Jalapeno potatoes au gratin? Yes, please!
After not having traveled anywhere for two years, my husband and I have started traveling again. We have a couple of pretty big trips planned but started with a small trip last weekend.

I’ll spare you the details, but what started off pretty rough ended with an amazing breakfast at a local Mexican place. While it was all good, the highlight was what they simply called “jalapeno potatoes.”

We ordered them with the thought we would get some browned crispy skillet potatoes with some jalapeños added in. But then the waitress set down a plate with a perfect square of potatoes topped with green sauce and drizzled with sour cream. Not at all what I had in mind, but I dove in nonetheless.
By the time we were done, we were happy to have had the wrong idea, because the potatoes were delicious. The sauce was tangy and bright, like my favorite enchilada, and the potatoes seemed to me like potatoes au gratin.
Naturally, when I eat something like this in a restaurant, the first thing I do is try to come up with a way to make it myself. Especially if it’s something simple like this.
I started with thinly sliced potatoes (almost paper thin — you’ll definitely need a mandolin for this) and layered them high in a square baking dish. I added some onions and garlic,  then poured milk over them. When making something like this, it’s important to sprinkle salt and pepper between every layer. It may seem like overkill, but it ensures you wind up with something well seasoned throughout.
While the potatoes are baking, I made the sauce. I make a quick blended salsa verde sauce using canned tomatillos because that’s all that was available. It turned out pretty delicious.
I also added cheese to the end, because I genuinely thought there was cheese on the restaurant version, but as my husband pointed out, I was wrong. I stand by the cheese anyway, because, well, cheese. But you do you.
Oh, and these don’t have to be breakfast potatoes. They make a nice side dish alongside tacos, enchiladas, or just by themselves.
