Place the cheese cubes on a tray and chill in the fridge for about 10 minutes to help them stay firm during coating.
Set up your breading station: put flour in a shallow bowl, beaten eggs in another, and panko breadcrumbs mixed with smoked paprika in a third.
Roll each cheese cube in the flour, tapping off any excess to ensure an even coating.
Dip the floured cheese cube into the beaten eggs, allowing any excess to drip off.
Roll the egg-coated cheese in the seasoned panko breadcrumbs, pressing gently to help the coating stick evenly.
Place the coated cheese balls on a tray and chill again for about 10 minutes. This helps the coating set and prevents leakage during frying.
Heat the oil in a deep pot to 180°C (350°F). Use a thermometer to monitor the temperature for a consistent fry.
Carefully add the cheese balls in batches to the hot oil, frying for about 2-3 minutes until they are golden brown and crispy, turning gently with a slotted spoon.
Use a slotted spoon to remove the fried cheese balls and drain on paper towels, repeating until all are cooked.
Let the cheese balls rest for a minute or two to settle the molten cheese, then sprinkle with chopped parsley if desired. Serve immediately for best crunch and gooeyness.
