To make this creamy chicken tetrazzini recipe you’ll need:
- 6 ounces spaghetti
- 5 tablespoons butter, divided
- 3 large cloves garlic
- 8 ounces mushrooms, sliced
- 1 cup frozen baby English peas, thawed
- 3 cups cooked chicken, chopped
- 3 tablespoons all purpose flour
- 2 cups fat free, low sodium chicken broth
- ¾ cup heavy cream
- ¼ cup dry white wine
- 1 cup of shredded cheese
- ½ teaspoon kosher salt
- ¼ teaspoon freshly ground cracked black pepper
- ½ cup grated Parmesan cheese

How to make this creamy chicken tetrazzini recipe
Start by preheating your oven to 350ºF (180ºC).
Make the pasta
- For 6 servings of chicken tetrazzini, I used 6 ounces of spaghetti.
- That is less than you would normally cook for 6 servings but I like to use less pasta in a dish like this, since there are already lots of other calories with the butter, cheese and heavy cream.
- Cook your pasta according to package directions.
Cook the chicken and mushrooms
- While your pasta is boiling, melt 3 tablespoons of butter a sauté pan over medium heat.
- Add the mushrooms and garlic, and cook until browned (3-5 minutes).
- Add the chicken to the pan and toss well to coated it.
- Remove the chicken and mushroom mixture and let it rest on a platter while you prepare the delicious sauce. It’s important for the chicken to soak up the flavor of the garlic and butter for a while.

Make the tetrazzini sauce
- Melt the remaining 2 tablespoons of butter in the saucepan.
- Stir the flour into the melted butter.
- Slowly add the chicken broth and wine, whisking to combine.
- Increase the heat to medium high and bring the sauce to a simmer.
- Cook for 2 minutes, then stir in the shredded cheese and thawed peas, stirring well.
- When the sauce starts to simmer, reduce the heat to medium. Add the cream and let it cook on low, stirring constantly for 3 minutes. The sauce will thicken slightly as it cooks.
- Season it to taste with salt and pepper.
Tip: The cheese that I chose for the sauce is a Cabot reduced fat cheese. It has less calories but a lot of flavor and cooks well in a dish like this.

Cook the creamy chicken tetrazzini pasta casserole
- Put the cooked pasta, chicken mushroom mixture, and the sauce into a 9 x 13 inch baking dish. Stir everything so it’s mixed well.
- Sprinkle Parmesan cheese over the casserole.
- Bake it in the preheated oven for about 20 minutes until it’s bubbly and the cheese is sort of crusty and browned.

Can you believe something so luscious is made so easily? Why used canned sauces when you can make THIS in just a few steps and in about a half hour? It is rich, creamy, so incredibly tasty.
Perfect for any special occasion because you can do most of it ahead of time and just cook that last 20 minutes before serving.

Add a tossed salad or some garlic bread and prepare for your family to be impressed! The flavor of the sauce is amazing.
This chicken tetrazzini sauce is NOTHING like the ones I have made using canned soup. The butter and cream take it to another level. Seriously, take my word for it, you will love this dish.
