Here’s a delicious vegetarian or vegan main dish, worthy of your holiday table – Butternut Lasagna with Mushrooms and Sage. So comforting and homey.
What I love about this recipe is the butternut lasagna can be made ahead (or in stages) and stored in the fridge until ready to bake. When it comes out of the oven, beautifully golden and bubbly, your house is sure to smell amazing!

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.
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 no-boil 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. I love this with Arugula Pesto!
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

Description
Butternut Lasagna with Wild Mushrooms and Sage, – a delicious vegetarian or vegan main dish, perfect for your holiday table! This can be made ahead, and baked right before serving! Try using Smoked Mushroms!
Ingredients
- Small butternut squash ( 2.5lbs – 3lbs) (you’ll need about 4 cups, roasted)
- ½ a sweet onion, sliced into big wedges
- olive oil for drizzling
Mushroom Filling:
- 2 tablespoons olive oil or butter
- 1 ½ lb mushrooms, sliced (cremini, button, shiitake, portobello, wild mushrooms, etc.)
- 1 fat shallot or ½ onion, diced
- 4 garlic cloves, chopped
- 2 tablespoons fresh chopped sage
- ½ teaspoon salt
- optional – feel free to add a couple of handfuls baby spinach or greens and wilt them.
Ricotta Mixture:
- 1 lb ricotta cheese (or sub vegan tofu ricotta) If using the tofu ricotta, no need to add more salt or egg. Just nutmeg 🙂
- 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
- no-boil lasagna noodles (uncooked)
- Garnish with 9 crispy sage leaves (optional, see notes) or Arugula Pesto
Optional Quick Béchamel Sauce:
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 or cook whole in an instant pot for 22 minutes.
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 the 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 refrigerate.
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 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 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 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 assemble this 1-2 days before baking.
Cover tightly with foil and bake in 375 F oven for 40 minutes. (If the foil touches the lasagna, place a layer of parchment between 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.)

Do you put raw lasagna noodles in this recipe? It doesn’t specify in the recipe instructions.
Yes, raw, uncooked lasagna noodles.
Have made this twice now and EVERYONE loves it!
Thanks for a wonderful recipe.

Thanks so much Marie! Appreciate this! xoxo
This has become one of my go-to fall and winter favorites. I use a sheet pan to roast the squash rubbed with olive oil and a jaime oliver squash spice mix (coriander seed, fennel seed, oregano, a little chili plus salt and pepper, ground up) and 2-4 garlic cloves and in another sheet pan roast the seasoned mushrooms with EVOO, sage or thyme, a sliced onion, a handfull of cherry tomatoes and for the last few minutes some greens (rapini, kale, chard or spinach—just to wilt these). I find the tomatoes and bitter greens contrast well with the sweet rich squash sauce and the mild ricotta & cheeses, and the colors are lovely. Once out of the oven, I blend the squash-garlic with stock or water and make it a little thin because I use either dry “no-cook” or fresh lasagne noodles…so maybe 30 min prep for the ingredients and another 30 min in the still hot oven, and voila, lasagne on a weeknight! Love this brilliant dish. Many thanks Sylvia.

