Potatoes au gratin are nothing more than scalloped potatoes with a cheesy cream sauce. They're just so darn easy!
🧾 Ingredients
🔪 Instructions
- Make the first layer of using ⅓ of the potatoes. Be sure to lay your them in an even layer. Then top with onions, and shredded cheese.
- Repeat building the layers until you have used all of the remaining potatoes.
- Make the bechamel sauce and then pour over the layers.
- Top the dish with bread crumbs and remaining cheese and then bake.
🥫 Storage
Store leftovers in an airtight container for up to three days in the fridge. Or cover your casserole dish tightly in plastic wrap or foil for easy storage.
I don't recommend freezing this casserole as the potatoes will change texture when they are thawed.
📖 Variations
- Turn this recipe into Jalapeno Scalloped Potatoes by adding sliced jalapenos to the layers when you are assembling this dish.

- Add cooked bacon and diced chives for a loaded twist on this casserole.

💭 Tips
Expert Tip: When making a cream sauce always cook the flour for at least a minute or two to get the raw, starchy taste out.
- Be sure to preheat your oven before putting this dish in the oven. This will help ensure that your potatoes bake evenly.
- Make sure you slice the potatoes thinly and evenly. A mandolin or food processor can help you get those even slices.
- If you want a golden brown crust on your potatoes, put them under the broiler for a few minutes after they are done baking. Just be sure to keep an eye on them so they don't burn!
- Evaporated milk is what makes this dish extra creamy, using milk will take away some of that creaminess.
- If you like your sauce a little on the thinner side, add a small amount of chicken broth to your bechamel sauce.
- Add in a tablespoon of thyme for a flavorful twist.
👩🍳 FAQs
I prefer sharp cheddar cheese, but a Colby jack or cheddar Colby mix would work well also.
Potatoes au gratin are made with a cheesy sauce and then topped with breadcrumbs whereas scalloped potatoes have a sauce that is mixed in with the potatoes.
I like to use Yukon Gold potatoes but russet potatoes and red potatoes will also work in this recipe.

📞 The last word
My mom made the absolute BEST scalloped potatoes but she never added cheese. The first time I put a forkful of potatoes au gratin in my mouth I was hooked.
They're so easy to make - and you can make them ahead of time. Be sure to add this old fashioned side dish to your meal rotation!
Oh...put a baking sheet under your casserole dish because these will spill over a little - they're 'sposed to. It's part of the charm. Those crusty, blackened bits add flavor!
Serve these the next time you have ham or roast chicken. I promise your family will worship you. Well, maybe worship is a bit too extreme. Let's just say they will like them... a lot.

I love potatoes just like this Marye. Sharp cheddar is the best, and I know Cabot extra sharp would be perfect for this yummy recipe.
Jessica @ Stuck On Sweet says
These look delicious! I love potatoes, too...especially with all that cheese!
Dawna says
I tried to make the sauce, it looked fabulous but once cooked, it looked like it curdled. The milk was good, I don't know what I did wrong.
Marye Audet says
It sounds like you didn't get the sauce thickened or you didn't whisk it continually until smooth. The flour can lump up if it is not whisked as it is cooking
