Tuna Mushroom Casserole Recipe

I love to serve this dressed-up version of a tuna casserole. The green beans add nice texture, color and flavor. The first time I made this dish, my uncle asked for seconds even though tuna casseroles are not usually his favorite. -Jone Furlong, Santa Rosa, California

This is how a tuna casserole is supposed to taste. Very delicious. Comfort food with a healthy kick. Love all the veggies in it.

I almost have this recipe memorized. I used to dislike tuna casserole very much but this one with the swiss cheese sauce, WOW! I actually crave this. I double the sauce and 1 1/2 times the noodles because I don't like it too dry, I also only put half of the tuna and am dying to try it with chicken but I don't know if it would be as good. Everyone love it. I also chop the mushrooms very tiny so my son doesn't even know that they're in there. (smiles) This is my most favorite recipe of all time. Try it!

I used sodium free chicken bouillon and left out the salt. It was very good that way.
