How To Make this Rich Slow Cooker French Onion Soup

To make this rich Slow Cooker French Onion Soup, start by preparing 6 lbs of sliced onions. In a large skillet, melt 1/4 cup of butter over medium heat. Add the sliced onions, sautéing them until they become soft and translucent, eventually reaching a beautiful caramel color.
This process may take some time, so be patient and consider doing it in three batches to guarantee even cooking. Once the onions are caramelized, transfer them to your slow cooker.
Next, deglaze the skillet by adding a splash of the 14 cups of beef stock, scraping up any flavorful bits stuck to the bottom of the pan. Pour this mixture into the slow cooker along with the remaining beef stock, 1/2 teaspoon of Worcestershire sauce, 1 bay leaf, and 1/4 teaspoon of thyme.
Season with salt and pepper to taste. Cover the slow cooker and let the soup cook on high for 4 hours or on low for 6-8 hours, allowing the flavors to meld beautifully.
Once the cooking time is complete, remove the bay leaf and give the soup a final taste, adjusting the seasoning as needed. When you’re ready to serve, divide the soup into bowls.
For a delightful finish, add 2 tablespoons of sherry wine to the soup and stir. Place a slice of toasted crusty bread on top of the soup, sprinkle with 2 tablespoons of grated Parmesan cheese, and top with 1/4 cup of shredded Gruyère cheese.
To melt the cheese, place the bowls under the broiler for a few minutes until bubbly and golden. Enjoy the comforting warmth of your homemade French Onion Soup!
