This scalloped potatoes recipe makes the ultimate comfort food. Creamy, cheesy, thinly sliced potatoes layered with a mix of cheeses and baked in a rich, creamy white sauce. It’s everyone’s favorite potato side dish.
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 but of course, you can always add some more fun flavors to suit your personal taste!
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 potato casserole features thinly 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.
Kitchen Tools and Equipment Needed
- 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 slicer 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.
How To Make Scalloped Potatoes
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.)
PRO TIP: To reduce the risk of serious injury, please do not use a mandoline by holding the food in your hand! Use the special holder or use cut resistant gloves.
PRO TIP: If you don’t have a mandoline 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 or a fork into the center of one of the potato slices to be sure that the potatoes are not under cooked.
Ingredients Tips and Substitutions
Potatoes – best potatoes to use for scalloped potatoes are russet potatoes. They are starchy, soft, and very tender when baked.
Cheese – I like to use a mix of cheeses like sharp cheddar and Monterrey Jack cheese because one provides stronger flavor, while the other one melts nice and smooth. Any cheese you choose, try to use block cheese and grate it yourself. Pre-shredded cheeses are coated in separators and will affect how smooth the sauce will be.
Cream – for best rich and creamy results, use heavy whipping cream and nothing less! (If you need to keep it lactose free or dairy free, use lactose free half and half and some lactose free sour cream. There are some plant-based whipping cream options if needed, check your grocery stores.)
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 scalloped 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!
How to Make It Ahead of Time
You can easily make scalloped potatoes ahead of time. It’s best to make it ahead unbaked so prepare the whole recipe in the casserole dish, up to the step of baking.
Instead of baking it, wrap it air-tight with plastic wrap or aluminum foil and refrigerate. You can make it up to 2 days ahead of time but I could do it any longer.
To bake it, take the casserole dish out of the oven about 30 minutes before baking. This will give it a chance to warm up a bit. Preheat the oven to the recipe recommended temperature and bake as directed. The bake time might increase by about 5 minutes because the casserole will bake from cool.

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.
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.
Ron says
Would this dish be able to made a day in advance before baking?
Dani M says

Tilly says
This looked irresistible, by adding some cubed ham it became a main dish. I softened the potato slices in the microwave to compensate for our high altitude, and used a can of evaporated milk instead of the cream.
The result was as bubbly, cheesy delicious as the pictures.
lyuba says
Hi Tilly!
I actually have dinner version you might like!

Karen O says
Can I use something to replace the mayo in this recipe? My husband does not eat it and somehow tastes it when it is in a recipe! These potatoes are calling my name and I want to make them.
lyuba says
Hi Karen!
You can use extra sour cream, you can use plain yogurt, and there is also a vegan mayonaise (not sure what it tastes like though 🙂 ). I hope you guys enjoy it!!
