Bread & Cheese
- French bread or sourdough, sliced (4 slices)
- Sharp Gruyere or Swiss cheese, shredded or sliced (1 to 1½ cups)
Produce & Flavorings
- Yellow or red onions, thinly sliced (2 medium)
- Apple (Granny Smith or Honeycrisp), thinly sliced with skin on or peeled (1 medium)
- Fresh thyme or other herbs (optional, 1 teaspoon)
Other Ingredients
- Butter (2 to 3 tablespoons, for cooking and spreading on bread)
- Olive oil (optional, for caramelizing onions)
- Caramelize the Onions: Thinly slice the onions and cook slowly over low heat in butter or olive oil, stirring often, until they turn golden brown and fragrant, about 20 to 30 minutes.
- Prepare the Apples: Core and thinly slice the apples, leaving the skin on for color and texture or peeling if preferred. Keep slices uniform for even sandwich layering.
- Assemble the Sandwich: Butter one side of each bread slice. On the non-buttered side, layer caramelized onions, apple slices, and shredded or sliced cheese generously. Sprinkle fresh thyme or herbs in between layers if using.
- Grill to Golden Perfection: Place the sandwich on a preheated skillet over medium-low heat, buttered side down. Press gently with a spatula and cook until the bread is golden and crisp and the cheese melts, about 3 to 5 minutes per side.
- Serve Hot and Savor: Remove the grilled sandwich from the pan, let it cool for a minute to set, then slice and enjoy immediately while melty and delicious.
Notes
- Onion Caramelizing Patience: Keep the heat low to ensure sweet, soft onions without burning.
- Thin Apple Slices: Thin slices prevent the sandwich from becoming overly bulky and maintain balanced bites.
- Low and Slow Grilling: Cooking slowly at medium-low heat crisps bread and fully melts the cheese.
- Choose Meltable Cheese: Gruyere or Swiss melt best for a creamy texture; avoid hard cheeses that do not melt well.
- Buttering Bread Evenly: Spread butter to the edges of the bread for a uniform golden crust without burnt spots.
