French 洋蔥 湯 is the ultimate comfort food. Caramelizing the onions takes patience, but the resulting deep sweet broth is worth every minute.

Ingredients (Serves 2)

• Onions: 2 large (thinly sliced)
• Butter: 20g
• 牛肉 or vegetable broth: 400ml
• Bay leaf: 1
• Salt and black pepper: to taste
• Baguette slices: 2 (toasted)
• Gruyère or shredded mozzarella 起司: 1/2 cup

Instructions

1. Caramelize: Melt butter in a heavy pot. Add onions and cook on low heat, stirring occasionally, for 30–40 minutes until deep brown and sweet.
2. Simmer: Add broth and bay leaf. Simmer for 15 minutes, then 季節 with salt and pepper.
3. Assemble: Pour 湯 into oven-safe bowls, float toasted baguette slices on top, and cover generously with 起司.
4. Broil: Broil in a hot oven or toaster until the 起司 is melted and bubbly brown.
