Start by preparing Caesar dressing
Preheat oven to 375
Spray a 9x13 dish with non stick spray. Lay chicken in dish.
Sprinkle chicken with half of the parmesan cheese and pepper, Do not salt the chicken
Mix together dressing and sour cream in a bowl.
Pour the dressing/sour cream mixture over chicken and sprinkle on remaining parmesan cheese.
Bake at 375 for 30 minutes or until a meat thermometer reaches 165
Next, place chicken under the broiler for about 2-3 minutes, until the chicken turns golden brown. This can happen FAST - keep a close eye on it.
Remove from broiler and cover loosely with foil and let sit and rest for 5-10 minutes before serving. Garnish with chopped fresh parsley if desired.
