Instructions

  1. Step 1: In a large skillet over medium heat, melt 3 tbsp unsalted butter with 1 tbsp olive oil. Add 2 thinly sliced large yellow onions and 1 tbsp brown sugar, cooking for 20-25 minutes stirring frequently until the onions are deeply golden and caramelized.
  2. Step 2: Push the onions to the side and add 6 bratwurst sausages to the skillet. Brown the sausages for 3-4 minutes per side until golden.
  3. Step 3: Pour in 2 cups Belgian amber beer, season with 1 tsp salt and 1/2 tsp black pepper, and bring to a simmer. Cover and let the bratwurst braise gently for 15 minutes until cooked through and tender.
  4. Step 4: Remove bratwurst and onions to a serving platter. Stir 1/4 cup Dijon mustard into the cooking liquid to create a tangy sauce, simmering for 2 minutes until slightly thickened.
  5. Step 5: Serve the bratwurst topped with caramelized onions and drizzled with the mustard sauce, garnished with 2 tbsp chopped fresh parsley.
