Preheat the oven to 375F. Season the chicken breasts with salt, pepper, lemon juice and paprika.
Heat a cast iron skillet over a high heat and drizzle in the olive oil. Place the chicken into the heated oil in the skillet and sear on each side for 3 - 4 minutes until the chicken is golden brown on both sides.
Once the breasts are seared just pop the skillet into the preheated oven and bake for 15 - 20 minutes depending on the thickness of your chicken breasts. You can test it by checking the internal temperature, it should be 165F. Let the chicken rest for 5 minutes before serving it.
