Are you considering adding another small kitchen appliance to your collection but worried about sacrificing precious counter space? Look no further! The air fryer is the answer, offering incredible versatility and efficiency. With a multi-functional machine, you can effortlessly create these delightful air fryer mashed potatoes and even perfectly baked potatoes right in your own kitchen. Once you discover the magic of air frying, you’ll be eager to explore more air fryer recipes, and we’ll be here to guide you.
The Ultimate Convenience: Air Fryer Mashed Potatoes with Ninja Foodi & Cosori
As a true advocate for multi-functional appliances, I can attest to the sheer convenience they bring to any kitchen. This recipe works flawlessly whether you opt for classic Russet potatoes or the vibrant sweet potatoes pictured here. While any air fryer brand will do, we’ll highlight the capabilities of popular models like the Ninja Foodi and Cosori, which truly elevate the cooking experience.
If you own a Ninja Foodi, you’re in for a treat, as it often features dual functionalities. Beyond air frying, you can also prepare incredibly fluffy pressure cooker mashed potatoes within the same unit. These innovative machines come with two distinct lids, each designed for a specific cooking function. When using the air crisp function, you’ll achieve beautifully crispy skins – a bonus if you plan to repurpose them into savory potato skins. Otherwise, the inside will still be wonderfully soft and ready for mashing. Imagine scooping out most of the fluffy interior, leaving a bit, and adding cheese for quick, homemade potato skins!
Expert Tip: For optimal cooking, my personal favorites are the Cosori models or creating Ninja Foodi recipes, especially those with an attached lid for seamless transitions between functions.
Achieving perfectly crispy air-fried foods begins with preheating. It’s considered best practice to always place your ingredients into a hot basket. Learn how to properly preheat your air fryer to ensure maximum crispiness and even cooking.

When I first started sharing my enthusiasm for my new Cosori air fryer, many people expressed interest but lamented their lack of kitchen space. This is precisely why multi-cooker machines are such a game-changer! They combine various functions into one compact unit, making them an excellent choice for anyone seeking versatility without clutter. Simply twist the function knob to select your desired cooking method, then set the time and temperature, and press start. It’s incredibly straightforward, and making mashed potatoes was one of the first things I tried!

Whether you prefer the hearty flavor of Russet potatoes or the creamy texture of sweet potato mash, the following steps will guide you to perfection. The primary difference between the two potato types will be their size, which might slightly adjust cooking times, but the method remains largely the same.
Can You Cook Raw Potatoes in an Air Fryer?
Absolutely! The air fryer is excellent for cooking raw potatoes, both whole and diced. Simply follow the instructions outlined in our recipe. Begin by lightly spraying the air fryer basket to prevent sticking. Add your washed and dried potatoes, then spray them generously with olive oil. This not only aids in cooking but also helps achieve a beautiful golden exterior. Now is also the perfect time to add any desired seasonings. This method is precisely how we achieve perfectly cooked air fryer sweet potato cubes, which you can see in some of our other recipes.
Making Mashed Potatoes from Air-Fried Baked Potatoes
Yes, this is the core technique we’re using for this recipe! We start by air frying whole potatoes until they are tender and fluffy inside, essentially creating perfect baked potatoes. From there, we simply scoop out the soft centers to transform them into a creamy, flavorful mashed side dish. This process is surprisingly quick, typically taking around 45-50 minutes total to achieve beautifully cooked potatoes ready for mashing.
Ingredient Notes for Perfect Air Fryer Mashed Potatoes
Let’s dive into the essential ingredients that will elevate your air fryer mashed potatoes to new heights:
- Potatoes: You’ll need about four large potatoes. While sweet potatoes are featured in some of our visuals, Russet potatoes are an excellent choice for a more traditional, savory mashed potato. Choose firm, blemish-free potatoes.
- Olive Oil Spray: A generous amount of olive oil spray is crucial for coating the outside of your potatoes. This prevents them from burning and helps create a lovely crispy skin. Even if you plan to discard the skins for mashing, the oil contributes to the overall cooking process and flavor. If you’re peeling the skins off later, you can use slightly less. The crispy skins can even be repurposed to make delicious potato skins later.
- Butter: For that rich, creamy texture and unbeatable flavor, butter is non-negotiable. I personally adore creamy, salted Kerrygold butter for its superior taste, but any good quality butter will work wonders. Ensure it’s softened for easier blending.
- Milk or Sour Cream: To achieve the desired creamy consistency, you’ll need to add a liquid. Milk (2% or whole milk works best) is a classic choice, allowing you to adjust the thickness to your preference. For an extra tang and richness, sour cream is a fantastic alternative, especially for savory mashed potatoes. You can even combine both!
- Seasonings: This is where you truly personalize your mash.
- For sweet potato mash, consider a sprinkle of cinnamon and a touch of brown sugar or maple syrup for an autumnal warmth.
- For savory mashed potatoes, garlic salt, onion powder, a dash of black pepper, and fresh chives or chopped green onions are excellent additions.

