Preheat the oven to 400°F (200°C).

In a mixing bowl, combine the mashed potatoes, cheddar cheese, beaten egg, garlic powder, onion powder, dried parsley, salt, and pepper.

Mix until well combined.

Form the mixture into small bite-sized balls.

Roll each ball in breadcrumbs to coat.

Place the coated potato bites on a baking sheet lined with parchment paper.

Bake in the preheated oven for 20-25 minutes or until golden brown and crispy.
