For the butternut squash sauce:
Preheat oven to 425 degrees. Prepare a large baking sheet with parchment paper.
Peel the butternut squash with a potato peeler. Then chop the squash in bite sized chunks, removing the seeds. Place the squash on the baking sheet, and drizzle with olive oil, salt, and pepper. Bake for 30 minutes, or until cooked through (fork tender). Remove from oven and cool slightly.7-8 cups cubed butternut squash, 2 Tablespoon olive oil, kosher salt and freshly ground black pepper
Spoon the cooked squash into a blender or food processor. Add in the milk and pulse until smooth. Add additional milk if needed to thin the sauce more. Place in bowl and add in the ricotta cheese, nutmeg, and additional salt and pepper as needed.3/4-1 cup milk, 1 cup ricotta cheese, 1 teaspoon nutmeg
For the spinach and cheese layer:
While the squash is baking, prepare spinach and cheese layer. Over medium heat, saute spinach and garlic in some olive oil until spinach is wilted, approximately 3-4 minutes. Add salt and pepper to taste. (Reserve a little bit of wilted spinach for the top of the lasagna, if desired.)1 Tablespoon olive oil, 4 cups spinach leaves, 2 cloves garlic, kosher salt and freshly ground pepper

To assemble, spoon some of the squash sauce on the bottom of a 9x9 dish. Lay lasagna noodles on top (cutting off a couple of inches if needed to fit), followed by 1/3 of the spinach and cheese mixture, followed by 1/3 of the butternut squash puree. Repeat until all ingredients are used - three layers. Then top with the remaining mozzarella cheese and parmesan cheese.
