    Used rice instead of the thick noodles, and two cans tuna, extra can cheese soup, too.

    Love it but must confess I did not use reduced fat cheese or soup. The fresh mushrooms and pimentos all add to its great flavor. New favorite!

    Best tuna casserole I have ever made...and maybe the best I have ever eaten. Made it exactly as recipe instructed and it was indeed DELIGHTFUL! I wouldn’t change a thing.

    This was pretty good, got good reviews from my picky husband and my 5 year old. I salted the pasta water and added a few extra spices like garlic and onion powder so it was not bland for me. I also threw in some thawed frozen corn I had leftover from a soup recipe and topped it with crushed black pepper triscuits because I didn't have corn flakes.

    Creamy and satisfying recipe. Only two things I did differently were I substituted chopped sun dried tomatoes instead of pimentos since it was what I had on hand and added a half cup of chopped broccoli to mixture. We had not made this in ages, and we liked this a lot.

    I liked this recipe for tuna casserole. I substituted 4oz can sliced mushrooms for the fresh mushrooms just to save some time. It was still very good! I will likely make this recipe again!

    I've been searching for the perfect tuna noodle casserole...this wasn't perfect...I'm still looking...but overall this was pretty good and until I find the perfection I am looking for I would probably make this again
