Ingredients

Scale

Butternut Squash Filling:

  • 2 cups butternut squash puree (about half of squash)
  • 1 cup ricotta cheese
  • ½ cup milk, 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, for topping
  • ¼ teaspoon Italian seasoning
  • ¼ teaspoon paprika
  • ¼ teaspoon basil


Instructions

  1. Preheat Oven: Preheat your oven to 375°F to prepare for baking the assembled lasagna.
  2. Prepare Butternut Squash Filling: In a food processor, combine 2 cups of butternut squash puree, 1 cup ricotta cheese, ½ cup milk, ¼ teaspoon salt, and ¼ teaspoon nutmeg. Blend until creamy, adding more milk if necessary. Taste and adjust salt as needed.
  3. Prepare Spinach Filling: Mix cooked spinach, 1 cup ricotta cheese, 1 cup mozzarella cheese, minced garlic, ¼ teaspoon salt, and pepper to taste in a bowl. Stir well and adjust seasoning if desired. Optionally, add lemon juice or zest for brightness.
  4. Cook Lasagna Noodles: Bring a large pot of water to a boil and cook lasagna noodles according to package instructions. Rinse under cold water and drain. Trim noodles to fit your baking dish if necessary.
  5. Prepare Baking Dish: Lightly grease an 11 × 8.5 × 3 inch casserole dish with olive oil spray to prevent sticking.
  6. Assemble Lasagna - First Layer: Spread one-third of the butternut squash filling evenly on the bottom of the dish. Sprinkle lightly with mozzarella cheese. Lay 3 cooked lasagna noodles on top without overlapping.
  7. Assemble Lasagna - Second Layer: Spread half of the spinach filling over the noodles and top lightly with mozzarella cheese. Add another layer of cooked noodles on top.
  8. Assemble Lasagna - Third Layer: Spread another one-third of the butternut squash filling over the noodles. Sprinkle lightly with mozzarella cheese and layer cooked noodles again.
  9. Assemble Lasagna - Fourth Layer: Spread the remaining half of the spinach filling over the noodles. Top lightly with mozzarella cheese and add the final layer of cooked noodles.
  10. Assemble Lasagna - Final Topping: Spread the remaining one-third of butternut squash filling over the final noodle layer. Sprinkle with Parmesan cheese, remaining mozzarella cheese (about ½ cup), and evenly dust with Italian seasoning, paprika, and basil.
  11. Bake Covered: Cover the baking dish with foil and bake for 30 minutes to heat through and meld flavors.
  12. Bake Uncovered: Remove the foil and bake for an additional 10 minutes to brown the cheese topping.

Notes

  • Gluten-Free Option: Use brown rice gluten-free lasagna noodles and follow recipe instructions as-is.
  • No-Boil Noodle Tip: When using no-boil lasagna noodles, add ½ cup of milk, water, or vegetable stock to the butternut squash puree to maintain creaminess and bake lasagna for an additional 10 minutes.
  • Vegan Modification: Substitute vegan Parmesan and mozzarella cheeses. Make vegan ricotta using tofu and lemon juice for a plant-based version.
  • Spinach Prep: Including lemon juice and zest in the spinach filling brightens flavors but is optional based on preference.
  • Adjust Milk Quantity: Add milk gradually to achieve desired creamy consistency in the squash filling.
