Ingredients
  

  • 4 boneless, skinless chicken breasts
  • 3/4 cup Parmesan cheese finely shredded
  • 4 slices mozzarella cheese
  • 1 cup sour cream rich
  • 1 tbsp cornstarch
  • 1 tsp dried oregano
  • 1 tsp garlic powder
  • 1 pinch salt
  • 1 pinch black pepper
  • cooking oil for greasing the dish

Instructions
 

  • Set your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish with oil.
  • Lay the chicken breasts flat in the baking dish and season with a pinch of salt and pepper if desired.
  • In a mixing bowl, combine sour cream, 1/2 cup Parmesan cheese, salt, pepper, oregano, garlic powder, and cornstarch. Stir until smooth.
  • Place a slice of mozzarella cheese on each chicken breast. Spread the sour cream mixture over the chicken, then sprinkle with remaining Parmesan.
  • Bake in the oven for about 1 hour, or until the chicken reaches 165°F (74°C) and the cheese is golden and bubbly.
  • Remove from the oven and let it rest for a few minutes to allow the sauce to thicken.
  • Sprinkle with fresh parsley or chives and serve warm.
