Heat the oven to 425°F. Lightly oil a large sheet pan, or use parchment paper.
In a shallow bowl, combine the oat crumbs, salt, pepper, and paprika.
In another bowl, beat the eggs or pour in the milk.
Dip each chicken tender in the egg or milk, then coat it in the oat mixture, pressing lightly so the crumbs stick.
Place the coated tenders on the prepared pan, leaving a little space between each one.
Bake for 12–15 minutes, turning once halfway through, until golden brown and cooked through.
For extra crispness, broil for 1 minute at the end.
