Escarole and White Bean Soup

Escarole and White Bean Soup

1 head Red Dog Farm Escarole (1 pound), tough ribs discarded and leaves thinly sliced (8 cups)
2 tablespoons olive oil
1 medium Onion, chopped
1 large Garlic clove, chopped
1 large Celery rib, cut diagonally into 1/8-inch-thick slices
2 Red Dog Farm Carrots, cut diagonally into 1/8-inch-thick slices
2 (13 1/2- to 14 1/2-ounce) cans chicken broth or vegetable broth
3 cups water
1 (16- to 19-ounce) can white beans such as cannellini, rinsed and drained
Accompaniment: grated Parmesan

Cook escarole in a 6- to 8-quart pot of boiling salted water until tender, about 5 minutes, then transfer with slotted spoon to a large bowl of ice and cold water to stop cooking. Drain escarole in a colander, pressing gently to remove excess water. Heat oil in a 5- to 6-quart heavy pot over moderately high heat until hot but not smoking, then sauté onion, garlic, celery, and carrots, stirring occasionally, until golden, about 8 minutes. Add chicken broth and water and bring to a boil, then add escarole and beans and simmer, uncovered, until carrots and celery are tender, about 10 minutes. Season with salt and pepper.
