for Instant Pot Baked Potatoes
Ingredient List
- 4 medium russet potatoes (800 g total)
- 1 cup (240 ml) water
- 4 g kosher salt guide (optional, for serving)
💡Helpful Tips
- Choose similar size potatoes: this ensures they cook evenly and finish at the same time.
- Do not overcrowd: leave space between potatoes so steam can circulate properly.
- Pierce lightly if very large: this helps prevent internal pressure buildup in oversized potatoes.

How to Cook Instant Pot Baked Potatoes (Step-by-Step Guide)
-
Step 1
Place the potatoes under running water and scrub them thoroughly using your hands or a brush to remove all dirt from the skin.
Make sure to clean every side, especially any small crevices. Do not peel the potatoes - the skin protects the potato and helps keep the inside soft and fluffy during cooking.
Dry each potato completely with a towel. This prevents excess moisture from affecting the texture and ensures even heat distribution during pressure cooking. -
Step 2
Insert the metal trivet into the Instant Pot so the potatoes will not sit directly in the water.
Pour exactly 1 cup (240 ml) of water into the bottom of the pot. This liquid is essential because it creates the steam required to build pressure.
Place the potatoes on the trivet in a single layer. Avoid stacking - each potato should have space around it so steam can circulate evenly. -
Step 3
Close the lid of the Instant Pot securely and turn the valve to the Sealing position.
Select the Pressure Cook (Manual) mode on HIGH pressure. Set the cooking time based on potato size: small - 12 minutes, medium - 13-14 minutes, large - 15 minutes.
Do not open the lid during cooking. The Instant Pot will first build pressure, then begin the timer automatically - this is normal and part of the process. -
Finish
When cooking is finished, wait for 5 minutes without opening the lid - this is called natural pressure release and helps keep the potatoes tender.
After 5 minutes, carefully turn the valve to Venting to release the remaining steam. Always keep your hands away from the steam to avoid burns.
Remove the potatoes using tongs. Cut each one open lengthwise and gently press the sides inward - this step makes the inside light, airy, and fluffy.
Serve immediately while hot, adding salt or toppings as desired.
📌 Common Mistakes When Making Instant Pot Baked Potatoes
Making Instant Pot baked potatoes seems simple, but the final texture depends on several small details: potato size, steam circulation, release method, and the way the potatoes are opened after cooking. Because the Instant Pot cooks with pressurized steam rather than dry oven heat, the technique is slightly different from traditional baked potatoes.
The most common problems are not dramatic failures - they are texture issues. Potatoes may turn out dense in the center, slightly waterlogged on the outside, or less fluffy than expected. In most cases, the cause is not the potato itself, but a setup choice made before or immediately after cooking.
The guide below explains the most frequent mistakes and how to fix them so your Instant Pot baked potatoes come out evenly cooked, soft inside, easy to open, and much closer to the ideal fluffy result.
| Problem | Most Likely Cause | Quick Fix |
|---|---|---|
| Potatoes are unevenly cooked | Different potato sizes were cooked together | Use potatoes of similar size or increase time for larger ones. |
| Texture is wet outside and heavy inside | Potatoes sat too low or were crowded during steaming | Place them on a trivet with space between each potato. |
| Centers are still firm | Cooking time was too short for the potato size | Return to pressure for 2-3 more minutes if needed. |
| Inside is soft but not fluffy | Potatoes were not opened and loosened correctly after cooking | Cut open and gently press the sides inward while hot. |
Using potatoes of very different sizes in the same batch
Pressure cooking works best when all potatoes need roughly the same amount of time. If one potato is much larger than the others, the smaller ones may become overly soft before the large one is fully cooked through.
This creates an inconsistent batch where some potatoes split too much and others remain firm in the center. Even when the timing looks correct on paper, size variation can change the final result noticeably.
Letting the potatoes sit too close to the water or packing them too tightly
Instant Pot baked potatoes should be steamed above the water, not partially submerged in it. If the potatoes are crowded or positioned poorly, steam cannot move evenly around them.
This can lead to patchy texture: one area may feel damp and heavy while another cooks more cleanly. The potatoes may still be edible, but they will not have the even, soft structure most people expect.
Assuming all potatoes need the same exact cooking time
Potato size, density, and even variety can affect how quickly the center softens under pressure. Following one fixed time without checking the actual size of your potatoes can leave the middle undercooked.
This is especially common when using extra-large russet potatoes. The outside may seem ready, but the center can still resist a knife or fork.
Opening the potatoes without fluffing the interior while they are still hot
A cooked potato does not automatically become airy just because it is soft. If it is simply cut and left alone, the inside can remain compact, especially near the center.
The best fluffy texture comes from a small finishing step that loosens the interior while the potato is still hot and the starch is relaxed.
Quick Summary
Better Instant Pot baked potatoes come down to control: use potatoes of similar size, keep them elevated above the water, match the cooking time to their size, and fluff the interior immediately after opening. These small corrections make the difference between potatoes that are merely soft and potatoes that feel properly light, even, and satisfying.
