01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper.
02 - In a large mixing bowl, combine cubed butternut squash with olive oil, ground cinnamon, sea salt, and black pepper. Toss until all pieces are evenly coated.
03 - Spread seasoned squash in a single layer on the prepared baking sheet, maintaining adequate spacing between pieces to ensure even roasting.
04 - Roast for 25 to 30 minutes, turning once halfway through cooking, until squash is tender with golden brown edges.
05 - Remove from oven. If desired, drizzle with honey or maple syrup and gently toss to combine.
06 - Transfer roasted squash to a serving dish. Sprinkle with fresh herbs if using. Serve immediately while warm.
