Creamy Instant Pot Mashed Potatoes

The Easiest & Creamiest Instant Pot Mashed Potatoes Recipe

There’s something uniquely comforting about a warm, fluffy bowl of mashed potatoes. This classic side dish evokes cherished childhood memories, graces countless holiday tables, and simply tastes incredible. While some prefer a bold, flavor-packed version like Jalapeno Cheddar Mashed Potatoes, others, like myself, lean towards the timeless classic, perhaps with an extra kick of garlic, similar to these Garlicky Mashed Potatoes. And for those who simply adore gravy, any variation will do as long as it’s generously drizzled over the top!

My Instant Pot has become an indispensable kitchen tool recently, transforming the way I prepare meals. From savory main dishes like Instant Pot Pork Tenderloin (which, by the way, pairs perfectly with these potatoes!) to quick weeknight sides, it consistently delivers. So, naturally, I decided it was time to master a classic side dish in it: creamy mashed potatoes. This method not only simplifies the process but also frees up valuable stove-top space, especially during busy holiday cooking.

Why Make Mashed Potatoes in the Instant Pot?

The Instant Pot isn’t just a trend; it’s a game-changer for dishes like mashed potatoes. Here’s why this method is superior:

  • Speed: Significantly reduces cooking time compared to traditional stovetop boiling. You can have perfectly tender potatoes in minutes.
  • Hands-Off Cooking: Once you set the pressure, there’s no need to constantly monitor a boiling pot or worry about boil-overs.
  • Consistent Results: The Instant Pot creates a perfectly steamy environment, ensuring your potatoes cook evenly and become consistently tender throughout.
  • Space-Saving: Frees up stovetop burners, which is especially useful when preparing large meals for holidays or entertaining.
  • Built-in Keep Warm Function: You can make your mashed potatoes ahead of time and keep them warm directly in the Instant Pot until you’re ready to serve, making meal timing a breeze.

Choosing the Best Potatoes for Creamy Mashed Potatoes

Achieving that dreamily creamy texture in your mashed potatoes starts with selecting the right variety of potato. Not all potatoes are created equal when it comes to mashing! You want a potato with a high starch content. Starchy potatoes break down easily when cooked and readily absorb liquids and fats (like butter and cream), resulting in that light, fluffy, and incredibly creamy consistency we all crave.

  • Russet Potatoes: These are a top choice. Their high starch content and dry, mealy texture make them perfect for absorbing moisture and mashing into a fluffy, smooth consistency. They don’t become gummy easily.
  • Yukon Gold Potatoes: Another excellent option, Yukon Golds are slightly less starchy than Russets but have a naturally buttery flavor and creamy texture that’s ideal for mashing. They also hold their shape slightly better, so if you prefer a mashed potato with a little more body, these are fantastic.

Potatoes to Avoid (or use for different dishes):

  • Waxy Potatoes (e.g., Red Bliss, Fingerling, New Potatoes): These varieties have a lower starch content and higher moisture content. While great for roasting, salads, or smashing (where you want them to hold some shape), they tend to become gluey or pasty if you try to mash them until completely smooth. Their cellular structure is more resistant to breaking down, leading to an undesirable texture when over-mashed.

For this recipe, we’ll focus on Russet potatoes, ensuring the perfect foundation for your Instant Pot Mashed Potatoes.

How Do You Make Instant Pot Mashed Potatoes? A Step-by-Step Guide

Making mashed potatoes in your Instant Pot is incredibly straightforward and yields consistently perfect results. Follow these simple steps for a truly delicious side dish:

