Preheat your oven to 375°F (190°C).
Cut the autumn frost squash in half, scoop out the seeds, and slice it into wedges.
In a mixing bowl, combine the olive oil, salt, pepper, cinnamon, nutmeg, allspice, and maple syrup.
Toss the squash wedges in the mixture until well coated.
Arrange the squash on a baking sheet and roast for about 40 minutes or until tender and caramelized.
Garnish with fresh thyme leaves before serving.
