In a small bowl, whisk together the minced garlic, lemon juice, lemon zest, olive oil, dried oregano, salt, and pepper.
Place the chicken breasts in a baking dish and pour the lemon garlic marinade over them, making sure they are evenly coated. You can also marinate the chicken for 30 minutes to an hour for more flavor.
Bake the chicken in the preheated oven for 25-30 minutes, or until the chicken is cooked through and no longer pink in the center. You can also check the internal temperature with a meat thermometer; it should read 165°F (75°C).
Once cooked, remove the chicken from the oven and let it rest for a few minutes.
Serve the lemon garlic chicken hot, garnished with fresh parsley if desired.
Enjoy your delicious and flavorful Lemon Garlic Chicken!
