What is Creamy Turkey Tetrazzini?

Creamy Turkey Tetrazzini is a baked pasta casserole made with cooked turkey, pasta (usually spaghetti or short pasta), mushrooms, onions, and a creamy sauce. Everything gets tossed together, topped with cheese and breadcrumbs, and baked until bubbly and golden brown. It’s named after Italian opera singer Luisa Tetrazzini, though funnily enough, it’s totally American in flavor and spirit.

This dish originally gained traction as a clever way to use leftover turkey—especially around the holidays—and has since earned its spot as a beloved comfort food. It’s cozy, creamy, and just indulgent enough to make you forget how tired you are from your day. It’s also super flexible. Don’t have mushrooms? Skip ’em. Only have rotini? Toss it in. It’s forgiving, unfussy, and downright delicious.

Reasons to Try Creamy Turkey Tetrazzini

First of all, Creamy Turkey Tetrazzini is a time-saving miracle for busy folks (looking at you, multitasking moms and late-night meal preppers). You don’t need fancy ingredients or complicated steps. Leftover turkey becomes the star, which means you’re also cutting back on food waste. Win-win. Second, it hits all the right textures—tender pasta, creamy sauce, and that crunchy baked top.

It’s like the casserole version of your favorite cozy blanket. Third? Picky eaters. Somehow, even mushroom skeptics have been known to go in for seconds when everything’s coated in cheesy, creamy goodness. And lastly, it’s a crowd-pleaser. Whether you’re feeding your family of five or showing up to a potluck, this dish disappears fast.

Ingredients Needed to Make Creamy Turkey Tetrazzini

• 3 cups cooked turkey, shredded or cubed
• 8 oz spaghetti or short pasta (penne or rotini work great)
• 1 cup mushrooms, sliced
• 1 medium onion, finely chopped
• 3 cloves garlic, minced
• 2 cups low-sodium chicken broth
• 1 cup heavy cream
• 1 cup grated Parmesan or mozzarella cheese (or a mix!)
• 1/2 cup panko breadcrumbs
• 2 tbsp olive oil or butter

Instructions to Make Creamy Turkey Tetrazzini

If you’ve ever stared at leftover turkey and wondered, “Now what?”, this step-by-step guide will walk you through how to turn that forgotten bird into a bubbling, creamy dream of a casserole. These instructions break down each part of the process to help you nail Creamy Turkey Tetrazzini from start to finish—no guesswork, no stress.

Step 1: Boil the Pasta Just Until Al Dente

Start by bringing a large pot of salted water to a boil. Salted water is key—it’s your first chance to season the pasta from the inside out. Add 8 oz of spaghetti or your pasta of choice (penne or rotini both work great) and cook until just al dente—firm to the bite. Don’t overcook it; your pasta will continue to soften in the oven later. Once it’s ready, drain it and give it a quick toss in a little olive oil to keep it from sticking while you prep the rest.

Step 2: Sauté the Vegetables for Depth of Flavor

Grab a large skillet and heat 2 tablespoons of olive oil or butter over medium heat. Once it’s shimmering (or melted), add 1 finely chopped medium onion and 1 cup of sliced mushrooms. Sauté them for about 6–8 minutes, stirring occasionally, until the onion is soft and translucent and the mushrooms have released their moisture and browned a bit.
Add in 3 cloves of minced garlic and cook for just 30 seconds—garlic burns quickly, and you just want it fragrant. This step builds the base of your creamy sauce and gives the casserole that rich, homemade flavor.

Step 3: Create the Creamy Sauce Step by Step

To the veggie mixture, slowly pour in 2 cups of low-sodium chicken broth and 1 cup of heavy cream. Stir everything well, scraping up any bits stuck to the pan (they’re flavor gold!). Bring the mixture to a gentle simmer—bubbling, not boiling—and let it cook for about 5 minutes until it thickens slightly.
If you like a little extra depth, you can stir in a splash of dry white wine here. It’s optional, but it gives the sauce a subtle brightness. Want to use milk instead of cream? Here’s a great article on creamy ingredient swaps you can check out.

Step 4: Add the Cooked Turkey and Pasta

Once the sauce is ready, add in 3 cups of cooked turkey (shredded or cubed) and your cooked pasta. Stir gently until everything is evenly coated in the sauce. It should look rich and creamy, with every noodle and turkey bite happily soaking it in.
If your turkey feels a bit dry, consider adding a tablespoon or two of broth right to the meat before mixing—it brings it back to life.
No turkey on hand? Shredded rotisserie chicken works perfectly too.

Step 5: Transfer to a Baking Dish and Add the Toppings

Grease a 9×13-inch baking dish (a light coating of olive oil or butter will do) and pour in your creamy pasta mixture. Spread it evenly with a spatula.
Now, sprinkle 1 cup of grated Parmesan or mozzarella over the top. Want the best of both worlds? Go half and half!
Then, add a generous layer of 1/2 cup panko breadcrumbs. This is what gives the casserole that beautiful golden, crunchy top after baking. You can mix a little olive oil or melted butter into the breadcrumbs for an even crispier crust.

Step 6: Bake Until Golden and Bubbly

Slide the baking dish into a preheated oven at 350°F (175°C) and bake for 25–30 minutes. You’re looking for a lightly browned top and sauce bubbling around the edges.
Don’t rush this—this step lets all the flavors marry, and the top layer turns gloriously golden.
Let it rest for 5–10 minutes after baking. This allows everything to set up just a bit and makes serving much easier. (Hot, cheesy noodles fresh out of the oven are no joke—don’t burn your tongue!)

What to Serve with Creamy Turkey Tetrazzini

This dish is rich and filling, so light sides work best. A crisp green salad with a tangy vinaigrette cuts the richness beautifully. Think arugula with lemon dressing or a classic Caesar if you’re feeling fancy. Roasted veggies—like asparagus or Brussels sprouts—are also a great option and can roast right alongside your casserole. Need something a little heartier? Try some crusty bread or garlic knots to help scoop up every last bit of creamy sauce. For a cozy meal combo, pair it with Creamy Roasted Garlic Cauliflower Soup—perfect for colder nights or when your soul needs a warm-up.

Key Tips for Making Creamy Turkey Tetrazzini

Don’t overcook your pasta—remember it’ll keep cooking in the oven. If you’re using turkey breast, moisten it with a splash of broth before adding so it doesn’t dry out. Want extra flavor? Add a dash of white wine to the sauce while it simmers. For the topping, don’t skip the panko. It gives the dish that irresistible golden crunch. No turkey? Rotisserie chicken totally works. Got picky kids? Blend the sauce if mushrooms are a hard pass—they’ll never know. Also, if you’re making this ahead of time, assemble everything and refrigerate—just wait to add the topping until right before baking.

Storage and Reheating Tips for Creamy Turkey Tetrazzini

Store any leftovers in an airtight container in the fridge for up to 4 days. To reheat, pop individual portions in the microwave for about 2–3 minutes (cover with a damp paper towel to keep it moist). For larger amounts, cover the baking dish with foil and reheat in a 350°F oven for about 20 minutes. If it looks a little dry, stir in a splash of broth or milk. You can also freeze the whole unbaked casserole. Wrap it tightly and freeze for up to 2 months. When ready to bake, thaw overnight in the fridge and add 5–10 minutes to the baking time.
