Description
Crockpot French Onion Soup is a rich, savory, and comforting dish featuring caramelized onions in a flavorful beef broth, topped with toasted bread and gooey melted cheese. Slow-cooked to perfection, it’s an easy way to enjoy a classic French favorite.
Ingredients
- 6 large yellow onions, thinly sliced
- 4 tablespoons butter
- 3 cloves garlic, minced
- 1/2 cup dry white wine or cooking sherry
- 8 cups low-sodium beef broth
- 1 tablespoon Worcestershire sauce
- 1 bay leaf
- 1 teaspoon fresh thyme or 1/2 teaspoon dried thyme
- Salt and pepper to taste
- 1 baguette or French bread, sliced and toasted
- 2 cups shredded Gruyère or Swiss cheese
Instructions
- In a skillet over medium heat, melt the butter and add the sliced onions. Cook slowly, stirring occasionally, until onions are soft and deeply caramelized, about 30–40 minutes.
- Add the minced garlic and sauté for 1 minute until fragrant.
- Pour in the wine or sherry to deglaze the pan, scraping up browned bits.
- Transfer the onion mixture to a crockpot. Add beef broth, Worcestershire sauce, bay leaf, thyme, salt, and pepper.
- Cover and cook on low for 6 to 8 hours or high for 3 to 4 hours.
- Toast the baguette slices until crisp.
- Ladle soup into oven-safe bowls, top each with a toast slice, and sprinkle generously with shredded cheese.
- Place bowls under the broiler until the cheese is bubbly and golden brown. Serve hot.
Notes
- Caramelizing onions slowly is crucial for developing rich flavor.
- Use oven-safe bowls for broiling the cheese topping.
- Substitute vegetable broth and vegan Worcestershire for a vegetarian version.
- Freeze soup without bread and cheese for up to 3 months.
