This tuna casserole is an updated version of a recipe handed down from my grandmother, Elizabeth Kelleher Daly so of course it uses potatoes as its starch. She actually called it California Chicken. I guess to a native Yankee, the joke was that in California, tuna is chicken.

I nearly passed this by because for some reason potatoes and tuna didn't sound that great. I love tuna though, so I thought I'd add this to my list of new attempts...(bein' used to noodles or biscuits instead of potatoes) :o). I have to say, I'm glad I made this. It took a little longer than the few minutes for the cream mixture to thicken, and you must be a speedy preparer, Janet, but in the end, it was very tasty, and my husband loved it, too! I walked my dog and came home to a lovely aroma in the house. I added a picture because it was worth it! Thanks for posting this, janet7th! I'll definitely make it again!


Very delicous my children loved it (2&3) I added more veggies red and green peppers,daikon, celery, garlic, onions, potatoes and carrots sliced in food processer but no peas. :) will cook again.

This was so simple to make and very enjoyable. The cracker topping was a nice touch.
