Golden grilled sandwich layered with caramelized onions, crisp apples, and melted cheddar on buttery sourdough bread.
# What's Needed:
→ 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
08 - 1 medium crisp apple (e.g., Granny Smith or Honeycrisp), thinly sliced
09 - 4 ounces sharp cheddar cheese, sliced or shredded
10 - Freshly ground black pepper, to taste
# How To Make It:
01 - Melt butter with olive oil in a skillet over medium-low heat. Add sliced onion and salt, cooking and stirring frequently for 15 to 18 minutes until onions are soft and deeply golden. Optionally, incorporate sugar halfway through for added sweetness. Set aside.
02 - Spread softened butter on one side of each bread slice. On the unbuttered side, layer half the cheddar cheese, caramelized onions, apple slices, a sprinkle of black pepper, and the remaining cheddar. Top with the second slice of bread, buttered side facing out.
03 - Heat a nonstick skillet or griddle over medium heat. Cook sandwiches for 3 to 4 minutes per side, gently pressing, until bread is golden brown and cheese is melted. Reduce heat if bread browns too quickly.
04 - Remove sandwiches from heat and let rest for 1 to 2 minutes. Slice and serve warm.
