Cut string cheese sticks in half, then place in the freezer for 15 minutes to an hour.
Prep for the breading process. Get 3 bowls out. Place flour in one bowl. Whisk eggs in another bowl. Then combine the panko and bread crumbs in the third bowl.
Preheat oven to 350 and prepare a baking sheet with a light coating of cooking spray.
Remove cheese sticks from freezer and dredge in flour. Coat with egg, then dip in bread crumb mix to coat. If you'd like a thicker breading repeat the egg and bread crumb mix steps. Place coated cheese sticks on baking sheet.
Bake cheese sticks for approximately 10 minutes, checking sticks halfway through to make sure the cheese isn't melting too much.
