- 1 cup sour cream or Greek yogurt: Adds tanginess and creaminess without weighing the dish down.
- 1/2 cup milk or broth: Lightens the sauce just enough, helping it coat the pasta perfectly.
- 1/2 tsp salt: Enhances all the flavors without overpowering them.

How to Make Turkey Tetrazzini with Spinach Recipe
Step 1: Sauté Aromatics
Start by melting butter in a large skillet over medium heat. Toss in the chopped onion and sauté until it’s soft and translucent, coaxing out its natural sweetness. Then, add the minced garlic and cook for just about a minute until fragrant. These aromatic veggies form the flavor foundation that makes this dish so irresistible.
Step 2: Combine Base Ingredients
Next, stir in the shredded turkey, chopped spinach, cream of mushroom soup, sour cream (or Greek yogurt), and milk or broth. Season with salt, black pepper, and garlic powder. Mix everything until the sauce is smooth and the spinach wilts gently, marrying all those flavors into a creamy, comforting sauce.
Step 3: Mix with Pasta and Cheese
In a large bowl, combine your cooked pasta with the creamy turkey and spinach mixture. Then fold in the shredded mozzarella and half of the Parmesan cheese. This step ensures every strand of pasta is luxuriously coated with that cheesy, savory goodness we all want in a perfect tetrazzini.
Step 4: Bake to Perfection
Transfer the mixture into a greased 9×13 inch baking dish. Sprinkle the remaining Parmesan cheese over the top, and if you like, add a layer of breadcrumbs for extra crunch. Bake the dish at 375°F (190°C) for 25 to 30 minutes until it’s bubbly and the top turns a gorgeous golden brown. The smell filling your kitchen will be absolute heaven!
Step 5: Serve and Enjoy
Once out of the oven, let the casserole cool slightly. Sprinkle with freshly chopped parsley for a splash of color and freshness. Serve warm and watch as everyone digs in and comes back for seconds of this delightful Turkey Tetrazzini with Spinach Recipe.

Make Ahead and Storage
Storing Leftovers

Freezing
You can freeze this casserole before baking by placing it in a freezer-safe dish and wrapping it well. It keeps well frozen for up to 2 months. When you’re ready to enjoy, thaw overnight in the fridge before baking as directed for a comforting meal anytime.
Reheating
Reheat leftovers in the oven at 350°F (175°C) covered with foil to prevent drying out, until warmed through. For a quicker option, microwave individual servings on medium power until hot, stirring halfway for even heating.
FAQs
Can I use chicken instead of turkey?
Absolutely! This Turkey Tetrazzini with Spinach Recipe works equally well with shredded cooked chicken, making it a versatile dish perfect for using up whatever poultry you have on hand.
Is there a dairy-free version of this recipe?
Yes, you can swap the butter for olive oil, use dairy-free sour cream alternatives, and choose a non-dairy milk. There are also plant-based cheeses that melt nicely. This way, you keep all the creamy texture without the dairy.
Can I make this recipe gluten-free?
Definitely. Just use gluten-free pasta and ensure that your cream of mushroom soup is gluten-free or make your own sauce from scratch to avoid any gluten-containing thickeners.
What can I substitute for cream of mushroom soup?
If you prefer homemade, mix sautéed mushrooms with a simple roux-based cream sauce or use cream of chicken soup for a slightly different but equally delicious flavor.
How do I keep the spinach from getting soggy?
Fresh spinach wilts quickly once mixed into the hot sauce, so add it at the right time and avoid overcooking during baking. The brief wilting in the sauce ensures it stays tender and vibrant rather than soggy.

This Turkey Tetrazzini with Spinach Recipe is such a fantastic way to create a comforting meal that’s packed with flavor, protein, and goodness.
