A creamy Turkey Tetrazzini recipe with mushrooms, peas, and a crunchy topping made with panko breadcrumbs and parmesan cheese. So good you'll be roasting two turkeys!
This easy Turkey Tetrazzini recipe is one of my very favorite ways to use up leftover Thanksgiving turkey meat. When leftovers can be transformed into an entirely new dish, I'm always on board. I'm also a sucker for a good topping, and the addition of grated parmesan is on point.
I love how customizable this recipe is, too. Add green chiles for some spice, use mushrooms or peas if you like or simply leave them out. Leftover green beans? Toss 'em in! No leftover turkey? Use a rotisserie chicken! It's all good (literally).

I'm not exaggerating in the slightest when I say that I look forward to Thanksgiving leftovers every year just so I can make this turkey tetrazzini. I usually serve it with any vegetable sides we have leftover from Thanksgiving dinner (usually Green Beans Almondine and/or a carrot souffle). And for dessert we almost always have some pumpkin pie cake or pumpkin tres leches cake left (and often both, since I usually get roped into making two desserts since everyone has their favorite).
Ingredients
Many turkey tetrazzini recipes call for canned mushroom soup. This isn't one of them. It's so simple and quick to make a homemade sauce and it will taste so much better!
- Pasta (spaghetti, linguine, or egg noodles all work well)
- Unsalted butter
- Onion
- Garlic
- All-purpose flour
- Chicken stock or broth
- Heavy cream
- Leftover shredded turkey
- Frozen peas
- Salt & pepper
- Panko breadcrumbs
- Grated parmesan cheese
- Fresh mushrooms (optional)
- Chopped parsley, for garnishing (optional)
Instructions
- Preheat your oven to 400°F and grease a 13x9-inch baking dish or a 2-quart casserole dish.
- Cook the pasta just until al dente according to the package directions, then drain it really well. You don't want any water thinning your sauce, so let it sit in the colander for a few minutes while you make the sauce.
- Next you'll melt some butter in a large skillet over medium heat. Add the chopped onion and cook it until it's soft and translucent, about 5 minutes (stir it occasionally). Stir in the garlic and cook another minute, stirring it frequently so the garlic doesn't burn.
- Now it's time to make the sauce. Sprinkle the flour over the onions and garlic, stirring constantly for about 1-2 minutes to cook out the raw flour taste. Slowly whisk in the chicken broth a little at a time, then the heavy cream, whisking until smooth between each addition. Let it come to a gentle simmer and keep cooking until it's slightly thickened, about 5 minutes. Season with salt and a few grinds of black pepper.
- Add the shredded turkey, peas, and the cooked pasta to the skillet. Toss everything together until the noodles are evenly coated in the sauce. Taste and adjust the seasoning at this step! This dish really pops as long as you season it enough.
- Now melt some butter in a small bowl (I use the microwave in 15-second increments, then whisk it once there are only a few small solid pieces of butter left). Stir in the panko breadcrumbs and grated parmesan until it's evenly combined.
- Pour the pasta mixture into that baking dish you greased in step 1, and spread it out evenly. Sprinkle the breadcrumb topping over the top.
- Bake your turkey tetrazzini for 30 minutes, or until the casserole is hot and bubbling and the topping is golden brown. Let it rest for 5-10 minutes before serving so the sauce can thicken.

Be sure to pay special attention when seasoning - even after I've seasoned each component and baked it, I typically add a little more salt and a lot of freshly ground black pepper to my own plate - it really brings out the flavor.
The other day I was busy (and therefore absentminded) and forgot to add it. I was thinking, "hmmmm...what's missing from this?" when I remembered I'd forgotten the extra seasoning. It's amazing what a difference the freshly ground black pepper makes!
Tips
- Don't overcook the pasta! Make sure to cook it just to al dente. It will continue to cook in the oven, and overcooked pasta can turn mushy.
- Drain the pasta really well. Even a little excess water can thin the sauce and make the tetrazzini soupy. I like to let it sit in the colander for a few minutes while I finish the sauce.
- Use freshly grated parmesan. It has a better flavor than the pre-grated kind, although that will certainly work if that's all you've got on hand.
- Taste and season as you go. Taste the sauce before adding the pasta and again before baking. It's the best way to make sure the flavors are balanced and that it's seasoned properly.
- Don't skip the panko-parmesan topping! It gets a little crispy and is such a nice contrast to the creamy sauce underneath.
- Try add-ins depending on what you've got. Sometimes I'll sauté fresh, sliced mushrooms with the onions if I've got some in the fridge. I've also added a can of green chiles to the sauce which was delicious! This recipe is forgiving and easy to customize based on what's in your fridge.
- Let it rest before serving. Giving the casserole 5-10 minutes to settle helps the sauce thicken.
- Double it up. If you have extra turkey, make two smaller casseroles. I like to make one for dinner and another to freeze for a busy night later.

