Notes

I made this recipe with yukon gold potatoes which work well in soups and casseroles because they keep their shape and don't fall apart easily. If you prefer, you can also use red or white potatoes.

This recipe is a great way to use up cooked chicken breast but any cooked chicken will work, such as rotisserie chicken.

Make sure not to overcook potatoes and broccoli. You want to parboil them but not cook them completely or else they will turn mushy.

Shredded cheddar cheese can be swapped for other types of cheese such as monterey jack or gruyere. You can also use a cheese mix.
