Like so many other families, weekdays in my house can get really hectic. Between after-school activities, snack time, and homework…sometimes I feel like there just aren’t enough hours in the day!

When dinner time rolls around, I need something that’s filling, easy-to-make, and that comes together quickly. I rely a lot on my Ninja Foodi in times like these.

It makes preparing dinner so much faster!

When I’ve got the main dish covered (air fryer chicken legs, chuck roast, and pork chops are a few of my go-tos), it’s time to think about what sides to pair with it.

Veggies are a must (green beans or broccoli, anyone?), and so is a filling carb. I like potatoes in any form, but mashed are some of my favorites.

Imagine my joy when I discovered that you can make mashed potatoes in the Ninja Foodi!

The pressure cooker takes a lot of time spent waiting on the potatoes to boil out of the equation. This recipe cuts the time it takes to make this dish in half, and I’m all about it.

If you want another variation, make our Instant Pot Garlic Mashed Potatoes in your Foodi or Rosemary Mashed Potatoes as instead!

You can even turn your leftovers into twice baked mashed potatoes!

Here’s what I’m going to teach you in this post:

  • The 5 key ingredients (plus water) you’ll need to make Ninja Foodi mashed potatoes at home. 
  • Step-by-step instructions on how to make mashed potatoes in the Ninja Foodi, plus the specific settings you’ll use, and cooking times.
  • Seasoning variation ideas for some seriously tasty results.

Once you make my Ninja Foodi mashed potatoes, you’ll want to serve them every week! Everyone in my family loves these — even my pickiest eaters gobble them up and ask for seconds.

I used the Ninja Foodi 8QT Pressure Cooker and Air Fryer for this recipe. I find this to be a great size for my family of four!

How To Make Ninja Foodi Mashed Potatoes

A full printable version of this recipe with ingredient measurements is available at the bottom of this post.

STEP ONE: Make sure to wash, peel, and dice the potatoes before getting started. The pieces should be approximately 1 inch in size. Place them in the inner pot of the Ninja Foodi (the gray bowl), then pour in enough water to cover the potatoes. They won’t be completely submerged, and that’s okay!

STEP TWO: Close the lid and set it to pressure cook on High for 5 minutes with the valve closed. When the timer goes off, perform a manual release for 5 minutes. This step is very important — don’t skip it! Do a quick release for about 2 and a half minutes to release the remaining pressure.

STEP THREE: Remove the potatoes from the Ninja Foodi and place them in a mixing bowl. As I don’t have a silicone mixing tool for mashing potatoes, I don’t want to scratch my inner bowl. If you do, you can simply drain the water from the bowl and add the rest of the ingredients before mixing.

STEP FOUR: Add the melted butter, milk, and chicken broth, then mix on low with a hand mixer until smooth. Add any additional seasonings here (see below for my favorite add-ons) and pour the mashed potatoes back into the Foodi. Use the stovetop setting to warm until your desired temperature. Serve and enjoy!

Ninja Foodi Mashed Potatoes Seasoning Variations

One of the best parts of making mashed potatoes in the Ninja Foodi is that they act as a blank canvas. Serve as is, or add whatever extra seasonings you like!

Here are some seasoning ideas to inspire you:

  • Garlic or onion powder 
  • Bacon bits and cheese (mozzarella or Colby Jack are delicious)
  • Fresh onions or garlic — or chopped green onions as a garnish
  • Oregano, basil, thyme, or parsley

Can You Mash Potatoes In A Ninja Foodi?

Remember: the inner pot of your Ninja Foodi will get scratched if you don’t use a silicon mashing tool to make Ninja Foodi mashed potatoes.

You can either invest in one or simply remove the potatoes from the pressure cooker and mix them with a traditional hand mixer.

You can pour the potatoes back inside once they are mashed to reheat.

How Do You Keep Mashed Potatoes Warm In A Ninja Foodi?

You can use the stovetop setting to keep your Ninja Foodi mashed potatoes warm before you’re ready to serve.

Make sure to put the lid on to keep all of that warmth inside until you’re ready to eat.

Can You Over Whip Mashed Potatoes?

Yes. Make sure to mix the potatoes, butter, milk, and chicken broth until smooth, but do not overmix them.

You could end up with gluey results if you aren’t careful. It’s always better to undermix instead of overdoing it!
