Easy Mashed Potatoes in Instant Pot
There is nothing like a bowl of creamy, buttery mashed potatoes. I honestly think I could eat them with every meal, especially if roast beef is on the menu. My family is the same way, so you could say creamy mashed potatoes are my specialty – I make them pretty often!
When I need to whip up potatoes in a pinch for an easy side dish for Sunday supper or the holidays, these Instapot mashed potatoes are my go-to.
The only prep work you’ll do is peeling the potatoes. No need to cut them – they go into the pot whole! Your pressure cooker does the rest of the work for you in just 12 minutes.
If you’re looking for the perfect Instant Pot mashed potatoes recipe, this is the one. I love making them this way (especially with Instant Pot Turkey Breast over the holidays!).
🥔 What are the best potatoes for mashed potatoes?
The best potatoes for mashed potatoes are dense and smooth, like Russet or Yukon gold. They come out perfectly when you’re making Instant Pot boiled potatoes for mashing.
Can you keep mashed potatoes warm in Instant Pot?
Yes. You can keep your pressure cooker on the “Keep Warm” setting with the potatoes in the pot for up to 2 hours.
This is great for when you want to make them ahead of time and keep them warm for when guests arrive!
Can you make mashed potatoes without milk?
Yes. If you’re leaving out the milk, use extra butter. You can also mix in chicken stock or even drippings from turkey to add a little more liquid to the potatoes, which helps when mashing them!
Using a potato ricer or potato masher will also help you get that perfect creamy consistency without milk.
How long do mashed potatoes last in the fridge?
Your leftovers will last 3 to 5 days in the refrigerator, if you don’t gobble them up before then!
Store in an air-tight container and add a pat of butter when reheating.
🔥 Reheating Mashed Potatoes
You can reheat your potatoes in the Instant Pot! They will come out just as creamy and buttery as if fresh.
If you’re reheating several servings, use the Keep Warm function and let your potatoes heat over time in the pot. Stir occasionally to heat through and add a splash of more milk if necessary, plus more butter.
If you’re reheating just a smaller serving amount, place the leftover potatoes in a heat-proof dish and follow these steps:
- Fluff them up with a fork first.
- Pour 1 cup water into the pot, then add your trivet.
- Place the heatproof dish of potatoes on the trivet and use the Steam function for 5 minutes.
⭐ Family Foodie Tips
- No need to cut your potatoes. After peeling, you can cook them whole in the Instant Pot. That’s part of what makes this recipe so convenient!
Be careful not to over-mix your potatoes. If you mix them on too high of a speed or for too long, they will come out gluey! Mix gently for the best potatoes.
❄ How to Freeze
You can freeze your potatoes in individual portions or in one big portion to reheat when you need it! Make sure to add plenty of milk and butter. This helps the potatoes freeze well.
- Scoop potatoes into individual servings onto a parchment-lined baking sheet with a spoon. Freeze until solid (this usually takes a few hours or overnight), then transfer to a freezer bag or container labeled with the freezing date.
- Transfer cooked potatoes to a freezer-safe container or bag and label with the date. I like to place them in the same dish I’ll bake them in later, wrapped in foil and plastic wrap.
When reheating from frozen, reheat in the oven straight out of the freezer at 350°F for 30 minutes. Heat covered with foil.
