Preheat your oven to 350°F (175°C).
Lightly grease a baking dish with 1 tbsp of oil.
Arrange the chicken breasts evenly in the dish.
In a bowl, mix Catalina dressing, apricot preserves, dry onion soup mix, and red pepper flakes.
Pour the mixture over the chicken, coating it well.
Drizzle remaining oil on top for a golden finish.
Bake uncovered for 35 minutes, or until chicken is fully cooked and sauce is bubbling.
Garnish with fresh parsley if desired, and serve hot.
