Preheat oven to 400 degrees Fahrenheit (200 degrees Celsius) and line a baking sheet with parchment paper.
Organize three shallow containers for the breading station: one with flour, one with beaten eggs, and one containing the Panko, Parmesan cheese, garlic powder, oregano, salt, and pepper.
Dredge chicken tenders in flour and shake off any excess.
Dip chicken into the egg wash until fully submerged, then let excess drip off.
Press the chicken firmly into the Panko-Parmesan mixture to ensure even adherence.
Arrange tenders on the prepared baking sheet and apply a light coating of cooking oil spray.
Bake for 15 to 18 minutes, flipping once at the halfway point, until the internal temperature reaches 165 degrees Fahrenheit (74 degrees Celsius).
In a small bowl, whisk together Dijon mustard, honey, and 1 tablespoon of mayonnaise for the honey mustard sauce.
In a separate small bowl, combine remaining mayonnaise, minced garlic, and lemon juice for the garlic aioli.
Serve the hot chicken tenders immediately with the prepared dipping sauces.
