Preheat your oven to 400°F (200°C). While the oven heats, take your chicken thighs and pat them dry with paper towels.
In a large skillet, add 2 tablespoons of olive oil over medium-high heat. Once hot, gently place your chicken thighs skin-side up into the skillet. Season them evenly with salt and black pepper.
Let the chicken sear on the first side for about 3 to 4 minutes until it’s golden brown. Afterward, flip the chicken and sear the other side for another 3 to 4 minutes.
Once seared, transfer the chicken to a baking dish. If you used an ovenproof skillet, you could keep it in the skillet.
In a separate bowl, combine the garlic, the juice of 2 lemons, rosemary, lemon zest, and the remaining 2 tablespoons of olive oil. Whisk until well blended.
Pour this flavorful mixture evenly over the chicken in the baking dish.
Bake uncovered for about 25 to 30 minutes. Keep an eye on it, and ensure the chicken reaches a safe internal temperature.
Once done, allow the chicken to rest in the pan for about 5 minutes. This resting period is vital; it allows the juices to redistribute.
Finally, garnish with fresh lemon slices and additional rosemary, if desired. Serve your Baked Lemon Rosemary Chicken with your favorite sides.
