With brown butter and creamy mascarpone and crispy sage and caramelized shallots and a bunch of other delicious stuff that was waaaay too long to fit into the title.

I’m in dirty lust.

Which is huge. Because you may remember that I don’t even like lasagna. Oh cheese and quackers! Big news: I now love it. I don’t just love it. I flippin’ love it.

Sidebar: does sage freak anyone else the heck out? It’s just so… furry. It is one of my favorite herbs – I love everything about it from it’s taste to it’s scent, but I can barely get past it’s touch. And it’s not furry like a peach. It’s furry like some sort of… creeper.

That’s why I like to make it crispy. Well, that… and because two weeks ago I ate pumpkin ravioli with crisped sage over top and I actually thought that I had died. Like, that I was dead. Literally. Nothing on Earth should be allowed to taste that good.

Here’s one thing I will not be winning an award for anytime soon… cutting squares of lasagna. I think you’re supposed to let it “set” or something? Ha! Like I’d have the patience for that. I nearly consumed the pan with a spoon fresh from the oven. Taste buds be damned.

I know that this mess of cheesy squash doesn’t look like much, but I gotta tell you that it’s probably the most visually underrated dish I have ever made. I didn’t expect it to taste half as delicious as it did… and I was completely blown away. There is so much flavor packed into each little square that it’s like eating a giant plate of autumn. Plus, all of that squash has to count for a few days worth of vegetables. I love when I accidentally on purpose eat something delicious.  

Roasted Butternut and Sweet Potato Whole Wheat Lasagna I howsweeteats.com

Roasted Butternut and Sweet Potato Whole Wheat Lasagna

makes one 8×8 dish

9-12 whole wheat lasagna noodle sheets (preferably no-boil)

1/2 medium butternut squash, peeled and cubed (about 2 cups cubed)

2 medium sweet potatoes, peeled and cubed (about 1 1/2 cups cubed)

12 ounces mascarpone cheese, at room temperature

3 tablespoons unsalted butter

1 shallot, thinly sliced

3 cloves of garlic, minced or pressed

1 1/2 cups freshly grated parmesan cheese

1/2 cup freshly grated mozzarella cheese

1 teaspoon salt

1 teaspoon pepper

1/4 teaspoon nutmeg

a bunch of sage leaves

olive oil for drizzling

Preheat oven to 350 degrees F.

For squash & potatoes: Lay cubed squash and potatoes on a baking sheet, and drizzle with a bit of olive oil (only about 1-2 teaspoons). Use your hands to coat the squash and potatoes with olive oil, then sprinkle with nutmeg and 1/2 teaspoon each of salt and pepper. Roast for 50 minutes, tossing every 15 minutes or so. Remove from oven and let cool.

Once cool, mash with a potato masher or fork. After mashing mine, I actually used a hand mixer with beaters to “whip” them a bit more, but that isn’t necessary. The consistency is up to you. Just make sure it is spreadable.

For mascarpone filling: Heat a skillet over medium heat and add butter. Add in shallots and garlic, and whisk every 30 seconds or so for 2-3 minutes. The butter should brown and the shallots and garlic should be fragrant. You don’t want the butter to burn –  if it seems to hot, reduce the heat. If it does burn, start over (sorry – totally worth it though!). Remove from heat and let cool for 10 minutes.

In a bowl, combine mascarpone, 3/4 cup parmesan cheese, remaining salt and pepper, and the shallots, butter and garlic. Mix until somewhat smooth and spreadable.

Layer lasagna: Spray an 8×8 pan with non-stick spray, then lay 2-3 (depending on size/brand) noodles down. Spread half of the squash mixture evenly over top, then spread/crumble half of the mascarpone on top of that. Sprinkle half of the mozzarella and remaining parmesan on next, then repeat with one more set of noodles, squash, mascarpone, and cheese.

Top the dish over with a bunch of sage leaves that will crisp up in the oven. Bake for 45 minutes, or until cheese on top is golden and bubbly. This dish will serve 2-4 as an entree, and 4-6 as a side dish.

Promise me you’ll make this for dinner. Promise!!

    mmmm you don’t have to beg me to make this. I will definitely be making this very, very soon. squash, sweet potatoes and mascarpone are three of my favorites!! I am actually having mascarpone and pumpkin right now in the form of oatmeal!

    my honest answer — October 18, 2011 @ 7:05 am

    Ah it looks so good, but I hate peeling and chopping butternut squash. Could I just halve it, roast it for a bit longer, and scoop the flesh out with a spoon? Pretty please?

