This easy turkey tetrazzini recipe creates a creamy homemade sauce (no canned soups!) with fresh mushrooms and leftover turkey. Similar to chicken tetrazzini this recipe can be adapted using rotisserie chicken for an easy casserole dinner.
It’s time to make a turkey just to create and enjoy this turkey tetrazzini recipe. I kid. (Sort of.) This is the perfect recipe to make with your leftover turkey this coming Thanksgiving. In fact I made this with my leftover turkey that was in my freezer. That means delicious turkey tetrazzini long after the fall decorations were put away.
This recipe is based on a super simple homemade roux sauce that is coupled with fresh mushrooms bringing a savory taste to this casserole classic. The original recipe comes from my parent’s good friends in college and after finding this delicious traditional recipe – I am looking forward to making it again soon!
How to Make Turkey Tetrazzini
Cook and drain 8 oz of spaghetti. While the pot is boiling, sauté the mushrooms in butter. Set the mushrooms aside to make the homemade creamy sauce.
Turkey Tetrazzini Homemade Sauce
Melt butter in the pan you used for your mushrooms that have now been removed. Add the flour and stir until combined into a paste. Add the chicken broth and let simmer while stirring until it thickens. After thickening add the milk, sherry, salt and pepper.
In a large bowl combine the mushrooms, pasta and creamy homemade sauce.
Add to a 13×9 pan and sprinkle with shredded parmesan cheese.
Bake at 350˚ F for 25 minutes or until bubbly. Serve warm.
This is seriously one of my favorite savory casserole recipes. The sherry gives it a depth of flavor that is just absolutely delicious. And while you can make this recipe using chicken, I highly recommend making it with all that leftover turkey you’ll have this season.
Enjoy!

good- enjoyed it
This turned out soupy? And the cream separated? The flavor was good. But it did not thicken up. Not sure why. I followed insteuctions. I did use whole grain wheat flour instead of white? Could that be it?
Made this tonight and it was very good! I added a few cloves of garlic and used 12 oz. Jovial gluten free spaghetti. I also used leftover rotisserie chicken.
