If you need some comfort food goodness in your life, you can’t go wrong with this easy chicken tetrazzini recipe. It checks all those cozy comfort food boxes: pasta, creamy soup, sour cream, and cheese (3 different kinds!). And, of course, to make it a meal, we add in chicken and peas—you have to have your protein and veggies, too!

Chicken Tetrazzini Recipe

Although you can make chicken specifically for this recipe, I usually make a double-batch of chicken breasts (either Easy Baked Chicken Breasts or Air Fryer Chicken Breasts) and then we have half of them for dinner the first night, and then the second night, I use the leftovers to make chicken tetrazzini. Another option is to buy a rotisserie chicken, which makes things even easier!

You can assemble this in advance and then pop it in the oven when it’s dinnertime. Chicken tetrazzini is also a great option to bring to a potluck! It’s the kind of recipe that everyone loves, and when served with a bunch of other casseroles and sides, it can definitely feed a crowd!

How to Make Chicken Tetrazzini

1. Prepare

Preheat your oven to 350ºF and spray a large baking dish with cooking spray.

2. Assemble

In a large mixing bowl, stir together the soups, milk, peas, salt, pepper, and chicken. Then, stir in the spaghetti and transfer it to the prepared baking dish. Top with the cheeses and cover with foil.

3. Bake

Bake the chicken tetrazzini for 30 minutes, or until the cheese is melted and bubbly.

Hint: If you like, you can take the foil off at the end of cooking time and broil the casserole for a few minutes, until the top is lightly browned.

How to Store and Reheat Leftover Chicken Tetrazzini

You can cover the baking dish or transfer the leftovers to an airtight storage container and refrigerate for 3 to 4 days. Reheat leftovers in a 350ºF oven or in the microwave until warmed through. You can also freeze leftover chicken tetrazzini for up to 2 months.
