Ingredients

• Ingredients
  1. 2 tablespoons pure olive oil
  2. 1 pound chorizo, sliced 1/4 inch thick (see Note)
  3. 1 large Spanish onion, coarsely chopped
  4. 8 garlic cloves, minced
  5. 1/4 cup finely chopped flat-leaf parsley
  6. 2 quarts chicken stock or canned low-sodium broth
  7. 2 quarts water
  8. 1/2 cup dried red beans (1/4 pound), soaked overnight and drained
  9. 1/2 cup dried navy beans (1/4 pound), soaked overnight and drained
  10. 2 bay leaves
  11. 1/4 teaspoon dried thyme
  12. 1/4 teaspoon crushed red pepper
  13. 2 large baking potatoes, peeled and cut into 3/4-inch chunks
  14. 1 pound kale, tough stems and ribs removed, leaves coarsely chopped
  15. Salt and freshly ground pepper
  16. Crusty Portuguese bread, for serving

Directions

1. Heat the olive oil in a stockpot. Add the chorizo and onion and cook over high heat, stirring, until the onion is softened, about 3 minutes. Add the garlic and parsley and cook, stirring, for 2 minutes. Add the chicken stock, water, red and navy beans, bay leaves, thyme and crushed red pepper and bring to a boil. Cook over moderate heat until the beans are tender, about 1 1/4 hours.
2. Add the potatoes and kale to the stockpot, season with salt and pepper and cook over moderate heat, stirring occasionally, until the potatoes are tender, about 30 minutes. Remove the bay leaves. Serve the soup in deep bowls with plenty of crusty bread.

Make Ahead

The soup can be refrigerated for up to 3 days.
