A comforting French Onion Grilled Cheese Sandwich featuring caramelized onions, melted Gruyère and Swiss cheeses, and a crispy golden crust made using butter and mayonnaise. This sandwich combines sweet, savory, and tangy flavors for a deliciously satisfying meal perfect for lunch or dinner.

Ingredients

Scale

For the Sandwich:

  • 2 tablespoons unsalted butter
  • 1 large onion, thinly sliced
  • 4 slices of your favorite bread (sourdough, whole wheat, or white)
  • 2 tablespoons mayonnaise
  • 2 tablespoons Dijon mustard
  • 2 cups shredded Gruyère cheese
  • 2 cups shredded Swiss cheese
  • Salt and pepper, to taste

Instructions

  1. Prepare the Caramelized Onions: In a large skillet, melt 1 tablespoon of butter over medium heat. Add the thinly sliced onions and sauté for 10-12 minutes, stirring occasionally until the onions become golden brown and caramelized. Season them with salt and pepper to taste, then remove from the skillet and set aside.
  2. Assemble the Sandwiches: Spread a thin layer of mayonnaise on one side of each slice of bread. On the opposite side of each slice, spread a layer of Dijon mustard. On the mustard side, evenly distribute a generous amount of shredded Gruyère and Swiss cheeses. Top the cheese with a few spoonfuls of the caramelized onions.
  3. Grill the Sandwiches: Using the same skillet, melt the remaining 1 tablespoon of butter over medium heat. Place the assembled sandwiches in the skillet, mayonnaise side down, and grill each side for 4-5 minutes or until the bread is golden brown and the cheese has melted completely.
  4. Serve: Remove the sandwiches from the skillet, slice them diagonally, and serve immediately while hot for the best taste and texture.

Notes

  • You can use any preferred type of bread such as sourdough or whole wheat to suit your taste.
  • Monitoring the onions closely during caramelization will prevent burning and ensure sweetness.
  • For extra crispiness, mayonnaise is spread on the bread before grilling.
  • To make it vegetarian, use bread without animal-derived ingredients and ensure cheese is suitable.
  • Leftover sandwiches can be refrigerated and reheated gently in a skillet or oven to maintain crispiness.
