Preheat the oven to 375°F (190°C).

In a bowl, mix together garlic, oregano, thyme, olive oil, salt, pepper, and lemon juice to create the marinade.

Place the chicken breasts in a baking dish and pour the marinade over them, ensuring they are well coated.

Cover the dish with plastic wrap and marinate in the refrigerator for at least 30 minutes, or up to 2 hours for more flavor.

Remove the chicken from the refrigerator and let it sit at room temperature for about 10 minutes.

Bake in the preheated oven for 25-30 minutes, or until the internal temperature reaches 165°F (75°C).

Remove from the oven and let the chicken rest for 5 minutes before slicing.
