Step 1

Preheat the oven to 375 degrees F (190 degrees C). Line a glass baking dish with aluminum foil.

Step 2

Spread 1/4 cup of olive oil over the bottom of the prepared baking dish and line up drumsticks on top, alternating directions so that they fit. Top with 1 tablespoon of butter each, on the thick part of the chicken. Sprinkle with garlic salt, seasoned salt, salt, and pepper.

Step 3

Bake in the preheated oven for 35 minutes. Cover chicken with remaining olive oil; continue to bake until juices run clear and chicken is no longer pink in the centers, 10 to 15 more minutes. An instant-read thermometer inserted near the bone should read 165 degrees F (74 degrees C). Serve.
