If you’re wondering what to make with leftover turkey, this creamy pasta bake is always a winner. It’s rich, flavorful, and family-friendly—similar in comfort to classic casseroles but with an irresistible cheesy twist.

Why This Recipe Works

I’ll be real with you — I used to dread leftover turkey. It felt dry and boring no matter what I did with it.

Then I tried this.

Tender spaghetti. A velvety mushroom cream sauce. Juicy turkey folded right in. Then a thick blanket of parmesan and mozzarella melted over the top.

It changed everything.

What I love most is how forgiving this recipe is. You don’t need to measure perfectly. You don’t need to stress. Mix it, dump it in a dish, throw cheese on top, bake it. Done.

I’ve made this the day after Thanksgiving more times than I can count. My family now looks forward to it more than the actual turkey dinner. That says something.

What You’ll Need

Here’s a quick look at the ingredients and what they actually do:

Ingredient	Why It’s Here
Spaghetti (12 oz)	The base — soaks up all that creamy sauce
Cream of mushroom soup (2 cans)	Adds rich, savory depth without any extra work
Sour cream (1 cup)	Gives the sauce a smooth, tangy creaminess
Chicken broth (1 cup)	Loosens the sauce and adds extra flavor
Onion powder (½ tsp)	Quiet background flavor that ties it together
Garlic powder (½ tsp)	Just enough warmth without overpowering
Black pepper (to taste)	A little kick to balance the richness
Cooked turkey (2 cups)	The star — shredded or chopped both work great
Parmesan cheese (1 cup)	Salty, nutty, and melts into the top layer
Mozzarella cheese (2 cups)	That stretchy, gooey cheese pull we all love

Simple stuff. Nothing weird. Nothing you need to hunt down at a specialty store.

Tools You’ll Need

Nothing fancy here either:

• A large pot for boiling the pasta
• A big mixing bowl for the sauce
• A 9×13-inch baking dish
• A colander to drain the spaghetti
• A whisk or wooden spoon

That’s it. If your kitchen has these five things, you’re ready to go.

How to Make It Easy Turkey Tetrazzini

Step 1: Cook the Spaghetti

Bring a large pot of salted water to a boil. Cook your spaghetti according to the package directions — but pull it out before it’s fully soft.

Keep it al dente. It’ll keep cooking in the oven, and you don’t want mushy pasta.

Drain it and set it aside.

Step 2: Make the Sauce

Grab your large mixing bowl. Add:

• Both cans of cream of mushroom soup
• The sour cream
• The chicken broth
• Onion powder, garlic powder, and pepper

Stir it all together until it’s smooth. It should look thick and creamy — like a sauce that means business.

Step 3: Add the Turkey and Pasta

Toss in your cooked turkey and drained spaghetti.

Mix it all up until everything is coated in that sauce. Don’t be shy here — really get in there and toss it well.

Step 4: Load It Into the Baking Dish

Preheat your oven to 375°F (190°C).

Grease your 9×13-inch baking dish and pour the mixture in. Spread it out evenly so it cooks through properly.

Step 5: Add the Cheese

First, sprinkle the parmesan evenly over the top.

Then pile on the mozzarella.

Don’t hold back. This is a casserole. Cheese is the point.

Step 6: Bake It

Slide the dish into the oven — uncovered — and bake for 25 to 30 minutes.

You’re looking for:

• Hot and bubbly edges
• Melted, lightly golden cheese on top
• That smell that makes everyone wander into the kitchen asking “what’s cooking?”

Step 7: Let It Rest, Then Dig In

Pull it out of the oven and let it sit for 5 to 10 minutes before serving. This helps it set up so it doesn’t fall apart when you scoop it.

Then serve it up. Every bite is creamy, cheesy, and deeply satisfying.

Pro Tips (Don’t Skip These)

• Don’t overcook the pasta. Al dente going in means perfect texture coming out.
• Grate your own cheese. Pre-shredded cheese has coatings that stop it from melting properly. Freshly grated is worth the extra two minutes.
• Taste your sauce before adding the pasta. Depending on how salty your broth and turkey are, you might want a pinch of salt.
• Let it rest. Seriously. 5 to 10 minutes makes serving so much easier.

Swaps and Variations

This recipe is flexible. Here’s how I’ve changed it up over the years:

• No turkey? Use rotisserie chicken. Works just as well.
• Want veggies in there? Mushrooms, frozen peas, or a handful of spinach all fold in beautifully at Step 3.
• Watching calories? Swap in light sour cream. The sauce will be a little less rich, but still tasty.
• Extra cheesy? Add some sharp cheddar to the mix. No one will complain.
• Want a crunchy top? Mix a handful of breadcrumbs with a little melted butter and sprinkle it over the cheese before baking. Chef’s kiss.

What to Serve With It

This dish is rich and filling on its own. I like to keep the sides simple:

• Garlic bread or dinner rolls — great for scooping up extra sauce
• A crisp green salad — cuts through the richness perfectly
• Steamed broccoli or green beans — adds some color and balance to the plate

Storage and Leftovers

Good news — this reheats really well.

Storage Method	How Long	Notes
Fridge (airtight container)	3 to 4 days	Best way to store it
Microwave reheat	A few minutes	Add a splash of broth or milk if it thickens up
Oven reheat	15–20 min at 350°F	Keeps the top nice and slightly crisp
Freezer	Up to 2 months	Texture may change slightly after thawing
