I've made this several times now and it is a favourite! I brown the onion and celery first, substitute the sour cream with yogurt and add 1/2 tsp each of dill, basil and pepper. Sometimes I will substitute the zucchini with a package of thawed spinach. I usually just mix everything (instead of layering) together. Read More

Hmmm...interesting. I had a little bit of a tough time getting passed the weird taste of the heated mayonnaise in this. It's a decent dish if you don't have cream of mushroom soup on hand to make the real deal. I might make this again but will leave out some of the mayo next time. Read More

I was looking for a tuna casserole that had something more than just noodles and tuna...and boy, did I find it!!! I've made this a hand full of times since finding the recipes...I add more zucchini than is called for...heck, I probably doubled the recipe for leftovers. It's a definite crowd-pleaser...served with warm crusty bread...it's a rainy day favorite! Read More

This recipe is alot like my own except I'd omit mustard and thyme. I also saute onion and celery until slightly tender.Any pasta will work and any cheese.I add peas and sliced black olives and a can of creamed soup and a little milk. Crush crackers and mix with a little melted butter for the topping. Read More

I was looking for an interesting tuna casserole recipe that didn't use mixed vegetables or condensed soup. This one called for zucchini which I don't usually make and it sounded good. Well it was delicious! My family went back for seconds. I will now be making this dish often! Read More

Great and definately not the norm. Changes I made: Added a bit of milk and walnut pieces. To help make this lowfat I substituted the montary jack with colby/montary jack that comes in 2% milk. The walnuts add yet another taste that blends perfectly. Easy quick and delicious. Read More

I made this last night for dinner. While searching receipes, this is the only one that didn't require a condensed soup, so I chose this one. I omitted the tomato and zucchini (didn't have any), added mushrooms and spinach. Used Dijon mustard (thats all I had). Seasoned to taste while in the mixing bowl. Added some Worcheschire sauce (copied that from another receipe). As other reviewers mentioned, it wasn't super creamy, but that didn't stop me from eating it. Yummy!! Will definitely make this again. Read More
