Start by preheating your oven to 375°F (190°C). Then, take your chicken breasts and place them between two sheets of plastic wrap. Use a meat mallet or rolling pin to gently flatten them to an even thickness. This step is crucial as it ensures even cooking.

In a small bowl, mix together the kosher salt, smoked paprika, onion powder, black pepper, lemon zest, and thyme. This blend is aromatic and ensures that your chicken will have a rich flavor profile. Rub the mixture evenly over the chicken breasts.

Drizzle melted ghee or olive oil on a baking dish. Place the seasoned chicken breasts into the dish, ensuring they’re not crowded. Spacing them will help them roast instead of steam.

Slide the baking dish into your preheated oven. Bake for about 25-30 minutes, or until the internal temperature reaches 165°F (75°C). A digital meat thermometer is your best friend here.

Once baked, remove the chicken from the oven. Let it rest for about five minutes. This step allows the juices to redistribute, resulting in a juicy bite every time.

Slice your chicken against the grain and serve. Pair it with your favorite sides for a satisfying meal.
