Why You’ll Love This Recipe

Simple and Quick

This recipe is designed to be fast and efficient. From start to finish, you only need about 25 minutes. No need to pre-cook the pasta or make a separate sauce. Everything happens in one pot, cutting down on time and dishes.

Perfect for Leftovers

Got extra turkey from the holidays? This is one of the best ways to use it up. It's a great change from turkey soup or sandwiches and brings new life to your leftovers.

Family-Friendly and Comforting

It’s got that nostalgic, creamy, cheesy goodness that even picky eaters will love. Plus, the peas add a little burst of color and sweetness that balance out the savory richness.

Rich in Flavor, Creamy in Texture

This One Pot Turkey Tetrazzini is silky, savory, and just the right amount of indulgent. The pasta soaks up all the creamy broth, and the final touch of Parmesan adds that irresistible salty umami hit.

Customizable for Any Diet

You can easily adapt this recipe for different dietary needs. Use gluten-free pasta, switch to plant-based milk and dairy-free cheese, or skip the meat and use veggie broth for a vegetarian version.

Ingredients and Substitutions

What You’ll Need

• 1 tablespoon canola oil
• 1 cup white mushrooms, thinly sliced
• ½ medium onion, finely diced
• 1 teaspoon minced garlic
• 1 teaspoon salt
• ½ teaspoon dried thyme
• ½ teaspoon dried parsley
• ¼ teaspoon black pepper
• 1½ cups low-sodium chicken broth
• 2 cups milk or heavy cream
• 340 grams spaghetti, broken in half
• 2 cups cooked turkey or chicken, chopped
• 1 cup frozen peas
• ½ cup grated Parmesan cheese

Ingredient Notes

For the best flavor, use freshly grated Parmesan. Pre-shredded cheese often contains anti-caking agents that can make the sauce grainy. White mushrooms give a mild earthiness, but you can also use cremini or baby bellas for a deeper flavor. Whole milk works perfectly, but if you want a more luxurious sauce, go with heavy cream.

Substitutions to Make It Work for You

• Swap turkey with rotisserie chicken or even leftover ham
• Use vegetable broth to make the dish vegetarian
• Try different vegetables like spinach, chopped asparagus, or broccoli
• Use penne, fettuccine, or rotini instead of spaghetti (adjust cook time as needed)
• Want extra protein? Stir in some white beans or top with crispy bacon bits

Step-by-Step Instructions

1. Heat the oil in a large, deep skillet or Dutch oven over medium-high heat. Add the sliced mushrooms and diced onion. Cook for about 3 to 4 minutes, until the mushrooms are browned and the onions have softened.
2. Stir in the garlic, salt, thyme, parsley, and black pepper. Let it cook for another minute until fragrant.

3. Pour in the chicken broth and use a wooden spoon to scrape up any browned bits on the bottom of the pan.
4. Stir in the milk or cream and bring the mixture to a gentle simmer.

5. Add the broken spaghetti, stirring so the noodles are well-coated and submerged. Cover and cook for 10 to 15 minutes, stirring occasionally to prevent sticking. Cook until the pasta is tender and most of the liquid is absorbed.
6. Stir in the chopped cooked turkey, frozen peas, and Parmesan cheese. Cover again and let everything sit for 3 to 5 minutes to allow the flavors to come together.

7. Serve warm with extra Parmesan on top if desired.

Expert Tips and Tricks

Best Practices

• Stir often during cooking to prevent the pasta from sticking to the bottom of the pot.
• Let the dish sit for a few minutes after cooking to allow the sauce to thicken naturally.
• Break your spaghetti in half before adding it to the pot. This helps it cook evenly and fit more easily in the pan.

Common Mistakes to Avoid

• If your pasta is still dry but not yet cooked, simply add a splash more broth and continue cooking.
• If your pasta is cooked but the sauce is too thin, remove the lid and let it simmer uncovered for a few minutes. You can also stir in a cornstarch slurry if needed.
• Don’t add the cheese too early or at too high of a heat. This can cause it to clump or separate.

Time-Saving Hacks

• Use pre-sliced mushrooms and pre-chopped onions from the store
• Make it with rotisserie chicken or pre-cooked turkey
• Cook once, eat twice — this dish reheats beautifully and makes great leftovers

Serving Suggestions

What to Serve with Turkey Tetrazzini

Even though this is a full meal in one pot, here are a few ideas to round it out:

• A crisp green salad with balsamic vinaigrette
• Garlic bread or soft dinner rolls
• Roasted green beans or steamed broccoli

Presentation Tips

Scoop the pasta into shallow bowls and garnish with extra Parmesan or fresh parsley. You could even top with crushed buttery crackers or toasted breadcrumbs for a bit of crunch.

Best Beverage Pairings

• A chilled glass of white wine like Chardonnay or Sauvignon Blanc
• Sparkling apple cider for a festive non-alcoholic option
• Light herbal tea for a cozy finish to the evening

Storage and Reheating

How to Store Leftovers

Let the dish cool completely, then transfer to an airtight container.

• Freeze for up to 3 months (just note that the texture of pasta changes slightly after freezing)

How to Reheat Without Losing Quality

• In the microwave: Heat on medium in 1-minute intervals, stirring between each
• On the stovetop: Add a splash of broth or milk and reheat over low heat, stirring gently
• In the oven: Place in a covered baking dish and warm at 350°F for about 15 to 20 minutes
