French Melt (Grilled Cheese With Caramelized Onion and Comté) Recipe

Photographs: J. Kenji Lopez-Alt

French Melts start with a big ol' pile of sweet, caramelized onions (see here for an easy technique to speed up the process) melted with a fat slab of Comté cheese. It's like French onion soup in an easy-to-pick-up, extra-buttery package. Set the table cloth and pull out the fine china, dear, tonight I'm wearing pants to the table!

Rate & Comment


  • 4 tablespoons butter, divided

  • 2 medium onions, thinly sliced

  • Kosher salt and freshly ground black pepper

  • 4 slices crusty country-style bread

  • 4 ounces Comté or Gruyère cheese, sliced


  1. Heat 1 tablespoon in a large non-stick of cast iron skillet over medium-low heat until melted. Add onions, season with salt and pepper and cook, stirring frequently, until deeply caramelized and rich brown, about 45 minutes (If onions threaten to burn, add 1 tablespoon of water). Transfer onions to a bowl and wipe out skillet.

  2. Return skillet to medium heat and melt 1 tablespoon butter. Add bread slices and cook, swirling bread around pan, until pale golden brown, about 2 minutes. Transfer to a cutting board, cooked-side-up. Divide cheese evenly between each slice. Spread onions evenly between two slices. Close sandwiches with onions and cheese inside.

  3. Melt 1 more tablespoon butter in skillet and add both sandwiches. Cook, swirling pan frequently, until deep golden brown on first side, about 3 minutes. Add remaining tablespoon butter, flip sandwiches, and continue cooking until deep golden brown and cheese is melted, about 3 minutes longer. Serve immediately.
