How to Make Italian Butternut Squash and Spinach Lasagna

Prepare the Butternut Squash Mixture

Combine mashed butternut squash, ricotta cheese, milk, salt, and nutmeg in a food processor. Blend until creamy, adding more milk if needed. Taste and adjust salt if necessary. Set aside.

Prepare the Spinach Filling

In a mixing bowl, combine cooked and drained spinach with ricotta, shredded mozzarella, minced garlic, salt, and black pepper. Mix thoroughly. Optionally, add a squeeze of lemon juice to brighten the flavor.

Cook the Noodles

Bring a large pot of water to a boil. Cook lasagna noodles according to package instructions until al dente. Rinse in cold water and drain well. Trim noodles to fit your baking dish if necessary.

Layer the Lasagna

Preheat oven to 375°F. Grease an 11 x 8.5 x 3-inch baking dish with olive oil or non-stick spray. Begin layering:

1. Spread ⅓ of the butternut squash mixture on the bottom. Sprinkle lightly with mozzarella.
2. Add a layer of noodles without overlapping.
3. Spread half of the spinach mixture, sprinkle lightly with mozzarella, then add another layer of noodles.
4. Spread another ⅓ of the butternut squash mixture, sprinkle mozzarella, and layer noodles again.
5. Spread the remaining spinach mixture, top with mozzarella, and add the final noodle layer.
6. Spread the last ⅓ of the butternut squash mixture over the top layer. Sprinkle with Parmesan, remaining mozzarella, Italian seasoning, paprika, and dried basil.

Bake the Lasagna

Cover the baking dish with foil and bake at 375°F for 30 minutes. Remove the foil and bake uncovered for an additional 10 minutes, or until the cheese is golden and bubbling. Let the lasagna rest for 10 minutes before slicing to help the layers set.

Tips for Success

• Make sure spinach is well-drained to prevent a watery lasagna.
• Use a food processor for the squash mixture to achieve a smooth, creamy texture.
• Resting the lasagna after baking ensures clean slices.
• Adjust seasoning of each layer individually to ensure a balanced flavor throughout.

Equipment Needed

• Food processor (for squash mixture)
• Large pot (for boiling noodles)
• 11 x 8.5-inch baking dish
• Mixing bowls
• Knife and cutting board

Recipe Variations

• Gluten-Free: Use brown rice or gluten-free lasagna noodles.
• Vegan: Substitute ricotta with cashew cream, mozzarella with vegan cheese, and milk with plant-based milk.
• Spicy Twist: Add a pinch of red pepper flakes to the spinach layer for subtle heat.
• Extra Veggies: Incorporate roasted zucchini, mushrooms, or bell peppers in the spinach layer.
