Instant Pot Cheesy Potatoes Au Gratin made easy in your pressure cooker! These cheesy scalloped potatoes are thinly sliced, coated in a rich, creamy, cheese sauce, and crowned with a crispy panko breadcrumb topping. These Instant Pot Cheesy Potatoes Au Gratin are the perfect side dish for a holiday dinner—or to make any weeknight meal special!
I love to serve these Instant Pot Scalloped Potatoes with ham for an Easter or Christmas holiday dinner. However, these potatoes are so quick and easy, they’re in regular rotation on my weeknight menu as well.
The potatoes cook in only 5 minutes in the pressure cooker, and you make the cheese sauce right in the pressure cooking pot.
How to Make Cheesy Au Gratin Potatoes in an Instant Pot or Electric Pressure Cooker
This Instant Pot Cheesy Scalloped Potatoes recipe will work in any brand of electric pressure cooker, including the Instant Pot, Ninja Foodi, or Mealthy MultiPot.
I love cooking potatoes in the pressure cooker! They cook quickly, evenly, and when you use a steamer basket, they don’t break down around the edges.
Do I Have to Cook the Potatoes in a Steamer Basket?
I strongly recommend making the potatoes in a steamer basket. Getting them up out of the liquid makes a difference in texture of the potatoes.
If you don’t have a steamer basket, you can use the trivet that came with your pressure cooker. In a pinch, just add the potatoes directly to the liquid in the bottom of the pot.
How to Brown the Au Gratin Topping
If you have a Mealthy CrispLid, Ninja Foodi, or Instant Pot Duo Crisp, you can add the topping and brown these easy scalloped potatoes right in your pot! This is perfect for pot luck meals where you serve directly from the pressure cooker!
If you’re using a traditional broiler, pour the potato-cheese mixture into an oven-safe baking dish and broil at 350ºF until golden brown. Remember, once it starts to brown, it will change quickly, so keep a close watch on it!

Can I Half or Double the Recipe?
To make a half batch: To avoid the burn notice, you will need to use at least 1 cup of liquid so your pot will come to pressure. After cooking, remove half of the liquid and proceed with the cheese sauce.
To make a double batch: You can easily double this recipe with no change to the cook time. Just be sure not to fill your cooking pot above the max fill line.
If you’re making this in an 8-quart or larger pressure cooker, you may need additional liquid for your pot to come to pressure. Doubling the recipe is an easy way to achieve this!
What’s the Difference Between Cheesy Scalloped Potatoes and Cheesy Potatoes Au Gratin?
Many people use these terms interchangeably. Technically, scalloped potatoes are just cooked in a rich cream sauce with no cheese. And au gratin means “covered with breadcrumbs and/or cheese and browned.”
However, you can use this recipe to make either cheesy scalloped potatoes or au gratin potatoes. Just omit the breadcrumbs for scalloped potatoes and add them for potatoes au gratin.
What Potatoes to Use for Homemade Scalloped Potatoes?
I recommend making pressure cooker au gratin potatoes with fresh, sliced potatoes. If you have a mandoline, they slice up quick and easy!
💡 Pro Tip: Save time on these cheesy au gratin potatoes by using a package of refrigerated, fresh sliced potatoes! (If your brand is sliced thinner than ⅛ inch, you’ll need to cut down on the cook time by a minute or two.)
Russet potatoes (aka Idaho potatoes) are an excellent choice! However, if there’s a great sale on Yukon Golds, those will give you a slightly different texture but should work just fine.
I don’t recommend substituting red potatoes. (Try my Instant Pot Garlic Roasted Red Potatoes instead!)
And no matter what potato you choose, be sure to scrub them well before slicing.
