Easy Thanksgiving Leftover Casserole

Thanksgiving is filled with lots of food.  And most of the time we never eat it all.  I mean, how can you?  Between the amazing turkey,  traditional green bean casserole, flavorful stuffing, creamy mashed potatoes, corn, rolls and the gravy to pour on top of everything you always end up Thanksgiving leftovers.  Which isn’t a bad thing, Thanksgiving leftovers are just as delicious as the original meal.  But sometimes we need a little inspiration on how to repurpose those yummy Thanksgiving leftovers.

Which is exactly why I made the tastiest and easiest Thanksgiving Leftover Casserole you will ever have.  You literally layer all your Thanksgiving leftovers into a casserole dish, bake and enjoy.  And don’t we all deserve an easy meal after all that cooking we did on Thanksgiving?  Yes, yes we do.

In this Thanksgiving Leftover Casserole you will use these ingredients:

Leftover Turkey
Leftover Cranberry Sauce
Canned corn – fresh is fine too
Leftover green bean casserole
Leftover Stuffing

You can top your casserole with candied pecans and fresh cranberries before serving, like I did.  It gives your casserole a bit of color and a bit of crunch…both were a perfect Thanksgiving addition, but it is just as good without them if you would rather not add them.

Those are our Thanksgiving dinner staples, if you have anything else leftover that you think may be good in your Thanksgiving leftover casserole, go ahead and add it in.

I recommend serving my leftover casserole with a tall glass of cold milk. Milk contains nine essential nutrients and 8 grams of high-quality protein in every 8-ounce glass.
