Ingredients

  • 1/4 cup butter
  • 2 large onions thinly sliced
  • 1/4 cup Marsala wine
  • 3 tablespoons minced fresh rosemary
  • 1 tablespoon minced fresh thyme
  • 1 teaspoon dried sage
  • 2-1/2 cups beef broth
  • 2 large eggs
  • 10 cups stale bread cubes
  • Salt and pepper to taste
  • 1/2 cup shredded swiss cheese

Instructions

  • In a medium saucepan over medium heat, melt butter. Add onions to pan and slowly cook over medium heat, stirring occasionally until onions are a deep golden-brown and caramelized, about 25 minutes. Stir Marsala wine and seasonings into onions and let cook 2 minutes. Add beef broth and bring to a very light simmer. Remove from heat.
