Ingredients
- 2.5 pounds onion sliced into half-moons, yellow
- 2 tablespoons olive oil
- 6 cups beef broth low-sodium
- 2 teaspoon Worcestershire sauce
- salt to taste, kosher salt
- black pepper to taste, kosher salt
- 1 baguette sliced, French
- 1 cup gruyere cheese shredded
- 2 thyme sprigs, fresh
Instructions
- Heat 2 tbsp of the oil in a soup pot over medium heat. Add the sliced onions and cook, stirring occasionally, for 35-40 minutes, or until golden and caramelized.
- Add the broth, Worcestershire sauce, salt, and pepper, and bring the soup to a boil. Reduce the heat and simmer for 30 minutes.
- Meanwhile, preheat the oven to 325ºF and line a sheet pan with parchment paper. Arrange the baguette slices on the prepared sheet pan and sprinkle with the cheese. Bake for 12-15 minutes, or until the cheese melts.
- Serve the soup with a cheesy baguette toast and garnish with fresh thyme.

Notes
- Storing leftovers: Place any leftovers in an airtight container in the refrigerator for up to 3-5 days without the baguette on top. Reheat in the microwave or on the stovetop, and then top it with the cheesy baguette as instructed.
- To freeze: Let the soup cool completely, then transfer it to a freezer-friendly container or bag, and freeze for up to 3 months. When you’re ready to eat it, thaw the soup in the fridge overnight, and then reheat it in the microwave or on the stovetop. Top with a cheesy baguette and serve!
