Preheat the oven to 400°F. Line a large-rimmed baking sheet with aluminum foil and spray with non-stick spray. Set aside.
Combine the breadcrumbs, cornstarch, garlic salt, pepper, onion powder, paprika, parsley, and thyme in a gallon-sized Ziploc bag.
1 cup dry breadcrumbs, 1 Tablespoon cornstarch, 1 teaspoon garlic salt, ½ teaspoon pepper, ½ teaspoon onion powder, ½ teaspoon dried parsley, ½ teaspoon thyme, ¼ teaspoon paprika
Add 1 tablespoon of olive oil and mix until the whole mixture is a sandy texture. Then pour the remaining 5 tablespoons of olive oil into a shallow bowl or plate and coat each piece of chicken.
6 Tablespoons olive oil, 1½ pounds chicken breasts
Add the chicken pieces to the bag, one at a time. And shake it around to coat the chicken well. If you want a thicker breading, coat the breaded chicken in oil again, then add it to the bag of breadcrumbs and shake.
The chicken will need to be baked for about 20 minutes or until it reaches an internal temperature is 165 degrees. If using other cuts of chicken, the baking time may vary.
Remove from the oven and transfer the chicken to a cooling rack to rest for a few minutes before serving. Using a cooling rack prevents the bottom of the chicken from getting soggy.
