This recipe goes back years, it is a family favorite that I still make to this day, and I have also make it using cooked chicken or cooked turkey in place of the tuna, is a easy basic casserole, but it has tons of flavor!

This recipe is excellent. I was afraid I lost the recipe, and looked on here but only found the ones with canned soup. I looked for it again, and found it, and I'm rating it so I know in the future which one was so great!! I used 2 % milk and omitted peppers, everyone raves when I make it. I also leave out the melted butter on top.

By far my favorite tuna noodle casserole recipe! I used green onions and didn't have celery, but added two cloves of garlic. I used peas instead of mushrooms and only had 2% milk which worked great! I topped with a little more cheese and crushed seasoned croutons. I made a 12oz bag of egg noodles but added only about 8oz of them and it was perfectly creamy... loved it! My youngest child says she wants leftovers for breakfast:)
