Place the chicken thighs in a large bowl. In a separate small bowl, mix the salt, garlic powder, onion powder, paprika, thyme, rosemary, and pepper. Set aside 1 teaspoon of this spice mix for later, then sprinkle the rest on the chicken and toss very well. Once everything is evenly coated, drizzle 2 tablespoon of olive oil onto the chicken and toss again.
6 bone-in skin-on chicken thighs, 2 teaspoon kosher salt, 2 teaspoon garlic powder, 2 teaspoon onion powder, 1 teaspoon paprika, 1 teaspoon dried thyme, 1 teaspoon dried rosemary, 1 teaspoon black pepper, 2 tablespoon olive oil
