Jalapeño Au Gratin Potatoes

We recently took a trip to Florida with a group of friends and ate at a fantastic steak house. I love a good steak, but for me it’s really all about the side dishes. One of the perks of going out with a large group is getting to try a little bit of everything. Hands down one of the best dishes of the night were the Jalapeño Au Gratin potatoes they served! I’ve been on a mission to recreate it at home and I think I finally got it.

I have to admit, I was a bit skeptical to try these at first since I’m not huge of spicy food. These have such a nice creamy cheesy texture with just a hint of heat. Of course if you love spicy food you can easily kick this up by adding more jalapeños!

These Jalapeño Au Gratin Potatoes are obviously a great side to steak as previously mentioned, but they would also pair nicely with a honey ham. They also make a fun addition to brunch and they are perfect for your next holiday gathering.
