Slow-Braised Castelluccio Lentil and Walnut Ragù over Stone-Ground Polenta

Introduction

Benvenuti alla mia tavola. Today, I reached into the pantry for dried Castelluccio lentils, rich Tuscan walnuts, and dark lacinato kale harvested crisp from the garden. We are letting them simmer gently with Chianti and crushed tomatoes until thick and velvety, then resting the ragù over creamy, slow-stirred stone-ground polenta. It is pure cucina povera elegance: humble, warming, and made whole with a generous pour of green, peppery new-harvest olive oil.

Ingredients

• 1 cup dried brown Castelluccio lentils, rinsed
• 1 cup raw walnuts, finely chopped to mimic rustic mince
• 1 medium yellow onion, finely diced
• 1 large carrot, finely diced
• 1 stalk celery, finely diced
• 3 cloves garlic, minced
• 2 tablespoons double-concentrated tomato paste
• 1 cup dry Tuscan red wine (such as Chianti)
• 1 can (14 oz / 400 g) whole San Marzano tomatoes, crushed by hand
• 3 cups vegetable broth or simmering water
• 2 fresh bay leaves
• 2 sprigs fresh rosemary, tied with kitchen twine
• 1 bunch cavolo nero (Tuscan kale), stems removed and leaves shredded
• 1 cup coarse stone-ground yellow polenta (bramata)
• 4 cups water or vegetable broth for polenta
• 1/4 cup top-grade extra virgin olive oil, plus extra for drizzling
• 1 teaspoon sea salt and cracked black pepper to taste

Instructions

1. Heat 3 tablespoons of extra virgin olive oil in a heavy-bottomed terracotta pot or Dutch oven over medium-low heat.
2. Add the diced onion, carrot, and celery with a pinch of sea salt, gently sweating the soffritto for about 12 minutes until translucent and sweet.
3. Stir in the garlic and chopped walnuts, toasting them gently for 3 minutes until fragrant.
4. Clear a small space in the center of the pot, add the tomato paste, and let it caramelize for 2 minutes before deglazing with the red wine, scraping up the golden bits from the bottom.
5. Once the wine reduces by half, pour in the rinsed lentils, hand-crushed tomatoes, vegetable broth, bay leaves, and rosemary bundle.
6. Bring to a gentle boil, then lower the heat to the lowest setting, cover partially, and let it slow-cook for 50 minutes, stirring occasionally and adding a splash of warm water if it thickens too quickly.
7. Fold in the shredded cavolo nero during the last 15 minutes of braising until tender, silky, and deeply incorporated into the ragù; season carefully with sea salt and cracked pepper, discarding the rosemary stems and bay leaves.
8. Meanwhile, in a separate heavy saucepan, bring 4 cups of salted water or broth to a simmer and slowly rain in the stone-ground polenta while whisking continuously to prevent lumps.
9. Reduce the heat to low and cook the polenta for 40 minutes, stirring frequently with a wooden spoon until thick, smooth, and pull-away tender.
10. Spoon warm polenta into wide earthenware bowls, ladle the rich, steaming walnut and lentil ragù generously over the top, and crown with a vibrant swirl of cold-pressed Tuscan olive oil.

Serve this steaming pot directly in the center of a rustic table with crusty sourdough to swipe every last drop. In Tuscany, food is not hurried; it is coaxed with patience, respect, and good conversation. Buon appetito!
