Super creamy, and oh so comforting, you’re going to love these Whole30 mashed potatoes! No one will be able to tell they’re also dairy-free and vegan. Secrets are fun!

Making mashed potatoes in the Instant Pot isn’t a giant time saver compared to stovetop mashed taters. It cuts maybe 5 minutes off the total time. 

But having an Instant Pot option is great when you’re out of space on your stove, or you just want to be able to make and keep mashed potatoes warm in one container.

Want to make this process even faster? Prep the potatoes ahead of time! You can even freeze them months in advance for the ultimate prep. Related: Freezing Potatoes. And if you’re up for a challenge you can even learn about canning potatoes for a super-fast dish.

Can You Have Mashed Potatoes on Whole30?

Yes! The program changed in summer 2014 to allow potatoes onto the list of compliant foods. While starchy foods aren’t generally the best thing to fill your diet with, incorporating potatoes occasionally during a Whole30 round is fine.

There is some debate as to whether white potatoes are allowed on a paleo diet, but it appears to be a personal choice. You know, like every freaking thing in life! If you’re looking for something without potatoes, you’ll love this Easy Carrot Mash.

What Are The Best Potatoes For Making Mashed Potatoes?

You should be using a mixture of different kinds of potatoes. Starchy, waxy, and baking spuds all add their own perfect quality to this delectable side dish. I usually use a mix of russets, golds, yellow, and a few red potatoes (those buggers are delicious, but HARD to peel). We use this same mix to make Instant Pot Potato Salad.

If it is in your budget, look for organic potatoes, as their conventionally grown cousins are very high on the Dirty Dozen. This recipe used half-peeled russet potatoes and half unpeeled yellow potatoes.

Secure the lid and set the vent to “sealing”. Press manual>high pressure>8 minutes.

When the time is up, wait 2 minutes and then using a clean kitchen towel, flip the vent to “venting”. Allow it to rest until the pressure gauge drops. Using oven mitts, remove the insert and drain the potatoes into a strainer/colander.

Place the insert back into the Instant Pot and press “Saute”. Add the ghee (plant-based butter for vegan diets), milk, and salt. Allow it to cook until warmed through (about 1 minute).

Pro Tips/Recipe Notes

  • Leave the finished mashed potatoes in the Instant Pot and press the “keep warm” setting if you’d like to serve them within an hour or so. Stir occasionally to prevent any hot spots.
  • To make them a day or so ahead of time, allow the mashed potatoes to fully cool and then store them in an air-tight container in the fridge. Reheat in the oven at 300 degrees F.
  • If you aren’t dairy-free, feel free to use your favorite milk and butter in the same measurements as listed in the recipe card.
  • Serve these spuds with Instant Pot Beef Tips and Gravy for a super cozy and comforting dinner.
