Ingredients

1 3/4 pounds white turnips, peeled and cut into pieces 2 1/2 inches by 1 1/2 inches in size

1 3/4 pounds golden turnips or rutabagas, peeled, cut into pieces 2 1/2 inches by 1 1/2 inches in size

10 shallots (about 10 ounces), peeled, root end intact

2 tablespoons plus 2 teaspoons extra-virgin olive oil

Coarse salt and freshly ground pepper

3/4 cup red-wine vinegar

2 bay leaves

6 sprigs fresh thyme

1/4 cup packed light-brown sugar

3 tablespoons unsalted butter

Preparation

Preheat oven to 400 degrees. Put turnips, shallots, and oil on a rimmed baking sheet. Season with salt and pepper; toss. Spread in a single layer. Roast until tender and golden brown, about 35 minutes.

Put vinegar, bay leaves, and thyme in a small saucepan. Bring to a simmer; cook until reduced by about half, about 10 minutes. Add sugar and 1/2 teaspoon salt; stir to dissolve. Add butter, and cook over medium heat until reduced to a syrupy glaze, about 10 minutes. Discard thyme. Pour over roasted vegetables; toss to coat. Serve immediately.
