Preheat your oven to 375°F (190°C).
In a bowl, mix lemon juice, chicken broth, olive oil, garlic, oregano, salt, and pepper.
Place chicken breasts in a baking dish.
Pour the lemon mixture over the chicken, ensuring they are well coated.
Cover the dish with foil and bake for 15 minutes.
Remove the foil and bake for an additional 5-10 minutes until the chicken is cooked through.
Check the internal temperature—it should reach 165°F (75°C).
Let the chicken rest for a few minutes before slicing.
Drizzle some of the cooking juices over the sliced chicken.
Garnish with fresh parsley and lemon slices before serving.
