Be sure to fully pat the chicken legs dry, this will ensure nice crispy skin.
Try to find chicken legs that are fairly equal in size to one another. Family packs of chicken tend to have more random sized pieces and are often times fattier. We like to use the smaller packs which are more uniform in size.
Store leftovers in an air-tight container kept in the refrigerator for up to 4 days.
Do not cover the chicken legs with foil when baking. You will end up steaming the chicken instead of roasting it which is what gives it that beautiful golden brown crunchy skin.
If you prefer, you can use olive oil instead of butter with the seasonings.
