Either cooked chicken breast or shredded/cubed rotisserie chicken will work here. This is a good recipe to use up leftover chicken.
We opted for ziti pasta, but you can use your favorite type of pasta for this casserole. It would be great with spaghetti, penne, rigatoni, or mostaccioli as well.
½ cup of hot sauce gives the casserole a nice kick, with that classic buffalo taste. It’s not too spicy and you can add more or drizzle extra sauce over the top to up the spice level. Likewise, if you want just a hint of buffalo flavor without the spice, I would reduce it to ¼ cup. We used Frank's red hot sauce.
You can use cream of chicken soup in place of the cream of celery. Do not combine the condensed soup with milk or water.
