When you bake this pasta casserole, some of the sauce bakes into the pasta, the flavors marry and [!!BAM!!] something wonderful happens. You’ll know what I mean when you try it. Ridiculously good, easy to prepare, kid friendly, reheats well and freezer safe. P.S. you can further simplify this by using rotisserie chicken – You’re welcome ‘ma friends :).

This recipe can be done entirely using a dutch oven so it can go from the stove to the oven saving you some dishes. You can also bake it in a 13×9″ casserole dish, but whichever path you choose, the result will be a cheesy, creamy chicken pasta bake that will have your family refilling their bowls.

About the Ingredients:

  • We used thin spaghetti, but you can substitute with any kind of noodles you have on hand such as linguine or fettuccini pasta for your chicken tetrazzini casserole.
  • SHORTCUT: (what you will see in the video), you can use a rotisserie chicken and cut away enough chicken meat to get 4 cups of shredded chicken. Light or dark meat will work.
  • This recipe calls for low sodium chicken broth. Regular chicken broth is ok, but go easy on the salt and add more to taste when making the sauce.

For the Chicken Tetrazzini:

  • 12 oz thin spaghetti or linguine
  • 4 cups shredded rotisserie chicken *or cook 2 lbs chicken breast
  • 1 lb button mushrooms thickly sliced
  • 1 medium onion finely chopped
  • 3-4 garlic cloves minced
  • 2 Tbsp Olive Oil

For the Creamy Sauce:

  • 4 Tbsp unsalted butter
  • 1/3 cup all-purpose flour
  • 2 1/2 cups low sodium chicken broth
  • 1 Tbsp lemon juice
  • 1 1/2 cups half and half or sub with equal parts milk & heavy cream
  • 1 tsp sea salt or to taste
  • 1/4 tsp black pepper, freshly ground
  • 1/4 cup parsley, chopped, plus more to garnish
  • 1 1/2 cups shredded mozzarella cheese


  1. Preheat Oven to 350˚F. Cook pasta in a large pot of salted water until aldente according to package instructions then rinse to stop the cooking process, drain and set aside.
  2. Cut 4 cups of chicken meat from a rotisserie chicken and shred into bite-sized pieces and set aside.

  3. Place a large dutch oven or pot over medium/high heat. Add 2 Tbsp oil then add sliced mushrooms and sauté 3 min or until softened. Add diced onions and cook until onions are soft and golden, 5-7 min. Add minced garlic and sauté another 1-2 min until fragrant. Remove to the cutting board with chicken.

  4. In the same pot, melt 4 Tbsp butter and whisk in 1/3 cup flour until lightly golden (1 1/2 min). Add 2 1/2 cups chicken broth, 1 Tbsp lemon juice, 1 tsp salt, 1/4 tsp pepper and whisk until smooth. Add 1 1/2 cups half and half and bring to a simmer. Season sauce with more salt and pepper to taste.

  5. Return chicken, mushrooms, onions and pasta to the pot then sprinkle in 1/4 cup chopped fresh parsley and stir to combine. Sprinkle the top generously with shredded mozzarella, cover and bake at 350˚F for 30 min then remove lid and continue baking 15 min.**

Recipe Notes

*To cook your own chicken: in your dutch oven or pot, melt 1 Tbsp butter and 1 Tbsp oil over medium-high heat. Season 2 lbs chicken breasts with about 1/2 tsp salt and 1/4 tsp pepper. Once oil is hot, saute chicken until golden brown on both sides and cooked through (about 4 min per side). Remove to cutting board to cool then cut into bite-sized pieces.

**If baking in a 13x9 casserole dish, cover with foil and bake 25-30 minutes then bake uncovered an additional 10-15 min (it bakes 5-10 min faster in a casserole dish)
