Preheat your oven to 400°F (200°C).
Place stale bread pieces in a food processor and pulse until you have fine breadcrumbs.
Mix breadcrumbs with Italian seasoning, garlic powder, onion powder, smoked paprika, salt, and pepper in a shallow dish.
Set up a breading station: flour in one dish, beaten eggs in another, and seasoned breadcrumbs in a third.
Dredge each chicken tender in flour, then dip in egg, and finally coat with breadcrumbs.
Heat olive oil in an oven-safe skillet over medium-high heat.
Sear chicken tenders for 2 minutes on each side until golden.
Transfer skillet to oven and bake for 15 minutes until chicken is cooked through (165°F internal temperature).
