Add the chopped potatoes to a pot of water and bring it up to a boil. Turn down the heat and cook until soft.
Take off heat, drain and transfer the potatoes to a large bowl. Allow them to cool down completely, then mash using a potato masher.
Add crushed Doritos, garlic powder, onion powder, chopped parsley, salt, pepper, red pepper flakes and cornstarch.
Mix well until the spices are uniformly incorporated into the mixture.
Grease your hands with a bit of oil. Portion and roll the mixture into small balls.
Do this until all of the mixture is rolled.
Transfer to a lined Air Fryer basket and spray some cooking oil over the balls. Air fry at 380°F for 10-15 minutes, shaking the basket a couple of times during the cooking time to get the mashed potato balls golden brown on all sides.
Notes
Use starchy potatoes like Russets for a fluffy texture, and drain them thoroughly after boiling to prevent the mixture from becoming too wet.
Let the potatoes cool completely before mashing and shaping, as warm mashed potatoes may be too soft to hold their shape.
Crush the Doritos into fine crumbs so they mix evenly into the potatoes without creating large pieces.
If the mixture feels too soft or sticky, refrigerate it briefly before rolling into balls.
Lightly grease your hands with oil to make shaping easier, and keep the balls similar in size for even cooking.
Arrange the potato balls in a single layer in the air fryer basket, leaving space between them for proper air circulation.
Air fry at 380°F (193°C) for 10–15 minutes, shaking gently once the outsides have firmed up.
Swap the Doritos for another flavored tortilla chip, or reduce the red pepper flakes for a milder version.
Serve immediately with your favorite creamy dipping sauce for the best crispy texture.
Refrigerate leftovers in an airtight container within 2 hours and use within 3 days. Reheat in the air fryer until hot and crispy.
