Savor the rich, caramelized flavor of French Onion Grilled Cheese, where sweet, tender onions melt into gooey cheese between crispy bread. Follow our easy steps for a cozy meal that delights!

Ingredients

Scale
  • 2 large onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon sugar
  • Salt and pepper to taste
  • 4 slices of sourdough bread
  • 4 slices of Gruyère cheese
  • 2 tablespoons Dijon mustard

Instructions

  1. Step 1: In a large skillet, melt the butter and olive oil over medium heat. Add the sliced onions and stir to coat them in the fat.
  2. Step 2: Sprinkle the sugar over the onions and season with salt and pepper. Cook the onions, stirring occasionally, for about 20-25 minutes or until they are caramelized and golden brown.
  3. Step 3: While the onions are cooking, spread Dijon mustard on one side of each slice of sourdough bread.
  4. Step 4: Once the onions are caramelized, assemble the sandwiches by placing a slice of Gruyère cheese on the unbuttered side of two slices of bread, followed by a generous portion of caramelized onions, another slice of cheese, and then topping with the other two slices of bread (mustard side in).
  5. Step 5: Heat a skillet over medium heat and add a little butter. Grill each sandwich for about 3-4 minutes on each side until golden brown and the cheese is melted. Serve hot and enjoy!

Notes

  • For optimal storage, wrap any leftover French Onion Grilled Cheese sandwiches in parchment paper and place them in an airtight container in the refrigerator for up to 2 days.
  • When reheating, try using a skillet on low heat to gently warm the sandwich, which helps maintain the crispy crust while ensuring the cheese melts perfectly without burning.
  • Serve your grilled cheese with a side of homemade tomato soup or a simple green salad for a delightful meal that balances richness with freshness.
  • To enhance flavor, consider adding a pinch of thyme or rosemary to the caramelizing onions; it complements the Gruyère cheese beautifully and elevates the overall taste of the sandwich.
