01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, toss the butternut squash cubes with maple syrup, olive oil, cinnamon, sea salt, and black pepper until evenly coated.
03 - Spread the glazed squash in a single layer on the prepared baking sheet and roast for 25 minutes, stirring once halfway through to ensure even cooking.
04 - Meanwhile, combine pecans, walnuts, pumpkin seeds, maple syrup, melted butter (or coconut oil), and a pinch of sea salt in a small bowl, mixing thoroughly.
05 - Remove the squash from the oven, evenly sprinkle the nut mixture over the top, then return to the oven and bake an additional 10 minutes until nuts are golden and squash is tender.
06 - Transfer to a serving platter and serve immediately while warm.
