You know those mornings after a big holiday dinner? The fridge is packed, and there’s always, always a giant bowl of leftover mashed potatoes staring back at you. For years, I’d just reheat them, maybe make a shepherd's pie, but honestly, I was craving something new, something with a bit of a crunch! One chaotic Sunday, with a mountain of cold mashed potatoes, I thought, “What if I just... rolled them up and put them in the air fryer?” I didn’t expect that little experiment to become such a hit, but oops, it did! The kitchen was a bit of a mess, flour everywhere, but the smell of cheesy potatoes crisping up? Pure magic, I tell ya.
My very first batch of Air Fryer Cheesy Mashed Potato Balls was... interesting. I forgot to spray them with oil, and they came out looking a little pale and sad, not the golden beauties I envisioned. And one or two might have crumbled a bit when I tried to flip them too early, total kitchen disaster moment! But even with the imperfections, the taste was there. It was that comforting, cheesy goodness, reimagined. It just goes to show, sometimes the best recipes come from trying something new and learning from your little kitchen oopsies.
Ingredients for Air Fryer Cheesy Mashed Potato Balls
Base Ingredients
- Leftover Mashed Potatoes: Honestly, this is where the magic starts. Cold, day-old mashed potatoes are key they hold their shape so much better than fresh, warm ones. Don't even think about using runny, soupy mashed potatoes, I tried that once, and it was a disaster, just a cheesy, potato-y puddle in the air fryer basket!
- Shredded cheese: Oh, the cheese! I usually go for a sharp cheddar or a melty mozzarella, or a mix of both. The sharper cheese adds so much flavor, and the mozzarella gives you that epic cheese pull. To be real, use whatever melty cheese you have on hand, but avoid pre-shredded if you can it often has anti-caking agents that make it melt a little weird.
- Large Egg: This is our binder, our glue! One large egg helps hold those beautiful potato balls together. I didn't expect that one egg could make such a difference, but trust me, it's essential for keeping them from crumbling into a million little pieces.
- All-Purpose Flour: Just a little bit of flour, maybe a few tablespoons, helps firm up the mixture and gives the outside a slight crisp. I've tried it without, and they were a bit too soft, a bit too fragile, almost like they wanted to collapse under pressure, bless their hearts. If you're gluten-free, a 1:1 gluten-free flour blend works great here, I've done it!
Flavor Boosters & Seasonings
- Garlic Powder & onion Powder: Flavor boosters, plain and simple. These two are my secret weapons for adding that savory depth without having to sauté fresh garlic and onion. Honestly, I'm a bit heavy-handed with these, you can add more if you're like me and believe garlic makes everything better. No judgment here!
- Dried Chives: Adds a lovely pop of color and a mild oniony freshness. I always have a jar of dried chives in my pantry, they're just so convenient. Fresh chives work too, of course, if you're feeling fancy, but the dried ones are perfectly fine for this kind of comfort food.
- Salt & Black Pepper: Seasoning is everything, right? Taste your mashed potatoes first! If they're already well-seasoned, you might need less. I always add a generous pinch of flaky sea salt at the end too, it just elevates the whole thing, makes those flavors sing.
For Frying & Finishing
- Olive Oil Spray: This is crucial for getting that golden, crispy exterior without deep-frying. A light mist is all you need. I forgot to spray them once, and they looked a bit pale and sad, not the vibrant golden-brown I was aiming for. Learn from my oops!
- Fresh Parsley (for garnish): Totally optional, but a little sprinkle of fresh parsley at the end just makes them look extra pretty and adds a touch of freshness. It's that little something extra that makes you feel like you put in more effort than you actually did, ha!
Instructions to Make Air Fryer Cheesy Mashed Potato Balls
- Step 1: Prep the Potatoes
- First things first, grab those leftover mashed potatoes. They need to be cold, honestly, it's a non-negotiable for these Air Fryer Cheesy Mashed Potato Balls. Scoop them into a big mixing bowl. If they're a bit lumpy, that's okay, adds character! I usually give them a quick mash with a fork just to make sure they're uniform enough, but not overmixed, we don't want gummy potatoes, yuck!
- Step 2: Mixing in the Good Stuff
- Now, let's get everything else in there. Add your shredded cheese, that one egg, the all-purpose flour, garlic powder, onion powder, and dried chives to the bowl with your mashed potatoes. Season with salt and pepper, remembering to taste your potatoes first. Gently mix everything together with a spoon or your hands (my preferred, messier method!). Don't overmix, just combine until everything is evenly distributed. You're looking for a mixture that holds its shape, not too sticky, not too dry.
- Step 3: Forming the Air Fryer Cheesy Mashed Potato Balls
- Time to get your hands a little dirty! Scoop about 1.5 to 2 tablespoons of the potato mixture and roll it into a ball, roughly the size of a golf ball. I usually have a small bowl of water nearby to dampen my hands a little, it helps prevent the mixture from sticking. Place the formed potato balls on a plate or baking sheet. This is where I sometimes get distracted and make some balls bigger than others, but hey, homemade charm, right?
