Hearty Tuna Casserole

Here's a jazzed-up version of Mom's tuna casserole that's sure to be comfort food for the whole family! Jan Heshelman of Bloomfield, Indiana adds pizzazz to the traditional dish with mustard, sour cream, thyme and zucchini. "I found this recipe in a magazine," says Jan. "It is one of the few dishes with zucchini that my husband will eat."

    This was really good! I just substituted 2 C frozen mixed veggies for zucchini, and red bell pepper for tomatoes. And cheddar jack cheese for mozzarella. I think they meant 2 tablespoons of prepare mustard. And I did 1/2 c sour cream and 1/2 cup of mayonnaise. I didn't care for the dried thyme and will be using dried parsley next time. It was a great dinner to throw together on a cold winter night! Thank you Taste of Home!!

    This is the healthiest tuna casserole that I've ever made. I substituted grated carrot for the zucchini and added some chopped fresh spinach. It was delicious.

    I made this for my husband and I and he really like it. I like the fact it had zucchini, I have not seen that before and really appreciated that. I would definitely make this again.

    glad to see a healthy version of this classic..used Hellman's Balsamic Mayo and Dijon mustard in it and it really was much better tasting while still keeping calories under control.

    I cut the recipe in half. I used pasta shells instead of noodles, chopped fresh spinach instead of zucchini, added chopped mushrooms, chopped red bell pepper. Since I cut the sauce ingredients in half I was afraid it would be dry so I poured 1/4 cup chicken broth over the whole dish before I baked it. I didn't layer the cheese. I waited until the casserole was cooked through and then added 1/4 cheese on top and let it melt. Turned out really tasty. Would definitely make again.

    I like the idea of adding zucchini to this recipe to add some veggies to the dish...it was very tasty... we enjoyed it. I served it w/a baked tomato dish.
