Notes
PRO Tips:
- You can also use 2 cups of cooked chicken in this recipe, either leftover chicken or rotisserie. The benefit of cooking fresh chicken in the pot is that it transfers more flavor into the sauce.
- Shred your own cheese from a block, it will melt better and give you much creamier results. Bagged shredded cheese contains cellulose which prevents it from melting as well in soups and sauces.
- Don't add the cheddar cheese when the base is very hot, or the dairy will separate and the consistency will be grainy. (This is outlined in the instructions as well.)
- I prefer to use thin spaghetti for this recipe but you can use regular, angel hair, or other types of pasta noodles if that's all you have.
Storage:
- Store in an airtight container and refrigerate for up to 3 days or freeze for up to 3 months. Note that the consistency of the sauce won't be exactly the same when reheated from frozen.
