Garlic Butter: In a small bowl add butter, parsley and garlic. Mash with a fork until evenly combined. Use a 1 tsp measuring spoon and scoop out the butter into 1 tsp portions on a sheet of parchment paper. You should get around 20 balls of butter. Place in the freezer for 30-60mins, or until nice and firm.
Meatballs: Meanwhile in a large mixing bowl add chicken, 3/4cup breadcrumbs, parmesan, egg, onion and salt & pepper. Use your hand to combine until everything is evenly distributed, then use a 1 tbsp measuring spoon to scoop out chunks of meat. You should get around 20 chunks. Place a piece of garlic butter in the centre of the chunks of meat then roll into meatballs, ensuring the butter is contained.
Coat: Line up 3 bowls - the first is flour with a pinch of salt and pepper, the second is 2 beaten eggs and the third is breadcrumbs with a pinch of salt and pepper. One by one coat the meatball in flour, then egg and finish in a good coating of breadcrumbs. Repeat with remaining meatballs.
Fry: Heat up enough oil to comfortably cover the size of a kiev in a suitably sized pot. You want to temp to get to 175C/350F. Once you've reached that temp carefully lower in 5-6 kievs and fry for 4-5mins, or until deep golden and crispy. Place on wire rack with paper towels underneath to catch excess oil. Repeat with the other batches.
Serve: Allow to cool for a few mins before tucking in as the butter is likely to be very hot. Serve up as finger food with a dip or with fries to make a meal!
