In a large bowl, toss the cubed butternut squash with chopped onion, minced garlic, olive oil, sage, nutmeg, salt, and pepper until evenly coated.
Spread the mixture in a single layer on a baking sheet.
Roast for 40-50 minutes, or until the squash is tender and lightly caramelized, flipping halfway through.
Once tender, transfer the roasted squash and onion mixture to a blender or food processor. Add the vegetable broth and blend until smooth and creamy. Add more broth if needed to reach desired consistency.
Serve hot as a flavorful side dish.
Notes
This creamy butternut squash puree is a delicious and healthy alternative to traditional Thanksgiving sides. Feel free to add a pinch of cinnamon or ginger for extra warmth.
