Preheat your oven to 350°F (180°C). If you have a fan oven, adjust to 160°C. This ensures an even cook on your chicken.
Line a baking sheet with aluminum foil or parchment paper. This makes for an easier cleanup later, which I always appreciate.
In a large bowl, combine the chicken thighs with olive oil, kosher salt, garlic powder, onion powder, paprika, cayenne, and black pepper. Toss everything together well to coat the chicken evenly with the seasoning.
Place the chicken thighs on the prepared baking sheet in a single layer. Make sure they’re not touching to ensure they bake evenly.
Bake in the preheated oven for 15 to 20 minutes. You’re looking for the internal temperature to reach 165°F (74°C). A meat thermometer is your best friend here!
If you want a crispy finish, place the chicken under the broiler for a couple of minutes. Just keep an eye on them so they don’t burn!
Once done, remove the chicken from the oven and let it rest for about 5 minutes. This step is crucial, as it helps the juices redistribute throughout the meat.
Serve the baked chicken thighs with your choice of sides, like mashed potatoes, rice, pasta, salad, or steamed veggies. Enjoy every single bite!
