1. Start by ensuring your mashed potatoes are chilled and firm. If you’re using leftover mashed potatoes, make sure they have cooled completely in the refrigerator. If you’re making fresh mashed potatoes, allow them to cool to room temperature before proceeding.

2. In a large mixing bowl, combine the chilled mashed potatoes, shredded mozzarella or cheddar cheese, grated Parmesan cheese, beaten egg, garlic powder, onion powder, salt, and pepper. Mix everything together until the ingredients are well incorporated and the mixture is cohesive.

3. Take about 2 tablespoon of the potato mixture and gently roll it into a ball between your palms. Repeat this process with the remaining mixture to form 12-14 evenly sized potato balls.

4. Place the breadcrumbs in a shallow bowl or plate. Roll each potato ball in the breadcrumbs, ensuring they are fully coated. This will give the Air Fryer Cheesy Mashed Potato Balls their delightful crunchy exterior when cooked.

5. Preheat your air fryer to 375°F. Lightly spray the air fryer basket with cooking spray or drizzle a little olive oil. Carefully place the breaded potato balls in the basket, making sure they are not touching each other. Lightly spray or drizzle the tops of the balls with a bit more cooking spray or olive oil. Air fry for 10-12 minutes, shaking the basket halfway through, until the potato balls are golden brown and crispy.

6. Once the Air Fryer Cheesy Mashed Potato Balls are cooked, remove them from the air fryer and let them cool slightly before serving. These irresistible bites can be enjoyed as a snack, appetizer, or side dish. Savor the perfect balance of crispy exterior and melted, cheesy interior in every delectable mouthful.
