  • Total Time: 1 hour
  • Yield: Serves 2 sandwiches 1x

Ingredients

Scale
  • 4 slices sourdough bread
  • 6 tbsp unsalted butter, divided
  • 1 honeycrisp apple, thinly sliced
  • 2 large yellow onions, sliced
  • 8 oz cheddar cheese, grated
  • 2 oz brie cheese, sliced
  • 1 tbsp fresh sage, chopped
  • 2 tsp kosher salt
  • 1 tbsp olive oil

Instructions

  1. In a skillet over medium heat, melt 2 tablespoons of butter. Add sliced onions and sauté, stirring occasionally.
  2. After 10 minutes, sprinkle in 1 teaspoon of salt. Continue cooking for another 30-40 minutes until golden brown; add water if needed to prevent sticking.
