In a large mixing bowl, combine the halved baby potatoes, minced garlic, olive oil, oregano, thyme, salt, and pepper. Toss until the potatoes are well coated.
Spread the seasoned potatoes on one side of a large baking dish.
Season the chicken breasts with salt and pepper, then place them on the other side of the baking dish.
In a small bowl, mix together the grated Parmesan cheese and a tablespoon of olive oil until it forms a paste. Spread this mixture evenly on top of each chicken breast.
Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through (internal temperature of 165°F/74°C) and the potatoes are tender and golden brown.
If desired, broil the dish for an additional 2-3 minutes to get a crispy top on the chicken.
Remove from the oven and let it rest for a few minutes before serving. Garnish with freshly chopped parsley.
Notes
For a crispy top, broil for an additional 2-3 minutes.
