Instructions

Step 1: Heat 1 tbsp olive oil and 2 tbsp unsalted butter in a large skillet over medium heat. Add 2 thinly sliced yellow onions, 1 tsp salt, 1/2 tsp black pepper, and 1 tbsp brown sugar. Cook for 20-25 minutes, stirring occasionally, until onions are deeply golden and caramelized. Remove onions and set aside.
Step 2: Using the same skillet, melt remaining 1 tbsp butter over medium heat. Add 6 bratwurst sausages and brown them for 3 minutes on each side until golden.
Step 3: Pour in 12 oz craft beer, making sure the sausages are partially submerged. Bring to a simmer, cover, and braise for 15 minutes until sausages are cooked through.
Step 4: Remove bratwursts from beer and place in toasted 6 hoagie buns. Top each with a generous spoonful of caramelized onions and 1 tbsp Dijon mustard. Serve warm.
