Ingredients

Instructions

  1. Step 1: Heat 1 tbsp olive oil in a skillet over medium heat. Add 1 large thinly sliced yellow onion with 1 tbsp brown sugar, 1/4 tsp salt, and 1/4 tsp black pepper. Cook for 15 minutes, stirring occasionally, until onions are deeply caramelized.
  2. Step 2: Butter one side of each of 4 slices of sourdough bread with 4 tbsp unsalted butter divided evenly.
  3. Step 3: Place two bread slices butter-side down on a clean skillet over medium heat. Layer each with 4 oz sliced Gouda cheese, half the caramelized onions, and thinly sliced half of 1 medium Granny Smith apple.
  4. Step 4: Top with the remaining bread slices, butter-side up. Cook sandwiches for 4-5 minutes per side, pressing gently with a spatula, until bread is golden brown and cheese melts.
  5. Step 5: Remove from heat, let cool 1 minute, then slice and serve warm.
