Dishes like hearty casseroles, warming soups, and especially rich, creamy mashed potatoes are always at the top of my craving list, particularly when the weather outside is cold and blustery.

This can be a challenge to fit into a busy dinner schedule, leading to the frustrating realization that you’ve run out of time to get them ready.

Frequently Asked Questions About Pressure Cooker Mashed Potatoes
Can I make mashed potatoes in a slow cooker instead?
If you prefer the “set it and forget it” approach of a slow cooker, you’re in luck! I have a fantastic and equally delicious recipe for slow cooker mashed potatoes that you can find here. It offers a wonderfully simple and hands-off way to achieve creamy mashed potatoes, perfect for days when you need to start cooking earlier in the day.

What is the best way to store leftover mashed potatoes?
Proper storage is key to enjoying your delicious leftovers. After serving, allow any remaining mashed potatoes to cool slightly before transferring them to an airtight container. Be sure to label the container with the date. This recipe for mashed potatoes should keep well in the refrigerator for up to 3 days. To prevent bacterial growth, it’s crucial to refrigerate food within 1 hour after serving. When reheating, a splash of milk or cream can help restore their creamy texture, and gently warming them on the stovetop or in the microwave works best.

How many servings does this recipe yield?
The serving size for this recipe can vary significantly based on individual appetites and whether it’s part of a larger meal or a standalone dish. This particular recipe is designed to generously feed our family of five young adults, usually leaving a small amount for second helpings or next-day leftovers. Given the hearty appetites of young adults, we typically don’t end up with an abundance of leftovers from most dishes. However, this quantity proved perfect for our family, ensuring everyone got their fill and we still had a portion to savor the following day. I appreciate that this recipe helps keep portion sizes in check, as it’s all too easy to overindulge when it comes to a comforting classic like mashed potatoes.
Instant Pot Potatoes: Speed and Convenience

Can this recipe be doubled for a larger crowd?
Unfortunately, due to the inherent space constraints within most standard pressure cookers (typically 6-quart models), I cannot recommend doubling this recipe. While I would love nothing more than to quadruple this delicious recipe because of how much I adore it, there simply isn’t enough internal volume to accommodate that many potatoes while maintaining efficient and safe pressure cooking. Overfilling your pressure cooker can lead to unsafe conditions and uneven cooking. If you need to prepare a larger quantity, your best bet is to cook multiple batches or use two pressure cookers simultaneously, if you have them.

What if I prefer creamier mashed potatoes?
Achieving your desired level of creaminess is all about adjusting the liquid. If you enjoy thinner, more luxuriant mashed potatoes, similar to those often pictured alongside a hearty beef dish, you can easily increase the amount of milk. I recommend gradually adding anywhere from 1 cup to 1-1/2 cups of milk while mashing the potatoes. The key is to add it slowly and in small increments, continuously mashing and observing the texture. This gradual addition ensures you don’t accidentally end up with an overly liquid consistency once your mixing is complete. For an even richer taste and smoother texture, you can also experiment with adding a tablespoon of butter, cream cheese, or even a dollop of sour cream along with the milk.

How to Make Pressure Cooker Mashed Potatoes: A Step-by-Step Guide
- Begin by pouring the specified amount of cold water into the bottom of your pressure cooker insert. This water creates the steam necessary for pressure cooking.
- Place a trivet or a sturdy vegetable steamer basket into the bottom of the pot. This keeps the potatoes elevated above the water. If you don’t have one, use the metal rack that came with your cooker and form a small bowl with aluminum foil to prevent diced potatoes from falling through the gaps.
- Thoroughly peel and dice your potatoes into roughly equal-sized pieces (about 1-inch cubes for even cooking). Place the diced potatoes on the rack, ensuring they do not exceed the pressure cooker’s maximum fill line. Overfilling can be dangerous and lead to improper cooking.
- Securely close the lid of your pressure cooker and lock it into place. Double-check that the steam release valve is set to the “Sealing” position. Set the manual cooking time to 7 minutes on high pressure, then step back and allow the appliance to do its work.
- Once the cooking cycle is complete, carefully perform a quick pressure release by turning the steam release valve to the “Venting” position. Stand clear of the valve as a forceful stream of hot steam will be released.
- Once all the steam has been released and the float valve has dropped, safely remove the lid, tilting it away from your face and any overhead cabinets to avoid contact with residual steam.
- Carefully scoop out the perfectly cooked, tender potatoes and transfer them into a large mixing bowl.
- Add the milk and, if desired, a tablespoon of mayonnaise for extra creaminess. Season generously with salt and pepper to taste. Using a hand-held potato masher, mash the potatoes until they reach your desired consistency – smooth and creamy, or slightly lumpy if preferred. Continue mashing until all lumps are removed and the ingredients are well incorporated.

Can I use a different kind of potato for this recipe?
Absolutely! While russet potatoes are fantastic for a classic fluffy mash, you can definitely experiment with other varieties. Sometimes, I enjoy adding a handful of red potatoes to the mix, leaving their skins on to impart extra flavor, color, and a delightful textural contrast. You can also successfully substitute russet potatoes with Idaho potatoes, which are very similar in starch content and yield a similar fluffy result, or with Yukon Gold potatoes. Yukon Golds are renowned for their naturally buttery flavor and creamy texture, making them an excellent choice if you prefer a richer, denser mash. Each potato type will lend a slightly different character to your mashed potatoes, so feel free to choose based on your preference or what you have on hand.
What kind of gravy do you recommend with these mashed potatoes?
Mashed potatoes and gravy are a match made in culinary heaven! I’m a firm believer in keeping things simple and delicious in the kitchen, which is why I often opt for an Easy Gravy Recipe that I think you’ll adore. Its straightforward preparation perfectly complements the ease of these pressure cooker mashed potatoes. For specific occasions, you might also want to explore my rich Turkey Gravy, which is ideal for holiday meals, or my savory Pork Onion Gravy for a heartier pairing.

Notes
*This recipe was created using the 6-quart instant pot. If you are using a different size pot or a different pressure cooker brand entirely, cooking times may be off by a couple of minutes.
**Live at High Altitude – Because water boils at a lower temperature at high altitudes, and pressure cooking requires water to boil in order to work, some foods may need a little more cooking time. When pressure cooking at high altitudes you want to make sure to add 5 percent to your cook time for every 1,000 feet above 2,000 feet elevation. For example, when we lived at 4,000+ feet I would add 10 percent to my cook time. For a recipe that called for 20-minutes of cooking time, I would then cook for 22 minutes. When pressure cooking, 1-2 minutes can make all the difference in a recipe, unlike when cooking by traditional methods.
