Number Of Ingredients 9

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

Steps:

Set an oven rack about 6 inches from the heat source and preheat the oven's broiler.
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.
Melt remaining 2 tablespoons butter and toss with croutons. Spoon over onion mixture. Sprinkle with Swiss and Parmesan cheeses.
Place under the preheated broiler just until cheeses melt, about 5 minutes. Serve immediately.
