Cooking Instructions
Follow our step-by-step guide on how to make Slow Cooker Onion Soup.
Step 1
Begin by assembling all your ingredients in one place for a seamless cooking experience.
Step 2
In a sturdy, large pot, melt the butter over medium-high heat.
Step 3
Introduce the sliced onions, stirring frequently until they turn translucent, which should take around 10 minutes.
Step 4
Sprinkle a touch of sugar over the onions and lower the heat to medium.
Step 5
Keep stirring as the onions soften and caramelize, a process that will take at least 30 minutes.
Step 6
Once they are beautifully golden, add the minced garlic and sauté for an additional minute until the aroma fills your kitchen.
Step 7
Pour in the cooking sherry, using a spatula to scrape up any flavorful browned bits from the bottom of the pot.
Step 8
Transfer the luscious caramelized onions to a slow cooker, then add the beef broth.
Step 9
Season generously with sea salt, and stir in the dried thyme and bay leaf for an aromatic touch.
Step 10
Cover the slow cooker and let it work its magic on Low for 8 to 10 hours or on High for 4 to 6 hours.
Step 11
About 10 minutes before you’re ready to serve, preheat your oven broiler and position an oven rack about 8 inches from the heat source.
Step 12
Lay the slices of French bread on a baking sheet and broil them until they are perfectly toasted, roughly 1 to 2 minutes per side.
Step 13
In a mixing bowl, combine the Gruyere, Emmental, Parmesan, and mozzarella cheeses, tossing them lightly to blend.
Step 14
Fill oven-safe soup crocks three-quarters full with the rich onion soup, then float a slice of your toasted bread on top of each bowl.
Step 15
Generously sprinkle about 2 tablespoons of the cheese mixture over each slice of bread.
Step 16
Place the filled bowls on a baking sheet and broil them until the cheese is gloriously browned and bubbling, which should take about 2 minutes.
Step 17
Enjoy the delightful aroma and the comforting warmth of this classic dish as you serve it up!.
