How Many Minutes To Cook Potatoes In Pressure Cooker

by

Getting the timing right for potatoes in a pressure cooker depends on whether you want them sliced, cubed, or whole. Most people ask how many minutes to cook potatoes in pressure cooker once they realize the answer changes with the cut size and the type of potato. The good news is that pressure cooking is fast. You can have tender potatoes in as little as 4 minutes for slices and up to 20 minutes for large whole ones.

Below you will find exact times, simple steps, and tips that work for russet, Yukon gold, red, and baby potatoes. Use this guide as your quick reference chart.

How Many Minutes To Cook Potatoes In Pressure Cooker

The total time depends on three things: cut size, potato variety, and whether you use high or low pressure. Most electric pressure cookers run at high pressure (10 to 12 psi). Stovetop models can go higher. The times below assume high pressure and a natural release unless noted.

Sliced Potatoes (1/4 Inch Thick)

  • Cook time: 4 to 5 minutes
  • Release: Quick release
  • Best for: Scalloped potatoes, gratins, and quick side dishes

Slices cook very fast. If you go past 5 minutes, they turn to mush. Use a steamer basket and add 1 cup of water to the pot.

Cubed Potatoes (1 Inch Chunks)

  • Cook time: 6 to 8 minutes
  • Release: Quick release
  • Best for: Potato salad, soups, and breakfast hash

One inch cubes are the most common cut. Six minutes gives firm cubes for salad. Eight minutes gives softer cubes for mashing or soups. Check one cube with a fork at the 6 minute mark.

Whole Baby Potatoes (1 To 2 Inches Wide)

  • Cook time: 8 to 10 minutes
  • Release: Quick release
  • Best for: Roasted-style sides, buttered potatoes, and meal prep

Prick each baby potato once with a fork. This keeps the skin from splitting. Add salt to the water for better flavor.

Whole Medium Potatoes (6 To 8 Ounces)

  • Cook time: 12 to 15 minutes
  • Release: Natural release for 5 minutes, then quick release
  • Best for: Baked potatoes, mashing, and potato skins

Prick the skin a few times. Place them on a trivet with 1 cup of water. A natural release helps them finish evenly without a gummy center.

Whole Large Potatoes (10 Ounces Or More)

  • Cook time: 15 to 20 minutes
  • Release: Natural release for 10 minutes, then quick release
  • Best for: Big baked potatoes and large batches of mash

Large russets take the longest. If you stack them, add 2 extra minutes. Do not overcrowd the pot. Leave space for steam to move around.

Step By Step: How To Pressure Cook Potatoes

  1. Wash and scrub the potatoes under cold water. Peel them only if you want peeled potatoes.
  2. Cut them to the size you need. Slices, cubes, or whole. Keep the pieces the same size so they cook evenly.
  3. Pour 1 cup of water into the pressure cooker. For stovetop models, use 1 cup as well. Never skip the water.
  4. Place the potatoes in a steamer basket or on a trivet. This keeps them out of the water and stops them from getting waterlogged.
  5. Add 1 teaspoon of salt over the potatoes. You can also add garlic cloves or a bay leaf for flavor.
  6. Lock the lid and set the valve to sealing. Choose high pressure and set the timer based on the chart above.
  7. Let the pressure come up. This takes 5 to 10 minutes on most electric cookers. The timer starts only when full pressure is reached.
  8. Release the pressure as noted for your cut size. Quick release for small pieces. Natural release for whole potatoes.
  9. Open the lid away from your face. Steam is very hot.
  10. Test doneness with a fork or knife. It should slide in with little resistance. If not done, cook for 1 more minute at high pressure.

Times For Different Potato Varieties

Not all potatoes cook the same. Waxy potatoes hold their shape. Starchy potatoes break down faster. Here is a quick guide.

  • Russet potatoes: Best for baking and mashing. They fall apart easy, so use the lower end of the time range.
  • Yukon gold: A middle ground. Great for cubes and slices. Use the times in the chart above.
  • Red potatoes: Waxy and firm. They need 1 to 2 extra minutes for whole sizes.
  • Baby potatoes: Small and waxy. 8 to 10 minutes whole works well.
  • Sweet potatoes: Not the same as white potatoes. Cubes need 5 to 7 minutes. Whole medium ones need 12 to 15 minutes.

If you mix varieties in one pot, cut them to the same size. Otherwise some pieces will overcook while others stay hard.

Common Mistakes To Avoid

  • Using too little water. One cup is the minimum for most cookers. Less water can cause a burn notice.
  • Forgetting to prick whole potatoes. Trapped steam can make the skin burst.
  • Overcooking cubes. Two extra minutes turns firm cubes into mush.
  • Using quick release on large whole potatoes. They need a natural release to finish in the center.
  • Stacking potatoes too high. Steam needs to move. A single layer or a loose pile works best.
  • Adding too much liquid. Potatoes release water as they cook. A soupy result means you added too much.
  • Not accounting for altitude. Above 3,000 feet, add 1 to 2 minutes to every time in this guide.

Quick Reference Chart

  • Sliced, 1/4 inch: 4 to 5 minutes, quick release
  • Cubed, 1 inch: 6 to 8 minutes, quick release
  • Whole baby, 1 to 2 inches: 8 to 10 minutes, quick release
  • Whole medium, 6 to 8 ounces: 12 to 15 minutes, 5 minute natural release
  • Whole large, 10 ounces plus: 15 to 20 minutes, 10 minute natural release
