I’m so excited about these easy cheesy au gratin hasselback potatoes! I LOVE these and I know that you will too. These easy potatoes make an amazing holiday side dish that the whole family will love.
When I was a kid, I loved au gratin potatoes. You know, like the kind in the box? I LOVED them.
And now that I cook for part of my living, I obviously no longer make them out of a box. But I wanted to make a holiday recipe to pay homage to one of my childhood favorites.
And guys – it came out so GOOD. This is one of those ‘grab a fork and eat it out of the pan’ recipes.
Note: This recipe requires a mandoline. Please, please, please: wear a protective kitchen glove when using a mandoline. They are sharp people, and you all need all of your fingers.
