Preheat oven to 400°F (200°C).
Pulse stale bread in a food processor until you get fine breadcrumbs.
Mix breadcrumbs with Italian seasoning, garlic powder, onion powder, smoked paprika, salt, and pepper.
Set up a breading station: one bowl with flour, one with beaten eggs, and one with seasoned breadcrumbs.
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 tenders 2 minutes per side until golden.
Transfer skillet to oven and bake 12-15 minutes until chicken reaches 165°F internal temperature.
Let rest 3 minutes before serving.
