Preheat your oven to 400°F (200°C). This high temperature will help achieve that golden, crispy skin.
In a large mixing bowl, combine the Panko breadcrumbs, cornmeal, kosher salt, garlic powder, paprika, onion powder, thyme, oregano, and black pepper. Mix well until all ingredients are evenly combined.
Pat the chicken thighs and legs dry with paper towels. Drizzle the olive oil over the chicken, making sure each piece is well-coated.
Place a few pieces of chicken into the resealable plastic bag with the breadcrumb mixture. Seal the bag tightly and shake until the chicken is fully coated. Repeat this process until all chicken pieces are coated.
Line your baking sheet with parchment paper or aluminum foil for easy cleanup. Arrange the coated chicken pieces skin-side up on the sheet, making sure they are not touching. This helps them cook evenly.
Bake in the preheated oven for 35-45 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the coating is golden brown and crispy. If you want extra crispiness, you can broil them for the last 2-3 minutes—just keep an eye on them!
