I’ve been joking with my husband Jack that we should name this delicious Thanksgiving Casserole something like ‘Thanksgiving 2.0’ or ‘Thanksgiving Dinner Round 2’.

But no matter what you call it – this easy Thanksgiving Casserole is a great way to use up your Thanksgiving leftovers and a great way to feed a crowd of family and friends who are staying for the weekend!

This versatile casserole can be made with just about any variety of leftovers you have after your holiday meal.  We layered a mix of turkey, carrots, pearl onions, green beans, and roasted root vegetables in a casserole dish, then covered it with turkey gravy and a layer of mashed potatoes – plus a final sprinkle of cheddar cheese on top. Then we baked it until warm, bubbly and golden on top.

  1. Hey there!
    Excellent recipe! Love the idea of the mashed potatoes on top. So much better than making a soup of leftovers which I usually do.