Expert Tips for Cooking Potatoes to Make Mashed Potatoes
Whether you’re making Air fryer baked potatoes or a batch of Sweet potatoes in the air fryer specifically for mashing, a few key tips will ensure perfect results every time:
- To Oil or Not to Oil (for peeling): If your sole purpose is to peel the skins off and not use them for anything else, you don’t necessarily need to coat the potatoes as liberally with olive oil. However, a light coating still helps with even cooking and prevents the potato flesh from drying out.
- Fork-Tender Perfection: The goal is fork-tender potatoes. You’ll know they’re ready when a knife or fork slides into the middle of the largest potato very easily with no resistance. Overcooking can make them mushy, while undercooking results in lumpy mash.
- Cooling Time: Once cooked, allow the potatoes to cool just enough so you can comfortably handle them. This prevents burns and makes the scooping process much easier.
- Scoop and Mash: Carefully slice each potato lengthwise, scoop out the fluffy insides into a large mixing bowl, discarding the skins (or saving them for potato skins!).
- Add-Ins and Mixing: Now’s the time to incorporate all your delicious add-ins: softened butter, milk or sour cream, and your chosen seasonings.
- Don’t Overmix! This is perhaps the most crucial tip for fluffy mashed potatoes. The more you mix or beat potatoes, the more starch is released, leading to a gummy or gluey texture. Use an electric mixer on low speed or a potato masher, mixing just enough to combine everything until smooth and creamy.
- Serve Immediately: For the absolute best texture and flavor, enjoy your air fryer mashed potatoes immediately after preparing them.


Air Fryer Mashed Potatoes Recipe
Equipment
- 1 air fryer
Ingredients
- 4 large potatoes, sweet or russet, washed and dried
- 3 tbsp olive oil
- 1/2 cup butter, softened
- 1/2 cup milk, 2% or whole (may want more to thin out)
Instructions
- Clean potatoes thoroughly and dry them completely. Prick each potato several times around its surface with a fork.
- Generously rub the outside skins of each potato with olive oil. You can sprinkle salt on the outsides at this time if desired for added flavor, or leave them plain depending on your preference.
- Place the prepared potatoes onto the air fryer rack or into the basket. Set your air fryer to 400°F (200°C) and cook for approximately 45-50 minutes. Remember to flip each potato halfway through the cooking time to ensure even crisping and cooking.
- Remove the potatoes when their insides are tender. Test for doneness by inserting a knife into the middle of the largest potato; it should slide in very easily. Allow them to cool enough so you can handle them comfortably.
- Once cool enough, carefully remove the outside skins (if not making potato skins) and scoop the fluffy insides into a large mixing bowl.
- Add the softened butter to the bowl. Using an electric mixer on low speed or a potato masher, beat or mash to combine well. Slowly add the milk (and any other seasonings you’d like, such as garlic salt for savory or cinnamon for sweet) until the potatoes reach your desired creamy consistency. Be careful not to overmix, as this can make the potatoes gummy.
- For sweet potato mash, it’s particularly delicious with a little cinnamon and/or maple syrup added during the mashing process.

Leftover mashed potatoes are incredibly versatile! You can easily transform them into delicious potato cakes. Simply form them into patties and place them in the air fryer at 370°F (188°C) for about 6 minutes, or until they’re beautifully crispy and golden brown on the outside. These make a fantastic breakfast or side dish! Of course, you can also just reheat them gently in a pan on low heat or in the microwave and serve them with a hearty steak or any main course the next day.
To elevate the flavor of your air fryer mashed potatoes, consider these delightful additions:
