I’ve said a million times now that potatoes of any kind are not my drug of choice – I’ll usually choose brussels sprouts, but this Sweet Potato Gratin is just so cheesy and creamy and, yes, lighter, at the same time.

This gratin though, it has to sit around for a bit before you serve it. If served right away, while it’s still super hot, the creamy sauce won’t have enough time to thicken a bit and hold up. Which, if you ask me, it’s a great thing! That means you can make this side dish first, and free up the oven for the one that should be served hot.

Here’s what’s gonna go down when you make this. First, we’re going to slice the potatoes. Also, because we’re going for a lighter version of this traditional side dish, you are going to reach for a can of evaporated milk and push away the heavy whipping cream. There’s plenty of cheese in here to make up for some of those creamy calories.

The sauce will also include a handful of grated parmesan cheese, as well as swiss cheese or gruyere cheese – whichever one you have sitting around. A bit of thyme will also go in here, and some ground ginger and nutmeg.

All of that will be poured over our beautifully sliced sweet potatoes and go into the hot oven for about 50-some minutes.

Let it cool, then top it off with freshly grated parm, dried parsley, grab a fork and do your thang. 🍴

ENJOY!

  1. This sounds like a great holiday side for those who enjoy sweet potatoes. I love potatoes au gratin, although I do wish I could slice my potatoes a tiny bit thinner when I make it.
