Ingredients

Scale

Butternut Squash Filling

  • 2 cups butternut squash puree (about half of squash)
  • 1 cup ricotta cheese
  • ½ cup milk or more, if needed
  • ¼ teaspoon salt plus ⅛ teaspoon more
  • ¼ teaspoon nutmeg

Spinach Filling

  • 8 oz spinach (1 cup cooked spinach)
  • 1 cup ricotta cheese
  • 1 cup mozzarella cheese
  • 2 garlic cloves minced
  • ¼ teaspoon salt
  • pepper to taste

Other Ingredients

  • 10 oz lasagna noodles cooked (for gluten free, use Tinkyada brown rice lasagna noodles)
  • 1 ½ cups mozzarella cheese or more
  • ½ cup Parmesan cheese on top
  • ¼ teaspoon Italian seasoning
  • ¼ teaspoon Paprika
  • ¼ teaspoon Basil


Instructions

  1. Preheat Oven: Preheat your oven to 375 degrees Fahrenheit to prepare for baking the lasagna.
  2. Prepare Butternut Squash Filling: Combine 2 cups of butternut squash puree with 1 cup ricotta cheese, ½ cup milk, ¼ teaspoon salt, and ¼ teaspoon nutmeg in a food processor or mixing bowl. Mix until creamy, adding more milk if needed to achieve a smooth consistency. Taste and adjust salt if necessary.
  3. Prepare Spinach Filling: Mix cooked spinach with 1 cup ricotta cheese, 1 cup mozzarella cheese, 2 minced garlic cloves, ¼ teaspoon salt, and pepper to taste. Stir well and adjust seasoning as needed.
  4. Cook Lasagna Noodles: Bring a large pot of water to a boil and cook the lasagna noodles according to package instructions. Rinse in cold water and drain. Trim noodles with a knife if needed to fit your baking dish.
  5. Assemble the Lasagna - First Layer: Lightly grease an 11x8.5x3 inch casserole dish with olive oil spray. Spread one-third of the butternut squash filling evenly on the bottom. Sprinkle lightly with mozzarella cheese, then arrange cooked lasagna noodles (about 3 noodles) on top without overlapping.
  6. Second Layer: Spread half of the spinach filling over the noodles, then sprinkle lightly with mozzarella cheese. Add another layer of cooked noodles on top.
  7. Third Layer: Spread another one-third of the butternut squash filling, sprinkle lightly with mozzarella cheese, and add another layer of noodles.
  8. Fourth Layer: Spread the remaining half of the spinach filling over the noodles, sprinkle lightly with mozzarella cheese, and top with the final layer of noodles.
  9. Top Layer: Spread the remaining one-third of the butternut squash filling over the final noodles. Sprinkle with ½ cup mozzarella cheese and ½ cup grated Parmesan cheese. Generously sprinkle Italian seasoning, paprika, and basil over the cheese.
  10. Bake Covered: Cover the baking dish with foil and bake in the preheated oven for 30 minutes.
  11. Finish Baking: Remove the foil and bake for an additional 10 minutes until the cheese is bubbly and lightly browned.
  12. Serve: Allow the lasagna to cool slightly before slicing and serving warm.

Notes

  • Make it GLUTEN-FREE: Use brown rice gluten-free lasagna noodles and follow the recipe instructions as-is.
  • How to use NO-BOIL LASAGNA NOODLES: If using no-boil noodles, add about ½ cup of milk, water, or vegetable stock to the butternut squash puree to keep the layers moist. Bake 10 extra minutes as needed.
  • How to make it VEGAN: Substitute vegan Parmesan and mozzarella cheeses and use vegan ricotta made from tofu and lemon juice.
