  • 2 cups ricotta cheese
  • ½ cup milk
  • ¼ tsp nutmeg
  • ½ yellow onion, diced

  • 12 oz baby spinach
  • 1 lrg egg
  • 3 cups mozarella cheese, grated
  • 9 lasagna noodles, cooked al dente

Instructions
 

Prepare Squash:

  • Preheat oven to 375°.
  • Place butternut chunks on a baking sheet and toss with with olive oil to coat. Season with salt and pepper and bake until soft, about 30 minutes.
  • Once squash has cooled, place in a food processor and puree until smooth.
  • Add 1 cup ricotta cheese, ¼ tsp nutmeg, ½ cup milk, and season with salt and pepper. Process until the mixture is smooth and creamy. Set aside.

Prepare Spinach:

  • Heat olive oil in a large skillet. Sauté onion until soft and translucent, about 3-4 minutes. Add the minced garlic and cook 1 minute more until fragrant.
  • Add spinach a handful at a time and cook until wilted.
  • Season with salt and pepper.
  • Continue to cook until most of the liquid has cooked off.
  • Remove from heat and transfer to a large bowl. Using a paper towel, blot up any excess liquid.
  • Add 1 cup ricotta cheese, 1 1/2 cups mozzarella cheese, and egg. Stir well until combined. Set aside.

Assemble Lasagna:

  • Generously grease a 7" X 11" oven safe casserole dish.
  • Spoon some of the squash mixture in the bottom of prepared baking dish. Spread out evenly.
  • Top with 3 cooked lasagna noodles.
  • Top with 1/2 the spinach mixture, and spread out as evenly as possible.
  • Top spinach layer with a generous layer of the squash mixture.
  • Repeat layers ending with a layer of lasagna noodles.
  • Top noodles with remaining 1½ cups shredded mozzarella cheese and ½ cup grated parmesan cheese.

Bake Lasagna:

  • Cover casserole dish with foil. Spray foil with non-stick cooking spray to prevent cheese from sticking to it.
  • Bake lasagna at 375° covered for 50-60 minutes, or until completely heated through.
  • Remove foil and turn on broiler. Broil for 3-4 minutes until cheese is bubbly and lightly browned along the edges. Keep a close eye on it so it doesn't burn.
  • Cut lasagna into generous sized squares to serve.

Notes

For the meat lovers in the family, place Italian sausages on a foil lined cookie sheet and bake alongside the lasagna in the oven.  Slice and serve as a side with the lasagna.
