1First steam the butternut squash until soft (about 8-10 minutes) then gently add the squash to a large bowl and mash with oil, salt and garlic powder so it is “puree” form
2Preheat oven to 375 degrees F and take out an 9×13 baking dish
3Next make the ricotta filling by adding 1 tablespoon chopped sage, lemon zest, nutmeg, ricotta cheese, salt and pepper and milk to a medium bowl and mix
4In your baking dish, spread ½ cup ricotta sauce on the bottom of the pan and then top with 1 layer of noodles, ½ of the cooked squash, mushrooms kale, scant 2/3 cup cheese sauce, 1 cup mozzarella and ⅓ cup parmesan cheese
5Then repeat again and finally, top with noodles then the remaining ricotta sauce spread with a spatula
6Sprinkle the entire top with the remaining cheese and sage
7Next cover the pan with aluminum foil and bake for 40 minutes
8Carefully remove the foil and bake another 20 minutes, until the top is browned
Let stand for 5 to 10 minutes before serving
