Combine mashed potato, egg yolk, onion, salt, pepper, garlic powder, cheese, sour cream in a large bowl. Roll heaped tablespoons of mixture into golf size balls.
Place flour on a plate. Place breadcrumbs on another plate. Whisk egg and milk together in a shallow bowl. Roll croquettes in flour, shaking off excess. Dip in egg mixture then coat in breadcrumbs.
Heat oil in a deep frying pan over medium-high heat. Cook croquettes, in batches, turning, for 3 to 4 minutes or until golden. Transfer to a plate lined with paper towel. Serve with choice of your dipping sauce.
