Turkey Tetrazzini

Sharing is caring!

This creamy and comforting Turkey Tetrazzini is one of my favorite meals to make with leftover Thanksgiving turkey. It works equally well with leftover chicken and I often buy rotisserie chicken to use.

In my opinion, the mushrooms and peas are essential for a tetrazzini. They’re my favorite part and I’ll admit that whenever I dish myself up, I always dig for a few extra mushrooms. A splash of sherry and a pinch of nutmeg also add wonderful flavor to a tetrazzini.

That being said, Turkey Tetrazzini is very adaptable and forgiving and you can leave any of these ingredients out to suit your taste. Try adding broccoli or even green beans instead of peas or mushrooms.

Because when you have a creamy, cheesey sauce pretty much anything tastes good in it.

Quite a few Turkey Tetrazzini recipes use Condensed Soup to make preparation quick and easy and I make a lot of casseroles using condensed soup, including tetrazzini on occasion. But this one is from scratch with a creamy sauce made from butter, flour, chicken broth, milk, and heavy cream. If you don’t like cooking with canned soup, this is a great recipe to try.

Turkey Tetrazzini - always a family favorite!

Like most casseroles, Turkey Tetrazzini can be made ahead of time. Another reason it’s a family favorite. Just get it all assembled, wrap with plastic wrap and store in the refrigerator for up to 24 hours. Take it out, discard the plastic wrap and add a few minutes to the baking time. You have yourself a hassle free weeknight meal.

Everyone will want seconds of this hot and creamy meal.

  1. My family who are picky eaters loved this. Will be added to our regular set of meals. Thanks for the recipe, I love that it was so simple to make with very little cleanup.

  2. I tend to jazz up most to the recipes. Many mid-westerners eat things that are really bland. I’m from the Southwest, and we eat everything with bold flavoring. Haven’t tried this but I’m going to. Pay no attention to people who don’t think anyone should voice an opposing opinion. It’s just the internet.

  3. Delicious! I added a couple cloves of garlic and a shallot and substituted the sherry with white wine. This recipe is definitely a keeper and not just for thanksgiving leftovers, but I will use it with leftover chicken throughout the year too.

    1. I, too, made this for my husband and I after all the family and friends have left. When I made it, I didn’t want to use peas or spinach so I use a can of Italian string beans with the water poured off. I also use Italian seasoning and mushrooms. It made into a really tasteful casserole and I served jellied cranberry sauce and rolls. Nice variation to the Christmas turkey leftovers.

  4. I made this with leftover Thanksgiving turkey, I also added a shallot, to the mushrooms in the butter.
    Delicious, thank you!

  5. I added half an onion sautéed in butter, plus sautéed with that 2 cloves of garlic to the mushrooms. I added peas and carrots too. I topped it with Italian bread crumbs for more flavor. My turkey was left over from a smoked turkey and the flavor was fantastic. It was Amazing! I also used gluten free pasta and was glad for a no-canned soup recipe. My flour was gluten free too so you can adapt this as you may need to.

  6. Delicious! Best casserole I have made in ages. A great combination of flavors. The fresh ingredients made a huge difference.

  7. This is an excellent recipe and wonderful for that leftover Thanksgiving Turkey. I made as stated with exception of one small onion and 3 cloves garlic that I sautéed first. I also added one small jar of pimentos (drained) for some pretty color. Thank you for this recipe. A keeper.

  8. I found this recipe today while searching for something to do with the leftovers from Thanksgiving. It’s scrumptious !!! Highly recommended !

  9. Excellent recipe and post! My husband and I loved this. I will definitely keep making it in the future! Thank you for sharing 🙂

  10. Making this again this afternoon but with left over chicken instead of turkey. We love it as a healthier alternative to the canned soup version.

  11. My daughter was going to toss a turkey carcass that had so much on it that I thought of this dish. I mentioned it to her but the she wasn’t interested….what is up with the 20-50+ generation. Haven’t they heard of “waste not want not ” rule?

  12. My family’s not a fan of mushrooms or peas so I substituted with one large red pepper that I diced and sautéed in 2 tablespoons of butter. I also used broccoli which I steamed for about 6 minutes. This will be the new go to post-Thanksgiving meal.

  13. Wow, this was really great! It had so much flavor, the only thing I added was garlic. To the reviewer who claimed it had no flavor, either you are a terrible cook and messed up the recipe or your taste buds are off. If you know anything about cooking, you should know to taste and season along the cooking process. I loved this dish very much, thanks for a great recipe.

  14. I’m sorry. Made it last night and was unfortunately really disappointed. No flavor. Is it a misprint or does it really call for only 1/4 tsp of nutmeg & thyme? That’s not even enough to flavor HALF of this dish. The Sherry would have been really nice if I could actually taste it! I used 8 cloves of garlic too and added an onion…still, no flavor. I don’t know, I’m glad everyone else is enjoying it but I’m not happy. I’ll give it another try, but next time I will make sure to add more flavor.

  15. Oh WOW! We had this for Supper tonight. I was trying to use leftover turkey and this was delicious! My two-year-old went back for seconds. I didn’t have sherry, but I am sure that adds nicely to the rich flavor.

  16. I’m a little ashamed to admit that I’ve never made tetrazzini at home! Yikes – bad food blogger 🙂 haha This looks wonderful – and such a great way to re-purpose leftover chicken or turkey!

  17. This turkey tetrazzini looks incredible! Quick meals that you can make ahead of time are my favorite! Yup, – I’m with you – the peas and mushrooms are essential in here 🙂

  18. I was just thinking I needed to make chicken tetrazzini soon, and it’s so great with turkey, too! I made it last year with leftover Thanksgiving turkey. My stomach is now growling, and I gotta make this soon!

  19. This is taking me back to childhood! My mom used to make chicken tetrazzini all the time. I loved it of course, probably because it is so fun to say tetrazzini, felt like a big word when I was little. I love that you made your own sauce rather than buying canned. I bet that makes it taste much better.
