How to Make It
Preheat oven to 425°F. Scoop seeds from squash cavities; discard.
Place squash halves, cut side up, on a large rimmed baking sheet. Drizzle with oil, and sprinkle with salt and pepper. Flip squash halves over.
Roast squash in preheated oven, cut side down, until fork tender, 40 to 45 minutes. Cut each squash half into 2 slices.
