For the Coating:

1. 1. Set up three shallow bowls: one with flour, one with whisked eggs, and one with breadcrumbs mixed with Italian seasoning.
2. 2. Roll each string cheese stick in flour until fully coated. Shake off excess flour. Dip into the egg mixture, then roll in breadcrumbs until completely covered.

For Freezing and Frying:

1. 3. Place the breaded cheese sticks on a parchment-lined baking sheet and freeze for about 30 minutes to prevent oozing during cooking.
2. 4. In a deep frying pan or pot, heat oil over medium-high heat to approximately 350°F (175°C).
3. 5. Carefully add frozen cheese sticks to the hot oil in batches, frying until golden brown and crispy (about two minutes per side).
4. 6. Transfer fried mozzarella sticks onto paper towels to drain excess oil and serve hot with marinara sauce for dipping.
