Instant Pot Potatoes Au Gratin are cheesy scalloped potatoes with a crisp topping that you make entirely in the pressure cooker. An easy holiday side dish!

Some of my favorite Instant Pot recipes are side dishes, like these cheesy scalloped potatoes. What’s different about this au gratin potato recipe is it’s made completely in the Instant Pot Duo Crisp, from start to finish, including broiling at the end!

I usually only make au gratin potatoes as a holiday side dish or in a casserole with leftover holiday ham. These cheesy potatoes take over an hour to cook in the oven only about 25 minutes in the pressure cooker!

So, if you’re short on time or oven space, Instant Pot au gratin potatoes are for you! You can also make air fryer potatoes au gratin with an air fryer oven. Can you tell I’m kind of obsessed with kitchen gadgets lately?

Au Gratin Potatoes vs Scalloped

So, what’s the difference between scalloped potatoes and au gratin potatoes? In a nutshell, au gratin potatoes are made with cheese and sometimes topped with breadcrumbs for extra crunch. Scalloped potatoes traditionally are made without cheese.

Many people just say cheesy scalloped potatoes. And honestly, that’s fine!

How to Make Cheesy Scalloped Potatoes in the Instant Pot

This quick au gratin potatoes recipe uses the pot-in-pot cooking method for the pressure cooker. You’ll need a pan that fits inside your Instant Pot, and you’ll need to use the trivet.

First, cut your potatoes super thin. A mandoline slicer works best for this, but if you don’t have one, cut them as thin as possible.

Next, butter your baking dish well, and layer the sliced potatoes so that they overlap just slightly. Then, season each layer as you go.

What Cheese is Best for Au Gratin Potatoes

I use a mix of cheddar for flavor and Colby Jack for creaminess. You can use Gruyere, Monterey Jack or even shredded Parmesan on top.

Pour a little cream over each potato layer, and add a thin layer of shredded cheese over the cream. You should get about 5 layers of potatoes.

On the 5th layer, add the remaining cheese, or more cheese if you want, and pour the remaining cream on top. Now, set your pan on the trivet, and pressure cook your potatoes.

After pressure cooking, the potatoes should be fork tender. If they’re not, you can cook them for another 5 minutes or until they’re done.

Now, change your lid, and place the air fryer lid on the Instant Pot. Broil for about 5 minutes or until the cheese is bubbling and brown. Go even longer or add breadcrumbs for a crispier crust.

Let the potatoes rest for about 5 minutes or so. The sauce will thicken even more, and you’ll have perfect au gratin potatoes!

What if I Don’t Have a Duo Crisp or Crisp Lid?

No problem! Just transfer the potatoes to the oven, and broil them for about 5 minutes or until the top layer is crispy.

    I really was just curious about, hmm, what does this taste like so I made it. OMG! I have never eaten a scratch version of Au Gratin potatoes. I can, however, describe the ones in the brown box with the dehydrated potato chips with powdered seasonings. I have a very picky family and I had stomach surgery 10 days prior. Everyone knew what it was as soon as they tasted it. I don’t know what was amiss but my potatoes would not cook. I rant them at high for 25 minutes, became agitated and put them back on for 35 mins. Browning them with the lid id brilliant and pretty. Everyone liked it and they finished the batch in 1 day.5 stars

  2. Melinda says:

    Can you make this with butternut squash instead of potatoes?

    1. Dee says:

      You probably can, but I haven’t tried it.


    Where do you get a “Browning” lid for a InstaPot?
    Can you get one after market?

    1. Dee says:

      Yes! It’s called a Crisp Lid, and I think Amazon and Walmart both carry them.

  4. James says:

    What a hit and you can do it all in the Duo! Making these again very soon.5 stars
