Wash the chicken legs and pat them dry with paper towels. Sprinkle coarse salt on the chicken legs and mix well. Leave the chicken uncovered and put in your refrigerator for at least 4 hours and up to 24 hours. The meat should not be covered, the drying will help the skin get a little crispy when roasting. For the seasonings, to a bowl, add garlic powder, fresh ground black pepper, smoked paprika and dried thyme, mix well. Heat your oven to 400 degrees Fahrenheit/205 degrees Celsius. Mix up the spices right before you take the chicken out of the fridge. I left the chicken in the fridge for about 18 hours. Pat the chicken dry with paper towels. You don’t need to rinse them.
