1Preheat oven to 500°F with rack in upper third position.
2Using a vegetable peeler, peel skin from 1 squash and discard.
3Slice the neck of the squash into 1-inch-thick rounds.
4Slice the bulb in half lengthwise; remove and discard seeds.
5Slice each half into 1-inch-thick half-moons.
6Combine the squash, the melted butter, 1 tablespoon oil, ½ teaspoon salt and ½ teaspoon pepper in a large bowl; toss to coat.
7Arrange in a single layer in a 9-by-13-inch metal baking pan.
8Roast, flipping once, until browned around the edges and almost tender, about 25 minutes.
9Meanwhile, whisk ⅓ cup broth, 1½ tablespoons maple syrup, 1 tablespoon vinegar and 1 teaspoon mustard together in a glass measuring cup.
10Carefully add the broth mixture to the pan.
11Continue roasting until most of the liquid has been absorbed and the squash is very tender, about 8 minutes more.
12Transfer the squash to a serving platter.
13Spoon the remaining pan liquid over the squash.
14Garnish with thyme, if desired.
