Instant Pot Au Gratin Potatoes- Quick & Easy Side Dish
I’m going to be honest here, if it is just my little family at dinner (like most nights) side dishes usually fall to the wayside. Heck, these day’s we are lucky if I make something fresh for dinner instead of re heating leftovers of some recipe I had been testing earlier in the week!
In fact, remember those Instant Pot Grape Jelly Meatballs I shared a few weeks ago? Yeah..we ate that appetizer for dinner. FOUR nights in a row. A testament to how much we like them, I guess, right?
When it comes to side dishes, I am all for anything POTATOES. I can go for these Baked Potato Chips, mashed potatoes or these au gratin potatoes anytime.
Speaking of Au Gratin potatoes.. These are super suuuuper easy. We are talking a little slicing and dumping. Honestly, peeling and slicing the potatoes is as hard as it gets.
Not to mention fast! The potatoes will cook in the Instant Pot for 0 minutes. Lightening speed!
You and your family will love this rich and creamy side dish as an addition to any meal!
How to make Au Gratin Potatoes in your Instant Pot
To make Au Gratin Potatoes in the Instant Pot, first you’ll need to peel and slice your potatoes.
Slice your potatoes thinly. You are aiming for somewhere in between 1/8″ and 1/4″ of an inch thick.
Next, into the Instant Pot goes chicken broth followed by the potatoes. Add minced onion, garlic, salt and pepper on top of that.
Cook on Manual HIGH for 0 minutes.
Cooking for 0 minutes explained: When cooking with the Instant Pot, it takes time for the pot to come to pressure (the pin will pop up). The cook time stated in any given recipe is just the time it is held at pressure.
If a recipe states to cook for 6 minutes, this means that the pot will be pressurized for 6 minutes.
When cooking for 0 minutes, this means that the pot will heat up in order to come to pressure and then it will beep indicating that the cook cycle has finished.
Release the pressure once the pot has beeped.
Now it is time to create that creamy sauce! I added a little evaporated milk to the broth but you could definitely substitute heavy cream if you’d rather.
Carefully stir the broth and potatoes until it is well combined.
Next you’ll add a total of 1 cup of cheese. This is where your creativity can really shine! I like to use half parmesan cheese and half cheddar. These are two that I always have on hand.
Previously, I have made the Au Gratin Potatoes using part Sharp White Cheddar cheese and completely loved the outcome! I think pepper jack would be a fun twist, too.
Pour the potatoes into an oven safe dish, sprinkle with a little extra cheese.
Broil the potatoes until the sauce is bubbling and the cheese is melty and browned.
The sauce will thicken more as it cools. The Au Gratin Potatoes are best if they rest for 10 minutes before serving.. but I’ll admit I totally ate half the pan standing over the sink immediately after these photos were taken.
Garnish with parsley, if desired. ?

So good and easy to make. I noticed when I went to print the recipe, I could adjust the number of servings for the recipe. BRILLIANT!!! My husband and I are empty nesters and cooking for 2 instead of 5 is so hard! Thank you for making that easier for me, you are amazing Karli!!
Oh, good!! I am so happy it was helpful for you! Thanks for the comment and stars, Elizabeth!
Would the liquid needed be the same with a smaller batch? i remember somewhere it said about the instantpot needing enough liquid to come to pressure. Just wondered if you tried it and if it worked out for you.
I would use the same amount of liquid for the smaller batch to insure that the Instant Pot comes to pressure. Nothing wrong with a little extra cheesy sauce!
Made this tonight! Soooo much easier than the traditional way! Delicious!! Keeping for another day……soon I’m sure!
Yay! I am so glad you enjoyed them, Shannon!
Can’t wait to try this! Looks fabulous!! Does it matter if you use shredded or grated Parmesan?
The cheese is used to help thicken the sauce, so definitely use fresh parmesan that will melt into the sauce- not the powdered stuff. Hope you enjoy!!
Do you use grated or shredded Parmesan cheese?
Shredded. 🙂
I made these for dinner tonight and they’re amazing! Easy to make and mix together in the IP. Thank you for sharing this recipe, I’ll definitely being making this again.
So happy to hear this, Pamela! 🙂
Super eady – very yummy. I added ham while cookingin IP. Little too much sauce, next time will drain half of broth before adding milk n cheese. Can always add later if needed. Tasted great O pressure cook time was perfect.
I’m glad you enjoyed them, Leslie!! Thanks for your notes on the recipe. 🙂
I have a combination Instant Pot/ air fryer. Can I make this a 1 dish meal and do the broiling in the air fryer? I just recently purchased it and haven’t got it all figured out yet.
You should be able to!! I am not too familiar with the air fryer lid, but you should be able to crisp up the top using that!
My family loves this recipe versus the old way, and so do I! It saves me so much time. I add some ham to it while it’s cooking in the pressure cooker to make it a meal – their absolute favorite meal! Thanks so much for the recipe!
Thank you Tera, I’m so glad that you like it. Keep on cooking!
I botched it. I watched a video of you making this and then I could not find it. I do not know what I did wrong but my pot would not come to pressure because I managed to burn the cheeses on the bottom. I was supposed to add the cheese before sealing, correct? Man, I really wanted this to work =/ lol
Hi Gayle- you’ll add the cheese after everything has cooked. That will fix it for next time!
My entire life I have tried and failed to make good au gratin potatoes! Under cooked or over cooked potatoes, lumpy cheese sauce and never very good. This recipe is AMAZING and comes out perfect every time. Cheesy, tender potatoes and so yummy!
YES, I’m so glad this worked for you. Great job and happy cooking Janna!
