If you love a rich and creamy chicken dinner, you might also enjoy this simple recipe for creamy garlic chicken.

It takes me right back to my grandma’s kitchen. The sound of the oven door closing, the steam rising from the casserole dish. It was pure, simple comfort on a plate.
If you’re looking for a creamy bake that uses simple ingredients, you’ve found it. This is the traditional way, no fancy stuff needed. Let’s make a memory together.

The Story Behind This Classic Recipe
This dish has a funny little history. It’s named for an Italian opera star, Luisa Tetrazzini, from the early 1900s. They say chefs in San Francisco created it in her honor.
But in my family, it’s just “that spaghetti bake.” My grandma made it every Sunday after church. It was her go-to for feeding a crowd without any fuss.
It became the perfect way to use up turkey leftovers after the holidays, too. That creamy, savory sauce makes everything taste wonderful. It’s a story of making the most of what you have.
What Makes This the *Traditional* Way
Some recipes try to change things up. I think the old way is the best way. The magic is in its humble, pantry-friendly parts.
A true, classic Tetrazzini uses a simple creamy sauce built from scratch or with a can of cream of mushroom soup. It’s not about being gourmet. It’s about being reliable and deeply satisfying. For another fantastic creamy pasta dish with a different flavor profile, try this creamy chicken ranch pasta with beef bacon.
The pasta is always spaghetti or linguine, baked until the top is golden. That mix of creamy interior and crispy topping is non-negotiable. That’s the heart of the dish.

The Classic Ingredients (No Fancy Stuff!)
Gathering these ingredients is half the comfort. You probably have most of them already. Here’s what you’ll need for the real deal.
- 1 lb spaghetti or linguine
- 4 cups cooked chicken or turkey, shredded or cubed
- 8 oz mushrooms, sliced
- 1 medium onion, finely chopped
- 2 cloves garlic, minced
- 1/4 cup all-purpose flour
- 4 tablespoons butter
- 2 cups chicken broth
- 1 (10.5 oz) can cream of mushroom soup
- 1 cup whole milk or half-and-half
- 1 cup grated Parmesan cheese, divided
- 1/2 cup sour cream
- 1 cup frozen peas (optional, but classic)
- Salt and black pepper to taste
- 1/2 cup breadcrumbs or crushed crackers (for topping)
How to Make It Just Like Grandma Did
Don’t let the steps fool you. This is a simple, one-pan sauce situation. Just follow along and you’ll have a masterpiece.
- First, heat your oven to 375°F (190°C). Grease a 9×13 inch casserole dish well.
- Cook the spaghetti according to package directions until just al dente. Drain it and set it aside.
- While the pasta cooks, melt the butter in a large pot or Dutch oven over medium heat. Add the onions and mushrooms. Cook them until they’re soft and the mushrooms have released their liquid.
- Stir in the garlic and cook for one more minute until it’s fragrant. Sprinkle the flour over everything. Stir and cook for 2 minutes to get rid of the raw flour taste.
- Slowly pour in the chicken broth, whisking constantly to avoid lumps. Then whisk in the cream of mushroom soup and the milk. Let it simmer until it thickens nicely.
- Take the pot off the heat. Stir in 3/4 cup of the Parmesan cheese and all of the sour cream. Add the cooked chicken, peas (if using), and the drained spaghetti. Fold it all together until every noodle is coated.
- Pour the whole mixture into your prepared casserole dish. In a small bowl, mix the breadcrumbs with the remaining 1/4 cup of Parmesan. Sprinkle this over the top evenly.
- Bake for 30-40 minutes. You want it bubbly around the edges and the top to be a beautiful, golden brown. Let it sit for 10 minutes before serving. This helps it set perfectly.
My Tips for Perfecting This Classic
A couple of small tricks can make a big difference. They’re the little things my grandma always did.
First, undercook your pasta by a minute or two. It will finish cooking in the oven. This keeps it from getting mushy in the final bake.
Second, let your sauce thicken well on the stove. It should coat the back of a spoon. A thick sauce means a creamy bake, not a soupy one.
Finally, don’t skip the rest time after baking. Those 10 minutes let the flavors settle and make it so much easier to serve.
How to Store and Enjoy Later
This dish is a champion for make-ahead meals. You can assemble it completely, cover it, and keep it in the fridge for up to a day before baking.
Leftovers keep beautifully. Just cover the casserole dish with foil or transfer portions to airtight containers. They’ll last 3-4 days in the refrigerator.
To reheat, I like to warm individual servings in the microwave. For a larger portion, cover it with foil and bake at 350°F until heated through. This helps keep the topping from burning.

Your Questions About This Classic Recipe
Here are answers to a couple of common questions I get about this family favorite.
Can I use fresh mushrooms instead of the soup?
You absolutely can! The canned soup is the classic, easy route. For a from-scratch version, use an extra 8 oz of mushrooms and a bit more flour and milk to build your sauce. It’s delicious both ways.
What’s the best pasta to use?
Spaghetti or linguine are traditional and hold the sauce wonderfully. But any long pasta like fettuccine works great. The key is to break the long strands in half before boiling for easier serving.
Can I freeze Chicken Tetrazzini?
Yes, it freezes very well. Assemble the casserole but don’t bake it. Wrap it tightly in plastic wrap and foil. Freeze for up to 2 months. Thaw in the fridge overnight before baking as directed. You may need to add a few extra minutes to the bake time.
I hope this recipe finds its way to your family table. I hope it becomes part of your own story, just like it is in mine.
