Ingredients

1 1/4 pounds parsnips

1 1/4 pounds sweet potatoes, quartered lengthwise, then cut diagonally into 1/2-inch pieces

2 tablespoons olive oil

Coarse salt and ground pepper

2 tablespoons pure maple syrup

1 tablespoon Dijon mustard

Chopped parsley, (optional)

Preparation

Preheat oven to 450 degrees. Peel and cut parsnips as directed above; then cut on a diagonal into 1/2-inch-thick pieces.

On a large rimmed baking sheet (or two smaller baking sheets), toss parsnips and sweet potatoes with oil; season generously with salt and pepper. Spread in a single layer. Roast until tender and golden, tossing once or twice, about 30 minutes. Transfer to a large bowl.

In a small bowl, stir together maple syrup and mustard. Pour over vegetables; toss to coat. Sprinkle with parsley, if desired. Serve immediately.
