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 tsp kosher salt, 2 tsp garlic powder, 2 tsp onion powder, 1 tsp paprika, 1 tsp dried thyme, 1 tsp dried rosemary, 1 tsp black pepper, 2 tbsp olive oil
