This easy broccoli chicken tetrazzini casserole is a great way to use up leftover chicken or turkey. Poached chicken can also be used if no precooked meat is on hand.

This recipe for low carb chicken tetrazzini casserole uses spaghetti squash instead of regular pasta. Like most of the other hard shelled winter squash, spaghetti squash is harvested in the early fall. We eat a lot of winter squash at this time of the year because it is so abundant and widely available fresh in the markets during the fall season.

Tetrazzini usually has mushrooms in it, but I left them out in this recipe. Mushrooms are low in carbs so they could added if desired.

I chose to add a bag of broccoli instead so I could make this a one dish meal since it contains both meat and vegetable. Tetrazzini is a great casserole recipe for using up leftover chicken or turkey because it requires a couple cups of diced cooked poultry.

I didn’t have any leftover meat so I poached some chicken breasts to use. Like roasting, poaching keeps the meat juicy and doesn’t sear the edges like pan frying. If you are looking for a recipe to use up some Thanksgiving turkey, this one is well suited for it.

The parmesan sprinkled on top of the tetrazzini casserole becomes a bit crusted and brown at the end of baking.

Additional grated parmesan can be sprinkled on top of each serving if desired. The creamy parmesan sauce goes well with the chicken and broccoli.

I may be making this super easy chicken tetrazzini casserole dish again after Thanksgiving to use up any leftover turkey meat.
