Assemble: Ladle soup into oven-safe bowls. Top each with a toasted baguette slice and a generous layer of Gruyère cheese. Broil until the cheese bubbles and turns golden.
Finish with Crispy Shallots: Sprinkle the fried shallots on top just before serving for crunch, flavor, and visual appeal.
For extra depth, add a splash of brandy or sherry while deglazing the onions.
Swap Gruyère for a mix of Swiss and Parmesan for a slightly different flavor profile.
Serve with a side of crusty bread to soak up every last bit of the savory broth.
By adding crispy shallots, this French onion soup becomes more than a classic—it becomes a culinary experience. Each spoonful delivers a perfect harmony of sweet caramelized onions, savory broth, gooey cheese, and that irresistible crunch from the shallots. It’s comfort food elevated, perfect for a cozy night in or an elegant dinner party.
