French Onion Grilled Cheese Sandwich


Description

A comforting and elevated twist on the classic grilled cheese, featuring caramelized onions and melty Gruyère for a rich, savory sandwich experience.


Ingredients

Scale
  • 2 large onions, thinly sliced
  • 2 tablespoons butter
  • Salt and pepper to taste
  • 4 slices of bread (sourdough or country loaf)
  • 4 slices of cheese (e.g., Gruyère, Swiss, or sharp cheddar)
  • 1 tablespoon olive oil

Instructions

  1. In a pan over medium heat, melt the butter and add the sliced onions. Cook until the onions are caramelized, about 15–20 minutes, stirring occasionally. Season with salt and pepper.
  2. Heat a separate pan or griddle and add olive oil.
  3. Assemble the sandwiches by placing cheese and caramelized onions between two slices of bread.
  4. Grill the sandwich on the pan until the bread is golden brown and the cheese is melted, flipping once.
  5. Remove from heat, slice, and serve warm.

Notes

For a tangy lift, add 1 teaspoon of balsamic vinegar to the onions while caramelizing. For a dairy-free option, substitute butter and cheese with vegan alternatives. Best served with a bowl of tomato soup.
