This scalloped potatoes recipe makes the ultimate comfort food. Make this recipe for creamy, cheesy, thinly sliced potatoes, baked in rich cream sauce. So creamy, so cheesy, everyone’s favorite side dish for holiday dinner or any other night.
SCALLOPED POTATOES
This is my family’s favorite side dish of all time. They can eat it for breakfast, lunch, and dinner. If I let them, they’d eat it all day, every day. Honestly, this recipe makes the best potato casserole you will ever try!
These scalloped potatoes are the epitome of comfort food and taste so good, it’s worth every calorie. It’s not just scalloped potatoes or potatoes au gratin, it’s both put together since it’s made with cream and cheese. I save this special side dish for special occasions and holidays.
Whether you make this recipe for a holiday gathering, a potluck, or a simple family dinner, it will most likely be everyone’s favorite side dish. This baked casserole features thin slices of potato in a rich cream sauce with plenty of cheese. It’s incredibly rich and indulgent, but seriously delicious!
No disrespect to the other delicious potato recipes out there, because of course, my Loaded Cheesy Potato Casserole is also pure comfort food.
Difference between au gratin and scalloped potatoes
The primary difference between au gratin and scalloped potatoes is the use of cheese.
Both methods involve layering potatoes into a dish for baking. But, potatoes au gratin includes layers of cheese, while recipes for scallop potatoes do not typically include cheese. Rather than cheese, the highlight of scalloped potatoes is the creamy sauce!
What makes this particular recipe so special is that we use a combination of those two methods. Our creamy scalloped potatoes recipe uses cream sauce AND cheese!
KITCHEN TOOLS AND EQUIPMENT
Baking dish: I use a 13×9-inch casserole dish, or you could also use a 2-quart (or larger) oven-safe baking dish.
Kitchen knife: A chef’s knife or kitchen utility knife (santoku) will give you effortless slicing and dicing ability. Just make sure the knife is sharp, you never want to work with a dull knife.
Mandoline slicer: If you’ve ever seen food cut into paper thin slices, chances are good that a mandoline was used to cut them. Using one isn’t required, but they sure are nice to have because it will make slicing pounds of potatoes effortless. Make sure to use the holder that comes with it or use cut-resistant gloves.
SCALLOPED POTATOES RECIPE INSTRUCTIONS
Prep: Preheat your oven to 350°F and grease a baking dish with a little bit of vegetable oil or non-stick cooking spray.
Prepare the cream sauce.
Make the cream mixture by whisking together sour cream, mayo, heavy cream, garlic powder, onion powder, salt, and pepper and set it aside.
Slice the potatoes.
You’ll need to slice them very thinly. If you use a mandoline slicer, be very careful, please watch your fingers, and always use a pronged food holder or cut resistant gloves. (The food holder is a plastic piece with prongs on the bottom to hold large pieces of food as they go through the slicer. A good quality mandoline should come with a food holder in the box.)
NOTE: To reduce the risk of serious injury, please do not use a mandoline by holding the food in your hand! If you don’t have a slicer available, use a sharp knife to cut the potatoes into thin slices. Slice them as close as possible to equal thickness.
Layer the casserole.
Spread a thin layer of cream sauce in the bottom of the baking pan.
Start by layering a third of the potatoes in one even layer.
Then, sprinkle 1/3 of the shredded cheese over the potatoes and spoon 1/3 of the sauce over the cheese and potatoes.
Repeat these steps, layering potatoes, cheese and sauce two more times.
Finally spread some more cheese over the top.
Bake the scalloped potatoes.
Cover the dish with foil and bake for 1 hour. (TIP: spray the side of the foil that will be touching the potatoes with some cooking spray to prevent sticking.)
Then, remove the foil and bake for another 15-20 minutes. Doing this allows the cheese to melt and become golden brown.
Test for doneness: Insert a butter knife in the center of one of the potato slices to be sure that the potatoes are not under cooked.

Dani M says
Amazing!! So good! I’ve made scallop potatoes before and always have trouble baking them through. I boiled my sliced potatoes for a few minutes before preparing the dish. Thank you for sharing!! I’ll be making this again!
LyubaB says
Dani, I’m so glad you liked them! 🙂
Ron says
Would this dish be able to made a day in advance before baking?
LyubaB says
Hi, Ron! Yes, you can make this the night before! Just make sure you are using a casserole dish that can go from being cold to hot without cracking, if not I would let it sit out 30 min or so before putting it in the oven.
Lynn says
This looks delicious. Can you make and bake the day before and just heatup the next day? I saw in the previous post you can make ahead but does that mean bake too or just put together.
LyubaB says
Hi, Lynn! Either way you would work. You can make and bake the next day, or make and bake same day then heat it up later, whichever you prefer.
Donna says
Scalloped potatoes do not have cheese in them. Your recipe should be named au gratin potatoes.
Daniel Ban says
This recipe is delicious the only think was for me it took more then two hours for the potatoes to be done I don’t know wat I did wrong.
LyubaB says
Hi Daniel,
Thank you, I am so glad you liked the recipe! There are a couple of things I can think of that may have resulted in a longer cook time, like if you sliced them by hand they could be a little thicker and take longer to cook or you can check if your oven is heating correctly with a separate oven thermometer.

votre traduction qui est faite en français est erronée, il n’y a pas de pétoncle dans cette recette…
il ne faut pas traduire avec un traducteur offert sur internet mais bien par une personne comprenant bien les deux langues
ce serait bien de nous donner les vrais ingrédients et le mode de préparation adéquats.
