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. ?

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!
The Cat's Meow says
Delicious! I accidentally put the heavy cream (replacement for evaporated milk) into the IP with all the other ingredients, but realized my mistake before I turned the pot on. Called an IP friend, she suggested pouring out the liquid and adding back a fresh cup of broth (plus any dry ingredients that might have been lost). Worked!! Absolutely yummy!! I’ve never made scalloped potatoes *ever* from scratch and I’m so happy! I doubled the recipe in my 8-qt and saw your instructions (to another user) to double the ingredients and keep the same time. It was perfect. Only had grated Mexican cheese blend on hand — still yummers!
Christie says
Csn i use milk instead of heavy cream?
Cooking with Karli says
YES, I’m so glad this worked for you. Great job and happy cooking Janna!
Karli Bitner says
You definitely can!
Katie C says
I made these last night. They were so very good! Family loved them, too! I used fresh garlic, and half parm/half cheddar. I cut the potatoes (russet) on my mandoline at pretty much exactly halfway between 1/8 and 1/4 inch thick. Cooked exactly as the recipe says, and they were a little less done than I would have liked. I will try cutting them thinner next time, or adding 2 minutes of cook time. Any thoughts on which to try first? This recipe was so good, and so easy, I want it to be perfect!
Karli Bitner says
Hi Katie! I would just cut them a little thinner next time. 🙂 I am glad you enjoyed them!
Steve says
This is not an instant pot recipe.
Karli Bitner says
It is made in the Instant Pot, and then finished in the oven, so I’d call it an Instant Pot recipe.
Jane Clarke says
Can you use any kind of potatoes or should they be russets? We enjoy gold, red and russet. Thanks Jane
Karli Bitner says
Any kind of potato should work!
Christiane Schulze says
If I double the amount of potatoes…do I need to adjust the cooking time??
Gem says
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.
Karli Bitner says
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!
Karli Bitner says
You shouldn’t need to adjust the cook time at all.
Heidi says
how do you cook for 0 minutes?
Karli Bitner says
You’ll just set your Instant Pot to 0. This just means it will take about 10 mintues to heat up, it will come to pressure and once the pressure is reached you will then release the pressure.

I made this last night, so good, even my husband said it was really nice. Which means success. Thankyou
Carol Murray says
love love love this recipe! I used heavy cream and put the instant pot to one minute instead of zero. I will use again and again.
Towanda Brunson says
Made this dish last night and it turned out awesome! I set my timer to 1 minute, will probably do 2-3 minutes next time for a softer potato. I used half a cup of heavy whipping cream instead of the evaporated milk. The broiler browned up the top of the potatoes nicely. My fussy 10 year old daughter asked for seconds, I consider that a win! It will definitely go in our rotation of favorite dishes.
