Heat a large oven-safe (cast iron) skillet over medium high heat and add the oil.
Coat the pan with the oil and add the chicken drumsticks, seasoning them with salt and pepper before adding them to the pan.
Brown the chicken on all sides just to give it some colour, for a couple minutes per side.
While the chicken browns, combine the melted butter, garlic, herbs, and lemon juice. Slice the lemon.
Brush the chicken with the melted butter mixture and pour any remaining over the chicken in the skillet. Add the lemon slices in between the chicken pieces and add the pan to the oven.
Bake for about 15-20 minutes, or until the chicken has reached an internal temperature of 165 degrees Fahrenheit (74 Celsius).
Serve with potatoes, rice, or any side dishes you prefer.
Notes
This recipe can be made with any bone-in chicken, however cook times will vary depending on the size of the chicken pieces.
