Thanksgiving is upon us and that means one thing: ALL THE LEFTOVER TURKEY. It’s here and it needs to be used up before it goes bad. 

It used to stress me out every Black Friday…I have all this turkey and I feel such pressure to use it. Can you relate? 

I’ve now gotten a few favorite recipes that we make every year to use up that leftover turkey.

One of them is obviously a sandwich made with leftover rolls, stuffing, cranberry sauce, and whatever other goodies we might want to shove on there. You can’t go wrong with that.

We also make leftover turkey soup and leftover turkey casserole every year along with this turkey tetrazzini recipe. 

This easy turkey tetrazzini is absolutely packed with creamy, cheesy goodness, fresh mushrooms, and of course…turkey. We love it and I bet you will too!

Did I mention that it’s ready to go in about 40 minutes? I love when comfort food comes together fast!

How to make this turkey tetrazzini recipe: 

sauteed mushrooms in skillet

To start, you’ll want to saute some fresh mushrooms, onions, and garlic in a bit of butter. Your house is going to smell divine. 

Add the veggies to a large mixing bowl with some cooked egg noodles, leftover turkey, cream of celery soup, and sour cream. Season it up with salt and pepper.

Spread this creamy goodness into a baking dish and top it off with a mix of mozzarella and Parmesan.

This casserole bakes in about 25 minutes. It’ll come out hot, cheesy, bubbly, and delicious.

We sprinkle with fresh herbs before serving…parsley, basil, dill, whatever I have on hand really works great here. 


  • Turkey: Make this recipe all year long using cooked, chopped chicken in place of the turkey!
  • Cream of Celery: Use cream of mushroom or cream of chicken, if you prefer. You can even use my homemade substitute for cream of chicken soup, if you don’t like the canned goop.
  • Dried Egg Noodles: Use the frozen variety, if you like the thicker cut! You can even swap in macaroni or penne.
