These Easy Potatoes au Gratin (otherwise known as Dauphinoise) are a French classic. But don’t let that scare you. They are so easy to make and comforting with its layers of sliced potatoes, cream, and cheese!

Au gratin potatoes are a family favorite and it pairs well with so many meat dishes. It can be for both casual family dining or serve it to guests. A few other potato dishes we love are Slow Cooker Mashed Potatoes, Scalloped Potatoes, or Roasted Parmesan Potatoes.

So I’m sure a few of you are wondering what’s the difference between scalloped potatoes and au gratin because aren’t they the same thing.

Well, no they aren’t. And here’s why:

True scalloped potatoes DO NOT have any cheese and au gratin potatoes have cheese and even a breadcrumb topping sometimes.

So there you go….now you know the difference!

What are the best potatoes for au gratin?

There seems to be a debate about what potato is best. Some say only use russet or a starchy potato while others swear by the waxy sort.

Personally I prefer to use russets because they are the cheapest and help create a creamy sauce. I don’t make a cheese sauce ahead of time but rely on the starchiness of the russets to help create a luxurious sauce.

You can try substituting in a Yukon gold potato if you prefer.

Tips and suggestions:

  • Cheese: you can use Gruyère, cheddar, or Parmesan. You can even use a combo if you like. Just be sure to use one of the three to add flavor to your dish. I also added sliced provolone for extra cheesy goodness!
  • Slice your potatoes as uniformly as possible so they cook evenly. You can use a mandoline to take the guesswork out if you prefer. If you don’t have one don’t let that stop you from making these creamy cheesy potatoes! Just cut a thin slice along the length of the potato then place the cut side down on the cutting board so it doesn’t wobble everywhere.
  • I kept this pretty basic as in I didn’t add in any herbs or onion. I did use garlic powder though just to give it a little something. Feel free to leave it out if you prefer. Add 1-2 teaspoons of fresh thyme if you would like to change it up.
  • Please don’t use anything other than cream for this recipe. Yes, I know it sounds indulgent but that’s the way it’s supposed to be…..it’s not called comfort food for nothing, lol!

    In our house, we call this recipe THE Potatoes Au Gratin! You’ll never need another recipe. These are delicious and so easy!

  2. Hi, I plan on making this with my ham, but the temperature for the ham is 275 for about 2 hours and this calls for 425 for 50 min, then 10 after uncovering. Do you have any idea of how to cook both in the same oven, what temperature, how long. I’m not a very experienced cook. 🙁 If I decrease the temperature, do you know how much longer I should cook it?
    Thank you.

    • I don’t know what this cook recommends but I’m in the same boat. I’ve decided to cook the potatoes first. Instead of removing the foil and replacing them, put them foil covered to the side and put my ham in the oven, lowering the temperature. My ham only needs 1.6 hours. Then return the potatoes to finish off while the ham is glazed. Good Luck and happy holidays!

    • I don’t recommend cooking the potatoes with the ham at that low of a temp because the potatoes will not be done. A couple of things you can do are: make the potatoes the day before and reheat in the oven (remove from the refrigerator 2 hours before reheating) covered then broil briefly to crisp the top if you would like. Or you can heat your ham in a slow cooker freeing up your oven for other dishes. If you want to use the slow cooker you can follow my recipe for this Honey Mustard Ham and leave off the honey mustard if you prefer. Please let me know if you have any other questions and Merry Christmas!

    • I haven’t tried this recipe in the crockpot so I can’t say for sure. But if you do try it cook it on low starting with 4 hours and see if the potatoes are done.

    I plan on making this dish with my ham this weekend. Do you have to make it ahead of time and refrigerate overnight, or is that just a note in the event someone wants to make it ahead of time?

    • No you don’t have to make it ahead of time. It’s just an option for those who want it. Thanks and I hope you enjoy!
