Creating Butternut Squash and Spinach Lasagna involves several steps, but following this guide will help you achieve the perfect dish:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Noodles: Cook the lasagna noodles according to package instructions. Drain and set aside.
3. Sauté the Squash: In a skillet, heat olive oil over medium heat. Add diced butternut squash and cook for about 10-15 minutes until tender.
4. Add Garlic and Spinach: Stir in minced garlic and chopped spinach. Sauté for 2-3 minutes until the spinach wilts. Season with salt, black pepper, and Italian seasoning.
5. Mix Ricotta: In a bowl, combine ricotta cheese, egg, and half of the Parmesan cheese. Mix well until smooth.
6. Assemble the Layers: In a baking dish, spread a thin layer of marinara sauce on the bottom. Place three lasagna noodles over the sauce.
7. Layer Ingredients: Spread half of the ricotta mixture over the noodles, followed by half of the butternut squash and spinach mixture. Sprinkle with one-third of the mozzarella cheese.
8. Repeat Layers: Add another layer of marinara sauce, three more noodles, the remaining ricotta mixture, the remaining veggie mixture, and another third of the mozzarella.
9. Top Everything: Add the final layer of noodles. Cover with marinara sauce, the remaining mozzarella, and the rest of the Parmesan cheese.
10. Cover and Bake: Cover the baking dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 20 minutes until cheese is bubbly and golden.
11. Cool Before Serving: Allow lasagna to cool for 10–15 minutes before slicing to let the layers set.

By following these steps correctly, you’ll create a scrumptious butternut squash and spinach lasagna that everyone will appreciate!
