6 ounces chestnuts
3 slices bacon, diced
4 tablespoons (½ stick) unsalted butter
1 pound Brussels sprouts, halved
6 small shallots, quartered
Freshly ground black pepper
Preheat the oven to 400ºF. Using a chestnut knife, cut an X in the cheek of each chestnut. Arrange the chestnuts in a single layer on a baking tray and bake for 25 to 35 minutes, or until tender. Let rest for about 5 minutes, or until just cool enough to handle. Peel and dice.
Meanwhile, heat a large, heavy sauté pan over medium-low heat until hot but not smoking. Add the bacon and fry, tossing frequently, for 7 to 8 minutes, or until rendered. Using a slotted spoon, transfer the bacon to a small bowl. Add the butter to the pan and heat until it melts, bubbles, and the foam subsides. Add the Brussels sprouts, shallots, and chestnuts and toss to coat with the butter. Season generously with salt and pepper. Transfer the pan to the oven and roast for 20 to 22 minutes, or until the Brussels sprouts are tender and golden brown. Toss in the bacon, transfer to a bowl, and serve immediately.
Serves 6. Enjoy in the fall, when both Brussels sprouts and chestnuts are in season. Chestnuts are easiest to peel when they're hot. For the best results, be sure not to overcrowd the pan.
