Pureed White Bean and Winter Squash Soup

Step 1

Drain the beans. Heat 1 tablespoon of the olive oil in a large, heavy soup pot over medium heat and add the onion. Cook gently until tender, about 5 minutes, and add 2 of the garlic cloves and 1/2 teaspoon salt. Stir together for about 30 seconds, then add the drained beans and the water. Bring to a boil and skim off foam. Add the bouquet garni, reduce the heat, cover and simmer 1 hour.

Step 2

Meanwhile, heat the remaining olive oil in a wide, heavy skillet over medium heat and add the leeks and 1/2 teaspoon salt. Cook gently, stirring, until tender, about 3 minutes, and add the remaining garlic and the squash. Cook, stirring, until the garlic is fragrant and the squash is coated with oil and just beginning to soften, about 2 minutes. Remove from the heat and stir into the beans. Add salt to taste and continue to simmer for another 30 minutes to an hour, until the beans and vegetables are thoroughly tender and falling apart. Taste and adjust salt. Remove the bouquet garni.

Step 3

Using an immersion blender or a food mill fitted with the fine or medium blade, puree the soup. Heat through, taste and adjust salt, and add pepper to taste. Serve, garnishing each bowl with slivered sage leaves, (optional) garlic croutons and an optional drizzle of olive oil.
