Ingredients

Instructions

  1. Step 1: In a large skillet over medium heat, melt 3 tbsp unsalted butter and 1 tbsp olive oil. Add 2 thinly sliced yellow onions and 1 tsp salt, cooking gently for 20-25 minutes, stirring occasionally, until the onions turn golden brown and caramelized.
  2. Step 2: In a separate large saucepan, pour 12 oz lager beer and bring to a simmer over medium heat. Add 6 bratwurst sausages and simmer gently for 15 minutes until cooked through and plump.
  3. Step 3: Preheat a grill pan or cast iron skillet to medium-high heat. Remove the bratwursts from the beer bath, pat dry, and sear for 2-3 minutes per side until browned and slightly crisp.
  4. Step 4: Toast 6 hoagie rolls lightly on the grill or in a toaster.
  5. Step 5: Assemble by placing one bratwurst in each roll, topping with caramelized onions, 2 tbsp dijon mustard evenly divided, and 1/6 cup sauerkraut if using. Serve immediately.
