Tuna Mushroom Casserole Recipe

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 by far the best tuna noodle casserole I have ever had! I didn't have frozen green beans so I used a can of beans. Other than that I followed the recipe as written. This will be my go-to recipe in the future. Thanks for sharing!"

"This was good. I thought having the green beans mixed in would be weird , but it was fine. It fit in a 2 quart dish just fine."

"Followed recipe as written and while the casserole was good, it was an awful lot of work and not much better than "tuna helper" in a box."

"My husband grew up thinking that Tuna Noodle Casseroles were "icky", and back when he was growing up in the 50's and 60's, cooks just threw together some canned tuna, cream of mushroom soup, noodles and maybe some canned peas. No culinary art to those renditions at all.

He certainly eats this one, however!! I've cooked this version since it came out in the "Taste of Home" magazine many years ago! To make it even more upscale and updated, I have always used 2 FRESH tuna steaks, cut into a 1/2 " dice instead of canned tuna, and the tuna is cooked when the casserole goes in the oven, not beforehand. I also use canned chicken broth (1/2 C.) instead of the bouillon. Everything else in the recipe stays the same. It's so good to have some fresh veggies to add flavor to the sauce. My children have always eaten this one as well."

"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!"

"The tuna casserole recipe that my husband grew up with contains only tuna and pasta. I like this much better because it has other vegetables. Sometimes I mix it up by swapping the mushroom for green peas to accomodate everyone's taste."

"Delicious! Sometimes I substitute thyme and a little nutmeg for the dill for a different flavor. Have never bothered to bake it though..."
