Whisk the eggs and water together in a small bowl. Set this next to the bowl of flour.
Mix the panko, bread crumbs, Italian seasoning, salt, garlic powder, and pepper in another small bowl and set this next to the bowl with the beaten eggs.
Prepare a tray lined with parchment paper and set this next to the bowl with the bread crumb mixture.
Use tongs to place each mozzarella stick into the flour mixture (cover completely), then dip it into the egg mixture, then completely cover it with the bread crumb mixture and set it onto the prepared tray.
When all of the mozzarella sticks have had one coat of breading we are going to give them a second coating. This time, flour is not needed. So again using the tongs, place each bread stick in the egg mixture and then coat completely with the bread crumb mixture (sides and ends as well). Again place these on the tray.
Freeze the coated mozzarella sticks for at least 1 hour.
Heat the oil in a heavy skillet, or dutch oven, to a temperature of 325-350 degrees. (just pay attention to how quickly they are browning and adjust your temperature)
Place a place lined with paper towels next to the deep frying station.
Fry mozzarella sticks for a minute or 2 per side, or until golden brown. Do not crowd the pan as it will drop the temperature of the oil.
Remove mozzarella sticks to the plate lined with paper towels.
Serve with marinara sauce on the side if you like.
Notes
These can be made in the air fryer, see the FAQ section above.
Try different string cheese flavors to switch it up!
You will want to double coat these to ensure that the cheese does not seep out.
