  5. Add the caramelized onions to the mixture, along with 1 1/2 cups of Swiss cheese and the French bread cubes. Stir until everything is evenly distributed.
  6. Transfer the mixture to a greased casserole dish. Top with the remaining Swiss cheese.
  7. Bake in the preheated oven for 30-35 minutes, or until the cheese is melted and bubbly, and the top is golden brown.
