Instructions
- Preheat oven to 375°F (190°C). Thinly slice potatoes and onion to 1/4-inch thickness. Pat chicken breasts dry and season both sides with salt and pepper.
- Grease a 9x13 inch baking dish with olive oil. Create a single layer of potato slices on bottom, followed by onion slices. Sprinkle with minced garlic and salt. Arrange seasoned chicken breasts evenly over vegetables.
- In a medium bowl, whisk together heavy cream, chicken broth, flour, thyme, paprika, and garlic powder until smooth.
- Pour cream sauce evenly over chicken and vegetables. Cover with aluminum foil and bake for 45 minutes.
- Remove foil and sprinkle cheddar and Parmesan cheeses over top. Return to oven uncovered for 15-20 minutes or until cheese is golden and chicken reaches 165°F internal temperature.
- Let casserole rest for 5-10 minutes before serving to allow sauce to thicken.
Notes
Use Yukon Gold or Russet potatoes for best results. Consistent slicing ensures even cooking. Can be assembled up to 24 hours in advance.
