Ingredients

  • 5 tablespoons salted butter, divided

  • 4 medium onions, chopped

  • 2 tablespoons all-purpose flour

  • 1 pinch ground black pepper

  • ¾ cup beef broth

  • ¼ cup dry sherry

  • 1 ½ cups plain croutons

  • ½ cup shredded Swiss cheese

  • 3 tablespoons grated Parmesan cheese

Directions

  1. Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.

  2. Heat 3 tablespoons of butter in a pot over medium-high heat. Cook onions in the hot butter until tender, 5 to 7 minutes. Blend in flour and pepper. Add broth and sherry; cook and stir until thickened and bubbly. Pour into a 1-quart casserole dish.

  3. Melt remaining 2 tablespoons butter and toss with croutons. Spoon over onion mixture. Sprinkle with Swiss and Parmesan cheeses.

  4. Place under the preheated broiler just until cheeses melt, about 5 minutes. Serve immediately.
