Step-by-Step Instructions

Step 1: Roast the Butternut Squash

1. Preheat your oven to 400°F (200°C).
2. Toss the cubed butternut squash with olive oil, salt, and black pepper.
3. Spread on a baking sheet and roast for 25-30 minutes until soft and caramelized.
4. Blend the roasted squash in a food processor or blender until smooth. Set aside.

Step 2: Caramelize the Onions & Sauté the Mushrooms

1. In a large skillet, add olive oil over medium-low heat.
2. Add sliced onions and cook for about 30-40 minutes, stirring occasionally, until golden brown.
3. Add the mushrooms, salt, and pepper. Cook for another 5-7 minutes until the mushrooms are tender. Set aside.

Step 3: Prepare the Ricotta Mixture

1. In a medium bowl, mix ricotta, Parmesan, parmesan cheese, mozzarella cheese, chili flakes, grated garlic, wilted spinach, parsley, salt, and pepper.
2. Stir until well combined and smooth.

Step 4: Assemble the Lasagna

1. Preheat your oven to 375°F (190°C).
2. Spread a thin layer of the butternut squash puree at the bottom of a greased 9×13-inch baking dish.
3. Layer 4-5 lasagna noodles over the squash.
4. Spread half of the ricotta mixture, followed by half of the caramelized onions and mushrooms. Then add the mozzarella and parmesan cheese.
5. Repeat the layers: butternut squash puree, noodles, ricotta mixture, onions & mushrooms, and cheeses.
6. Top with the remaining noodles and spread any leftover squash puree on top.
7. Sprinkle mozzarella and Parmesan cheese over the top.

Step 5: Bake the Lasagna

1. Cover the dish with aluminum foil and bake for 30 minutes.

3. Let the lasagna rest for 10 minutes before slicing and serving.
