Thanksgiving Leftovers Breakfast Casserole

For years I had wanted to create a breakfast casserole recipe out of leftover turkey and stuffing. This year I finally did and I couldn’t be more proud. OhioEggs.com asked me to create a breakfast recipe for them using Thanksgiving leftovers, and I knew immediately that there was no more putting it off. This was my chance!

Turkey & Stuffing Breakfast Casserole

This breakfast casserole recipe has a base of stuffing. You’re not making fresh stuffing to go on the bottom layer here (although I wouldn’t blame you if you did!), but instead you’re using leftover stuffing. It’s already cooked and probably a little dried out, which is exactly how you want it.

On top of the stuffing you’ll sprinkle about 2 cups of chopped turkey. If you don’t have turkey leftover, you could use breakfast sausage. Because after all, sausage stuffing is fantastic. If you choose breakfast sausage, crumble and brown the sausage and then drain the fat off before adding it to the casserole.

Then you’ll sprinkle swiss cheese over the turkey. Most breakfast casseroles call for cheese and I didn’t want this recipe to be without cheese either. Swiss pairs just right with turkey and stuffing flavors. Buy a chunk of swiss and shred it yourself. It will only take a minute and your casserole will be creamier than ever!

Dozen Eggs Breakfast Casserole

On top of the cheese you’ll pour a mixture of 12 eggs (yes, one whole dozen!), cream of mushroom soup, a touch of milk and some seasoning. This bakes all around the turkey and stuffing and seals it all together.

One dozen eggs means this is a high protein breakfast perfect for those long, holiday-prep days!

Notes

*If your stuffing is dry, you may want to add a touch more milk. Our stuffing tends to be moist so ¼ cup milk is all we needed. 
**This casserole can be baked immediately or covered and stored in the refrigerator overnight to bake in the morning.
The calories shown are based on the recipe being cut into 15 pieces, with 1 serving being 1 piece. Since different brands of ingredients have different nutritional information, the calories shown are just an estimate.

What a great idea, I love it! Unfortunately, I did not have any Thanksgiving leftovers, but that’s because I didn’t even think about using them for something else (they were offered and I declined). Now I’m disappointed because this is such a fun recipe.

I made this today and it turned out pretty good. This is a very good basic recipe that you can easily customize to your own tastes.

I am going to cut in half. Only two of us. I’ll let you know. I am also going to use heavy cream, and make my version of cream of mushroom soup.
Thank you so much for your perfect leftover use.

Don’t used creme of mushroom soup, just use leftover gravy and maybe a little leftover mashed potatoes and cooked spinach.
