French Onion Mushroom Soup

French onion soup is already incredible, but adding earthy mushrooms takes it to another level. The sweetness of caramelized onions meets the umami depth of mushrooms, all topped with crusty bread and bubbling gruyère. It's bistro magic.

This mashup gives you the best of both worlds - the iconic French onion soup presentation with the added richness that only mushrooms can provide. It's comfort food worthy of a Parisian café.
