First, cut the squash. Because you can eat the skin, there’s no need to peel the squash before you chop it. Start by slicing it in half lengthwise. Then, use a spoon to scoop out the seeds and the stringy flesh. Finally, cut the seeded squash halves into thick slices.
Next, season it. Drizzle the chopped squash with olive oil, and season it with salt and pepper. Toss to coat, and spread it in a single layer on a parchment-lined baking sheet.
Finally, bake! Transfer the baking sheet to a 425° oven and bake for 20-25 minutes, until the squash is completely tender and golden brown.
