Place mashed potatoes in a mixing bowl. Add cheddar cheese, green onions, butter, garlic powder, onion powder, salt, pepper, and parsley. Mix until well combined.

Add the egg and flour to the mixture and stir until it forms a thick dough-like consistency.

Refrigerate the mixture for about 20 to 30 minutes to help it firm up.

Scoop about 1 tablespoon of the chilled mixture and roll it into small balls. Place them on a tray.

Roll each ball lightly in flour, dip into beaten egg, then coat with breadcrumbs.

Heat vegetable oil in a deep pan to about 350°F (175°C).

Fry the potato bites in small batches for 2 to 3 minutes until golden and crispy.

Remove and place on paper towels to drain excess oil, then serve warm with your favorite dipping sauce.
