The Best Scalloped Potatoes
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 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 is the best potato casserole recipe 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.
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.)
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.

I love this recipe and always take it to others when taking a meal. Tip to lessen cooking time.: I cook just the potatoes in the microwave to partially cook before putting the casserole together. 😋
Glad you like it, Brenda!
One of my families favorites. Creamy, cheesy, Delicious !
So glad everyone likes it, Donna!
Can these be frozen? I am assuming you should bake first?
I would not freeze this because heavy cream doesn’t defrost well and the texture won’t be the same.
I apologize. I’m soooooo happy to have found the quantities!!! Can’t wait to make it!!!!!
I hope you enjoy it, Virginia!
It would have been nice to know the quantities of all ingredients in this recipe instead of making us guess!!! Very incomplete recipe!!!!
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.
je regarde beaucoup de vos recettes et je les aime beaucoup, merci de nous les partager
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.
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.
Scalloped potatoes do not have cheese in them. Your recipe should be named au gratin potatoes.