- Step 4: Preheating the Air Fryer
- While you're rolling, go ahead and preheat your air fryer to 375°F (190°C). This step is important, don't skip it! A preheated air fryer ensures those Air Fryer Cheesy Mashed Potato Balls start crisping up immediately, giving you that beautiful golden crust. I once threw them into a cold air fryer, and they took forever to cook and weren't nearly as crispy. Live and learn!
- Step 5: Air Frying the First Batch
- Once the air fryer is preheated, lightly spray the basket with olive oil spray. Arrange a single layer of your potato balls in the basket, making sure not to overcrowd them. Give the potato balls themselves a light spray of olive oil too this is key for that golden color and crispy texture. Air fry for 10-12 minutes, flipping them halfway through. You'll see them transform, turning golden brown and smelling absolutely amazing!
- Step 6: Finishing and Serving Your Air Fryer Cheesy Mashed Potato Balls
- Remove the first batch of golden, crispy Air Fryer Cheesy Mashed Potato Balls from the air fryer and repeat with any remaining mixture. Serve them immediately, sprinkled with a little fresh parsley or a dash of flaky sea salt. The outside will be wonderfully crisp, and the inside will be warm, fluffy, and oh-so-cheesy. Honestly, they're hard to resist straight out of the fryer, so be warned!
I remember one chaotic Tuesday evening, trying to whip these Air Fryer Cheesy Mashed Potato Balls up after a long day. My kitchen was a disaster zone, flour on the counter, potato bits on the floor, but then that smell... that cheesy, garlicky aroma filling the air. It just melted away the day's stress. Watching those little balls puff up and turn golden in the air fryer, it felt like a small victory. Sometimes, the simplest things bring the most joy, even if it involves a little mess.
Air Fryer Cheesy Mashed Potato Balls: Storage Tips
Okay, so these Air Fryer Cheesy Mashed Potato Balls are definitely best enjoyed fresh, hot out of the air fryer. The crispiness, honestly, is what makes them sing! If you do have leftovers (which, let's be real, is rare in my house), store them in an airtight container in the fridge for up to 3 days. Reheating them in the air fryer at 350°F (175°C) for 5-7 minutes will bring back some of that crispness, but they won't be quite as crunchy as fresh. I microwaved them once, and they got a bit soft and sad, so don't do that lol. For meal prep, you can form the balls ahead of time and keep them covered in the fridge for a day, then air fry when ready.

Air Fryer Cheesy Mashed Potato Balls: Ingredient Substitutions
Life happens, and sometimes you just don't have everything on hand, right? For the cheese, I've tried a sharp white cheddar, a mild Colby Jack, even a smoked gouda once that was interesting, kinda. Any good melting cheese will work, but definitely avoid those crumbly, dry cheeses. If you're out of chives, a tiny pinch of dried parsley or even a sprinkle of finely chopped green onion works for that pop of color. For the flour, a 1:1 gluten-free baking blend is a solid swap. I even experimented with breadcrumbs instead of flour once, and they came out super crispy, almost like a croquette, which was a happy accident!

Frequently Asked Questions About Air Fryer Cheesy Mashed Potato Balls
- → Can I use fresh mashed potatoes?
You can, but honestly, it's a bit trickier! Fresh mashed potatoes tend to be warmer and softer, making them harder to roll. If you do, make sure they've cooled completely, maybe even chill them in the fridge for an hour. I've tried it, and they were a bit stickier, definitely more of an 'oops' moment than using cold leftovers.
- → What kind of cheese works best for these Air Fryer Cheesy Mashed Potato Balls?
I'm a big fan of sharp cheddar or a mozzarella-cheddar blend for these. The key is a good melting cheese. Stay away from crumbly cheeses like feta. I once used a hard Parmesan, and it just didn't melt nicely inside, which was a bit disappointing, to be real.
- → My potato balls are falling apart in the air fryer, what happened?
Oh, I've been there! Usually, it means your mixture wasn't quite firm enough, or you might have skipped the egg binder. Make sure your mashed potatoes are cold and not too wet. Sometimes, adding an extra tablespoon of flour can help firm things up. Don't worry, it's a common kitchen mishap!
- → How do I store and reheat these Air Fryer Cheesy Mashed Potato Balls?
Leftovers can go in an airtight container in the fridge for up to 3 days. To reheat, pop them back into the air fryer at 350°F (175°C) for about 5-7 minutes. It gets them nice and crispy again. I wouldn't recommend the microwave, honestly, they just get soggy and lose their charm.
- → Can I add other ingredients to the potato mixture?
Absolutely, that's the fun part! I've sometimes added finely chopped bacon bits, a sprinkle of smoked paprika, or even some finely diced jalapeños for a kick. Just don't go too crazy with wet ingredients, or your potato balls might get too soft to roll. Experiment and see what you love!
