Try this Mom's Breaded Pork Tenderloin recipe.
Swapping standard bread crumbs for Japanese panko alters the crunch profile entirely, creating a lighter, shaggier exterior that holds up longer against hot oil. Standard fresh crumbs yield a denser, flatter crust, so adjust your pan temperature accordingly to prevent premature darkening before the interior pork cooks through.
Organize your station linearly using heavy-duty wax paper sheets for flour, the egg-milk wash, and the crumb coating. Beat the three eggs with one teaspoon of milk per egg just until combined; trapping air bubbles in this wash prevents proper adhesion of the outer crumbs. After coating each piece completely with no visible wet spots, transfer the baking sheet to the refrigerator for exactly thirty minutes. This chilling window allows the coating to hydrate and anchor firmly to the meat, stopping the breading from detaching during frying.
Maintain the cooking fat at medium-high heat. Frying on maximum heat carbonizes the edges instantly while leaving the interior raw. Because the tenderloin portions are pounded very thin with a mallet, cooking requires only moments per side. Transfer finished cutlets to paper towels to drain excess fat, then hold them in a 200 degrees Fahrenheit oven on a wire rack to preserve crispness while you finish remaining batches.
