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.

The Best Potatoes 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.

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.

Serving Suggestions

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”.

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.

Uncover and bake for another 20 minutes or until the top is lightly browned.

  1. Made this for New Year’s Eve as a side dish for a NY Strip steak.
    I used Yukon gold potatoes and a cheese mix of half cheddar/half Gruyere.
    If this is your first time making it, I would suggest giving yourself some more pre-prep time for gathering the ingredients, measuring them out, washing the potatoes, etc.
    I really liked this process with the sauce on the stove and adding the potatoes to it. I have used other recipes where I would have to put the sliced potatoes in water to make sure they didn’t brown and then having to dry them while other prep was going on. The sauce was gorgeous!
    I sliced the potatoes rather thin (thinner then those pictured here), so I was able to take the foil off after 50 minutes, shaving some bake time.
    In sum, as the recipe states: absolute Perfection!
    These potatoes will be made for every holiday.

  2. I followed this recipe exactly. I read probably 50 reviews for any helpful hints. It tasted good when it got done, but it took WAY longer than the recipe claimed. Kind of ruined Christmas dinner when everything else is done and the potatoes take almost an hour longer than expected. Potatoes were thinly sliced, baking dish was the right size. I finally put them in a bigger dish, so they weren’t as thick in the dish and put the oven up to 400. They were tasty, but not worth over 2 hours of cooking. Serves me right for trying a new recipe for guests.

    1. Hi Mary, it’s inconceivable that thinly sliced potatoes would take 2 hours to cook at 400 F. I assure you, the problem does not lie with the recipe; it sounds like your oven is having some issues.

  3. I made these for Christmas dinner last night. However, I changed the servings to eight and the measures accordingly. However, I made ahead and refrigerated overnight and there seemed to be too much liquid even after baking and letting sit. The flavor was so delicious. I will try again with maybe less Liquid ( milk and cream). Any suggestions?

    1. Hi Julie, the amount of liquid depends on the variety of potato you’re using – e.g., Russets will absorb more liquid thank Yukon Golds – but even so, if there was an “excessive” amount of liquid something was off in the conversion calculations.

  4. Can’t wait to make this to accompany duck breast on Christmas day!

    One question: What is the approximate weight of the 1 1/2 cups of cheese? Different graters – box grater vs Microplane vs food processor grater blade – produce quite different volumes of cheese. Example: The difference in volume from grating a given weight of cheese on my Microplane “coarse” vs “extra coarse” graters is substantial.

    Thank you!

    1. Hi Curtis, I haven’t weighed the cheese but cheddar is usually grated using a box grater, so it’s very “coarse”. Also this recipe doesn’t remotely require that kind of precision – whether you add a little more or a little less cheese it will be delicious either way!

  5. I made this for Thanksgiving dinner, using a Gruyere cheese blend. I really don’t care for food preparation tasks, but the recipe is simple and the result was well worth it! I have made this dish twice now, and my only issue with it is that does not yield more helpings =>

  6. Made this for a dinner party and it got rave reviews! I made it a few hours early and kept it in the fridge until I was ready to bake. They stayed warm for about an hour before serving and it was perfect. AMAZING recipe!

    1. Hi Jacqueline, if the pan is a larger then it will be roughly the same cooking time. If it’s the same size pan and the potatoes will be in there in a much thicker/deeper layer, then plan on about 10 extra minutes and then check for doneness by sticking a sharp knife down into the potatoes to see if they’re tender. If not, continue cooking.
