Good way to use up that garden zucchini! The key to this recipe is to sqeeze the excess moisture from the zucchini and onion, before you mix with the rest of the ingredients. I used sour cream as a substitute for the buttermilk, and used Colby Jack cheese, because it is what I had on hand. I made mine gluten -free by using the new Gluten-free Bisquick Mix.I finished mine off with slivered almonds before baking. I like a little crunch. Delish!

I was very disappointed in this one. Perhaps I did something wrong, but I tried it twice and it was gooey both times, even though the sides and top (and even the bottom) got REAL brown. It tasted underdone, but couldn't have been since it baked the full hour and would have burned if longer. Could it need an egg in the batter?

WOW!! This recipes is a gooey mess, but a delicious one! I added some Mrs. Dash & a little grated cheese. Next time, I'll try adding a few more veggies & make it in a bigger dish. Excellent taste!

Talk about Grandma's comfort food YUMMMY! The house smelled great and the taste rewarded us!! Ok I vary things according to what I have on hand so... I DICED the mix of yellow squash and zucchini and had to use the sour cream variation suggested by someone else. I had NO RUNNY-NESS but maybe because I diced the squash or cooked a few minutes longer. I also added ground cooked chicken to the mixture. I found I needed salt but would not add it until eating and I think next time, the addition of a 1/2 cup of SHARP cheddar would make this dish PURE HEAVEN!! Can ya tell I liked it???

My daughter made a similar recipe to this for Thanksgiving. It was fabulous and she shared the secret with me. To keep it from getting mushy, squeeze all the fluid from the zucchini before baking. It will be perfect every time.

I would add very small cut mushrooms and 1/3 cup of chicken broth for consistency and flavor.

This was great! I ran out of parmesan so I added in some chopped fresh mozzarella in tiny cubes. I also added 1 egg and a pinch of nutmeg.
