Working with one piece of cheese at a time, dredge each piece of string cheese in flour mixture, shake off excess. Dip in egg mixture, then coat in breadcrumb mixture and press to ensure it sticks.
Repeat this process again for each stick, then transfer to prepared baking sheet.
Transfer baking sheet to freezer and let freeze for at least 1 hour.
Fill a large pot with about 2" oil over medium heat until a thermometer inserted in the oil reaches 350°F.
Working in batches of no more than 4, carefully drop sticks into hot oil and turn occasionally until they are golden brown and crisp (about 2 minutes).
Transfer to a paper towel-lined plate, and sprinkle with a little salt if desired.
Serve immediately with your favorite dipping sauce (try my small batch marinara sauce recipe below) and enjoy!
