Preheat oven to 350 degrees.
Combine salt, dried oregano, garlic powder, black pepper, and crushed red pepper flakes in a small bowl. Set aside.
Pat chicken drumsticks dry with paper towels. Set aside.
Scrub potatoes and cut into 1-inch chunks.
Arrange potatoes and drumsticks in a 9 x 13-inch baking pan. Sprinkle with seasoning mixture, making sure some seasoning gets under the skin of the chicken. End by pulling the skin of each chicken leg up over the meat, so the meat is covered and the skin is on top.
Drizzle the chicken and potato mixture with lemon juice, then olive oil.
Cover pan with foil. Bake at 350 degrees for 40 minutes.
Remove foil and raise oven temperature to 400 degrees. Bake an additional 20 minutes until browned.
Optional: Placed the finished dish under the broiler for 3-4 minutes to make the chicken skin more browned and crispy. Watch carefully so it doesn't char.
