Onion and cheddar cheese perk up the rich flavor of summer squash in this comforting casserole from Katherine Metz, Jacksonville, Florida (with husband Chuck, at right). A crispy cornflake-crumb topping adds a little crunch.

This was delicious! I'm new to squash recipes and this one won me over. I will be making this one again!

My family really enjoys this. I also use crackers instead of cornflakes as a topping

Very Good! I will definitely be making this again. I doubled the recipe and substituted the mayo for sour cream, used brown sugar and replaced the cornflakes with crackers. Everyone loved it! :-D

I thought this was really good. I made it all summer long and decided to make it again tonight for dinner. Love it .... THANKS.

Making it for the second time in less than a week! My family loved it. I was able to adapt it for my dairy allergic kids by swapping out the cheddar for soy cheese. Great way to use up the overabundance of summer squash!
