Spicy Beans with Wilted Greens

Directions

1. 1.

   Heat 1/4 cup oil in a large Dutch oven over medium heat. Cook anchovies, if using, chiles, and garlic, stirring occasionally, until garlic is soft and anchovies are dissolved, about 4 minutes. Add onion, celery, and rosemary; season with salt and pepper. Increase heat to medium-high and cook, stirring occasionally, until onion is very soft and golden brown, 8–10 minutes.

2. 2.

   Add Parmesan rind, if using, beans, and 10 cups water. Bring to a boil, reduce heat, and simmer, stirring occasionally and adding more water as needed, until beans are beginning to fall apart, 3–4 hours.

3. 3.

   Lightly crush some beans to give stew a creamy consistency. Mix in kale, spinach, and half of arugula; season with salt and pepper. Cook until greens are wilted, 5–8 minutes.

4. 4.

   Toss remaining arugula with lemon juice and 1 tablespoon oil; season with salt and pepper. Divide stew among bowls; top with arugula, shaved Parmesan, and a drizzle of oil.

5. 5.

   DO AHEAD: Stew can be made 3 days ahead. Let cool; cover and chill.
