Roasted Butternut & Sweet Potato Lasagna

Oh dear. This is my third post about butternut squash in what, 2 weeks? I think I'm in love. It just keeps getting better. First, this incredible soup. Then, it turned traditional pizza on its head. has invaded the comfortable world of lasagna.

And I love it even more for the intrusion. Not long ago, I wouldn't have dared put a vegetable in my lasagna (besides tomato sauce), but this delectable yellow gourd has turned a lot of my preconceived notions about vegetables and meatless dinner upside down. Even my husband has been blown away by how delicious and filling a meatless entree can be. I'm begging you as a friend to please, please put all your inhibitions aside and make this lasagna. Okay. Now that I've reduced myself to pleading, let's proceed to the "how" of this culinary adventure.
Begin by peeling and dicing a butternut squash and one or two sweet potatoes or yams. Side note: this is not an expensive dish. I purchased a medium sized squash for only a little over $3 and it played a starring role in 3 dinners, plus leftovers! You want to end up with 3 1/2 to 4 cups altogether. Spread them on a baking sheet and drizzle with a bit of olive oil, sprinkle with nutmeg, salt and pepper; toss to coat.

 Roast in the oven until they are slightly crispy and soft enough to poke a fork through.

While the squash is roasting, you can get to work on the cheese filling. The first step in the filling is to cook onions (or shallots) and garlic in brown butter. I didn't have any shallots, so I substituted some sweet onion, which seemed to work fine.

If you haven't browned butter before, you'll find a tutorial here.
The original recipe also called for mascarpone cheese, which sounds amazing, but which I could not find, even at our local Safeway. So, if you can't find it in your area either, you'll find a substitute recipe below. It was delicious. Combine the browned butter, onions and garlic with the mascarpone (or masquerading mascarpone- say that 10 times fast!) and add Parmesan cheese. Set aside.
When the squash and potatoes are done, transfer them to a bowl and mash until smooth with a pastry blender. I whipped them up even creamier with an electric mixer.

Now, you're finally ready to layer!

Some of the comments on the blog I found this recipe on complained that the bottom noodles were crispy, so it was recommended that you put a bit of the squash on the bottom of the pan first- which I did (and it turned out perfect).

Cover that with lasagna noodles. I discovered oven-ready lasagna noodles for the first time on our last shopping trip and had to try them. I must say, I am impressed. They turned out perfectly, no pre-cooking required! Squash mixture goes on top of that, followed by the cheese filling.

Sprinkle a bit more cheese on that, then repeat! This is probably the easiest part of the whole ordeal. :)

Pop it in the oven and wait for delicious aromas to start pouring forth. They will.
Usually you can be fairly alerted to the presence of a tasty meal by the smell. And this dish is no exception whatsoever. I knew I had hit on something good when my husband kept coming in the kitchen, sniffing and saying things like, "Boy, that smells amazing!" It did. We could hardly wait for the pan to come out of the oven and cool long enough to slice. Hubby, hovering, says, "Can we eat it yet?" Good things come to those who wait.
There are so many flavors packed into this hearty dish I don't even know where to start. Which is why, I beg you, please make it for yourself! One thing we remarked to each other as we were eating (pulling our mouths away from our forks long enough to speak was pretty remarkable, come to think of it) was that you could distinguish each separate flavor as you were eating. Squash, smooth and rich. Then tangy and creamy cheese. Nutmeg, aromatic and spicy. Fragrant and pungent garlic. A hint of mellow sweet potato. It was all there. Together, but somehow...separate. Each bite was packed with alternately bursting and mellowing flavors. What an experience! In the words of the blogger who drew me in: "It's like eating a giant plate of autumn." I couldn't have said it better myself.

  1. Yum! Sounds delicious! Wonder if I could convince my crew to like it? They are not huge squash fans...but I LOVE squash!
    What section of the grocery store are you looking for marscapone in? I always find it near the deli with the specialty cheeses. ( :
    Have you ever tried making homemade pasta? I make it often; doubling up and freezing the extra. You can roll a basic dough into lasagne sheets as well. I am planning on trying it soon; I usually just make noodles for chicken noodle soup. Let me know if you want my recipe. ( :
