Why this recipe Stands Out

  • Save Time: You can now serve up homemade mashed potatoes more often, with only 8 minutes of cook time and 5 ingredients.
  • Save Money: Only 5 basic pantry ingredients are needed; no cream cheese or sour cream is needed.
  • Less Calories: You’ll only need milk and butter for the creamiest mashed potatoes; no sour cream, cream cheese, or heavy cream involved.
  • Big Flavors: This simple recipe delivers on the flavor front, whether you choose to use amazing homemade gravy or not.

Key Recipe Ingredients

This Instant Pot mashed potatoes recipe boasts a pure buttery flavor with creamy texture. Here’s what you’ll need:

  • Russet potatoes or Yukon Gold potatoes: Russet potatoes are high in starch and low in moisture, resulting in a fluffier and drier texture. Yukon Golds are medium in starch level and low moister, which yields a creamier texture. The choice is yours, and if you don’t want to choose, use a combination of both.
  • Regular strength chicken broth or stock: many recipes use water, but we love the flavor that a good broth provides. It also adds moisture/liquid to the mashed potatoes without adding more fat.
  • Milk: feel free to use either whole milk or low-fat milk, but try to avoid fat-free milk, as you do need some fat for creaminess. Whole milk is the favorite here.
  • Real butter. Of course butter and plenty of it. Though it might sound like a lot of butter, it’s actually less than most mashed potato recipes. Start with the amount listed, and add more melted drizzles at the end if you’d like – who doesn’t like?

Substitutions and Variations

Your 5-ingredient Instant Pot mashed potatoes recipe is awesome as-is. Just a simple drizzle of butter on top or homemade gravy is drool-worthy and tastes incredible. However. If you would like to jazz things up once in awhile, here are flavor options to help you make that happen:

  • Roasted garlic. This is the ultimate add-on for mashed potatoes, if you’re going to add on. It’s crazy easy to roast whole heads of garlic ahead of time. If you’re a garlic fiend like myself, feel free to go wild and roast an extra head of garlic to make garlic-butter to spread on everything.
  • Freshly chopped herbs: play with your favorite herbs, including chives, parsley, or thyme. Just sprinkle a bit of it in at the end – remember that less is more when it comes to mashed potatoes.
  • Cream: If you really want to go all out with creaminess, you can add in a bit of sour cream or almost-melted cream cheese.
  • Cheese: Sprinkle in a bit of freshly grated parmesan cheese or other cheese, for all the cheese lovers.

Step-By-Step Recipe Instructions

  1. Pour broth into the inner pot of your Instant Pot. Place potatoes onto steamer rack. Close lid and lock in place. Turn steam release handle/valve to correct position, if needed. Cook on high pressure for 8 minutes. 
  2. While potatoes are cooking, combine milk and softened butter slices into a saucepan over low heat. Stir until butter is completely melted and milk is warmed through. Turn heat off and keep warm.
  3. Once pressure cooker is done, do a Quick Release. Gently remove lid and remove steamer rack, sliding potatoes into the pot with broth. Use a potato masher to mash potatoes.
  4. Add warm milk/butter mixture and a generous sprinkle of kosher salt – any optional seasonings can be added now as well.Keeping Instant Pot on “warm,” continue to hand-mash potatoes to your desired texture.

Stovetop Cooking Option

You can opt to make this recipe using stovetop alternative as well. Simply boil peeled/cubed potatoes in a large pot of salted water for 15 minutes, or just until potatoes are fork-tender. Drain and proceed with recipe as written.

Prep Time: 7 minutes
Cook Time: 8 minutes
Servings: 8
Author: Amy Dong

Ingredients  

  • ½ cup chicken stock, regular strength
  • 3 lbs russet or yukon gold potatoes, peeled and cut into 2-inch pieces
  • ½ cup milk, whole preferred
  • ½ cup butter, sliced and softened, plus more for drizzling
  • Kosher salt
  • Optional seasonings: freshly ground black pepper, garlic powder or roasted garlic, chopped herbs of your choice

Instructions

  • Pour broth into the inner pot of your Instant Pot. Place potatoes onto steamer rack. Close lid and lock in place. Turn steam release handle/valve to correct position, if needed. Cook on high pressure for 8 minutes. 
  • While potatoes are cooking, combine milk and softened butter slices into a saucepan over low heat. Stir until butter is completely melted and milk is warmed through. Turn heat off and keep warm.
  • Once pressure cooker is done, do a Quick Release. Gently remove lid and remove steamer rack, sliding potatoes into the pot with broth. Use a potato masher to mash potatoes.
  • Add warm milk/butter mixture and a generous sprinkle of kosher salt – any optional seasonings can be added now as well.
    Keeping Instant Pot on "warm," continue to hand-mash potatoes to your desired texture. Taste and add more salt, if needed. Serve with drizzle of melted butter or gravy, if desired.

Notes

  • Russet potatoes tend to result in fluffier, lighter texture, while yukon gold potatoes will yield a creamier consistency. The choice is yours; you can try combining both types of potatoes as well.
  • If you’d like to make roasted garlic mashed potatoes, you can roast the garlic a day ahead of time.
  • Over-mashing potatoes can lead to gumminess, so be sure to watch carefully as you mash and stop as soon as your potatoes turn creamy.
  • Finished mashed potatoes can be kept warm in the Instant Pot for 1-2 hours before serving, though the sooner you can serve it, the better. If needed, you can stir in a bit more liquid (broth or milk) to mashed potatoes before serving.
  • Stovetop option: boil peeled/cubed potatoes in a large pot of salted water for 15 minutes, or just until potatoes are fork-tender. Drain and proceed with recipe as written.