Storage and Make-Ahead
Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 4 days. The sauce will thicken slightly as it cools, and it reheats well.
Reheating: Heat individual portions in the microwave, or reheat the entire casserole in the oven, covered with foil, at 350°F for about 20-25 minutes, until it's hot throughout.
Freezing: This dish freezes really well. You can freeze it before or after baking.
- Before baking: Follow the recipe instructions until just before baking. Place the tetrazzini in a freezer-safe dish, cover it tightly with foil, and freeze it for up to 3 months. Thaw in the refrigerator overnight before baking as directed in the recipe.
- After baking: Let it cool completely, then wrap it tightly and freeze. Reheat it directly from frozen in a 350°F oven for about 45 minutes, covered, until it's hot and bubbling.
Make-ahead: You can assemble the tetrazzini up to one day ahead, cover it tightly, and refrigerate. When you're ready to bake it, let it sit at room temperature for 20-30 minutes, then bake as directed in the recipe.
Meal prep: Divide into smaller baking dishes or oven-safe containers before freezing so you can thaw and reheat single servings for easy weeknight dinners. (Quick note: Just today (10/20/25) I ordered some Souper Cubes and this turkey tetrazzini will be perfect for them. I started following SimplySarahHart on TikTok after watching some of her freezer videos. I'll update once I've used them!)

I'll usually double the recipe and make two dishes, then freeze one for dinner on a night when I know we'll be busy. The recipe makes a lot by itself so if you don't have as many mouths to feed, make the recipe as written but use two 8x8 pans and freeze one.
Frequently Asked Questions
Can I make turkey tetrazzini with chicken instead?
Rotisserie chicken works perfectly and makes this an easy year-round dinner, not just during the Thanksgiving holiday.
Can I use a different pasta shape?
Spaghetti, linguine, or egg noodles work best, but short pasta like penne or rotini works too. Just be sure to cook it just to al dente and drain it well.
What if I don't have heavy cream?
Half-and-half or a mix of milk and cream will work in a pinch. The sauce won't be quite as rich, but it will still be creamy and delicious.
Can I add vegetables besides peas and mushrooms?
Green beans, broccoli florets, or even chopped spinach all work well. I often add leftover vegetables from Thanksgiving (it's a great way to clean out the fridge)! Just be sure you don't add too many additional ingredients or it won't be saucy enough.
Why did my sauce turn out too thin?
Most likely, the pasta wasn't drained completely or the sauce didn't simmer long enough to thicken before baking. It should coat the back of a spoon before you mix in the turkey and pasta.
Why did my topping get too dark?
Every oven runs a bit differently. If the topping starts to brown too quickly, loosely cover the dish with foil for the last 10 minutes of baking.
Can I make it without the breadcrumb topping?
You can, but I strongly recommend keeping it. The contrast between the crunchy top and creamy pasta is what makes this dish soooo good!
How can I make it lighter?
Use milk instead of cream, reduce the butter in the topping and when sautéing the onions and garlic, and add extra vegetables. The flavor will still be good, just not quite as rich.
What should I serve with turkey tetrazzini?
I usually just go with a fresh green salad or roasted vegetables. Garlic bread is always a hit, too! See below for a few recommendations. ⬇️

Notes
If adding mushrooms, add them with the onions and cook until their liquid has been released and evaporated. I usually add around 8-16 oz.
This recipe makes a lot, so you can make two 8x8 pans and freeze one for later if you like.
