Ingredients

This Turkey Tetrazzini starts with ingredients you probably already have on hand, especially if you’re fresh off Thanksgiving.

For the creamy sauce base — unsalted butter, all-purpose flour, chicken broth, whole milk, and heavy cream — you’ll want everything at room temperature so it blends smoothly without lumps.

For the add-ins — cremini mushrooms, shallots, garlic, fresh thyme, and dry sherry — these bring all that earthy, aromatic depth that makes this dish taste restaurant-fancy.

1 pound	cremini mushrooms, sliced
1 cup	chopped shallots or onion

2 cups	whole milk
1-1/2 cups	heavy cream
2-3 tablespoons	dry sherry
⅛ teaspoon	ground nutmeg
¾ cup	grated Parmigiano Reggiano
¾ cup	frozen peas

Tools You’ll Actually Use

• Large heavy-bottomed pot or Dutch oven
• 13×9-inch casserole dish (4.8-quart)
• Large pot for boiling pasta
• Whisk
• Wooden spoon or spatula
• Baking sheet (to catch any drips)
• Small mixing bowl (for breadcrumb topping)
• Colander

Step-by-Step Instructions

Let’s make this turkey tetrazzini recipe happen — it’s easier than you think.

Prep Your Workspace

Preheat your oven to 400°F and generously butter a 13×9-inch casserole dish. While you’re making the sauce, get a separate pot of salted water boiling for the pasta. Cook the linguine or spaghetti (snapped in half) just until al dente, then drain it well and set aside.

Build the Flavor Base

Melt 2 tablespoons of unsalted butter in your heavy-bottomed pot over medium-high heat until it’s foaming and gorgeous. Toss in the sliced cremini mushrooms with ½ teaspoon salt and ¼ teaspoon black pepper, then let them cook for about 5 minutes until all their liquid releases and mostly evaporates.

Add the chopped shallots or onion and cook for another 3-4 minutes until the mushrooms are getting golden and caramelized.

Stir in the finely chopped garlic and fresh thyme, cooking for just 1 minute until your kitchen smells incredible. Scoop this mushroom mixture out and set it aside.

Create the Creamy Sauce

In that same pot, melt the remaining 4 tablespoons of butter. Stir in the all-purpose flour and cook for 1-2 minutes to make a roux — this cooks out the raw flour taste. Slowly whisk in the chicken broth, whole milk, heavy cream, dry sherry, ground nutmeg, 1 teaspoon kosher salt, and ½ teaspoon black pepper.

Keep whisking until the sauce is smooth, glossy, and thick enough to coat the back of a spoon, about 5 minutes.

Bring It All Together

Whisk in ¾ cup of grated Parmigiano Reggiano until it’s completely melted and smooth. Take the pot off the heat and fold in your sautéed mushroom mixture, frozen peas, shredded turkey breast, and chopped Italian parsley. Taste and adjust the salt and pepper — remember, this needs to season all that pasta, so be generous.

Stir in your cooked pasta until everything’s evenly coated, then pour the whole gorgeous mess into your prepared casserole dish.

Top It Off

In a small bowl, mix together 1 tablespoon melted butter, Panko breadcrumbs, ¼ cup Parmesan, and ¼ teaspoon black pepper. Sprinkle this breadcrumb mixture evenly across the top of your Tetrazzini — don’t skip this part, because that crispy golden topping is half the magic.

Bake Until Bubbly

Set your casserole dish on a baking sheet (trust me, this catches any drips) and bake for 25 minutes, until the topping is golden and the sauce is bubbling around the edges. Keep an eye on those breadcrumbs around the 15-minute mark — if they’re browning too fast, loosely tent the dish with foil.

Let the Tetrazzini rest for a few minutes before serving. The sauce will thicken as it cools, making it easier to slice and serve. Garnish with fresh parsley and dig in while it’s hot.

Pro Tips & Gentle Guidance

These little tricks will take your turkey tetrazzini from good to absolutely phenomenal.

