Potatoes cook quickly under pressure, and the time needed in a pressure cooker varies depending on whether you leave them whole or cut them into pieces. So how much time to cook potatoes in pressure cooker? The short answer is 5 to 10 minutes for cubed potatoes and 10 to 15 minutes for whole potatoes once the cooker reaches full pressure.
In this guide you will learn exact timings for every type of potato, plus simple steps that work on stove-top and electric models.
Quick Timing Chart For Pressure Cooked Potatoes
Use this chart as your starting point. Times begin when the cooker reaches full pressure, not when you turn on the heat.
- Cubed potatoes (1 inch pieces): 5 to 7 minutes
- Sliced potatoes (1/4 inch): 3 to 5 minutes
- Whole baby potatoes: 8 to 10 minutes
- Whole medium potatoes: 10 to 12 minutes
- Whole large potatoes: 12 to 15 minutes
- Potatoes for mashing (quartered): 8 to 10 minutes
These times are for white and yellow potatoes. Red potatoes hold there shape well and cook in similar time. Sweet potatoes need a bit longer, usually 10 to 12 minutes for chunks.
How Much Time To Cook Potatoes In Pressure Cooker
The exact time depends on three things: the size of the pieces, the type of potato, and the pressure level you use. Smaller pieces cook faster because heat reaches the center quicker.
Stove-Top Pressure Cooker Times
Stove-top cookers run at 15 PSI, which is high pressure. They cook potatoes faster then electric models.
- Diced potatoes: 4 to 6 minutes
- Whole small potatoes: 8 minutes
- Whole medium potatoes: 10 minutes
- Whole large potatoes: 12 to 14 minutes
Use a natural release for whole potatoes. A quick release can crack the skins and leave the centers undercooked.
Electric Pressure Cooker Times
Electric cookers like the Instant Pot run at 10 to 12 PSI. Add about 1 to 2 minutes to the stove-top times.
- Diced potatoes: 5 to 7 minutes
- Whole small potatoes: 9 to 10 minutes
- Whole medium potatoes: 11 to 12 minutes
- Whole large potatoes: 14 to 15 minutes
Electric models take longer to come to pressure, so plan for 10 extra minutes of preheat time.
Times For Specific Potato Dishes
Mashed Potatoes
Peel and quarter the potatoes. Add 1 cup of water or broth. Cook for 8 minutes on high pressure. Use a quick release, then mash with butter and milk.
Potato Salad
Cut potatoes into 1 inch cubes. Cook for 5 minutes. Quick release right away so they stay firm and do not turn mushy.
Whole Potatoes For Baking Or Stuffing
Prick the skins with a fork. Add 1 cup of water and set them on a trivet. Cook large potatoes for 14 minutes. Let the pressure come down on its own for 10 minutes.
Step By Step Method For Perfect Potatoes
- Wash and scrub the potatoes under cold water.
- Cut them into even pieces if you want faster cooking.
- Pour 1 cup of water into the pressure cooker.
- Place potatoes in a steamer basket or on a trivet above the water.
- Lock the lid and set the valve to sealing.
- Cook on high pressure for the time listed above.
- Release pressure based on the dish you are making.
- Check doneness with a fork. It should slide in with no resistance.
If the fork meets resistance, lock the lid and cook for 2 more minutes.
Tips To Get The Timing Right Every Time
- Cut pieces the same size so they cook evenly.
- Do not fill the cooker more then two-thirds full.
- Always use at least 1 cup of liquid to build steam.
- Natural release works best for whole potatoes.
- Quick release works best for cubes and slices.
- Add 1 teaspoon of salt to the water for better flavor.
- Cold potatoes from the fridge may need 1 extra minute.
Altitude also plays a role. If you live above 3,000 feet, add 5 percent more time. Above 6,000 feet, add 10 percent.
Common Mistakes To Avoid
Many people overcook potatoes because they forget that pressure cooking is fast. A few extra minutes can turn firm cubes into mush.
- Do not skip the trivet. Potatoes sitting directly in water get soggy.
- Do not overfill the pot. Steam needs room to move.
- Do not use a quick release on whole potatoes.
- Do not cut potatoes into tiny pieces unless you want them very soft.
Another common slip is not accounting for come-up time. The clock only starts at full pressure, so a 10 minute recipe can take 25 minutes total.
How To Tell When Potatoes Are Done
Use a fork or a paring knife. Push it into the thickest part of the potato. If it goes in smooth with no push back, the potato is done.
For mashed potatoes, you want them slightly softer so they break apart easy. For potato salad, you want them just tender so they hold there shape.
If you are unsure, open the cooker and test one piece. You can always cook for another minute, but you cannot undo overcooking.
Final Word On Pressure Cooker Potato Times
Potatoes are one of the easiest foods to cook under pressure once you know the basic numbers. Cubes take 5 to 7 minutes, whole medium potatoes take 10 to 12 minutes, and large whole potatoes take 12 to 15 minutes.
Stick to the chart, use the right release method, and test with a fork before serving. With a little practice you will get perfect potatoes every single time, whether you are making mash, salad, or a simple side dish for dinner.
