Mashed Butternut Squash and Sweet Potato
- 3 pounds butternut squash
- 2 pounds sweet potatoes
- ½ tablespoon olive oil
- 1 teaspoon salt, plus a pinch for roasting butternut squash
- ½ teaspoon freshly ground black pepper, plus a pinch for roasting butternut squash
- ½ cup unsalted butter, melted
- ½ to 1 teaspoon pumpkin spice, depending on how pronounced you want the pumpkin spice flavour to be
- Chopped chives, green onion or parsley, garnish to taste (optional)
- Crispy sage leaves, garnish to taste (optional)
- Preheat oven to 400 degrees Fahrenheit.
- Carefully cut butternut squash in half, lengthwise. Scoop out seeds. You can discard or reserve them for another use.
- Clean sweet potatoes, then prick them with a knife a bunch of times in preparation for baking.
- Line a baking sheet with parchment paper. Drizzle olive oil over each half of the butternut squash and sprinkle with a pinch each of salt and black pepper. Place cut side down onto prepared baking sheet. Place sweet potatoes on there too.
- Cook for 45 minutes to 1 hour or so or until both butternut squash and sweet potatoes are tender all the way through when pierced with a knife. Note: If the butternut squash, for example, is cooked before the sweet potatoes, you can remove and continue cooking the sweet potatoes.
- Once everything is cooked, carefully remove from the oven and allow to cool until you can handle it.
- Once everything is cool enough to handle, scoop out flesh from the butternut squash. Cut potatoes in half and scoop out flesh. Place into a large bowl. Roughly mash. (You can discard the skins.)
- Melt butter in a saucepan on the stovetop or in a microwave-safe dish in the microwave until just melted and warmed through. Add 1 teaspoon of salt, ½ teaspoon of black pepper and pumpkin spice, stirring to combine.
- Pour melted butter mixture over butternut squash and sweet potato and mash again. Transfer to a serving dish. Garnish, if desired, with chopped chives and crispy sage leaves. Serve and enjoy!
