Directions
- Melt butter in a large pot over medium heat.
- Add the sliced onions and a pinch of salt; cook until they soften and release moisture, about 4–5 minutes, stirring occasionally.
- Stir in the broth, soy sauce, Worcestershire, pepper, and dried thyme; bring the mixture to a boil, then reduce the heat and simmer for 10–15 minutes.
- While the soup simmers, prepare the bread and cheese: slice the bread and grate the mozzarella and Parmesan.
- Heat the broiler and place the oven rack about 6 inches from the heat source.
- Portion the soup into oven-safe bowls set on a baking sheet; top each with bread slices and a generous layer of cheese.
- Broil until the cheese is melted and browned, watching closely as it can burn quickly, roughly 1 minute; remove the bowls with oven mitts and serve warm.
Two tips
- Prep ahead: slice onions and grate cheese up to a day in advance and refrigerate.
- Serving idea: dot a little extra parmesan atop the soup just before serving, or offer a side of extra bread for dunking.
