INGREDIENTS:
6 tablespoons Butter
4 large yellow Onions, sliced and separated into rings
1 tablespoon White Sugar
2 cloves Garlic, minced
½ cup Cooking Sherry
7 cups Beef Broth
1 teaspoon Sea Salt (or to taste)
¼ teaspoon Dried Thyme
1 Bay Leaf
8 slices French Bread
½ cup Gruyere cheese, shredded
⅓ cup Emmental cheese, shredded
¼ cup freshly Parmesan cheese, shredded
2 tablespoons Mozzarella Cheese, shredded
DIRECTIONS:
Heat butter in a large, heavy pot over medium-high heat; cook and stir onions until they become translucent, about 10 minutes.
Sprinkle onions with sugar; reduce heat to medium.
Cook, stirring constantly, until onions are soft and browned, at least 30 minutes.
Stir in garlic and cook until fragrant, about 1 minute.
Stir sherry into onion mixture and scrape bottom of pot to dissolve small bits of browned food from the pot.
Transfer onions into a slow cooker and pour in beef broth.
Season to taste with sea salt.
Stir in thyme and bay leaf.
Cover cooker, set on High, and cook 4 to 6 hours. If desired, set on Low and cook 8 to 10 hours.
About 10 minutes before serving, set oven rack about 8 inches from the heat source and preheat the oven's broiler.
Arrange bread slices on a baking sheet.
Broil bread slices until toasted, 1 to 2 minutes per side.
Combine Gruyere, Emmental, Parmesan, and mozzarella cheeses in a bowl, tossing lightly.
Fill oven-safe soup crocks 3/4 full of onion soup and float a bread slice in each bowl.
Top with about 2 tablespoons of cheese mixture per serving.
Place filled bowls onto a baking sheet and broil until cheese topping is lightly browned and bubbling, about 2 minutes.
