Components

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

01 4 slices sourdough or country bread
02 2 tablespoons unsalted butter, softened
03 1 medium crisp apple (Granny Smith or Honeycrisp), thinly sliced
04 4 ounces sharp cheddar cheese, sliced or shredded
05 Freshly ground black pepper, to taste

Method

Phase 01

Caramelize Onions: Melt butter and olive oil in a skillet over medium-low heat. Add sliced onions and salt. Cook, stirring frequently, for 15–18 minutes until onions are golden and tender. Add sugar halfway through if sweetness is desired. Remove from heat and set aside.

Phase 02

Assemble Sandwiches: Spread softened butter on one side of each bread slice. On the unbuttered side of two slices, layer half the cheddar cheese, caramelized onions, apple slices, a pinch of black pepper, and remaining cheddar. Top with the other bread slices, buttered side facing out.

Phase 03

Cook Sandwiches: Heat a nonstick skillet or griddle over medium heat. Place sandwiches in the skillet and cook for 3–4 minutes on each side, pressing gently, until bread is golden and cheese is melted. Lower heat if bread browns too quickly.

Phase 04

Rest and Serve: Remove sandwiches from heat. Allow to cool for 1–2 minutes before slicing and serving warm.
