Before you begin cooking line a large baking tray or broiler pan with foil for easy clean up. If you do not have a broiler pan just use a large baking tray with a cooling rack on top. Also move your oven rack so it is 8 to 10 inches below the broiler, for my oven this was just below the middle. Preheat your oven to broil.

Combine the butter, lemon zest, garlic, 1/4 teaspoon salt and pepper. Mash with a fork to make a paste and combine everything. Spread the butter under the skin of all the chicken thighs, I find this is easiest with your fingers. After they all have butter on them place them on the baking rack skin side up and give them a good sprinkle of salt and pepper and drizzle them with the olive oil. Place the lemon on the tray cut side down. Put this under the broiler for 10 minutes. At this point make sure the skin is not getting to brown, if it is you need to lower your rack one more time.

After 10 minutes remove the tray and flip the chicken and lemon and cook for an additional 20 minutes. Remove and flip the chicken one more time so the skin is up again remove the lemon and set aside to cool. Cook one more time for another 10-15 minutes. Remove and squeeze the lemon juice on top. Serve with your favorite veggies or potatoes.
