Bake
Cover with foil and bake for 30 minutes. Remove foil and bake for an additional 20–25 minutes until vegetables are tender and the top is golden and bubbly.
Cool & Serve

❓ Frequently Asked Questions
Do the beets need to be cooked first?
No—slicing them thinly allows them to cook fully in the oven alongside the sweet potatoes.
Can I use frozen vegetables?
Fresh is preferred for best texture and flavor.
Is this sweet or savory?
It’s a balance of both—the maple adds sweetness while the cream, cheese, and seasoning keep it savory and rich.
