🥘 Ingredients and Notes
(Find the complete recipe at the end of this post.)

For the Pasta – Shells work great for this leftover chicken recipe, but you can also use the tubular rigatoni, like what we use in our best rigatoni mac and cheese with bacon in it.
Cream Soup – Like our Creamy Garlic Mushroom Meatballs, you can also use cream of mushroom or cream of celery soup in this recipe.
For the Cheese – Use whatever you have on hand. Parmesan, cheddar, and mozzarella all work for this casserole.
For the Milk – 2% or whole milk works best for this casserole. Anything less takes away from the creaminess of it.
Variations and Substitutions
- Use whatever kind of leftover poultry that you have on hand.
- Rotisserie chicken from Costco.
- Leftover barbecued chicken from the grill
- oven-roasted turkey tenderloin
- Leftover Thanksgiving turkey meat
- Use your favorite cheese in this leftover chicken recipe, or whatever you have on hand.
- Mozzarella cheese works great for a mild and light flavor.
- Cheddar cheese will add a little more savory flavor to this leftover casserole.
- Parmesan cheese will give it a bit of an Italian flair.
- To make it extra creamy, substitute the milk with heavy cream or half-and-half.
