This rich, creamy side with its crunchy topping would make a wonderful dish to take to summer potlucks and picnics or to pair up with a wide variety of entrees. Our taste testers loved the buttery flavor and dubbed it “comfort veggies”! Jennifer Wallace — Canal Winchester, Ohio

Thought it was very good. Used homemade bread crumbs with the melted butter for the topping instead of the cracker. Next time will add water chestnuts for an added crunch.

Loved this! Out of all the casseroles made this summer this was my favorite. It's even better the next day.

This is one of my favorites. My recipe calls for 2 lbs of squash. I usually use stuffing mix. Chopped red pepper really dresses it up. The last time I didn't have red pepper so I halved cherry tomatoes and along with green pepper. I will try the corn flakes next time.

I substituted chayote for the yellow squash and my family loved it! I will try adding some chicken next time.

This was tasty but it seemed like something was missing.

I loved this recipe. It turned out fabulous. I used a sharp cheddar but I am going to try it with Kraft Triple cheddar tonight. My daughter and grandson loved it too.

Teenagers love this! A good way to use the summer squash grown in the garden. I used a blend of whatever cheeses I had in the refrigerator.

Excellent! Remember since you are cooking the squash it will be soft but absolutely fabulous! My husband does not like casseroles but loved this! I added garlic to the recipe. Will make and share this one!

I thought this was great. I made it just the way the recipe called but I added diced cooked chicken and made it a meal.
