A delicious and comforting Caramelized Onion and Apple Grilled Cheese Sandwich featuring sweet, golden onions, crisp honeycrisp apples, sharp cheddar, and creamy brie with fragrant sage butter on toasted sourdough bread.

Ingredients

Scale

Bread and Butter

  • 4 slices sourdough bread
  • 6 tbsp unsalted butter, divided (room temperature)
  • 1 tbsp fresh sage, chopped
  • 1 tbsp olive oil
  • 2 tsp kosher salt, divided

Filling

  • 1 honeycrisp apple, thinly sliced
  • 2 large yellow onions, sliced 1/2 inch thick
  • 8 oz cheddar cheese, grated
  • 2 oz brie cheese, sliced into 1/2 inch slivers

Instructions

  1. Caramelize Onions: Heat 2 tbsp unsalted butter in a skillet over medium heat. Add the sliced onions and stir every few minutes. After 10 minutes, sprinkle 1 tsp kosher salt over the onions. Continue to cook, stirring occasionally, for an additional 30-40 minutes until the onions turn golden and caramelized. Add 1 tbsp water if the pan becomes too dry to prevent burning.
  2. Prepare Sage Butter: In a small bowl, mix the chopped fresh sage with the remaining 4 tbsp unsalted butter and 1 tsp kosher salt until well combined. Set aside.
  3. Assemble Sandwiches: Place one slice of sourdough bread (without butter) on a clean surface. Layer with brie cheese, then a generous amount of grated cheddar cheese, followed by thinly sliced apples arranged in a slightly overlapping single layer. Spread about 1/4 cup of the caramelized onions over the apples, then add another layer of cheddar cheese. Top with the second slice of bread. Spread 1 tbsp of the prepared sage butter evenly on the top slice of bread.
  4. Grill Sandwiches: Heat a skillet over medium heat and add 1 tbsp olive oil. Place the assembled sandwiches in the skillet buttered-side down. Spread the remaining sage butter evenly on the top exposed bread slices. Cook each side for about 6 minutes, or until the bread is golden brown and the cheese has melted thoroughly. Remove from heat and serve warm.

Notes

  • Use honeycrisp apples for a balance of sweetness and tartness that complements the cheese and onions.
  • If you prefer a milder onion flavor, cook the onions for less time; longer caramelization brings out more sweetness.
  • Feel free to substitute sourdough with your favorite sturdy sandwich bread to hold the fillings well.
  • For a vegetarian version, ensure the cheese used is free from animal rennet.
  • Serve immediately after cooking to enjoy the best texture and melty cheese.
