Arrange the sliced butternut squash, sweet potato, and potato in a pattern horizontally in the skillet (see the process photos for clarification).
1 medium butternut squash, 2 medium sweet potatoes, 2 medium Yukon Gold or russet potatoes
Pour over the warmed cream, ensuring it seeps into all the layers.
Cover the skillet with foil and bake for 45 minutes. Remove the foil, sprinkle the reserved cheese over the top, and bake for an additional 20-25 minutes, or until the top is golden brown and the vegetables are tender when pierced with a knife.

You can easily prep this recipe ahead of time - either slice the potatoes and store in an airtight container, or cover the vegetables in the cream, cover them tightly with foil, and then pop them in the oven when you're ready to cook.
