Instant Pot Mashed Potatoes Recipe
Ingredients

Instructions
- Prep the potatoes
Peel the potatoes, cut them into even 1 inch pieces so they cook at the same rate, and place them in the Instant Pot inner pot. Adding even sized pieces prevents undercooked or mushy spots.
- Add cooking liquid
Pour in 1 cup of water, ensuring the potatoes are submerged about halfway. This creates the steam needed for quick, even cooking without turning the mash gummy.
- Seal and cook
Secure the lid, set the valve to sealing, and select high pressure for 12 minutes. This builds pressure and cooks the potatoes until fork tender while locking in moisture.
- Quick release carefully
Use a protected hand to turn the valve to venting so the pressure drops quickly. Listen for the hiss and check that the float valve drops before opening to avoid a hot steam surprise.
- Drain any excess liquid
Open the lid and let the potatoes sit for a minute, then tip the inner pot slightly to pour off any remaining water. Removing extra liquid prevents a thin, starchy texture.
- Mash gently
Add the softened butter, salt, pepper, and garlic powder, then use a potato masher or sturdy fork to mash while stirring. Stop while the potatoes still have small lumps; they will become creamier as you stir in the warm milk.
- Stir in warm milk
Slowly pour in the warmed milk and fold it into the potatoes with a silicone spatula. The gentle heat from the milk helps create a light, fluffy texture without overworking the starch.
- Finish and serve
Taste and adjust seasoning with an extra pinch of salt or butter if needed, then transfer to a warmed bowl. Garnish with chives, parsley, or cheddar right before serving to keep the surface glossy and inviting.
Substitutions and variations
- Use Yukon Gold potatoes for a naturally buttery flavor and slightly smoother texture.
- Swap whole milk with heavy cream for a richer, silkier mash.
- Replace butter with olive oil or vegan butter to keep the recipe plant based.
- Use salt free seasoning or fresh herbs instead of garlic powder for different flavor profiles.
Chloe's tips
- Do not overcook the potatoes in the pressure cooker, because they will continue to break down as you mash, so slightly firm is better than mushy.
- Warm the milk in the microwave for about 30 seconds; adding warm liquid helps the mash stay smooth and avoids shocking the hot potatoes.
- For restaurant style fluffiness, finish with a pass of a hand mixer or a quick whip with a fork rather than heavy aggressive mashing.
- If the mash feels thick, add a tablespoon or two more warm milk or stock until you reach your perfect spoon dipping consistency.
How to store it
- Store leftover mashed potatoes in an airtight container in the refrigerator for up to 3 days.
- Reheat gently on the stovetop over low heat, adding a splash of milk or broth to refresh the texture, and stir well before serving.
Serving suggestions
These creamy potatoes pair beautifully with roasted chicken, juicy steaks, or a simple weeknight veggie tray.
- Ladle into a warm bowl and crown with a pat of butter for an instant silky surface.
- Sprinkle with freshly cracked black pepper and chopped chives for a polished look.
- Serve alongside roasted turkey, grilled pork chops, or a stack of veggie skewers for a complete plate.
Frequently asked questions
Can I use the potato cooking water instead of milk?
Yes, using a bit of the starchy potato cooking water mixed with warm milk gives extra flavor and helps create a creamy texture without adding extra dairy.
Why did my mash turn out gummy
Gummy texture often comes from overworking the potatoes or using high starch potatoes that were overcooked. Mash gently and avoid overcooking in the pot.
Can I make this in the Instant Pot with the sauté function only
You can cook potatoes on the sauté function, but the pressure cook function is much faster and better at giving fluffy, tender results with less hands on time.
How do I prevent a grainy appearance
Warm your milk before adding it, mash while the potatoes are still hot, and avoid over mixing, which can develop too much starch and make the mash look grainy.
