Recently, I read a recipe for a lightened-up mac and cheese, where half of the pasta had been replaced by cauliflower. I was intrigued. I'm not eating a ton of pasta these days, so I figured I'd give it a go using 100% cauliflower. And why not try it with my trusty brown butter-pumpkin combo?
My Brown-Butter Pumpkin Mac and Cheese is probably my most-searched recipe. I invented it a whopping five years ago, when I was looking for a way to lighten up some mac and cheese (read: eat mac and cheese more often), and so I added some canned purreed pumpkin to a cheese sauce. The resulting mac was creamy and cheesy, but the addition of pumpkin meant I needed significantly less cheese to make enough sauce to coat my pasta. It also added some much-appreciated fiber, along with its rich, nutty flavor, which gorgeously complemented the cheese.

I started by roasting a whole cauliflower with half an onion.
Next, I browned some unsalted butter, just until it got nutty and really good-smelling.
I whisked in some pumpkin, milk, and sharp cheddar cheese, plus salt, pepper, and a touch of nutmeg, which works nicely with cheese and pumpkin, to make the sauce.
I stirred in the roasted cauliflower, right into the pot (all hail the multi-purpose Dutch oven!).
And topped the whole thing with a little more cheese.
Into the oven it went, and the result was astonishing.
I mean. Oof. Just, wow.
I'm not going to lie to you and tell you it tasted like mac and cheese, mostly because this dish is delicious and worth making in its own right, mac and cheese-likeness aside. That said, if you're hankering for mac and cheese but, like me, you're keeping half-an-eye on your carb intake, this cheesy baked casserole will most definitely conquer that craving.