Use room-temperature dairy if you can — cold milk and cream take longer to incorporate and can make your sauce lumpy. If you forgot to pull them out ahead of time, no worries, just whisk more vigorously.

Don’t overcook your pasta during the initial boil. Al dente is key here because it’ll continue cooking in the oven. Mushy pasta makes for a mushy casserole, and nobody wants that.

Taste your sauce before baking and season generously. The pasta and turkey will absorb a lot of that flavor, so it should taste slightly over-seasoned on its own.

If you’re making this with store-bought rotisserie chicken instead of Thanksgiving turkey, it works beautifully — just shred about 3 cups’ worth of breast meat.

Quick Fixes for Turkey Tetrazzini

Problem: Sauce is too thick and gloppy If your sauce looks more like paste than cream, splash in a bit more chicken broth or milk, ¼ cup at a time, until it loosens up. The sauce should coat the pasta generously but still flow a little.

Problem: Breadcrumbs are burning before the casserole is done Tent the dish loosely with aluminum foil as soon as you notice the tops getting too dark. The casserole will still heat through perfectly underneath.

Problem: Sauce is too thin and watery This usually means the roux didn’t cook long enough or the sauce didn’t simmer enough before adding the pasta. Let it bubble away for a few more minutes until it thickens, or add another tablespoon of flour mixed with a bit of milk.

Problem: Tastes bland You probably under-salted — remember, you’re seasoning a lot of pasta and turkey. Add more salt and pepper, and maybe a squeeze of lemon juice to brighten everything up.

Variations & Adaptations

This baked pasta dish is super flexible, so feel free to make it your own.

Swap the turkey for rotisserie chicken, leftover pork, or even cooked shrimp if you’re feeling fancy. Keep the protein amount around 3 cups for the best ratio.

Make it gluten-free by using your favorite gluten-free pasta and swapping the flour for a gluten-free blend or cornstarch (use about 3 tablespoons).

For a lighter version, use half-and-half instead of heavy cream, or go half milk and half cream. It won’t be quite as rich, but it’ll still be delicious.

Add more veggies — chopped spinach, roasted red peppers, or sun-dried tomatoes all work beautifully here. Stir them in with the turkey and peas.

Try different cheese — Gruyère, white cheddar, or fontina would all be amazing instead of or in addition to the Parmesan.

For something totally different but equally indulgent, try my fried strawberry cheesecake sandwiches.

Serving, Storage & Reheating

This Turkey Tetrazzini is perfect for feeding a crowd or meal-prepping for the week ahead.

Serve it hot straight from the oven with a simple green salad and crusty bread to soak up that creamy sauce. A crisp white wine or even sparkling water with lemon feels fancy without any extra effort.

Store leftovers in an airtight container in the fridge for up to 4 days. The sauce will thicken considerably once chilled, but it reheats beautifully — just add a splash of milk or broth when reheating to loosen it back up.

Reheat individual portions in the microwave for 2-3 minutes, or warm the whole casserole covered in a 350°F oven for about 20 minutes until heated through. If you somehow manage not to eat this all at once, it actually tastes even better the next day after all those flavors have melded together.

Pair this with a pink lemonade cocktail for a fun dinner party vibe.

No-Waste Kitchen Magic

Got extra Turkey Tetrazzini or ingredients? Here’s how to use every last bit.

Leftover Tetrazzini makes an amazing filling for stuffed peppers or tomatoes — just hollow them out, stuff with the casserole, top with more cheese, and bake until tender.

Extra mushrooms? Slice and freeze them raw on a baking sheet, then transfer to a freezer bag. They’re perfect for throwing into soups, omelets, or sauces straight from frozen.

If you’ve got cooked pasta but no time to make the full recipe tonight, toss it with a little olive oil and store it in the fridge for up to 3 days. It’ll be ready to go when you are.

Day-old Tetrazzini can be formed into patties, coated in breadcrumbs, and pan-fried into crispy casserole cakes — kids go absolutely wild for these.

Save your Parmesan rinds in the freezer and toss them into soups or pasta water for extra umami flavor. They’ll keep for months and add so much depth.
