4 large scallions, sliced
12 ounces Swiss chard (about 1 large bunch), preferably green, stems separated and chopped, leaves torn into 2-inch pieces
2 celery stalks, chopped
3 garlic cloves, finely chopped
3 fresh thyme sprigs
1/3 cup extra-virgin olive oil, plus more for serving
1/2 pound green beans, trimmed and cut into 1-inch pieces
2 cups frozen (or fresh) lima beans or edamame, thawed if frozen
1/2 teaspoon granulated sugar
Kosher salt (such as Diamond Crystal) and freshly ground black pepper
1/3 cup dried or fresh bread crumbs
Crusty bread, for serving
This light, plant-based main was inspired by a traditional cassoulet, a French slow-cooked casserole made with beans, pork and duck and simmered in duck fat. In this fast, vegetarian take, olive oil replaces the duck fat and chard stalks are cooked gently with scallion, garlic and thyme to create the flavor foundation. Summer vegetables are simmered in the infused olive oil until just tender, then served with toasted bread crumbs and fresh cracked pepper. The broth in this dish is the real star, so you will want lots of bread to soak it all up.
In a large saucepan, bring scallions, chard stems, celery, garlic, thyme and oil to a simmer over medium heat until oil is gently bubbling and chard stems are tender, 12 to 15 minutes. You want to slowly cook the vegetables and infuse the oil; you may need to adjust the heat to avoid browning the vegetables.
Add green beans, lima beans, chard leaves, sugar, 2 teaspoons salt, 1/2 teaspoon pepper and 2 cups water to the cooked vegetables. Bring to a simmer over medium heat. Cook, stirring occasionally, until green beans are just tender, about 8 minutes.
Meanwhile, heat a medium skillet over medium-high and toast bread crumbs, tossing frequently, until golden brown and fragrant, about 4 minutes. Transfer to a heatproof bowl.
Divide vegetable mixture among bowls and top with the toasted bread crumbs, a drizzle of olive oil and a grind of black pepper. Serve with crusty bread, for soaking up the broth.
