This Apple Grilled Cheese is an irresistible combination of sautéed apples, sweet caramelized onions, brie and white cheddar cheeses, Dijon mustard and walnuts. It's the best toasted sandwich you've ever made at home!
Heat 1 tablespoon butter in large skillet over medium-low heat. Add onion and cook 30 minutes or until dark golden brown, stirring occasionally.
Add apple, thyme and water; cook 10 to 15 minutes or until apple is very soft and water has evaporated, stirring frequently.
To build sandwiches, place bread slices on work surface. Spread mustard on 4 slices of bread, and drizzle honey on remaining 4 slices of bread. Divide apple mixture over honey-drizzled slices of bread, and make sure mixture is evenly spread. Divide cheddar cheese over apple mixture; place brie slices over cheddar. Sprinkle brie with walnuts. Place mustard-spread slices of bread on top, mustard side down.
Heat remaining 2 tablespoons of butter on griddle or in large skillet over medium heat. Working in batches if necessary, add sandwiches to griddle and cook 8 to 10 minutes or until bread is very toasted and cheese is melted, turning frequently. Cut sandwiches in half to serve.
Notes
Steps 1 and 2 take a little bit of time, because properly caramelizing onions can’t be rushed. But it’s not active time where you’ll have to stand at the stove.
