Preheat Oven : Preheat oven to 400°F (200°C) and lightly grease or line a baking sheet with parchment paper.
Prepare Honey Mustard Dip : In a small bowl, whisk together mayonnaise, Dijon mustard, honey, lemon juice, salt, and pepper. Refrigerate until ready to serve.
Prepare Chicken Tenders : Set up a dredging station with three shallow bowls: Flour seasoned with salt, pepper, paprika, garlic, and onion powder. Beaten eggs mixed with milk. Panko breadcrumbs mixed with Parmesan (optional). Coat each chicken tender first in flour, then egg, then panko mixture, pressing gently to adhere.
Bake the Tenders : Arrange chicken tenders on prepared baking sheet. Lightly spray with cooking spray or drizzle with a little oil. Bake for 15–20 minutes, flipping halfway, until golden brown and cooked through (internal temperature 165°F/74°C).
Serve : Serve warm with honey mustard dip on the side.
