Layered Cheesy Tuna and Zucchini Casserole

Layered Cheesy Tuna and Zucchini Casserole created by Chipfo

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.

    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.

    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.

    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!
