Preheat the oven to 375°F (190°C) and lightly coat a 9x13 inch baking dish with non-stick spray.
In a medium mixing bowl, combine the Greek yogurt, grated Parmesan cheese, minced garlic, oregano, paprika, salt, black pepper, and lemon juice.
Pat the chicken breasts dry with paper towels to ensure proper adhesion of the coating.
Arrange the chicken breasts in a single layer in the prepared baking dish.
Spread the yogurt mixture evenly over the top and sides of each chicken breast.
Bake for 25 to 30 minutes, or until the internal temperature reaches 165°F (74°C) as measured by a meat thermometer.
Remove from the oven and allow the chicken to rest for 5 minutes before slicing and serving.
