01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper.
02 - In a large bowl, toss the butternut squash cubes with olive oil, salt, and pepper until evenly coated.
03 - Spread the squash in a single layer on the prepared baking sheet. Roast for 30–35 minutes, turning halfway, until golden and tender.
04 - While the squash is roasting, melt the butter in a small skillet over medium heat. Add the sage leaves and cook, stirring, until the butter turns golden brown and the sage becomes crispy (about 2–3 minutes). Remove from heat.
05 - Transfer the roasted squash to a serving bowl. Drizzle with the sage butter and gently toss to coat. If desired, drizzle with maple syrup or honey for sweetness and sprinkle with Parmesan cheese. Serve warm.
