Layered Cheesy Tuna and Zucchini Casserole

"A family favorite! --- I would recommend to slice the zucchini fairly thick and you may want to add in some chopped green bell pepper also if desired, I have even substituted cooked chicken breast in place of tuna with great success, I like to combine both mozzarella and cheddar cheeses but of coarse one or the other may be used, I also add in 1 teaspoon garlic powder to the sour cream mixture."

  1. Really good! Used yellow onions instead of green. I did like the crunch of the veggies and the lack of cream soup. Also, I used greek yogurt instead of sour cream.
     
  2. Very good! I love a no cream of soup tuna casserole. I made this as directed but used cream for the milk and used the seasoned salt and garlic powder options. It might be because I'm pregnant but I think I prefer my tuna casseroles just with peas and onion...I wasn't loving the crunchy celery and zucchini flavors. Made for 1-2-3 hit wonders tag game.
     
  3. Loved this casserole! This is a creamy, cheesy dish that is pure comfort food! I used my last garden yellow squash in place of zucchini. And took Kitt's advise and added the garlic powder. Just delicious! Thanks Kitt! As usual a winner at my house!
     
  4. Found this while looking for something that used both tuna and zucchini. The ingredient list isn't full of weird things, and instead of using cream of celery soup, you pretty much make your own with the celery, sour cream, mayo and milk. This recipe did make plenty, but it will be great for leftovers. It is the best tuna casserole recipe I have made. We didn't use 4 cups of cheese, maybe 3 at most. Also left out the green onions and forgot about the tomatoes. But my kids loved it and it was easy enough to make, so I think we will see it again.
     
  5. This is really yummy! DH loved the addition of tomatoes, he even diced more for his plate. Both kids ate their entire serving, including zucchini, with no cajoling! The only change I made was to use penne pasta, as that's all I had. For my personal preference, next time I think I'd sautee the celery and onion for a minute or two to soften them up a little more, as they still had a little bite in them. I halved the recipe, and we still have plenty of leftovers - thanks, Kit, for a great one!