I love that you love this Bri.
This is the BEST lasagna ever! Made it for the holidays & it was a hit over the original meat presentation. The flavor profile is outstanding, with the savory tones.
★★★★★
Great to hear and thanks for sharing!!!
I plan to make this for the holidays. Would it be too much liquid if I boil the lasagna noodles beforehand?
Absolutely amazing- made it for my family this evening and we all went back for seconds and thirds!
★★★★★
Hi, I am going to make this for when family comes over. I was wondering if you bake it first then freeze it or put it in the freezer unbaked and how long can it be frozen?
★★★★★
I think you could do it either way, freeze it baked or unbaked. Just make sure to thaw completely before baking or reheating. It will last 3 months, sealed well.
Made this for my daughter, who is vegetarian, and the whole family loved it! I get lots of butternut squash in my CSA basket, so I am always looking for new ways to use it. This recipe fit the bill perfectly. Delicious!
★★★★★
Thanks Christine, Happy you liked it!
This is a very savory dish that tastes even better a day or 2 later 😀 My neighbor, who has boycotted butternut squash since I’ve known her, was converted by this lasagne.
Love hearing stories like this! Yay, another convert! 😉
Can this be made in advance and frozen?
Yes! For sure.
Absolutely loved It! And bonus was that my husband (always a good sport when I try out new recipes) loved it too!
Oh Sue, great to hear!!!
This dish is soo delicious! I rarely find myself repeating a recipe because I like to try new dishes, but I have made this twice in the last few weeks. I am already craving it and can’t wait to make it a third time soon.
★★★★★
Thanks so much Kari! Im so glad you enjoyed it and appreciate you letting us know!!!
I’m making this and the mushroom wellington for a Thanksgiving dinner being hosted by friends and family,…Forget the bird, bring on the mushrooms!! Both dishes are loaded with flavor and don’t get me started on the wonderful smells coming from my oven!!!
★★★★★
So awesome Karen! Thank you so much! Happy Thanksgiving. xo
I’m looking forward to making this for Thanksgiving in 2 days. I think you forgot to list “shallots” in your ingredients even though it’s mentioned in the article. I didn’t notice this until just after I got home from the grocery store. I might use a little fresh garlic and onions instead. Let me know what you think if you get a chance.
I updated the recipe, thanks!
I recently began a vegetarian diet and found your website – so many amazing recipes I made this dish, and while it is time consuming, it was so worth the effort. May I suggest you add directions for making the bechamel sauce? I needed to go online for instructions. Also, once I followed your baking instructions, I broiled it for a few minutes to brown up the sauce topping. Can’t wait to have leftovers today!
★★★★★
Thanks Michele! Gald you liked it. I added the directions- thank for suggesting!!! Enjoy your leftovers!
It took tremendous willpower not to moan audibly while eating this! It is well worth the effort.
★★★★★
Hahaha, love it!
Delicious and seasonal
★★★★
Oh my goodness this was good. My 5-year-old picky eater loved it! So glad I found a new way to use up garden squash.
★★★★★
Delish….
★★★★★
The butternut in this recipe just transforms the lasagne, the best one I have ever made!!! Thanks Sylvia, another fantastic recipe!!!
★★★★★
yum
Another delicious recipe, Sylvia! Made this with baby bella mushrooms and baby spinach. The roasted sweet onion really adds a depth of flavor to the butternut purée. I like the hint of nutmeg in both the ricotta mixture and the creamy béchamel sauce. And, this reheats nicely for another dinner or two. Thank you!
★★★★★
Served this to my vegetarian niece for Thanksgiving- big hit! After eating, she commented that she loves eating at my house as she always gets something wonderful. Thanks for the recipe.
★★★★★
This makes me so happy! Glad your niece enjoyed it!!!
Yum
Hi Sylvia,
I usually like to follow a recipe as written the first time I make it but this time I changed it up. We have some local wild mushroom companies here in Maine so I went with them. The problem is that a pound and a half of organic wild mushrooms can be a little pricey so I compromised. I used a 50/50 mixture of wild mushrooms and ground lamb sautéed in ghee and I did add one egg to the ricotta mixture. It was delicious. The butternut squash goes quite well with the mushrooms and lamb. I had some leftover and froze it for another day. I’m looking forward to trying some of your recipes you discovered on your recent trip to India. Best wishes for a happy holiday season. Terry
★★★★★
Aww thanks Terry! As always, I love how you adapt recipes to meet your needs. Sounds really delicious!
This was delicious. I made it for a post Thanksgiving dinner for a group of 16, with 2 vegetarians, and it is nearly gone. The bechamel sauce and the crispy sage leaves give it that extra special taste, texture and appearance. Now that I’ve experienced all of the steps, I will have greater future success in a shorter amount of time.
★★★★★
This was delicious! I love not having to cook the noodles. And the extra water in the puree was enough to cook the noodles. Next time I will add a some sage sausage to half of it for the carnivores in the family. Great recipe for butternut squash!
★★★★★
Oh good! Im glad it turned out! Thanks for letting me know…I was starting to worry. 😉
This looks amazing! I am looking forward to making it for Thanksgiving. I don’t eat tofu. Could I use a cashew ricotta in place of the tofu?
I think so ?? I haven’t tried that yet, so just make sure it’s seasoned well!
Loved the recipe! Using uncooked lasagna did not work. Needs more liquid, or cooked lasagna. Yum!
★★★★
Hi Laura, I’m sorry and really not sure why it didn’t cook? I used dry noodles ( see photos) and mine cooked through perfectly. Maybe my sauce was thinner? I will add some notes to the recipe.
Do you think this could work with canned (pureed) pumpkin as a time-saver? Obviously it wouldn’t be quite as good but maybe close?
I think this is fine as long as you season it and thin it out with a little water and olive oil… so it’s more saucy. You could also used a “Harvest Sauce” like the one at Trader Joe’s.
This sounds delicious, and perfect for the squash on my counter!
Did you use regular lasagne noodles, or the “no boil” variety?
I used regular noodles and did not boil them. ?
