An Easy Classic

Of all the potato side dishes, from oven-roasted potatoes to creamy buttery mashed potatoes, nothing says comfort food like this scalloped potatoes recipe.

So exactly what are Scalloped Potatoes? Said to have originated in England, the word ‘scallop’ refers to how the potato is sliced. Thin and uniformly cut potatoes are layered in a casserole dish, covered with a seasoned onion cream sauce, and baked. The result is this savory scalloped potato recipe!

Ingredients

  • Potatoes – Yukon gold potatoes (or red potatoes) have tender skin and don’t require peeling (they hold their shape well). Russet potatoes or Idaho potatoes will work; however, they tend to break apart (but still taste good).
  • Onions – Diced onion is a classic ingredient and adds a lot of flavor to this recipe.
  • Cream Sauce – The cream sauce for these potatoes is quick to make with flour, butter, milk, and broth.
  • Seasonings – Simple seasonings in this recipe include salt, pepper, onion, and garlic.

Variations

  • Cheese – If you’d like to add cheese, remove the sauce from the heat and stir in a handful or two of shredded cheese. It will melt from the heat of the sauce.
  • Herbs – Add ½ teaspoon of dried thyme or crushed rosemary, or 1 tablespoon fresh parsley.

How to Make Scalloped Potatoes

Making scalloped potatoes from scratch takes time but is easy. While traditional scalloped potatoes do not have cheese, we sometimes add a little bit!

  1. Thinly slice potatoes & onions.
  2. Make homemade sauce (recipe below)
  3. Layer potatoes, onions, and sauce. Cover and bake.
  4. Remove the foil and bake a bit more; this step creates a delicious golden brown topping on the scalloped potatoes.

IMPORTANT Cool 20 minutes before serving to allow the sauce to thicken.

Tips for Perfect Scalloped Potatoes

  • Slice the potatoes evenly to ensure the scalloped potatoes cook evenly
  • Use a mandoline to make this job extra quick (a $25 mandoline like this one does a great job and will save you lots of time)
  • A roux is the foundation for a creamy sauce. A roux means to cook fat (in this case butter) and flour and add liquid to make a sauce!
  • If you decide to add cheese to the sauce (which will actually make these into Potatoes Au Gratin) remove the sauce from the stove and stir in 1 1/2 to 2 cups of cheese (cheddar/gruyere are great choices).
  • Season the potatoes with salt and pepper between layers.
  • Cover with foil while it bakes; this allows it to steam, and the potatoes will cook a bit faster.

What is the Difference Between Scalloped and Au Gratin Potatoes?

Potatoes au Gratin are also called cheesy potatoes because the white sauce is actually a cheese sauce (and they often have cheese sprinkled between the layers and/or breadcrumb topping).

This scalloped potato recipe can (of course) be topped with cheese or have cheese added in but sometimes I love the simplicity in this recipe without cheese. The sweetness of the onions and milk is the perfect addition to these sliced potatoes!

Can You Freeze Scalloped Potatoes?

These potatoes will keep in the fridge for about 4 days and reheat well in the microwave, oven or in a frying pan! If you want to freeze them longer, yes, scalloped potatoes can be frozen!

Almost any casserole dish can be frozen perfectly with a little know-how. If making a freezer meal, the best way to freeze scalloped potatoes is to not fully cook them all way, but leave them a little undercooked.  Then, once they are cooled in the fridge, portion them out the way you want to and wrap carefully before putting in the freezer. To reheat, simply thaw and finish the cooking until the potatoes are tender again!

While that’s a great option, most often we want to freeze leftovers. In this case, these scalloped potatoes freeze well, although I do find they sometimes break apart a bit when reheated but they still taste great!

  1. Hi Holly, your recipe is so very similar to what I have been making for 40 years. I absolutely love that you know the difference between Scalloped Potatoes and Potatoes au Gratin because the internet does not. Your recipe, like mine, are one of the few without cheese.

  2. Earlier on in the description step three says “3. Layer potatoes, onions and sauce. Cover and bake.” What onions? The video does not show onions and the rest of the description does not say anything about onions other than the onions that go into the sauce. So where do these other onions go?

