Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it for easy release after baking.
If your chicken tenders are very thick, you can lightly flatten them to an even thickness with a quick gentle pound; this helps them cook evenly.
Set up a coating station: place the beaten eggs with milk in a shallow dish. In a separate dish, mix the crushed pretzels, breadcrumbs, Parmesan, garlic powder, paprika, salt, and black pepper.
Dip each chicken tender into the egg mixture, letting the excess drip off, then roll it in the pretzel-breadcrumb mixture. Press gently to ensure the crust adheres well all around.
Place the coated tenders on the prepared baking sheet. Lightly spray or brush the tops with a bit of oil to help with browning.
Bake for 12–15 minutes, flipping once halfway through, until the crust is golden and the chicken reaches an internal temperature of 165°F (74°C). If you like a crisper crust, switch to broil for 1–2 minutes at the end, watching carefully to avoid burning.
Rest the tenders for a couple of minutes before serving. This helps the juices redistribute and keeps the crust intact when you bite into them.
