Ingredients
Scale
- 4 large yellow or sweet onions, thinly sliced
- 4 tbsp unsalted butter
- 6 cups low-sodium vegetable broth
- 2 tsp fresh thyme (or 1 tsp dried thyme)
- Salt and pepper to taste
- 1 French baguette, sliced into thick pieces
- 2 cups shredded Gruyère cheese
Instructions
- 1. Sauté the Onions: In a skillet over medium heat, melt the butter and add the sliced onions. Cook until soft and caramelized, about 20 minutes, stirring occasionally to prevent burning.
- 2. Prepare the Soup: In your slow cooker, combine the caramelized onions with vegetable broth and thyme. Season lightly with salt and pepper.
- 3. Slow Cook: Cover and set the slow cooker on low for 6 hours, allowing flavors to meld.
- 4. Prepare Baguette: About 30 minutes before serving, broil baguette slices until golden brown.
- 5. Serve with Cheese: Ladle hot soup into bowls, place toasted baguette slices on top, and sprinkle with Gruyère cheese. Place under the broiler until cheese is bubbly and golden.
