Slice each chicken breast into two strips (or three strips if the pieces are large). Place the chicken strips in a bowl and cover with milk. Cover and refrigerate for at least 30 minutes or overnight for best results.

Preheat your oven to 375°F.

In a small bowl, mix together the Greek yogurt, half of the grated Parmesan cheese, salt, garlic powder, onion powder, paprika, and black pepper.

Transfer the chicken strips to a 9×13-inch baking dish and season lightly with salt. Spread the yogurt mixture evenly over the chicken pieces.

Sprinkle the remaining Parmesan cheese on top, then add a little extra paprika for color.

Bake uncovered for 40 minutes. Then switch the oven to broil and cook for a few minutes until the top is golden and slightly browned. Watch carefully to prevent burning.

Remove from the oven and garnish with chopped parsley and chili flakes if desired before serving.
