Step 1

Preheat the oven to 425 degrees F.

Step 2

Trim both ends off the squash and remove the skin with a vegetable peeler. Cut the squash in half lengthwise with a large, sharp knife. Scoop out the seeds with a spoon. Cut the squash halves crosswise into 1-inch thick half-moons, then dice into 1-inch pieces. (A 3-pound squash will yield about 7 cups.)

Step 3

Place the diced squash, olive oil, 1 teaspoon salt and 1/2 teaspoon black pepper in a large bowl. Toss to coat evenly. Spread the squash in a single layer on a rimmed baking sheet. Roast for 35 to 40 minutes, until the squash is lightly browned and tender, turning once with a metal spatula.
