Cover a sheet pan with aluminum foil (I wasn't thinking when I made this most recently and used parchment paper, which isn't the best to use in a high temp oven). Lay the chicken legs on the foil and drizzle/rub with olive oil. Sprinkle with your favorite seasoning (I use Nature's Seasoning). Cook for about 40-45 minutes at 425 degrees.
Your house will smell amazing! The skin gets crispy and the meat is so very juicy and flavorful!
