I made this for a recent potluck and it was creamy, cheesy and delicious. The cornflake topping makes it an attractive dish and adds a nice crunch.

Good casserole! I doubled the recipe, except for the sugar and salt, and used a heaping cup of cheese. Didn't have cornflakes, so I used butter crackers. Definitely worth a try, especially if you have an abundance of summer squash to use up!

Made this recipe with summer squash and zucchini. Added some minced garlic and used panko because I did not have corn flakes. I placed the onion and squash in a large measuring cup along with 2 tablespoons of water. Covered and vented it and microwaved it for 5 minutes. Drained it and patted it dry. I wanted a lighter dish so I skipped the egg. Baked it according to directions. I came out deliciously hot and bubbly. Loved it. Want to try the technique with cauliflower and maybe carrots!!!!

Easy and cheap to make. Several friends asked for the recipe. Added a little parmesan.

Yum! I cut up 9 small yellow squash (approx. 5-6" long) that amounted to approx. 8 c. Used 4 eggs and 1 c. mayo. I didn't have the recipe in front of me and forgot the onion and sugar, but it was just fine without it. Approx. 1 c. of cheese. Added a couple dashes of an herb blend. Didn't have cornflakes so crushed some croutons on top. It was very good!!

I have been regularly making this recipe since it was first published. Many times I have quadrupled the portions and brought it to family get togethers. Everyone loves it. Best squash casserole recipe I've found. The only thing I do different is crush New York Texas Toast garlic and butter croutons for the topping.

This was only ok. Maybe I just don't like summer squash?
