Yep, you read it right. This mac n cheese has a crumbly, sweet, cookie topping—and it makes the dish (it's so good). But before you scroll straight to the recipe, read our notes. Because whoa, there is one major mistake in there.
We got this recipe from Martha Stewart—a consistently foolproof source—but it is originally by chef Todd English. We're guessing that this might be a recipe Martha and Todd made on her show that wasn't fully tested by her test kitchens before it hit the web? That's the only explanation we have for why...
...it makes at least twice as much as it says.
Seriously. Get your mixing bowls and casserole dishes ready, people. We were prepared after reading two pounds of macaroni and four squashes. But there are a few other issues, too.
Here's what you need to know:
• The recipe calls for two butternut squashes and two acorn squashes, but it specifies each should be about 1 1/2 pounds. Our butternut squash (a very average one) was 3 pounds by itself. You don't need two.
• While the pasta and squash puree will easily fill two 9x13 casserole dishes, the ricotta (which you dollop on top) and the breadcrumb-cookie topping is only enough for one. You'll need more ricotta and more topping for the other dish.
• This is not a gooey, traditional mac n cheese. The cheeses are parmesan, mascarpone, and ricotta—no bechamel, no super melty cheddar or mozzarella. It's a lighter, drier macaroni. We liked it as an alternative (it felt healthier!), but it's something to keep in mind.
We'd never had crushed amaretti cookies on a savory dish, but they're perfect here. They have a toasty flavor that brings out the sweetness of the squash and makes every bite feel indulgent.

I'm honestly not that surprised. I haven't had much luck at all with recipes on Martha's website. I don't trust them anymore and go there for ideas more than recipes.
I've never had much luck with Martha's recipes either.
Martha's recipes - or at least, those that get her imprimatur - often have one thing that seems "out of scale" for the dish. Sometimes it's too much stock or liquid (so I just reduce the amount...) or, most often in my experience, WAY too much oil. This doesn't extend to her baking recipes, though; those are (in my experience) completely right on.
But yeah, one who reads MS-empire recipes all the way through for "match," and then adjusts as it seems is required, is rewarded.
I agree. I've had some really bad luck with Martha recipes, including one pie/tart thing that had a huge amount of butter. It seemed like way too much, but I went with the directions anyway. After about 15 minutes in the oven, melted butter was pouring out of the bottom of the springform pan. What a mess. A big, smoky mess.
What's going on with Martha? I will NEVER forget the close to 100 sugar cookies I made for Valentine's Day. They were so bad the kids wouldn't even eat them. Hard as a rock, awful taste. You would have thought that I learned my lesson. But NO...I tried a chocolate cupcake recipe that my son and husband threw away. And don't even get me started on a cake that was probably the most expensive kitchen disaster I've ever had -- all those specialty ingredients, four layers of just plain horrible. I'm usually considered a good cook, but her recipes have made me look terrible. At this point, I might use her for inspiration, but actual recipes, no thanks.
Interesting. I have a butternut squash lasagna recipe that calls for a few amaretti cookies in the squash puree, and while I hadn't heard of this practice before making the recipe, it is really tasty.
Todd English himself did this recipe on The Talk..you can watch a video of it there or you can find a written version at http://thestir.cafemom.com/food_party/128309/butternut_mac_n_cheese
It calls for only ONE pound of squash and has no mascarpone cheese at all in it....
