Patience is the key to this soul-satisfying soup chock-full of winter greens. Its depth of flavor comes from cooking the soffritto—a mixture of pancetta, onion, celery, carrots, and the ribs from the chard—for a good 45 minutes and from browning the tomato paste. The result is so savory that there’s no need for broth; water, canned tomatoes, and a parmesan rind work beautifully. And because this soup must cook slowly, don’t worry about prepping all your vegetables before you begin—you can simply chop as you go.

4

-
2
medium carrots, chopped
-
1/3
cup
extra-virgin olive oil
-
1
bunch Swiss chard
-
6
garlic cloves, finely chopped
-
2
tablespoons
tomato paste
-
1
(28-oz) can whole tomatoes in juice
-
1
qt
hot water
-
5
cups
coarsely chopped cored Savoy cabbage (6 oz)
-
5
cups
coarsely chopped escarole (1/2 lb)
-
1
piece Parmigiano-Reggiano rind (about 3 by 1 1/2 inches)
-
1
(19-oz) can cannellini beans, rinsed and drained
-
Cook pancetta, onions, celery, and carrots in oil in a wide 7- to 9-qt heavy pot over medium heat, stirring occasionally, while preparing chard.
-
Cut out stems from chard and chop stems, reserving leaves. Stir chard stems into pancetta mixture with garlic, 1 tsp salt, and 3/4 tsp pepper and continue cooking, stirring occasionally, until vegetables are very tender and begin to stick to bottom of pot, about 45 minutes total. (Set aside chard leaves.)
-
Push vegetables to one side of pot. Add tomato paste to cleared area and cook, stirring constantly, until it starts to caramelize, about 2 minutes. Stir paste into vegetables and cook, stirring, 2 minutes. (Paste may stick to pot, but don’t let it burn.)
-
Stir in tomatoes with their juice, breaking them up with a spoon, then add hot water (3 qt), scraping up any brown bits from bottom of pot.
-
Bring to a simmer. Stir in cabbage, escarole, and parmesan rind. Simmer, covered, until greens are tender, about 40 minutes.
-
Coarsely chop chard leaves and stir into soup along with beans. Simmer, partially covered, 10 minutes. Discard rind. Season soup with salt and pepper. If using ditalini, stir in just before serving.