  3. Easy to make and to kick it up I add some bacon bits and used a pint of cream and less broth, and a bit of cayenne pepper. My 3 sons inhaled 13 x 9 deep dish in 20 minutes and they said it tasted excellent. Can you believe it, they want this at least 3 times a month.5 stars

  4. Freaking amazing! I made this for a special at-home date night for me and my husband and we both absolutely loved it. I have never made scalloped potatoes before and the only other time I have had them was at my wedding, and this recipe came out even better than our wedding potatoes for sure! Highly Recommend, easy to make for new cooks.5 stars

    1. How wonderful Leia! I am so happy to hear you loved this recipe and you found it easy to follow!

  5. This dish has never been one of my favorites, but I was cooking a ham for an event and wanted the perfect side dish that would be familiar to people. I was so surprised how everyone kept going on and on about how good the dish was, Will definitely make this again and using the mandolin to do the cutting made it so quick to put together,5 stars

    1. White, red, or Yukon gold are all potatoes with thin skins and similar textures; they can be used interchangeably in this recipe as they will all hold their shape well. I am so glad you are enjoying this recipe Carol!

  6. I have to hand slice my potatoes, so they end up on the thicker side. I boil them for about 5 minutes before putting everything together. I also sprinkle a few bacon bits into the layers. This turned out so delicious, and it’s easy.5 stars

  7. Made these last night. Excellent. I was at a loss as to what vegetable to use on the side so I added some chopped peppers and mushrooms to the onion and then put some leftover bacon bits and frozen peas on each layer. Delicious5 stars

  8. Definitely the best cream sauce I have ever tasted. The dish turned out great! Lots of second helping requests.5 stars

  9. This was really good. I scaled back the size a little and substituted garlic scapes for onions since I cannot eat onion. I added a little thyme and sage and oregano and dried mustard to the cream sauce. I also put the cheese in the layers — didn’t have cheddar, so used slices of pepper jack in the first layer and some grated Mexican cheeses in the second layer. Added the top layer of cheese in the last 15 minutes as written. I thought it looked a bit dry so added a bit of liquid; this was a mistake — good but slightly soupier than necessary. I had left over Christmas ham in the freezer and sliced that and layered it as traditional scalloped potatoes i.e. alternative potato and cheese slices in each layer.

    Baked an hour covered and 25 minutes uncovered with cheese the last 15. It was VERY tasty. With the salt in the ham, cheese and the half cup of bouillon used as the chicken broth I didn’t add more and it was perfect. Really good.5 stars

  10. I would definitely say double the sauce or use smaller pan. I just got done putting this together and was only able do two layers. I had enough potatoes and room in pan to do one to two more layers but no sauce.3 stars

    1. I had the same problem not enough sauce, but I noticed after the first layer. So I added more cream and little broth to stretch it out. It worked out perfect.5 stars

  11. There are no directions or a video showing how to prepare the potatoes for this recipe.
    I know how but I’m sure there are those out there that could use some guidance .
    People of ages cook.

    1. Hi Lisa, you can find the video for this recipe by scrolling to the bottom of the recipe or clicking the video icon at the top of the post. I hope this helps!

  12. I do not measure and I do things my own way. For those of us like me this is a fantastic guideline to create your own version. For those of you who do measure and follow recipes, this is a solid one. Trust it. For a nice twist simply use a smoked cheddar. It was really nice! I know everyone’s taste is different but we liked it a lot.5 stars

    1. Yes, the cooking time would decrease slightly. You’ll want to ensure that the potatoes are tender in the middle (poke it with a fork or butter knife). They will still likely need at least an hour to cook through. Let us know how it goes!

  13. Don’t you hate it when recipes don’t tell you the temperature to bake an item, only just for a certain time?

    1. Hi Frank, the first instruction includes the temperature. 1. Preheat oven to 350˚F. Hope that helps.

  14. Absolutely amazing!!! I’ve never made scalloped potatoes until now and this recipe is absolutely incredible the only thing I did was add an extra garlic clove as we love garlic. Definitely recommend thank you for sharing your recipe ❤️5 stars

  15. You need to go back to the drawing board. The scalloped potatoes were the worst .I followed your recipe to the T…seems it needs DOUBLE the cream sauce….very disappointed….I could have WINGED it better than this.
    The best I can do with a HALF 9×13 pan of dry potatoes…..try to flip it into a soup of some kind…..if you would like my photos ….I can prove this isn’t what you assured to be at all ……bummer dinner !!1 star

    1. How disappointing Wendy, I’m sorry this didn’t work out for you. This recipe has been made thousands of times and based on the reviews, it doesn’t appear that other readers have had the same problem.

      1/3 of the cream sauce should be added to each layer so you should not have had any dry potatoes without sauce. You could certainly double the sauce to your liking.

    1. We cover the potatoes to help them steam and that helps them cook a little faster! I hope this helps Taylor.
