Some believe its roots trace back to ancient Greece, where they crafted layered dough sheets, known as “laganon,” sliced into strips and baked to perfection. Others point to a Roman dish mentioned in a 1st-century AD cookbook, while some attribute its creation to England or Italy during the 14th century, with cookbooks describing the novel idea of layering cheese and pasta in a dish and baking it to deliciousness.
What follows is a plant-based take on the timeless pleasure of assembling layers of “cheese” and pasta, then baking them in a casserole dish.

- Salt and pepper to taste
- 2 cups of ricotta cheese
- 1 cup of grated Parmesan cheese
- 2 cups of shredded mozzarella cheese
- 2 cups of fresh baby spinach leaves

Instructions:
Step 1: Roast the Butternut Squash
- Preheat your oven to 375°F (190°C). Place the diced butternut squash on a baking sheet, drizzle with olive oil, and season with salt and pepper. Roast for 25-30 minutes until tender. Set aside.


Step 2: Create Butternut Squash Puree
- In a large skillet, heat up a splash of olive oil over medium heat. Toss in the finely chopped onion and let it dance in the skillet until it turns beautifully translucent. This usually takes about 3-4 minutes. Set it away for later use once completed.
Step 3: Sauté the Onion
In a large skillet, set the heat to medium and let it come to life with a drizzle of olive oil. Sauté the finely chopped onion for 3-4 minutes, or until transparent. Set aside.

Repeat the layers:
- Lasagna noodles
- Ricotta cheese mixture
- Butternut squash puree
- Spinach
- Mozzarella cheese
- Finish with a final layer of lasagna noodles and top with the remaining mozzarella cheese.
Step 6: Bake to Perfection
