Prepare the Vegetables: Begin by peeling and thinly slicing the sweet potatoes, butternut squash, and carrots into even rounds, about ¼ inch thick.

Assemble the Layers: Start layering your ingredients in a greased baking dish, beginning with sweet potatoes, followed by butternut squash, carrots, feta cheese, and walnuts, repeating until all ingredients are used.

Drizzle with Glaze: Generously drizzle the cranberry honey glaze over the top layer of the lasagna.

Bake the Lasagna: Cover the dish with aluminum foil and bake at 375°F (190°C) for 55 minutes, then remove the foil and continue baking for an additional 15 minutes.

Cool and Serve: Let the lasagna cool for about 10 minutes before serving.
