I’ve droned on and on about my love for potatoes in past blogs….especially when talking about my favorite Creamy Parmesan Mashed Potatoes or these irresistible Parmesan Smashed Potatoes. What can I say, potatoes just get me. You know what I mean? So for this holiday season I’ve come up with yet another way to indulge in my favorite starchy friends. How about some Cheesy Potatoes Au Gratin?! Sounds fancy, right? It couldn’t be easier, I promise. You can prep it ahead of time, then bake it about an hour before you’re ready to serve it. Plus you need only a handful of ingredients. Easy, peasy. Let’s do this!
Ingredients
To get the potatoes evenly and thinly sliced I highly recommend a mandoline slicer. The one I have below was less than $10 and works like a charm. The piece on the right is a safety guard so you don’t slice your fingers off. I’m quite injury prone in the kitchen, so this is a life saver…literally.
And you see those little red markings? Those are different levels of thickness for the slices. For this I went with number 2, which is probably about 1/4 inch thick.
How to make it
Preheat oven to 375 degrees Fahrenheit. Spray a 2 ½ quart baking dish with nonstick cooking spray.
In a large glass measuring glass with a spout, add the half and half, kosher salt, and black pepper. Whisk together until well combined.
Layer about 1/3 of the potatoes into bottom of the prepared baking dish. Sprinkle a third each of the Parmesan & shredded Gruyere over the potatoes. Then pour a third of the half and half over the potatoes.
Layer another third of the potatoes, then repeat with a third of the Parmesan, Gruyere, then half and half. Repeat one last time for a third layer, finishing the rest of the ingredients.
Bake in the oven, uncovered, checking to see if the potatoes are fork tender after an hour. Feel free to bake for an additional 10-15 minutes if you want the potatoes more on the mushy side.
Let cool at least 15 minutes before serving to allow the liquid to thicken and absorb into the potatoes.
How gorgeous are these babies?? That burnt cheesy topping is WHERE IT’S AT!!

Looks yummy. I too love everything potatoes as does our son. I look forward to making these over the holidays! Thanks for posting. Wishing you and all your family a very merry and safe holiday season.

Can you tell me the brand of your mandolin slicer?
It’s by OXO! I think I got it at Bed Bath and Beyond :)
Thanks Nikki! I got one but they didn’t have this nice little one. Had to get the next one up. Looks complicated lol. Today will be the test, hopefully no fingers in the potatoes!
Hahaha I hope so too! I really hope you loved this!
Hi ai would like to make this ahead of time . How would you recommend I do that?
That’s a great idea! Just assemble it, cover and refrigerate it overnight. Then bake as usual, perhaps adding an extra 5-10 min :)
