Swiss Chard and Sweet Potato Gratin
Serves 12

1/4 cup (1/2 stick or 2 ounces) butter
1 small onion, finely chopped
3 pounds Swiss chard, leaves and stems separated and both cut into 1-inch pieces
Pinch of freshly grated nutmeg
2 cups heavy cream or whole milk
2 garlic cloves, minced
2 tablespoons flour
2 pounds medium red-skinned sweet potatoes (yams), peeled and cut into 1/8-inch thick rounds
1 tablespoon minced fresh Italian parsley
1 tablespoon minced fresh thyme
Fine sea salt
Freshly ground black pepper
1 1/4 cups (about 5 ounces) coarsely grated Gruyére cheese

Prep greens: Cook onion in 2 tablespoons butter in a wide 8-quart heavy pot over moderately low heat, stirring, until softened. Add chard stems, pinch of nutmeg, and salt and pepper to taste and cook, stirring, until vegetables are tender but not browned, about 8 minutes. Increase heat to moderately high and add chard leaves by large handfuls, stirring, until all greens are wilted. Season with salt and pepper then transfer greens to a colander to drain well and press out liquid with back of a large spoon.

Make sauce: Combine cream or milk and garlic in small saucepan; bring to simmer; keep warm. Melt two tablespoons butter in a medium heavy saucepan over moderate heat and stir in flour. Cook roux, whisking, one minute, then slowly whisk in warm cream/milk and boil, whisking, one minute. Season sauce with salt and pepper.

Assemble gratin: Preheat oven to 400°F. Butter deep 9×13 baking dish. Spread half of sweet potatoes in the prepared baking dish. Sprinkle with salt, pepper, a quarter of the herbs and a 1/4 cup of the cheese. Distribute half of the greens mixture over the cheese, then sprinkle salt, pepper, a quarter of the herbs and 1/4 cup of the cheese over it. Pour half of bechamel sauce over the first two layers then continue with the remaining sweet potatoes, more salt, pepper, herbs and cheese and then the remaining greens, salt, pepper and herbs. Pour the remaining sauce over the top of the gratin, pressing the vegetables slightly to ensure that they are as submerged as possible. Sprinkle with the last 1/4 cup of cheese.

Bake gratin for about 1 hour until golden and bubbly, and most of the liquid is absorbed. Let stand 10 minutes before serving.

Balsamic Braised Brussels with Pancetta
Serves 6 to 8 as a side

1 1/2 cups fresh bread crumbs
2 teaspoons thyme leaves
2 tablespoons extra virgin olive oil, plus more for drizzling
4 tablespoons unsalted butter
2 pounds medium-sized brussels sprouts, washed and trimmed
Salt and pepper
1 1/2 cups, or 6 ounces, pancetta in small dice
3 tablespoons minced shallots
1 tablespoon minced garlic
1/2 cup balsamic vinegar
1 1/2 cups veal stock, rich chicken or vegetable broth, more if needed
2 tablespoons chopped parsley

1. Heat oven to 350°F. In a bowl, mix bread crumbs and thyme with some olive oil, and spread on a cookie sheet. Toast, tossing frequently, until golden brown, 10 to 12 minutes.

2. Heat butter and remaining olive oil in a large skillet over medium-high heat until foamy. Add brussels sprouts, sprinkle with salt and pepper, and sauté, tossing frequently, until lightly browned, about 7 to 10 minutes. Add diced pancetta, and sauté, tossing frequently, until sprouts are well browned and softened slightly, and pancetta is crisp, about 10 to 15 minutes more. Reduce heat, add shallots and garlic, and sauté until fragrant, 2 minutes.

3. Increase heat to high, add balsamic vinegar and stock, and cook, tossing frequently, until sprouts are glazed and tender, about 20 minutes; add more stock if needed. Taste, adjusting seasoning if necessary, and sprinkle with chopped parsley. Transfer to a warm serving bowl and scatter bread crumbs on top.
