Instructions
- Step 1: Thinly slice 4 onions using a mandoline or sharp knife, then place them in a large Dutch oven with 2 tbsp olive oil. Cook over medium-low heat, stirring occasionally, for 20-25 minutes until they turn deep amber-brown and release a sweet, caramelized aroma. Tip: Avoid stirring too frequently in the first 10 minutes to allow the onions to develop color without burning.
- Step 2: Add 4 cups beef broth, 200g white beans (rinsed and drained), and 2 chiles (roasted, peeled, and seeded for milder heat or left whole for smokier flavor). Bring to a gentle boil, then reduce heat to low, cover, and simmer for 30 minutes until the beans are tender and the soup thickens slightly. Tip: Skim any foam that rises to the surface during boiling for a clearer broth.
- Step 3: Meanwhile, toast 4 slices French bread under a broiler or in a toaster until golden and crisp, about 3-4 minutes. Set aside.
- Step 4: Ladle the soup into 4 bowls, then top each with a toasted bread slice and 25g grated Gruyère cheese. Broil the bowls under the oven’s broiler for 3-4 minutes until the cheese is golden-brown, bubbly, and slightly caramelized at the edges. Tip: For a richer flavor, stir 1 tbsp heavy cream into the soup before adding the bread and cheese.
