Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
Prepare the squash by slicing it in half and scooping out the seeds. Peel the skin if preferred. Cut into wedges or cubes.
Season the squash by tossing it in a bowl with olive oil, salt, black pepper, cinnamon, and garlic powder. Drizzle with maple syrup for extra sweetness.
Arrange on the baking sheet in a single layer to ensure even roasting.
Bake for 25–30 minutes, flipping halfway through, until the squash is tender and slightly caramelized.
Garnish with fresh herbs and serve warm as a side dish or over salads and grain bowls.
