Chicken Tetrazzini is one of those meals that brings the whole family to the table. It is incredibly cozy, creamy, and filling, making it the perfect choice for a busy weeknight when you really need some comfort food.

I love using a rotisserie chicken to make this come together quickly. If you want to make it extra golden and delicious on top, just pop it under the broiler for a minute or two before you take it out of the oven.

🧺 Ingredients

12 ounces spaghetti
3 tablespoons butter
1 small onion, diced
8 ounces mushrooms, sliced
3 tablespoons all purpose flour
2 cups chicken broth
1 cup heavy cream
2 cups cooked chicken, shredded
1/2 cup grated parmesan cheese
1 cup shredded mozzarella cheese
1/2 teaspoon garlic powder
Salt and pepper to taste

👩‍🍳Instructions

1
Preheat your oven to 375 degrees Fahrenheit and grease a large baking dish.
2
Cook the spaghetti in a large pot of salted boiling water according to the package directions, then drain it well.
3
Melt the butter in a large skillet over medium heat. Add the onion and mushrooms and cook until they are soft and golden.
4
Stir in the flour and cook for one minute, then slowly whisk in the chicken broth and heavy cream until the sauce thickens.
5
Add the cooked chicken, garlic powder, salt, pepper, and parmesan cheese to the skillet and stir until well combined.
6
Add the cooked pasta to the skillet and toss everything together so the sauce coats every strand of spaghetti.
7
Transfer the mixture to your prepared baking dish and sprinkle the mozzarella cheese over the top.
8
Bake for 20 minutes or until the sauce is bubbly and the cheese is melted and lightly browned.

💡 Tips

Store any leftovers in an airtight container in the fridge for up to three days. This dish reheats beautifully in the oven or microwave, but you might want to add a splash of broth if it seems a bit dry after chilling. It is wonderful served with a side of steamed broccoli or a fresh green salad.
