This crispy, cheesy air fryer potato creation transforms leftover mashed potatoes into irresistible golden bites that disappear in minutes at my dinner table. The contrast between the crunchy exterior and the gooey cheese center makes these little treasures absolutely addictive.
I first created these during a busy holiday weekend when facing a mountain of leftover mashed potatoes. My family now intentionally asks me to make extra mashed potatoes just so we can enjoy these crispy treats the next day.
Ingredients
- 2 cups chilled mashed potatoes: provides the perfect base and must be cold for proper shaping
- 1 cup shredded mozzarella or cheddar cheese: creates that irresistible stretchy texture when melted
- ½ cup grated Parmesan cheese: adds depth and savory notes to every bite
- 1 beaten egg: works as the essential binding agent for structure
- ½ teaspoon garlic powder: infuses subtle aromatic flavor throughout
- ½ teaspoon onion powder: complements the garlic with sweet savory notes
- Salt and pepper to taste: lets you control the seasoning level
- 1 cup breadcrumbs: creates that essential crispy exterior shell
- Cooking spray: ensures even browning without excess oil
Step-by-Step Instructions
- Prepare the Potato Mixture:
- Combine mashed potatoes, shredded cheese, Parmesan, garlic powder, onion powder, salt, and pepper in a large mixing bowl until thoroughly incorporated. The cold potatoes will help the cheese stay in pieces rather than melting into the mixture, creating pockets of gooeyness when cooked.
- Shape the Balls:
- Form the potato mixture into 1.5-inch balls using your hands or a cookie scoop for consistency. If you find the mixture sticking excessively to your hands, refrigerate it for 10-15 minutes to firm up further. Slightly damp hands can also help prevent sticking during this process.
- Coat the Balls:
- Create a dredging station with beaten egg in one bowl and breadcrumbs in another. Dip each potato ball completely in egg, allowing excess to drip off, then roll thoroughly in breadcrumbs, pressing gently to ensure complete and even coating around the entire surface.
- Preheat and Arrange:
- Preheat your air fryer to 375°F for optimal crispiness. Lightly spray the basket with cooking spray to prevent sticking. Place potato balls in a single layer with space between each to allow proper air circulation for even cooking and maximum crispness on all sides.
- Cook the Balls:
- Air fry for 10-12 minutes total, pausing halfway through to shake the basket gently for even browning. Look for a deep golden color and crisp exterior. The interior will be hot and the cheese will be perfectly melted when done.
- Serve and Enjoy:
- Transfer immediately to a serving dish and enjoy while hot and at their crispiest. Serve alongside dipping sauces like ranch dressing, marinara sauce, or sour cream for added flavor dimensions.

These potato balls remind me of my grandmother's croquettes, though she would spend hours standing over hot oil. The air fryer gives me the same comforting taste with less mess and more time to actually enjoy with my family rather than monitoring a pot of hot oil.
Make Ahead Options
These potato balls can be prepped up to the breading stage and refrigerated for up to 24 hours before cooking. Simply place them on a parchment-lined tray, cover loosely with plastic wrap, and refrigerate. When ready to cook, bring them to room temperature for about 15 minutes before air frying for best results. This makes them perfect for party preparation when you want to minimize last-minute work.
Flavor Variations
Transform this basic recipe by experimenting with different fillings and seasonings. Try placing a small cube of cheese in the center for an extra gooey surprise, or mix in cooked bacon bits, chives, or jalapeños for added flavor dimensions. For an Italian twist, incorporate some Italian herbs and serve with marinara. For a loaded potato version, add in sour cream, bacon bits, and green onions to the potato mixture.

Perfect Pairings
These versatile bites complement many meals but shine especially alongside grilled meats or as part of a game day spread. Serve them with a crisp green salad for a light lunch, or alongside a creamy soup for a satisfying dinner. For an elegant appetizer presentation, place them on a platter with small bowls of various dipping sauces and garnish with fresh herbs.
Storage and Reheating
Store any leftover potato balls in an airtight container in the refrigerator for up to 3 days. To reheat, place them back in the air fryer at 350°F for 3-4 minutes until heated through and crispy again. While microwaving is possible, it will sacrifice the crispy texture. These can also be frozen after cooking for up to 1 month simply reheat from frozen in the air fryer for about 6-8 minutes.
