsp brown sugar, 1 tsp salt, and 1/2 tsp black pepper. Cook, stirring occasionally, for 20-25 minutes until onions are deep golden and caramelized.
Step 3: Preheat a grill to medium-high heat. Remove bratwurst from the beer marinade, discard the liquid, and grill sausages for 6-8 minutes per side until browned and cooked through.
Step 4: Serve each grilled bratwurst in a toasted hoagie roll, topped generously with the caramelized onions and sprinkled with 2 tbsp chopped fresh parsley.
