A delicious cozy recipe, for Butternut Lasagna – full of fall flavors. And it’s easily made vegan! Butternut squash is roasted in the oven and becomes the silky sauce that infuses the lasagna with such goodness. I know you will love it! Perfect for vegan thanksgivings.

This week I’m so excited to be partnering with Beaujolais Wine to help share how versatile and lovely the wines from the region are, while being very affordable and approachable. The perfect wine to bring to your Thanksgiving day gathering!

Beaujolais, in case you’re unfamiliar, is a region in France located just south of Burgundy with gentler, milder temperatures. Wine here most often is produced from Gamay grapes, which have thin skins, low tannins, and makes for a light, drinkable everyday red that is friendly on the palate, and pairs well with many dishes. Beaujolais also comes in white and rosé -which I actually didn’t know but am so excited to try!

Butternut Lasagna starts with a roasted butternut puree, which becomes the “sauce”. You could roast this off the night before and cool in the fridge until ready to assemble. Or cook the butternut whole, in a instant pot for 22 mintues.

I use uncooked lasagna noodles to save time- such a godsend!

Layer with ricotta and mushrooms, shallots and sage…..or substitute this vegan tofu ricotta!

For extra luxuriousness, drizzle with a little optional, but tasty, truffle oil.

You’ll repeat the layers a couple of times and then bake!

Top the butternut lasagna with cheese for added richness if you like, keeping in mind all the amazing “meltable” vegan cheese out there these days.

Sometimes, instead of adding a final layer of grated cheese, I’ll make a light, quick béchamel sauce…. purely because I prefer the look of it ( from my catering days) compared to the grated cheese “look”. See recipe notes for more info. 🙂

When the Butternut lasagna comes out of the oven it will smell heavenly. Beautifully golden and fragrant!

For a special dinner,  an added touch is to make crispy sage leaves as a garnish over the butternut lasagna.  You could also drizzle with your favorite pesto, for a little color. Both optional.

So hearty and delicious! Serve the butternut lasagna with a tasty fall salad and you have a yummy meal!

Hope your Thanksgiving is beautiful….. and you enjoy this Butternut lasagna! I know for sure, you will love the leftovers.

Cheers friends!

xoxo

• ½ a sweet onion, sliced into big wedges
• olive oil for drizzling

• 2 tablespoons olive oil or butter
• 1 ½  lb mushrooms, sliced

• 2 tablespoons fresh chopped sage
• ½  teaspoon salt
• optional – feel free to add a couple of handfuls baby spinach or greens and wilt them.

• one egg (optional)
• ½ teaspoon nutmeg
• ½ teaspoon salt

Butternut Puree:

• 3 tablespoons olive oil
• 3–6 tablespoons water
• 1 teaspoon salt
• ½ teaspoon pepper
• ½ teaspoon garlic powder

---

• 1 1 /2 cups grated mozzarella cheese ( about 3–4 ounces) or sub vegan “meltable” cheese
• ½ cup romano or parmesan ( about 1 ounce) or sub vegan
• 9 lasagna noodles (uncooked)
• Garnish with 9 crispy sage leaves (optional, see notes)

Optional Quick Béchamel Sauce:

• 1 1/2 tablespoons olive oil (or butter)
• 1 ½ tablespoons flour
• 1 cup milk ( or nut milk)
• generous pinch salt, pepper and nutmeg
• remaining ½ cup mozzarella and 2 tablespoons parmesan (or meltable vegan cheese )

Instructions

START THE BUTTERNUT. 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.

Lower oven to 375F

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.

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.)

Make the BUTTERNUT SAUCE: When the butternut is cool enough to handle, scoop all the flesh out into a food processor. You should have about 4 cups. Add the roasted onion, olive oil, water, salt, pepper and garlic powder. Puree until smooth. You will need at least 3 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”.

Assemble the lasagna. In a greased 9 x13 inch baking dish, 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 cook 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 ¼ cups for the top.) Add the remaining mushrooms and all the good bits ( onions and sage) and 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.

Notes

Optional Béchamel: So instead of sprinkling the remaining cheese on top (which is totally fine, especially if pressed for time) I’ll make a quick light béchamel sauce to pour over the final layer of butternut puree using the remaining cheese. This just gives it a creamier look and feel (compared to the look of melted, grated cheese). This is just a personal preference, that makes it look more appealing (from my catering days).  Totally up to you. 😉

To make the bechemel: heat the oil or butter in a small pot over medium heat. Add the flour, and toast it for 1-2 minutes. Gradually whisk in the milk, whisking out any clumps and browned bits. Stir in salt, pepper and cheese, stirring until melted and incoporated.

A great way to conquer this is to make the compenents in stages. Make the butternut puree one day, the filling the next (storing in the fridge) assembling the next day, baking the next etc. OR Feel free to make this all ahead (refrigerate) and bake before serving, remembering to pull it out of the fridge for at least one hour before baking to let it come to room temp, for even baking.

This can also be baked and frozen.

To make the crispy sage leaves, generously coat the bottom of a small skillet with  olive oil over medium heat. Place each leave ( leaving a little stem is cute) into the hot oil and fry each side, around 30 seconds, or until crisp. Place on a paper towel to blot. Do one tester first, to get the timing right. You want them crisp, but still green, not too brown.)
