Ingredients

  • 1 medium butternut squash (about 2 ½ lbs), peeled, seeded, and cubed
  • 2 tablespoons unsalted butter
  • ¼ cup milk or cream (adjust for consistency)
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 1 tablespoon maple syrup or brown sugar (optional, for sweetness)
  • ¼ teaspoon ground cinnamon or nutmeg (optional)

Instructions

  1. Preheat the oven to 400°F (200°C).
  2. Peel and cube the butternut squash into evenly sized pieces.
  3. Toss the squash with olive oil, salt, and pepper, then spread it on a baking sheet in one layer.
  4. Roast for 25–30 minutes, flipping halfway through, until tender and caramelized at the edges.
  5. Transfer roasted squash to a large bowl and mash using a masher, fork, or immersion blender.
  6. Stir in butter, milk, and any additional seasonings while still warm until smooth and creamy.
  7. Adjust salt and pepper to taste, then serve warm as a side dish.

Notes

  • Roasting brings out the best flavor and prevents a watery texture.
  • Use warm milk and butter for a smoother mash.
  • For a savory version, add garlic, herbs, or Parmesan cheese.
  • For a sweet version, mix in maple syrup, cinnamon, or nutmeg.
  • Can be made vegan by using plant-based butter and milk alternatives.
