Ingredients

  • 3 tablespoons unsalted butter
  • 1 Vidalia onion, sliced very thin
  • 4 slices sourdough bread
  • 6 ounces Gruyère cheese, shredded

Instructions

  • In a large skillet, melt the butter over low heat. Add the onion and cook, stirring occasionally, for 25 minutes, until the onion is golden and caramelized. Remove from skillet.
  • Turn the heat up to medium. Spread butter on the outside pieces of sandwich bread. Lay flat with insides up and spread cheese and onion out evenly between the two sandwiches. Place the tops on the sandwiches and cook them in the skillet, flipping once until the cheese is melted and bread is golden brown.

Notes

This recipe makes two large sandwiches. Could easily serve 4 people, if cut in half and served with tomato soup.
Sprinkle a little dried or fresh thyme over the onion while it's cooking.
