Ingredients:

Grilled cheese with onion in a black pan

Directions:

  1. Heat 1 tablespoon butter and the olive oil in a large cast iron skillet over medium heat. When foam subsides, add onion; sauté until onion is translucent, about 5 minutes.
  2. Reduce heat to medium-low; continue cooking until onion is golden brown, stirring occasionally, about 20 minutes longer.
  3. Increase heat to high. Add broth to the skillet; cook until liquid has evaporated, about 3 minutes. Remove from heat. Stir in thyme; season with salt and pepper.
  4. Spread one side of each bread slice with 1-1/2 tablespoons butter, dividing evenly. Place 2 bread slices, in a large cast iron skillet, buttered side down.
  5. Top each with 2 cheese slices. Top with caramelized onions, dividing evenly.
  6. Top each with 1 cheese slice. Cover with remaining bread, buttered side up.
  7. Turn on heat to medium-low. Cook each sandwich until golden brown, 2 to 3 minutes per side.
  8. Place 1 cheese slice on top of each sandwich. Place sandwiches under broiler just until cheese melts.
