In a large bowl, mix together the Greek yogurt, minced garlic, oregano, paprika, black pepper, and a pinch of salt. This will be your marinade.
Add the chicken breasts to the marinade, ensuring each piece is well coated. Let it marinate for at least 15 minutes (or up to 1 hour in the refrigerator for deeper flavor).
While the chicken is marinating, prepare the potatoes. Toss the halved baby potatoes in a bowl with olive oil, salt, and a sprinkle of pepper.
Spread the seasoned potatoes evenly on a large baking sheet. Place the marinated chicken breasts on top of the potatoes.
Generously sprinkle the grated Parmesan cheese over the chicken and potatoes.
Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through (internal temperature should reach 165°F or 74°C) and the potatoes are tender and golden.
Remove from the oven and let it rest for 5 minutes.
Garnish with chopped fresh parsley before serving.
Notes
Serve this dish family-style on a large platter, drizzling any remaining juices from the pan over the top for added flavor.
