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.

Mandoline Safety

First, you'll use a mandoline to slice the potatoes veeeeery thin. Please, please, please: wear a protective kitchen glove when using a mandoline. They are sharp people, and you all need all of your fingers for the holidays.

Here are some products that you should use for this recipe, both found on Amazon:

Mandolin - This mandoline is very similar to the one I have. You'll want to invest in a good mandoline so they last forever!
Kitchen Glove - PLEASE use one of these whenever you use the mandoline. Your fingers will thank me. Check out this one for a good affordable option.

Ok, now that we've got our mandoline and glove, you'll want to slice the potatoes reeeeeeal thin. I love arranging them in a rose in the center like the picture below, but you do you!

You can have then laying down flat or more upright, it's all based on your preference.

The Recipe: Easy Cheesy Au Gratin Hasselback Potatoes

Now that we've got our potatoes sliced, let's get cooking!

You'll make a super delicious buttery cheesy sauce for your potatoes. Don't skimp on the whole milk - this recipe needs the fat!

Pour the sauce all over the potatoes, top with more cheese, and bake, and then BAM, you've got a delicious cheese potato dish that is perfect for the holidays.

I personally love sage, and I think sage is delicious with this recipe. Rosemary and thyme are great too!
