The Difference between Scalloped Potatoes and Au Gratin Potatoes

Why is there so much confusion about scalloped potatoes versus Au Gratin Potatoes?  Well, they are very similar.  So, we are calling our dish cheesy scalloped potatoes, and let me explain why we can do that.  We are basically combining the best parts of both dishes.

A traditional scalloped potato dish consists of sliced potatoes layered in a casserole dish and baked with heavy cream and lots of herbs. A traditional Au Gratin Potato dish, on the other hand, has grated cheese sprinkled between the layers, resulting in a cheesy, more decadent dish. In both dishes, the potatoes are cut into rounds, but the potatoes used in scalloped potatoes are often cut a bit thicker than those in au gratin potatoes.

For this recipe, I take a cream sauce and smother it over thick cut potato rounds.  I like to use a mandolin so that our potato slices come out the same every time.  This is seriously the most amazing cheesy scalloped potato recipe that I have ever had.

How to Make Cheesy Scalloped Potatoes

We like to start by creating a layered base of potato and onion.  This evenly distributes the flavors so that every bit is consistent and amazing. 

After you have assembled your masterpiece, you will move over to the saucepan and get started with some melted butter. Then you will mix in flour and salt, creating a base for your cheese sauce. Next milk gets added to the mixture (this is the cream sauce that you normally see in a scalloped potato dish).

Finally, you add in the cheese all at once and stir it all up until its melted. Pour the cream sauce over the potatoes, then cover and cook.  Let it bake for a solid hour and a half.  Throw on the broiler at the end if you want a crisp topping (I always do this but you don’t have to).

Cheesy Scalloped Potatoes and Ham

So many people have asked if this could be combined with Ham.  Without a doubt.  This would be amazing with the addition of ham!  I would maybe cube it and put it in between the rows of potatoes.  Really, all you need to do is add it to the ingredients list, it will incorporate with the rest of the recipe just fine.  That would take this from a side dish to a knock out the main course! 

No matter which way you decide to prepare this cheesy scalloped potatoes dish, you will not be disappointed!  Neither will anyone at your dinner table.  Seriously?  What is there not to love!?

I love to pair this with other holiday favorites like the worlds WORST stuffing, roasted carrots, creamy mashed potatoes and herb butter roasted turkey!

    Hi Amanda – what can i use to substitute regular AP flour? I am on gluten free diet. Also, can I used regular American cheese instead of cheddar cheese?
    Please advise – thank you so much!

  • Dorothy Archambeau says:

    These are amazing! I made them for an Easter dinner and the neighbors raved! They fought over the small amount left over! Thank you! ♥️

  • Frank Westrum says:

    Followed the recipe exactly but when I took the foil off it was full of water. The sauce was thick when I put it on the potatoes. What do you think went wrong?

  • May says:

    I made this tonight for Easter and it was great! My fiance loved it. I cooked it without onion. Baked it in my toaster oven at 390 I also added 2/3 cups more cheese to the cheese sauce. I took the foil off for the last 8 minutes for a more textured top. Yummy!
