3️⃣ Preheat oven to 400°F (200°C). 🔥

4️⃣ Heat oil over medium-high heat in a large oven-safe skillet. Season the chicken all over with salt and pepper, to taste. When the pan is hot and the oil is shimmering, add the chicken to the skillet in a single layer. Cook for 1-2 minutes on each side or until lightly golden brown. 🍳
