Ingredients You’ll Need

Here’s what goes into this cozy fall meal recipe. You probably have half of it in your pantry already:

The Base

• 1 pound spaghetti – You can use linguine or fettuccine if that’s what you’ve got
• ½ cup unsalted butter + 2 tablespoons olive oil – For richness and a bit of depth
• 1 small onion, chopped – Doesn’t matter if it’s yellow or white
• 3 cloves garlic, minced – You know the drill
• ½ cup all-purpose flour – This is our thickener

The Sauce

• 8 oz cream cheese (room temp) – Makes it creamy with a little tang
• 3 cups low sodium chicken broth
• 2 cups milk – Whole or 2% works best
• 1 tsp Italian seasoning
• Salt and pepper to taste

The Stars

• 2 cups grated Parmesan cheese – Divided
• 4 cups cooked turkey, chopped – Rotisserie chicken works too

Optional add-ins:

• Frozen peas
• Mushrooms (sauté them with the onions)
• Chopped spinach

How to Make Turkey Tetrazzini (Step-by-Step)

Alrighty, tie that apron, crank up some music, and let’s go. This is gonna be fun—and you’re gonna crush it.

1. Cook Your Pasta

Bring a big ol’ pot of salted water to a boil. Toss in your spaghetti and cook it until it’s just al dente—like a little bite left in the middle. Drain it and let it cool. This is key if you want a saucy tetrazzini (and yes, you do want it saucy).

2. Start the Sauce

In a saucepan, melt the butter and olive oil over medium heat. Add your chopped onion and let it hang out for 5 minutes until it’s soft and slightly golden. Stir in the garlic and let that cook for another 30 seconds. Smells good already, right?

3. Make a Roux (Fancy Word for Sauce Starter)

Whisk in the flour. Let it cook for 2 minutes—you’re building flavor here, not just thickening. Slowly add in the chicken broth, milk, Italian seasoning, salt, and pepper. Keep whisking until it starts to bubble and thicken slightly.

4. Get Creamy with It

Add the cream cheese and 1½ cups of the Parmesan cheese. Stir until it all melts into a silky, creamy dream.

5. Mix It All Up

Toss in your turkey, then the spaghetti. Mix everything together—gently but thoroughly. You want every noodle coated in that glorious sauce.

6. Assemble & Bake

Transfer it all to a greased 9×13 casserole dish. Sprinkle the remaining ½ cup of Parmesan over the top. Bake at 350°F for 30–45 minutes, until it’s bubbly and the top is starting to get golden brown.

Pro tip: If you like it extra crispy on top, throw it under the broiler for 2–3 minutes at the end. Just don’t walk away. I’ve burned too many dinners that way. Learn from me.

Tips & Tricks (From My Kitchen to Yours)

• Cool your pasta before mixing it with the sauce. It soaks up less liquid that way, keeping your tetrazzini creamy—not dry
• Add frozen peas straight into the mix—no need to thaw. They’ll cook in the oven
• Use what you’ve got—this recipe works with leftover turkey, rotisserie chicken, or even some cooked sausage if that’s what’s in the fridge
• Make ahead? Yes please. Assemble it all, cover tightly with foil, and pop it in the fridge or freezer. Thaw overnight before baking

What to Serve With Turkey Tetrazzini

This dish is the star of the table, but if you want to serve up a full fall feast, try pairing it with:

• Garlic bread (because carbs on carbs = joy)
• Roasted Brussels sprouts
• A big green salad with apples and candied pecans
• A glass of white wine or a cozy apple cider mocktail

Storing & Reheating Leftovers

Let’s be honest, leftover tetrazzini might be even better the next day. Store it in the fridge (covered or in an airtight container) for up to 4 days. Or freeze it for up to 3 months.

Reheat in the oven at 350°F until warm and bubbly again. Or zap individual portions in the microwave.
