Meaning reboiled in Italian, this hearty vegetarian soup lives up to its name. It's just as delicious on the day it's made as it is reheated. This recipe appears in our cookbook "Martha Stewart's Slow Cooker" (Clarkson Potter).


  • ¼ cup plus 2 tablespoons extra-virgin olive oil, plus more for serving

  • 1 onion, finely chopped

  • 3 cloves garlic, minced

  • ½ teaspoon red-pepper flakes

  • 1 bunch lacinato kale, stems removed, leaves cut into ½-inch ribbons (4 cups)

  • 2 medium zucchini, quartered lengthwise and cut into ½-inch slices

  • 1 large tomato, finely chopped

  • 1 cup fresh or frozen shelled cranberry beans

  • 1 ½ cups boiling water

  • Kosher salt and freshly ground black pepper

  • 2 slices country bread

  • Finely grated Parmigiano-Reggiano, for serving


  1. Preheat a 4-quart slow cooker. Heat 2 tablespoons oil in a large skillet over high. Add onion, garlic, and red-pepper flakes and cook until softened, about5 minutes. Add kale and cookuntil just wilted, 5 minutes. Transferto slow cooker.

  2. Add 1 tablespoon oil to skillet, then add zucchini and cook over high until lightly browned, 3 to 4 minutes. Transfer zucchini to slow cooker along with tomato, beans, and boiling water; season with salt and pepper. Cover and cook on high until beans are tender, 3 hours (or on low 6 hours).
