Sprinkle fried onions over the top.
Bake for 15-20 minutes until warm all the way through.
Notes
Bake in the middle of the oven. It's best to bake on an oven rack in the middle of the oven so the top does not burn before heated through. If you noticed the french fried onions cooking too quick, without the casserole heated through, cover the dish with aluminum foil.To Store:Refrigerator: Refrigerate leftovers in an airtight container for 3-4 days. To Freeze: You can freeze the casserole before or after cooking. When freezing, wrap the pan in two layers of aluminum foil and freeze for up to 6 months.To Thaw: Fully thaw the casserole in the refrigerator overnight, then bake as directed.
