Butternut Squash Lasagna with Mushrooms and Sage

Butternut squash

Preheat oven to 425 F. Cut butternut squash in half, scoop out the seeds and place open side down on a parchment lined baking sheet. Place sliced onion next to it and drizzle it with a little olive oil. Roast until fork tender, about 30-40 minutes. Let cool. You could do this a day before.

When the butternut is cool enough to handle, scoop all the flesh out into a food processor. You should have about 5 cups. Add the roasted onion, olive oil, water, salt, pepper and garlic powder. Puree until smooth. You will need at least 4 1/2  cups pureed and you want it to be almost saucy, like a marinara sauce ( so add water if need be!). This will act as the “sauce”.

Mushroom filling

Make the mushroom filling. In a large skillet, heat the oil or butter. Add mushrooms and shallots and salt, and saute over medium heat, until the mushrooms release their liquid and begin to brown. Add the garlic, sage and pepper.  Cook until garlic is fragrant, about 2-3 more minutes, turn heat off. You could toss in some spinach at the end and wilt for extra nutrients. Taste and make sure the filling has enough salt and pepper. You could also add a little truffle oil. You could make this 1-3 days ahead and refridgerate.

Ricotta Mixture

If you can use a 1 1/2 to 2x recipe for this. Using a fork, mix the ricotta cheese with the egg, nutmeg and salt. ( You really don’t have to add the egg, but it adds a nice richness.) vegan tofu ricotta link.

Assembly

• Preheat oven to 375F
• parboil lasagne noodles one layer at a time
• Add 1 cup of the butternut puree and spread out into a thin layer. 
• Top with 3 lasagna noodles. 
• Add ½ of the ricotta mixture and spread out evenly. 
• Top with half of the cooked mushrooms. 
• Sprinkle with ½ cup grated mozzarella and a couple tablespoons romano cheese. 
• Add 3 more lasagna noodles. 
• Spread out the rest of the ricotta mixture as evenly as possible. 
• Spoon half of the remaining butternut puree, erring on the side of less than half, so you have enough to cover the top (save at least 1 3.4 cups for the top.) 
• Add the remaining mushrooms and all the good bits ( onions and sage) 
• Sprinkle with another ½ cup shredded mozzarella and couple tablespoons parmesan. 
• Place the final three noodles over the top. 
• Lather with the remaining butternut puree and 
• Sprinkle with the rest of the cheese ( or make the creamy béchamel sauce.- See notes. ) You could assmeble this 1-2 days before baking.

Cover tightly with foil and bake in 375 F oven for 40 minutes. (If the foil touches the lasagana, place a layer of parchment beween the foil and lasagna). Uncover and continue baking 15-20 minutes until golden and bubbly. Cut into 9 servings. Garnish with optional crispy sage leaves.
