Preheat the oven to 375 degrees F. Line a large rimmed baking sheet with parchment paper and set aside.

In a large bowl, combine olive oil, rosemary, lemon zest, garlic, lemon juice, salt, and pepper. Add chicken and toss, throughly coating with the mixture.

Arrange the chicken skin side down on the prepared baking sheet. Bake for 30 minutes, then flip and continue baking for additional 25-30 minutes until completely cooked through. The skin should be golden brown when finished baking.
