- 4 medium onions sliced
- 3 tbsp butter
- 2 tbsp flour
- salt to taste
- 1 dash pepper
- 3 ⁄4 cup beef broth
- 1 ⁄4 cup sherry
- 1 1 ⁄2 cups croutons plain
- 2 tbsp butter melted
- 1 ⁄2-1 cup shredded Swiss cheese
- 3 tbsp grated Parmesan cheese grated
In a large skillet melt the butter over medium low heat. Add the onions and cook until they’re beginning to caramelize, stirring often, about 6-8 minutes.
Stir in the flour, salt, and pepper until the onions are evenly coated.
Whisk in the broth and sherry.
Continue to stir, cooking until thickened and bubbly.
Turn the onions out into a 1 quart casserole dish.
Toss the croutons with 2 tablespoons of melted butter and spoon them out evenly over top of the onion mixture.
Sprinkle the Swiss and Parmesan cheeses evenly overtop.
Put the casserole in the oven under the broiler and broil for about 1 minute, or until the cheese melts and just begins to brown.
Serve immediately.
