Ingredients

Scale
  • 4 red onions, sliced thin
  • 4 tablespoons salted butter
  • 46 slices hearty white bread
  • 3 cups shredded Gruyere cheese
  • 1 teaspoon sugar
  • 2 tablespoons salted butter
  • 2 tablespoons all-purpose flour
  • 1/3 cup apple juice
  • 1 can beef broth (14.5 oz can)
  • 1/2 teaspoon dried thyme leaves
  • 1/4 teaspoon pepper

Instructions

  1. Caramelize the onions: Melt butter in a Dutch oven over medium heat. Add sliced onions and sugar; stir to coat. Cook for about 35 minutes, stirring occasionally until golden brown.
  2. Prepare the dipping broth: In the same pot, melt more butter and whisk in flour until smooth. Gradually add thyme, apple juice, beef broth, and pepper; cook until slightly thickened (3-5 minutes).
  3. Assemble the sandwiches: Butter each side of the bread and grill in a pan over medium heat. Once one side is golden brown, flip it over, adding cheese and caramelized onions before topping with another slice of bread.
  4. Serve: Cut sandwiches into halves or quarters and serve alongside the delicious dipping broth.
