Preheat the oven to 450°F (225°C).
Grease the baking pan generously with the butter or oil and place the chicken drumsticks on the pan. Salt and pepper to taste.
Drizzle the lemon juice and olive oil over the chicken pieces. Sprinkle the garlic and parsley on top.
Bake the chicken until golden and the garlic slices have turned brown and roasted for about 30–40 minutes or until the internal temperature reaches at least 165°F (74°C). The baking time may be longer if your drumsticks are on the larger size. You can lower the temperature a little towards the end of the baking time if your drumsticks are becoming too dark.
