Place the chicken breasts between two pieces of plastic wrap, then pound into an even thickness, anywhere from .6 to .8 of an inch thick. Adjust the thickness of all of the pieces to match your thinnest chicken breast so that they are all the same size.
Whisk together the seasoning in a small bowl.
Line a tray with parchment paper. Rub each chicken breast with olive oil then sprinkle with the seasoning, covering the surface in an even layer, covering the chicken as much as you like. Place each chicken breast on the parchment paper.
Bake for 18-20 minutes until the internal temperature is 165°F using an instant read thermometer.
Remove from oven and transfer to your serving platter. Let rest 2-3 minutes, then serve.
Making sure that the chicken is the same thickness ensures a tender, juicy chicken breast that cooks quickly and evenly!
