Cheesy Butternut Squash Potatoes au Gratin
Au gratin is a French term for a baked dish that is covered in bread crumbs, cheese, or both. Cheesy Butternut Squash Potatoes au Gratin is a gluten free casserole recipe, with creamy cheddar cheese sauce and Parmesan cheese baked over sliced butternut squash and potatoes.
#SundaySupper has you “covered” this week. Covered in chocolate, covered in frosting, covered dishes. I chose to cover one of my old dishes, turning it into something new; a dish covered in cheese! This is perfect for when you are going to a potluck and need a covered dish. Who knew all of this creamy cheesiness could be packed with veggie goodness? It’s Cheesy Butternut Squash Potatoes au Gratin.

We just returned from a week long Thanksgiving visit to see my aunt and cousins in Kentucky. If you plug her address into our GPS it tells you that it is about a ten hour and fifteen minute drive. That’s without stops. I have two kids – a baby that still eats five or six times a day, and an extremely active three year old that has no interest in any activity that can be done while sitting down, except watching TV. This was clearly going to take longer than ten hours.
So I’m a minivan mom. I hate the thing, but given that any family visit requires a minimum of a two hour drive, and often a several day stay, the birth of the second child pretty much made this a necessity. We bought the van in April, and somehow managed to hide the fact that it is equipped with a television and DVD player. Yeah, until this trip. We got through the first afternoon/evening four hour leg without leg of the journey without revealing this amazing feature, but when we were fifteen minutes into day two and knew we likely wouldn’t be pulling into our hotel until about eight or nine hours later, and he was already kicking the seat and whining and telling us he wanted to go to his cousins’ house NOW, it was time.
We brought a small selection of movies, but you want to guess what evoked this reaction? (this is the still photo – click the link to get the full effect. Trust me!)
Nope, not the latest Pixar movie or a favorite show from Disney Junior or Nick Jr. It was classic Looney Tunes! Pure, uncomplicated, utterly nonsensical, silly and cheesy! Nothing like introducing children of this high tech generation to the wonders of Bugs Bunny, Tweety and Wile E. Coyote!
Now I’ll just have to figure out how to explain that the TV doesn’t work for the five minute drive to preschool to my kid who is just wayyy to observant for his own good. This should be easy.
Speaking of easy and cheesy, these au gratin potatoes…
Umm, yeah, seriously, you want these babies.
I make my recipe for Butternut Squash Macaroni & Cheese often, and we always love it. The butternut squash turns a rich, heavy cheese sauce that typically starts with a flour and butter roux into a gluten free, lighter, but still just as creamy and flavorful dish. So instead of pasta, use potatoes to make a cheddar au gratin.
It took a couple of tries and some recipe tweaks to get it to turn out right, but these cheesy au gratin potatoes are sure to become a staple, just like the macaroni predecessor. It is hearty and comforting, but I can still feel good about letting The Bug have a big helping, confident he is also getting his veggies in. Heck, I was happy to dig into seconds myself. It makes a huge dish, so you can certainly bring this to a potluck, or maybe even add it to your Christmas menu to go alongside that ham. Or just make it for your family, and reheat the leftovers for lunch or dinner later in the week.