  1. Prepare the Potatoes: Start with approximately 2-3 pounds of Russet potatoes. Wash them thoroughly. Whether you peel your potatoes or leave the skins on is entirely up to your preference. Many enjoy the rustic texture and added nutrients that the skins provide, especially when well-mashed. If you prefer a smoother, classic mash, go ahead and peel them. For faster and more even cooking, dice the potatoes into roughly 1-inch cubes. If you prefer to cook them whole, you’ll need to adjust the cooking time slightly.
  2. Add Liquid to the Instant Pot: Place the prepared potatoes into the Instant Pot. Add 3/4 cup of water or chicken stock. Using chicken stock will infuse an extra layer of savory flavor into your potatoes. The key here is that these potatoes will NOT need to be drained after cooking. They will absorb this liquid, which contributes to their creaminess and makes them easier to mash.
  3. Pressure Cook: Secure the lid on your Instant Pot and ensure the sealing vent is closed. Set the Instant Pot to cook under high pressure for either 8 minutes if you diced the potatoes into 1-inch cubes, or 20 minutes if you cooked them whole (though dicing is highly recommended for best results and speed).
  4. Natural Release: Once the cooking cycle is complete, allow the pressure cooker to naturally release for 5 minutes. This crucial step helps prevent the potatoes from becoming waterlogged and ensures they retain their structure and flavor. After 5 minutes, carefully quick-release any remaining pressure by turning the venting knob.
  5. Mash to Perfection: Open the Instant Pot. The potatoes should be incredibly fork-tender, with most of the cooking liquid absorbed. Now, it’s time to mash! Mash the potatoes directly in the Instant Pot until they reach your desired consistency. If you love a super creamy, smooth mash, keep going. If you prefer a chunkier texture, mash them just enough to break them down.
  6. Flavor and Season: This is where the magic happens! For a classic flavor profile, mix in 3/4 cup of milk or heavy cream, 4 tablespoons of butter, 2 teaspoons of salt, and a dash of pepper. For an extra punch, add a clove or two of minced garlic. But don’t stop there! Feel free to customize with different herbs (rosemary, thyme, chives), various cheeses (cheddar, Parmesan), a dollop of sour cream for tang, crispy bacon bits, or even roasted garlic for a deeper, sweeter flavor.

Mastering the Mash: Tools and Techniques

You don’t necessarily need a fancy gadget to achieve perfect mashed potatoes. Here are a few ways to get the job done, depending on your desired texture and what you have on hand:

  • Potato Masher: This is the classic tool for a reason. It’s excellent for achieving a consistent, slightly chunky mash. The holes or wires allow you to break down the potatoes without overworking them, which can lead to gumminess.
  • Heavy-Duty Fork: If you don’t own a masher, a sturdy fork can absolutely do the trick! It will take a bit more effort and time, but it’s perfectly capable of breaking down tender potatoes. This method is great for those who enjoy a more rustic, textured mash.
  • Hand Mixer or Electric Mixer: For the ultimate creamy and fluffy mashed potatoes, an electric hand mixer is your best friend. Transfer the cooked potatoes to a large bowl and use the mixer on low speed. Be careful not to overmix, as this can activate too much starch and make your potatoes gummy. Mix just until smooth and fluffy.
  • Whisk: After an initial crush with a fork or masher, a sturdy whisk can help incorporate air and finish the mashing process, especially when adding milk and butter, to create a lighter, fluffier texture.
  • Ricers or Food Mills: These tools are champions for achieving the smoothest, lightest, and lump-free mashed potatoes. They press the cooked potatoes through small holes, separating the starch cells without tearing them, preventing gumminess. It’s the secret weapon of many chefs for truly restaurant-quality mash.

Can You Freeze Mashed Potatoes? Absolutely!

Mashed potatoes are fantastic for meal prepping or saving leftovers. Yes, you can definitely freeze them! The trick is to do it properly to maintain their creamy texture and prevent ice crystals from forming.

How to Freeze Mashed Potatoes:

  1. Cool Completely: Allow your mashed potatoes to cool down completely to room temperature. This is crucial to prevent condensation and ice crystals.
  2. Portion and Pack: For best results, portion them into meal-sized servings. You can use freezer-safe bags or airtight containers. If using bags, press out as much air as possible before sealing them flat. This not only saves space but also allows for quicker thawing.
  3. Freeze: Place the bags or containers in the freezer. They can be stored for up to 3-4 months.

Thawing and Reheating Frozen Mashed Potatoes:

  1. Thaw: The best way to thaw frozen mashed potatoes is overnight in the refrigerator.
  2. Reheat on Stovetop: Transfer the thawed potatoes to a saucepan over low-medium heat. Add a splash of milk or cream and a pat of butter, stirring frequently until heated through and creamy again.
  3. Reheat in Oven: Place thawed mashed potatoes in an oven-safe dish, cover with foil, and bake at 350°F (175°C) for 20-30 minutes, or until hot. Stir halfway through.
  4. Reheat in Microwave: For individual portions, microwave in short bursts, stirring often, until heated through. Add a little milk or butter if needed.
