Fill the pan. Pour the pasta and sauce into an un-greased glass baking dish. Sprinkle a layer of shredded mozzarella cheese over top, followed by grated parmesan.
Bake. Pop the chicken Tetrazzini into a preheated oven to bake until the casserole is bubbly and the cheese is nice and browned around the edges.
Garnish and serve. Finally, garnish your chicken Tetrazzini with a light sprinkle of chopped parsley if you’d like, and serve!
Can I Make Chicken Tetrazzini Casserole Ahead of Time?
Chicken Tetrazzini is a great make ahead meal option! Make the dish a day ahead, and wrap the unbaked casserole tightly in plastic wrap to store in the fridge until you’re ready to bake it. You can also make and then freeze Tetrazzini – see my instructions below!
What Kind of Chicken To Use
How you cook the chicken is up to you. Here are some easy options:
Rotisserie chicken – Pick up a pre-cooked rotisserie chicken at the grocery store and shred it to use in this chicken tetrazzini. One whole chicken will be enough if you use the white and dark meat, or two chickens if you just use the breast.
Boil – You can quickly boil the chicken while the pasta for this recipe cooks in a separate pot. Check that the chicken breasts reach an internal temperature of 165°F, and then chop them up to use in the recipe.
Leftovers – This is a great way to use up leftover chicken! Or, if you’re making chicken for dinner, and have plans to make chicken tetrazzini later, make extras and then chop and freeze them until you’re ready to use them.
Tips for Success
Use Ready Made Chicken: One whole store bought, pre-cooked chicken is often enough for this recipe. Or, if you’re already making another easy chicken dinner, save and freeze any extra chicken so it’s ready to go for your next chicken Tetrazzini!
Multitask While Cooking: You can also quickly boil uncooked chicken breasts for this recipe, in a separate pot, at the same time that you’re boiling the pasta. Just be sure the chicken breasts reach an internal temperature of 165°F before cutting them up.
