Preheat your oven to 200 C (400 F). Grease a baking dish, say a 7x11 dish, with butter or olive oil using a oil mister.
Heat the olive oil in a non stick pan on medium heat, when hot, add the garlic and stir for 1 minute until fragrant. Do not burn the garlic, no one likes burnt garlic.
To the pan, add the broth, lemon zest and juice, oregano, and the thyme leaves, stir then pour this into the prepared baking dish.
Season each side of the chicken breasts with salt and pepper as desired, then place into the dish along with the lemon wedges and sprigs of thyme. If not using fresh sprigs, sprinkle some dried thyme over the chicken.
Bake for 30-40 minutes, spooning the liquid over the chicken 2 to 3 times. Cook until the juices run clear from the chicken and it is cooked through.
Remove from the oven and let rest for 5 minutes, serve and spoon the juices from the baking dish over the chicken.
