Leftover Thanksgiving Casserole

Sharing is caring!

Leftover Thanksgiving Casserole is a scrumptious dish loaded with all your favorite Thanksgiving favorites, from the stuffing to the green bean and gravy. It’s a great way to use up those leftovers.

I have a problem every year after Thanksgiving…besides the few extra inches to the waist line! It’s all the Leftovers! 

Casserole made with leftovers from Thanksgiving

There’s the delicious Turkey sandwiches, and that re-heated third plate, but what now? There’s still a container of Stuffing…a few green beans, some gravy, and the Turkey and Ham lurking around in the refrig.

What to do?

I decided this year to take them all and create this scrumptious casserole. It hints at Chicken Cordon Bleu only creamier and a lot easier to make!

How To Make Leftover Thanksgiving Casserole

Start by digging out your leftovers. Begin with a layer of left over stuffing and a 9 x 13 pan.

Just toss it in there. Doesn’t have to be pretty. This casserole is more about taste and flavor than appearance. Although I do happen to think it looks pretty darn good!

Add your leftover vegetables. I had green beans, but you could use broccoli or mixed vegetables. I had about a cup of green beans.

We aren’t stressing over exact ingredients in this dish. Our goal is to use up those leftovers before they start becoming a science project! Lol

Dice up about 3 cups of meat. I did Turkey and Ham. If you don’t have both just do one or the other. The great thing about this casserole is “Leftover” aspect. It’s what you have on hand.

I had Turkey, but no ham. However, I wanted to use both, so I bought a slice of ham steak and diced it up.

How to make Creamy White Sauce

It’s starting to come together. All that’s left is to make the “white sauce” and add some cheese.

For the white sauce we need to start out with a Roux by melting 6 Tablespoons of butter in a medium skillet.

Add a pinch of flour. Stir it with a whisk. Once that starts to bubble… Add 1/4 cup of flour and continue to stir until a thick paste forms.

Add in 1 cup of milk plus salt and pepper to taste, continue stirring over medium heat.

A rich thick white gravy will form. If it’s too thick add a little more milk. Continue to stir.

If you have some leftover gravy this is the time to add it! It adds a wonderful flavor and depth to this sauce. It doesn’t look pretty, but trust me when I say…it’s delicious! I added about 3/4 of a cup.

Adding White Sauce to Leftover Casserole

Once that is all incorporated, pour the sauce over the casserole ingredients.

Doesn’t that look delicious?

Sprinkle with 2 cups of shredded Swiss Cheese. Yep… Swiss Cheese. This is where that hint of Chicken Cordon Bleu comes in to play and takes it from tasting like another plate of Thanksgiving leftovers into something new and exciting.

The Swiss cheese kicks up the flavor of this casserole and adds a delicious twist!

In a microwave safe cup, melt 1 Tablespoon of butter, add 1/4 cup Italian Bread Crumbs. Mix it together. Then Sprinkle the top of the cheese with the buttered Italian seasoned bread crumbs. Yummmmm!

How to Bake Casserole

Pop into a preheated 350° oven and bake for 30 – 40 minutes. Cheese should be melted, and the bread crumbs crispy and golden, the sauce bubbly. Then it’s done and perfect!

We have this rating system game we do…thumbs up if it’s a keeper. Thumbs down if they don’t ever want to see it on the dinner table again, and side way thumbs if it’s an “Eh, I could take it or leave it!”

I’m happy to announce… My family gave this casserole TWO enthusiastic thumbs up! (Whew! The pressure was on!)

Serving Leftover Thanksgiving Casserole

It’s so good… I even ate the leftovers of the Leftover Casserole! I think that’s saying a lot! (Besides I’m too lazy to make something else!) 

This casserole is magical! It makes all your Thanksgiving leftovers disappear! (Face it…after a week we all want that.) 

What’s even better than that, and would make my grandma so happy, is that we aren’t throwing out all that perfectly good food! We are feeding our families a delightful appetizing dish without wasting. A true win-win!