    My lasagne (that’s the UK way of spelling it) never comes out in neat squares either.

    Don’t worry about it – it still tastes good whether it is neat or a little messed up!

    Jessica — October 18, 2011 @ 7:07 am

    I just printed out the recipe to make tonight! That looks like one of the most delicious things I have ever seen- and I LOVE lasagna so it’s even better :)

    Lys — October 18, 2011 @ 7:13 am

    Oh my goodness, butternut AND sweet potato, with pasta!?! Amazing. I have two butternut squash from past two weeks of CSA distributions and have been wondering what the heck to do with them.
    How sweet is this dish? I know, I know, does it matter? Hello, butternut and sweet potato are supposed to be awesomely sweet. However, Roo….he hates squash….and sweet potatoes. I’ve been trying to convince him otherwise but with no such luck (and his common complaint being that it’s too sweet for him in something that he thinks is supposed to be a savory dish).


    • Jessica — October 18th, 2011 @ 10:27 am

      I was afraid that it would be really sweet – but it isn’t. I think it helped that I didn’t add anything like cinnamon or pumpkin pie spice to the squash mixture. The garlic, shallots and brown butter give it a ton of savory flavor.

    I just want to tell you I am obsessed with your blog! All of your recipes always have me drooling! This looks incredible. I so agree with you about the sage, the furry texture is so weird. My hubby eats the skin off peaches and that totally grosses me out too! Can’t wait to make thia dish.


    • Jessica — October 18th, 2011 @ 10:26 am

      Thank you so much Natalie!

    Bookmarking this recipe! I am making this, to bad my husband doesn’t like sweet potatoes or butternut squash, but I do! I guess I’ll enjoy this all myself and freeze the rest!! Yah!! I look forward to this meal!!

    Elysha — October 18, 2011 @ 7:24 am

    Now I’m ticked at myself for using my butternut squash yesterday to make soup. And it was good soup, but come on! Lasagna?! Guess I’ll be taking a trip to my cousin-in-law’s farm stand sooner than I thought…

    I looooove this! Sage does freak me out. So much in fact that I’ve never cooked with the fresh stuff. I’ll trust you on this one though, and see how it goes. It looks too good not to!


  21. #
    Erica — October 18, 2011 @ 7:45 am

    Oh my gosh! How amazinggggggggggg. Sage is a rocking spice. The fur- totally freaky, but totally worth it for the taste ;). And BN squash makes so many dishes better

    gahhh these right here are all my favorite flavors combined. I’ve made several autumny dishes using sage, cream, and pumpkin or squash but this seriously just trumped all of them (obviously). I’m thinking of trying to make a GF adaption of this perhaps. Looks amazinggggg

    Rachel @ Not Rachael Ray — October 18, 2011 @ 8:28 am

    Looks amazing. Love the 1st oozing squash picture. :) Where do you find no-boil whole wheat lasagna noodles? Am I missing something? TJs? I’ll have to keep my eyes open next time I’m at the store!


    • Jessica — October 18th, 2011 @ 10:24 am

      Mine are the Delallos brand brand, but I actually have the Delallos store like 5 minutes from my house. I know they supply pasta to stores all over the US but not sure about the noodles! I’ve never seen them at TJs… maybe more likely at Whole Foods?


      • Rachel @ Not Rachael Ray — October 18th, 2011 @ 10:33 am

        I’ll let you know where I find them!

    Barry — October 18, 2011 @ 8:38 am

    Haha. I’m also the type of person who just can’t wait for it to set before cutting it into squares. I just plop the whole pan on my plate and have it that way. And it’s goooooood.

    Jennalee @ Icing on the Cake — October 18, 2011 @ 9:18 am

    Wow, this looks delicious! I agree with you, sage, just like okra, is so furry! It took me forever to get past the furriness of okra, I refused to eat it until I cooked it a way that got rid of the furriness, and made it taste great, too! Anyway, this lasagna looks delicious, I’ll have to make it sometime soon!


    • Jessica — October 18th, 2011 @ 10:22 am

      I’ve never tried okra. Scurrred.


  46. #
    Jessica @ Stylish Stealthy and Healthy — October 18, 2011 @ 9:23 am

    I think you could let lasagna “set” for like 2 hours and it would still be a hot mess. Except it wouldn’t be hot because you let it set for so long… you get what I’m saying. I say the cheesier and gooey-er the better :)

    Lisa @ Life in Green — October 18, 2011 @ 9:36 am

    I love the feel of sage…crap does that make me a creeper? The smell and taste is even better tho.
