In a shallow dish, beat the eggs with a fork until well blended and set aside. Add the flour to large freezer bag or bowl, and set that aside too.
Pour your Panko breadcrumbs into another shallow dish and drizzle on the olive oil. Toss until the crumbs are well coated. Add the garlic powder, salt, and parmesan cheese to the Panko crumbs and whisk until well combined.
Add the string cheese to the bag with the flour and shake around until they're completely coated.
Working with 2-3 sticks at a time, remove them from the flour mixture, and shake off any excess flour back into the bag.
Add the sticks to the egg mixture and roll around until completely coated in the beaten egg.
Next, transfer the sticks to the Panko mixture. Roll and press the sticks in the breadcrumbs to get them as evenly coated as possible.
Add the breaded cheese sticks back to the egg mixture. Roll to coat all sides well and coat any spots that may have been missed the first time.
Then roll them again in the Panko breadcrumbs, making sure that absolutely no cheese is visible. Take the time to really mold and pack the breading around the cheese stick!
Place breaded cheese sticks in a single layer on a sheet pan or in a baking dish sprayed with cooking spray. Repeat the above process until all the sticks are completely double breaded.
Once all the string cheese has been breaded, move the baking dish or sheet pan to the freezer and freeze the sticks for at least an hour until the breading is firm.
