Start by cutting your mozzarella block into uniform sticks. Aim for a size that’s easy to handle, around the length of your finger. If you’re using string cheese, you’re good to skip this step.
Next, prepare three shallow bowls for your dredging process. Fill one with flour, the second with whisked eggs, and the third with your crushed panko crumbs mixed with Italian seasoning, parsley, garlic powder, black pepper, and salt. Make sure everything is within reach for assembly.
One by one, take each piece of mozzarella and coat it in flour, ensuring all sides are covered. Shake off any excess, then dip it into the egg mixture. Finally, roll it in the seasoned panko crumbs, pressing gently to ensure the crumbs stick. Repeat this process for double coating, which helps create a thicker barrier that keeps the cheese intact during frying.
Once all your mozzarella sticks are breaded, place them on a cooling rack set over a baking sheet. Pop this setup into the freezer for at least one hour. Freezing is crucial to prevent the cheese from oozing out during frying.
Heat your vegetable oil in a medium saucepan over medium heat, using a thermometer to monitor the temperature. Bring the oil to 350°F (175°C). Fry two sticks at a time for about one minute, or until they turn golden brown and crispy. Remove and place them on a paper towel-lined plate to drain excess oil. Repeat until all sticks are fried.
