Gourmet sandwich layered with caramelized onions, crisp apple slices, and sharp cheddar cheese on buttery bread.
# What You'll Need:
→ Caramelized Onions
01 - 1 large yellow onion, thinly sliced
02 - 1 tablespoon unsalted butter
03 - 1 teaspoon olive oil
04 - 1/2 teaspoon salt
05 - 1/2 teaspoon sugar (optional)
→ Sandwich
06 - 4 slices sourdough or country bread
07 - 2 tablespoons unsalted butter, softened (for spreading)
08 - 1 medium crisp apple (Granny Smith or Honeycrisp), thinly sliced
09 - 4 ounces sharp cheddar cheese, sliced or shredded
10 - Freshly ground black pepper, to taste
# Step-by-Step Guide:
01 - In a skillet over medium-low heat, melt 1 tablespoon unsalted butter with olive oil. Add thinly sliced onion and salt. Stir frequently and cook for 15 to 18 minutes until onions turn golden brown and soft. Optionally add sugar halfway through cooking for added sweetness. Remove from heat and set aside.
02 - Lay the bread slices on a clean surface. Spread softened butter on one side of each slice. On the unbuttered side, layer half the cheddar cheese, followed by caramelized onions, apple slices, a pinch of black pepper, then the remaining cheddar. Top with the second slice of bread, buttered side facing out.
03 - Preheat a nonstick skillet or griddle over medium heat. Place the assembled sandwiches in the skillet and cook for 3 to 4 minutes per side, pressing gently, until the bread is golden brown and cheese is fully melted. Adjust heat as needed to avoid burning.
04 - Remove sandwiches from heat and let rest for 1 to 2 minutes. Slice diagonally and serve warm.
