These 1-minute Instant Pot mashed potatoes cook at high pressure for one minute, then get mashed with butter and warm milk. They suit Thanksgiving because they free stove space and stay warm in the pot. An Instant Pot is an electric pressure cooker that seals steam to cook food fast. Peel and cube the potatoes first, pressure-cook briefly, then mash right in the insert for easy cleanup.

What does 1-minute mean?
The one minute is only the time at full pressure. The pot also needs time to heat, build pressure, and release. Expect about 15 to 20 minutes from lid-on to mash-ready with small batches. This timing works best for small, even cubes.
Large chunks may stay firm in the center after a very short cook. Cut potatoes into roughly 1-inch pieces for even results. Use quick release when the minute ends. Letting pressure drop naturally continues cooking and can make the potatoes waterlogged. Open the valve promptly, then drain excess liquid if needed.
How do you prep the potatoes?
Choose starchy or all-purpose potatoes such as russets or Yukon Golds. Russets mash fluffy, while Yukon Golds taste buttery and hold shape better. A mix gives both body and smooth texture.
Rinse cut potatoes in cold water to remove surface starch. Add them to the pot with water and salt. Use just enough cold water to barely cover the pieces.
- Peel and cut into even 1-inch cubes
- Rinse, then add to insert with water and a pinch of salt
- Lock lid, set valve to sealing, cook on high pressure for 1 minute
- Quick-release pressure, drain if soupy, then mash
How do you get a creamy texture?
Mash while the potatoes are steaming hot. Use a hand masher for fluffy potatoes with some texture. Avoid a blender or food processor, which can turn potatoes gummy. Warm the milk and melt or soften the butter before adding.
Cold dairy cools the potatoes and mixes unevenly. Add a little at a time until the mash looks smooth but still holds shape. Season in layers. Salt in the cooking water seasons the interior, then adjust after mashing. Add black pepper, roasted garlic, chives, sour cream, or cream cheese only after the base texture is right.

How do you time this for Thanksgiving?
Cook the potatoes when the oven is busy with turkey or sides. The sealed pot does not need watching once it starts. Mash directly in the insert to save a bowl. Use the keep-warm setting for short holding.
Stir before serving and add a splash of warm milk if the edges stiffen. For longer holding, refrigerate and reheat gently with extra milk. Scale with care for a crowd. Fill the insert no more than half full so pressure builds safely. For more than about 3 pounds, cook in two batches rather than packing the pot.
Frequently Asked Questions
Do I need a trivet or steamer basket?
No. Potatoes can cook directly in salted water in the insert, which makes mashing simpler and keeps flavor in the potatoes.
Can I make these dairy-free?
Yes. Use olive oil or dairy-free butter and warm unsweetened plain plant milk, adding small amounts until creamy.
Why are my potatoes gluey?
Uneven pieces, overcooking, or high-speed blending can cause gumminess. Use even cubes, quick-release promptly, and mash by hand.
