In a medium mixing bowl, combine the lemon zest, lemon juice, black pepper, garlic powder, onion powder, smoked paprika, and a pinch of salt. Whisk everything together until well blended, creating a vibrant marinade.
Add the chicken tenders to the marinade, making sure each piece is fully coated. Cover the bowl with plastic wrap or a lid and refrigerate for at least 30 minutes, allowing the flavors to infuse (up to 2 hours for even more intense flavor).
While the chicken is marinating, prepare a dredging station by setting out three shallow dishes. Fill the first dish with flour, the second with the beaten eggs, and the third with panko breadcrumbs.
Remove the marinated chicken tenders from the refrigerator. Taking one tender at a time, first coat it in flour, shaking off any excess.
Next, dip the floured tender into the beaten eggs, ensuring it is fully coated before allowing any drips to fall back into the dish. Finally, transfer it to the panko breadcrumbs, press gently to ensure a well-adhered coating. Repeat for all tenders.
Heat a generous amount of olive oil (about ¼ inch deep) in a large skillet over medium heat. When the oil is shimmering, carefully add the breadcrumb-coated chicken tenders in batches, without overcrowding the pan to ensure even cooking.
Fry the chicken tenders for approximately 4-5 minutes on each side, or until they develop a golden brown crust and the internal temperature reaches 165°F (75°C). Adjust cooking time as necessary based on your skillet and stove.
Once cooked, transfer the chicken tenders to a paper towel-lined plate to drain any excess oil and maintain their crispiness.
Notes
For extra brightness, drizzle lemon juice over the tenders just before serving.
