What Is Turkey Tetrazzini
Turkey Tetrazzini is one of those cozy, old-school casseroles that turns leftover turkey into something everyone actually gets excited about. It’s made with pasta (usually spaghetti, but fettuccine, too), creamy sauce, mushrooms, and some recipes include plenty of cheese. Everything gets baked together until it’s hot and bubbly.
Ingredients For My Turkey Tetrazzini
- Fettuccine – Spaghetti works too.
- Olive oil – Feel free to use avocado or coconut oil.
- Butter – I prefer unsalted butter.
- Yellow onion – White onion is a good swap.
- Mushrooms – Creminis are my favorite. Canned mushrooms work too.
- Garlic – Fresh garlic is best, but garlic powder works too.
- All-purpose flour – You can use cornstarch instead.
- Broth – Use turkey, chicken, or veggie.
- Milk – Whole milk or 2% is great.
- Frozen peas and carrots – They can be canned, just rinse and drain them well.
- Salt and pepper – Kosher salt and freshly cracked black pepper are best for this.
- Turkey – Use Thanksgiving or Christmas leftovers, or a roast turkey breast.
Katerina’s Recipe Tips & Variations
- Make it spicy. Add cayenne pepper or red pepper flakes to taste for some heat.
- Use leftover sauce. Mix in alfredo sauce or bechamel leftovers into the pasta to reduce cooking time.
- Make it cheesy. Shred 1/4-1/2 cup parmesan cheese into the sauce or sprinkle it on top for some melty goodness.
- Use short pasta. Fusilli, bow tie, and penne are great swaps for fettuccine.
- Swap the protein. Leftover shredded rotisserie chicken or grilled shrimp are easy variations.
- Make it meatless. Double the veggies in the recipe and leave out the turkey for a vegetarian dinner.
Serving Suggestions
- Try my crisp, savory, and seriously delicious Brussels sprouts with bacon.
- Or go for roasted sweet potato wedges if you’re craving something a little sweet and cozy.
- Ham and bean soup is another comforting option, especially if you’ve got leftover ham.
- A bowl of roasted tomato soup adds rich, bold flavor to the meal.
- And if you’re in the mood for something fresh, my green goddess salad is always a hit around here!

- Make the slurry. Whisk the flour and broth until smooth in a small bowl. Add it to the pan.
- Add the veggies. Stir in the milk and remaining veggies. Season with salt and pepper.

How to Store & Reheat Leftovers
- Fridge: Place it in an airtight container for up to 5 days. This recipe isn’t freezer-friendly because the pasta will change texture when thawed, and the sauce will split.
- To reheat it: Microwave it for up to a minute or until warm. You can also heat it in a pot, with the lid on, over medium-high heat for 8-10 minutes. Stir occasionally.
Turkey tetrazzini is an old fashioned dish that people should make more often because it’s delicious. And that’s a great assortment of turkey recipes.
I don’t like turkey (I know, I’m strange) but I will so be making this with some leftover steak or salmon. Major yum!
I’m not crazy about turkey, either. I will only eat it if it’s swimming in gravy. ๐ Happy Thanksgiving, Laura! xo
