Method
Preheat and prep
- Preheat the oven to 375°F and grease a 9x13 baking dish so the sauce won’t stick.
- Season the chicken breasts on both sides with salt, pepper, garlic powder, and onion powder, then place them in the prepared baking dish.
Make the creamy sauce
- Whisk together cream of chicken soup, sour cream, mayonnaise, ranch seasoning mix, and garlic powder until smooth.
- Pour the cream sauce evenly over the chicken so each breast is completely coated.
- Top the casserole with the Parmesan cheese so it can brown as it bakes.
Bake and serve
- Bake at 375°F for 28–32 minutes, until the sauce is bubbly and golden and the internal temperature reaches 165°F.
- Garnish with fresh parsley and serve the creamy chicken over pasta or rice.
Notes
For the thickest sauce, spread the cream mixture to the edges of the dish before adding the Parmesan so it can caramelize. Refrigerate leftovers in an airtight container for up to 3 days; reheat covered in the oven or microwave until hot (165°F for best results). Freezing is not recommended because sour cream and mayonnaise can break during thawing. For a lighter option, swap the mayonnaise for light mayonnaise and use reduced-fat sour cream if desired.
