Lightly coat a baking sheet with nonstick spray and set aside.
Prepare the butternut squash by peeling it, removing the seeds and chopping it into chunks. Arrange it into a single layer onto the prepared baking sheet.
Drizzle the cubed squash with olive oil, maple syrup, brown sugar, cinnamon, and nutmeg. Gently toss to combine.
Bake for 25 to 30 minutes, turning once mid-process. The squash should be fork-tender.
