Notes

For the creamiest casserole, use shredded chicken that’s fully cooked and not watery, and make sure the cheese is evenly distributed so it melts into a golden crust. Store leftovers covered in the refrigerator for up to 3-4 days; reheat in the oven or microwave until hot. Freezing is not recommended because sour-cream-based casseroles can separate when thawed. For a lighter option, swap sour cream with plain Greek yogurt for a similar tang.
