In a large bowl, combine the flour, granulated garlic, salt and pepper.
Add in the chicken pieces and stir to coat well. I prefer to use my hands for this, ensuring that each and every piece is coated evenly in the mixture.
In a medium bowl, whisk together the egg and milk.
In another medium bowl, stir together the breadcrumbs and salt and pepper to taste.
Heat a few inches of oil to 350 F in a deep fryer or Dutch oven. While the oil is heating you can prepare the nuggets for frying.
Working in batches, remove the chicken pieces from the flour mixture and shake off an excess.
Transfer the chicken to the bowl containing the egg mixture. Turn the pieces to coat well.
Shake off any excess and transfer the chicken pieces to the bowl containing the breadcrumbs.
Turn the pieces to coat well. Get all sides.
Fry chicken pieces 2-3 minutes per side, turning once. Remove to a paper towel-lined plate or wire rack-lined baking sheet to drain.
Serve with your favorite dipping sauce.
Notes
These nuggets can be frozen and reheated at a later time. I put the frozen nuggets into an air fryer at 365 F for 10 minutes to reheat them.
