You might remember Fluffy Mashed Potatoes in which I teach you how to make mashed potatoes with a ricer and how to prep them ahead of time. Or my Creamy Whole30 Mashed Potatoes where we discover all the secrets to not only make mashed potatoes in the Instant Pot but how to make them sooooo good even without all the dairy of a traditional recipe.

If those two recipes had a baby, and that baby was a little spicy and tasted delicious, it would be these Wasabi Mashed Potatoes.

Disclosure: no babies were harmed in the making of these taters.

If you find yourself in the rare position of having leftover mashed potatoes, consider making Simple Shepherd’s Pie With Turkey. Or, just eat them on the floor of your closet hiding from your kids. 

You got choices, that’s what I am saying.

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.

What is Wasabi?

Wasabi is a Japanese plant with a green root that is ground up to make an amazing paste or powder. It is very similar to horseradish in taste, so if you’re unable to find it locally, feel free to sub in equal amounts of horseradish. And then called them horseradish mashed potatoes and impress your friends!

If your heart is set on using wasabi but you can only find wasabi powder, that will work too. You’ll want to premix it according to the directions on the package. For best results, use cold water and let it sit for five minutes before adding to the mashed potatoes.

WHAT ARE THE BEST POTATOES FOR MAKING MASHED POTATOES?

Here is the truth friends, 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, and yellow.

I prefer to peel mine, but if you’re a peels-in kind of person, you do you!

Pro Tips/Recipe Notes

  • Can you make wasabi mashed potatoes in the Instant Pot? Yes, follow the directions as outlined in my Instant Pot Whole30 Mashed Potatoes.
  • Start with 1 tsp of wasabi paste and taste before adding any more. Since I have kiddos, I like to mix up the mashed potatoes and set some aside for them before adding the wasabi.
  • Feel free to add in garlic while the potatoes are cooking to take this dish to the next level.
  • If you consume dairy, adding 1/2 cup of shredded Parmesan cheese would be ammmmmmazing!

Ingredients

  • 3 pounds potatoes {mixture russet, gold, yellow}
  • 4 tbsp unsalted butter
  • 1 cup heavy cream {warmed}
  • 1 tsp wasabi paste
  • salt and pepper to taste

Instructions

  • Peel and rinse your potatoes. Cut into 1-inch pieces. Place potatoes in a stockpot full of COLD water.

  • Drain the potatoes and add the butter and cream to the pan. Heat on low until the butter has melted.
  • Fill your ricer halfway with potatoes, insert the pressing disc, and gently press the handles over the pot to create potato "rice". Repeat until all potatoes have been pressed.
  • Add the wasabi paste to the pot. 
  • Use a large spatula and fold all the ingredients together until incorporated. If your potatoes seem a little dry, feel free to add a bit more melted butter or heated cream until they have reached your desired consistency.
