Prepare 3 bowls (or I use bread pans), one with flour, one with eggs (beaten together), and one for the bread crumbs which we'll first fry in the next step.
Heat oil in a skillet over medium heat. Oil is hot enough when a drop of water is added to the pan and immediately sizzles. Add bread crumbs and stir continuously for 3-4 minutes or until a dark golden brown. Transfer bread crumbs to the bread pan.
Unwrap each mozzarella string cheese stick. Using a fork, thoroughly coat the first cheese stick in flour. Tap off any excess flour and then move the cheese stick into the beaten eggs. Swish cheese stick from side to side until completely covered in egg. Tilt to drain excess egg and then put the cheese stick into the fried bread crumbs. Move cheese stick around to completely coat in bread crumbs. You can gently press the breadcrumbs onto the cheese stick to help them stick. Tap off and extra bread crumbs before transferring to a lined baking sheet.
Repeat steps to coat each cheese stick, placing them slightly apart on the baking sheet. (Line with parchment paper or a silicon liner).
Bake in a preheated oven at 400˚for 9-11 minutes or right as you notice cheese starting to bubble. Remove and let cool for just a minute or two then serve warm with a side of marinara sauce and ranch for dipping! (Caution: cheese may be hot at first)
