This is truly one of my favorite casseroles of all time. It’s tasty and very easy to make!
Check out what my pals over at Recipe Lion had to say about this recipe:
Legend has it that the first French Onion Soup was actually created by King Louis the XV of France when all that could be found in the pantry of his hunting party’s lodge was butter, onions and champagne. While the story cannot be confirmed or denied as myth of fact, it is an interesting bit of lore.
Well, how about that? A casserole created by a King!
Ingredients
3 medium sweet onions, sliced
3 tablespoons Kerrygold butter
4 cups beef broth
1 teaspoon Heinz Worcestershire sauce
Approximately 6-8 slices French bread, about 1/2-inch in thickness
1 cup Kraft shredded mozzarella cheese
1/2 cup grated Parmesan cheese
Instructions
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. All to simmer, uncovered, for about 30 minutes. The broth will reduce.
Pour onion and broth mixture into a greased casserole dish.
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 to 30 minutes, or until cheese is melted and brown on top.

Quick Tip: I like to eat this casserole with lots of Crusty french bread.
