Creating Butternut Squash & Spinach Lasagna can be straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Cook the Noodles: Boil the lasagna noodles in salted water according to package instructions until al dente. Drain and set aside.
3. Prepare the Squash: In a large pot, heat olive oil over medium heat. Add the cubed butternut squash and sauté until tender, about 10-15 minutes. Season with garlic powder, onion powder, salt, and pepper.
4. Combine Spinach: Add the chopped spinach to the pot and cook until wilted. Remove from heat and let cool slightly.
5. Mix the Cheese: In a bowl, combine the ricotta cheese, half of the mozzarella, and grated Parmesan. Mix well and season with salt and pepper.
6. Layer the Ingredients: In a baking dish, spread a thin layer of marinara sauce on the bottom. Place three lasagna noodles on top.
7. Add Filling: Spread half of the ricotta mixture over the noodles, followed by half of the butternut squash and spinach mixture. Repeat the layers, finishing with noodles and sauce on top.
8. Top with Cheese: Sprinkle the remaining mozzarella cheese over the final layer of sauce.
9. Cover and Bake: Cover the dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the cheese is bubbly and golden.
10. Cool and Serve: Remove from the oven and let cool for 10-15 minutes before slicing and serving.
