This is a very good dish! I used white fish instead of tuna and it turned out very tasty. It is quick and easy to prepare.

Surprised more people have not tried this recipe. Quick and easy with great results for a tuna fan! Not a big tuna fan myself, but my family loves it. I added seasonings according to their taste buds. Here are the extras I used to make a one dish meal. * I sauted the onions slightly with a dab of butter before placing with the potatoes. * Added just a touch of Ms. Dash with salt and pepper to taste. * Brocolli and sliced mushrooms to give more variety for a one dish meal. However, any vegetable or add in could be used to acheive the one dish meal, use your favorites. Try using Cream of Chicken -or- Campbell's makes a Cream of Chicken and Mushroom together. They have many varieties available now. * Instead of just pouring the sauce mixture over the top before baking. I tosssed it lightly among all the ingredients. Thank You Sara for the recipe. Even my picky 6 year old liked it. He will only eat tuna salad, but tried this and ate seconds. I will be trying this again, maybe mixing it up for other meats, add ins etc...

This could be good with more seasoning and a little less onion. May try again.

This recipe was very bland,I have leftovers and I think I will reheat with some grated pepper cheeze mixed in.

we added some left over seasoned salmon, and it added some a lot of good flavor. we also added some fresh mushrooms, i'd recommend that if you like them. make sure to add the flour before you add the milk, the sauce thickens very slowly, since it took about half an hour, so i would make the sauce first. the casserole turned out great, but there wasn't a lot of spice to it. next time i'll try using dijon mustard to see if that gives it a little extra kick.

Although we do not care for spicy foods, my family and I found this recipe a bit bland. (Seasoned salt helped.) However, since there are so few recipes for potatoes and tuna, it was about the best we could do.

I made this according to the directions and didn't like the texture and the taste. I ended up just making quick hot dogs for my family instead.
