Instructions

Step 1: Heat 2 tbsp butter and 1 tbsp olive oil in a skillet over medium heat. Add 1 small thinly sliced yellow onion with 1 tsp brown sugar, 1/4 tsp salt, and 1/8 tsp black pepper. Cook, stirring frequently, for 15 minutes until onions are deeply caramelized and soft.
Step 2: Remove onions and wipe skillet clean. Butter one side of each of the 4 sourdough bread slices with the remaining 1 tbsp butter.
Step 3: Place two slices butter-side-down in the skillet over medium heat. Layer 4 oz aged cheddar cheese, half the caramelized onions, and half the thinly sliced Granny Smith apple on each slice. Top with the remaining bread slices, butter-side-up.
Step 4: Cook sandwiches for 4-5 minutes per side, pressing gently with a spatula, until bread is golden brown and cheese is melted.
Step 5: Remove from heat, slice in half, and serve warm.
