FAQ – 15 Questions About Cooking Potatoes in an Instant Pot
How long do I cook whole potatoes in an Instant Pot?
On my experience, small whole potatoes take 6–8 minutes, medium ones go for 10–12. I always let the pressure release naturally for about 10 minutes—it helps finish the cooking gently.
Can I cook potatoes with the skin on?
Absolutely. I do this all the time, especially for red or Yukon Gold potatoes. The skin softens and adds flavor and texture—great for rustic mashes or salads.
How long do cubed potatoes take in the Instant Pot?
I always set them for 3 to 5 minutes on high pressure. Quick release, then straight into mashing or a soup pot. Super reliable.
Should I use a trivet or put potatoes directly in the water?
For whole potatoes, I place them on the trivet with a cup of water. For cubed or mashed-style, I just drop them right into the water so they steam evenly.
Can I overcook potatoes in the Instant Pot?
Oh, yes—and they’ll turn to glue real fast. I always start on the lower end of the timing range and test with a fork. You can always add a minute if needed.
What kind of potatoes work best for the Instant Pot?
For mashed, I swear by Yukon Golds. For salads, baby reds are unbeatable. Russets work for baking or when you want that fluffy texture.
Can I cook sweet potatoes the same way?
Pretty close! I usually go for 15 minutes on high pressure for medium sweet potatoes, and let the pressure release naturally.
Do I need to peel potatoes before pressure cooking?
Not unless you want to. I often leave the skin on for nutrition and texture. If I’m doing a smooth mash, I’ll peel them after—they slip right off when hot.
How much water do I need in the Instant Pot?
Just 1 cup is plenty for most recipes. I always make sure the water doesn’t touch the potatoes on the trivet—unless I’m making mash.
How do I keep potatoes from getting mushy?
Watch your time and cut size! I always cut my potatoes evenly and keep a close eye—short pressure times make all the difference.
Can I make potato salad in the Instant Pot?
I do it all the time. 6–7 minutes for baby potatoes, quick release, then cool them quickly. Toss with a little vinegar while warm for flavor punch.
Can I cook potatoes and other veggies together?
Yes—but I always group similar textures together. Potatoes with carrots or parsnips work great. Softer veggies like zucchini? Add them later.
Can I use the Instant Pot to reheat cooked potatoes?
I have, but I prefer to steam or sauté them. The Instant Pot can be a little aggressive unless you’re careful with timing.
Do I need to poke holes in the potatoes before cooking?
Nope. I never do in the Instant Pot. The steam pressure cooks them evenly without any bursting.
Can I store cooked potatoes from the Instant Pot?
Yes! I keep them in the fridge for up to 5 days. I use them in breakfast hashes, soups, or quick mashed potatoes during the week.
