An Easy Classic

Of all the potato side dishes from Oven Roasted Potatoes to Perfect Baked Potatoes, nothing says comfort food like creamy side of scalloped potatoes (except maybe creamy buttery mashed potatoes).

So exactly what are Scalloped Potatoes? Thought to have originated in England, the word ‘scallop’ is basically a definition for how the potato is sliced. Thin and uniformly cut potatoes are layered in a casserole dish and then 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 but tend to break apart more (but still taste good).
  • Onions Onions add a lot of flavor to this recipe and are a classic ingredient. Slice very thinly.
  • Cream Sauce A quick cream sauce made with flour, butter, milk and broth. 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.
  • Seasonings Simple seasonings in this recipe include salt, pepper, onion, garlic. Add in your own favorites including thyme, rosemary, parsley.

How to Make Scalloped Potatoes

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

  1. Thinly slice potatoes & onions.
  2. Make homemade sauce (recipe below)
  3. Layer potatoes, onions and sauce. Cover and bake.
  4. Remove foil and bake a bit more, this step creates the delicious brown top 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 just 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  will potatoes to a bit faster.

To Make Scalloped Potatoes Ahead of Time

To make these ahead of time (and keep cooking fast on the day of serving) we have tested partially baking them with great results.

  • Bake the dish covered for 50-60 minutes.
  • Remove from the oven and cool completely on the counter (leave them covered, the steam will help to finish cooking).
  • Cover well and refrigerate.
  • On the day of serving, remove from the fridge at least 30 minutes before baking. Bake uncovered about 35 minutes or until heated through.

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. Thanks for yet another great recipe! This was lovely and received compliments all around. I add a bit of parmesan cheese on top, but would have been great as is. It did take a lot longer in the oven than specified, but we had it in there with a pork roast so that could have been the reason.

    As a tip, I used the slicing function on my food processor and it made the job of prepping the potatoes so much easier as well! It only took 5 mins to get through a pile of potatoes and was easier than even a mandolin.5 stars

  2. Good and easy recipe, will definitely make again. Would be good with bacon, cheese and a little garlic also.5 stars

  3. I followed the recipe exactly. It had no taste and took a lot longer then it said in the recipe. Don’t understand all the great reviews.1 star

  4. Loved by the family for Easter yesterday; made as directed. Sprinkled the middle layer with pepper & Spike seasoning. Broiled with gruyere cheese. Might add a bit of paprika (hot or smoked) the next time. **this recipe is a fantastic reason to invest in a mandolin, if you’ve not got one.

  5. I’ve been cooking for many years and this is THE BEST scalloped potato recipe I have ever made! I made it with red potatoes and added a little more garlic since I have some wonderful homegrown mild garlic. This recipe was so easy and just the right amount of sauce— great idea for the addition of chicken both and onion for wonderful flavor. Everyone loved it at our Easter dinner today. Thank you sooo much for posting this incredible recipe. I would give it 10 stars if I could!5 stars

  6. Hi there! I’m very excited to make this recipe. I’m just wondering if I can assemble an hour or two before baking or if needs to be baked right away?
    Thanks!5 stars

  7. Great recipie! I did add one layer only of sliced Colby cheese in the middle. I did not want it to be cheesy but I wanted to have some. I added parsley flakes and paprika on the top to make it pretty. It went really well with Easter dinner.5 stars

  8. I’m excited to be making this recipe tomorrow (Easter) to have with ham. The ingredients sounds like an amazing flavor is going to be enjoyed! The one dish I never got the recipe for from my mom was her scalloped potatoes and she is passed away now I can’t wait to try these!5 stars

  9. Excellent recipe just as is, these are only suggestions. If you have one, slice your potatoes and onion on a mandoline at 1/8 inch thick. Slice onion into onion rings, from top to bottom of onion. Next separate before you sauté. I quartered rings before I sautéed them to prevent them from bunching together. I recommend to increase your roux mixture by half to allow for even coverage between layers. I added two ingredients to help enhance this excellent recipe. One teaspoon of nutmeg to your sauce and a layer of shredded ham between potato layers. This was an incredible addition for our family Easter dinner. Chow!5 stars

    1. Hi Janice, you will find the make ahead information in the post. This would be at the same temperature as listed in the recipe, 350F.

      Bake the dish covered for 50-60 minutes. Remove from the oven and cool completely on the counter. Cover well and refrigerate. On the day of serving, remove from the fridge at least 30 minutes before baking. Bake uncovered about 35 minutes or until heated through.

      Enjoy the potatoes, they’re a favorite of mine for sure!

    1. A foil pan does not hold the heat as well as a regular pan (or glass baking dish) and can take longer to cook.
