3 medium sweet onions, sliced
3 tablespoons butter
4 cups beef broth
1 teaspoon Worcestershire sauce
Approximately 4 ounces French baguette bread, sliced about ½-inch in thickness (approximately 10-12 small slices)
1 cup (4 ounces) shredded mozzarella cheese
¼ cup grated Parmesan cheese

  1. Melt butter in a large saucepan over low heat.
    Add onions and cover. Cook for about 30 minutes, stirring occasionally.
    Add the beef broth and the Worcestershire sauce. Heat the broth mixture until it boils.
    Reduce heat to low. Allow to simmer, uncovered, for about 30 minutes. The broth will reduce.
    Pour onion and broth mixture into a medium greased casserole dish (you can use a 1 ½-quart baking dish, an 11×7-inch baking dish, a 9-inch square baking dish, or something similar in size).
    Lightly toast the slices of bread.
    Place toasted bread in a single layer on top of onion/broth mixture.
    Cover bread with a thick layer of the shredded mozzarella and top with grated Parmesan.
    Bake, uncovered, in a 350 degree oven for 20-30 minutes, or until cheese is melted and brown on top.

In just 10 minutes you can prep this easy French Onion Soup Casserole for an easy side dish or a hearty vegetarian dinner!
