How to Make Leftover Air Fryer Mashed Potato Balls
-
Prep the mashed potatoes
Start with cold mashed potatoes straight from the fridge so the mixture shapes cleanly and holds together.
If your potatoes seem very loose, stir in an extra spoonful of breadcrumbs until they feel scoopable.
-
Mix the potato filling
In a large bowl, combine the cold mashed potatoes, cheddar, Parmesan, green onions, garlic powder, onion powder, salt, and pepper.
Pour in the beaten egg and gently mix until everything is evenly combined and sticky but not wet.
-
Shape the potato balls
Line a small baking sheet or plate with parchment so the potato balls do not stick as they rest.
Scoop tablespoon-size portions of the mixture and roll between your palms into firm balls, packing gently as you go.
-
Coat with breadcrumbs
Pour the breadcrumbs into a shallow bowl or plate to create an even coating surface.
Roll each potato ball in the breadcrumbs until fully covered, pressing lightly so the crumbs adhere to the outside.
-
Air fry until crisp and golden
Preheat your air fryer to 375°F for about 5 minutes so the basket is hot before you add anything.
Arrange the coated potato balls in a single layer in the basket, leaving a little space between each one.
Spray the tops lightly with olive oil, then air fry for 10 to 12 minutes, turning once halfway through.
The potato balls are ready when they are deep golden, crisp on the outside, and hot and melty inside.
-
Stir together the garlic aioli
While the potato balls cook, stir together the mayonnaise, garlic, lemon juice, Dijon, salt, and pepper in a small bowl.
Taste and adjust the seasoning with a little extra lemon, salt, or pepper until it suits your liking.
-
Serve with garlic aioli
Transfer the hot potato balls to a serving plate and let them cool for just a minute before biting in.
Serve with the garlic aioli on the side for dipping and enjoy them while they are still crisp.
Substitutions
- Breadcrumbs -> gluten-free breadcrumbs or finely crushed rice crackers
- Use gluten-free breadcrumbs or plain crushed rice crackers for a similar crunch without the wheat, keeping the texture light and crispy.
- White cheddar cheese -> mozzarella or pepper jack
- Mozzarella gives a milder, stretchier cheese pull, while pepper jack adds a gentle kick and more personality without changing the texture much.
- Breadcrumb coating -> crushed salted potato chips
- Crushed potato chips make the outside extra crunchy and intensely potato flavored, with a fun party-snack vibe everyone notices.
Tips
- Start with firm, cold mash
- Very creamy potatoes can make loose balls that collapse. Chill them well and add a spoon of breadcrumbs if needed.
- Chill shaped balls for extra stability
- If you have time, chill the shaped balls for 20 minutes before coating and air frying to help them keep their shape.
- Avoid overcrowding the air-fryer basket
- Cook in batches if needed so hot air can circulate. Crowded baskets give pale, soft spots instead of even crisping.
- Use oil spray the right way
- Hold the spray a little away from the balls so you mist them lightly. Heavy spraying can make the coating soggy in spots.
- Season to match your leftovers
- Taste your mashed potatoes first. If they were already very salty or garlicky, reduce the added salt or garlic powder a bit.

FAQ
- My potato balls keep falling apart in the air fryer. What am I doing wrong?
- The mixture is likely too soft or warm. Stir in more breadcrumbs, chill the shaped balls, and handle them gently with a spatula.
- The centers are still cold when the outside is browned. How can I fix this?
- Lower the temperature to about 350°F and cook a little longer. Smaller balls also warm through more easily without overbrowning.
- Can I bake these instead of air frying them?
- Yes, bake on a parchment-lined sheet at 400°F for 15 to 20 minutes, turning once, until golden and fully heated.
- Can I make these leftover mashed potato balls ahead of time?
- You can shape and bread them, then refrigerate for up to one day. Air fry straight from the fridge, adding a couple minutes if needed.
- How do I reheat leftover potato balls so they stay crisp?
- Reheat them in the air fryer at 350°F for 4 to 6 minutes. Avoid the microwave, which makes the coating soft and chewy.
Serving Suggestions
These crispy mashed potato balls are especially good with a squeeze of extra lemon over the warm garlic aioli.
Pair them with tomato soup, grilled chicken, or a big salad for a comforting but easy dinner spread.
