Onion soup baked under a cheese crust
6 servings
100 minutes
Onion soup baked under a cheese crust is a true embodiment of French culinary elegance. Its roots go back to medieval France when simple ingredients were transformed into exquisite dishes. Tender, caramelized onions infused with thyme aroma combine with rich beef broth and white wine to create a deep, warming flavor. Crispy garlic-rubbed croutons soak up this broth, topped with a golden crust of melted Gruyère cheese that gives the soup an unmatched creamy texture. This soup is perfect for cozy evenings when you want to feel the warmth of a French home.
