One of the cardinal rules of good potatoes au gratin is that it cannot be dry.  The cheesy cream sauce needs to ooze out.  Not run out all over the plate in a big wet mess, but just slowly oooooze out.  Here is a classic creamy potatoes au gratin recipe at its very best!

I don’t think I’ve ever met a person who doesn’t like potatoes.  I’ve met plenty of picky eaters, but even the pickiest will eat potatoes in one form or the other.  However they’re prepared, they’re the perfect comfort food.  And combined with cream and cheese, they’re simply heavenly.

Au Gratin Potatoes vs. Scalloped Potatoes 

The two have come to be confused and are often used interchangeably as any online search will show.  But they are two different dishes.  Similar but different.  The primary difference lies in the addition of cheese.  Au gratin potatoes include cream and cheese whereas scalloped potatoes are simpler, featuring only cream.

One way to look at it is that with au gratin you get everything scalloped has plus more – deliciously more!  Au gratin potatoes are always my first choice.

Which Potatoes Are Best For Au Gratin Potatoes?

Many recipes call for Russet potatoes.  My favorite is the Yukon Gold potato and I’ll tell you why.  You want to select a potato that has a moderate amount starch in it so that it both absorbs and thickens the sauce.  This will prevent the sauce from running all over the plate.  Potatoes that are very low in starch, like some varieties of fingerlings and red potatoes, will have a hard time absorbing the liquid which increases the risk of ending up with something more akin to au gratin soup (though this can be mitigated by adding a little more flour and/or increasing cooking time).  You also want a potato that will to some extent hold its shape and doesn’t fall apart and turn to mush.  And that’s the challenge with using Russets for things like au gratin potatoes and scalloped potatoes. Russets Potatoes are really high in starch and as a result do not hold their shape.  That’s why they’re not a good option potato salads and it’s for that same reason that they’re really not ideal for au gratin potatoes.  Yukon Golds, having a moderate amount of starch are a great choice.  They’re not so low in starch that they won’t absorb the liquids and they not so high in starch that they’ll fall apart.  In other words, they’re kind of a “Goldilocks” variety of potatoes, which is why they’re so versatile in use.

In the picture below are some lovely Yukon Golds from my garden.

Can You Make Au Gratin Potatoes Ahead of Time?

YES! Au gratin potatoes are the perfect make ahead potato side dish!  Simply assemble the dish a day ahead of time, cover it tightly with plastic wrap and then bake it the next day.  Increase the baking time a little to account for the dish being cold. You can also set it out on the counter and let it sit at room temperature for about an hour before baking while you’re prepping other things.  And don’t worry if the potatoes are a little discolored, you won’t notice it once the potatoes are cooked.

For even better results we recommend par-baking the dish first.  That means you’ll bake it 3/4 of the way, remove it from the oven, let it cool completely, cover and refrigerate, and then bake it the rest of the way the following day.  The potatoes will absorb more of the liquid but you can mitigate this by adding about 1/4 cup extra cream.

Au Gratin Potatoes Recipe

Let’s get started!

Dice the onions, mince the garlic, and thinly slice the potatoes.  You can slice the potatoes by hand or you can use a kitchen mandolin to do the slicing.  It makes the job faster and easier and ensures they’re sliced the same width.  THIS ONE is the same one I bought in Germany and took back to the States with me – I love it.  It’s also Cook’s Illustrated’s “Top Choice”.

THIS ONE is about half the cost and will also do the job just fine.

Heat the butter in a large saucepan over medium-high heat and add the onions and cook until soft and translucent, 5-6 minutes.  Add the garlic and cook for another minute.

Add the flour and stir to combine.  Cook for a minute or two.

Add the milk and cream, stirring continually to prevent clumping.  Slowly bring to a boil, reduce the heat and simmer until slightly thickened.

Add the cheddar cheese, parmesan cheese and salt and stir until melted.

  1. Was too soupy and began to separate. There are so many recipes for au gratin potatoes. I wouldn’t use this one.

    I did like my substitution of shallots for onions.

  2. Hello
    The written recipe is different than the notes written step by step. When do you add the onions and garlic?
    Thank you

  3. This was amazing. Added a total of 5 garlic cloves and did the Gruyere/half Emmentaler combo. I also added some pepper and freshly shredded and grated all the cheese myself. This was phenomenal! This will definitely be on the Easter menu and easily on our rotation!

  4. I just made this with half and half and whole milk. I used about a Tbsp of Worcestershire sauce, a squirt of Dijon mustard, an onion sliced but not diced, and about 4 oz.of diced ham. I added about 6 oz. of cheddar and a leftover chunk of Mexican Blanco. Outstanding! Thank you!

  5. Has anyone used canned sliced potatoes for this recipe? What modifications would I need if using pre sliced canned potatoes. Those potatoes are already fairly tender

  6. Can I make this dish 2 days ahead and par cook it and put it in the fridge. Your blog says I can do it one day ahead but just checking about 2 days ahead. I make this often and love it. Just trying to get a head start on Xmas dinner. Thank you. Valerie

  7. Hello I am going to make this for thanksgiving I currently have a block of gouda/parmesean cheese its a blend I got from Costco my question is do you think I need to add third cheese?
    Thanks in advance!

  8. I have not tried this dish as of yet, I have no cream but I do have coconut cream, would that work seeing as I cannot have dairy cream, too heavy and effects me. I am ok with a little milk, but not dairy cream.

  9. I have made this dish for years but knowing how brilliant YOUR recipes always are I tried your version. Absolutely streets ahead and my husband asks for it often. In fact it is SO good we often have just this with added smoked lardons for supper in front of the telly and a good film. You make simple things spécial and you can do no wrong chez nous!

  10. WOWWIE wowser.. What a great recipe. A helpful hint when making this…having everything measured out & cheese grated before starting. It’s difficult doing it while stirring as the cream mixture thickens.
    The Gruyere really makes this dish!! I didn’t what was called for so I used a bit of Gouda & Muenster as well.. but the Gruyere stands out. The next time I make it. I’m going to use a lot less salt. Usually the potatoes help soak up the salt but this was a tad too much for us.
    Thank you for posting this. I’m glad I chose this one over the other 80 billion that popped up. :)

  11. I made this for a BBQ. OMG absolutely delicious and gourmet.

    Even better the next day. I used gruyere and a parmesan cheese.

    I added two extra garlic cloves.

    Thank you

  12. I doubled this recipe and cubed the potatos . I also addied 1/8 tsp cayenne pepper for a little more kick. It was not hot but I could’ve added a 1/4tsp instead. Thank you for this wonderful creamy delicious Au Gratin potato recipe. It was a hit at our family cabin!

  13. These were the best au gratin potatoes I’ve ever made. My whole family loved them. I followed your suggestion and used half cheddar and half gruyere cheese. I used my food processor to slice the potatoes. My husband asked me when I was making again. Thanks so much for the recipe!

  14. If I add cubed cooked ham to your recipe, how much should I add and do I omit any liquid becauce of the adding of ham?

  15. I have one question about this wonderful recipe, the picture shows some little green specs but nothing in the ingredients appear therefore I was wondering if these are bits of green onion tops or peas. Can anyone help me with an answer? Thank you
