I love recipes that turn vegetables into comfort food. Squash and zucchini casseroles are very popular but you rarely see corn added to them. I don’t know why because it’s a fabulous flavor combination. I love the sweetness that the corn adds.

A combination of mayonnaise, sour cream, and melted butter make this casserole wonderfully creamy. Some eggs and crushed crackers are added to the casserole to give it more substance.

I use all cheddar cheese, but a combination of cheddar cheese and mozzarella or Parmesan cheese would be equally delicious. There’s also sweet onion added for even more flavor.

It is important to pre-cook the squash, zucchini, and onion or else it will be crunchy and lacking in flavor in the finished casserole dish. I briefly simmer them in some chicken broth because it helps add flavor. You could just steam them or saute them in some butter or oil until crisp-tender. You don’t want them super soft because they will continue to cook in the oven.

If you have a bounty of zucchini or squash on your hands, give this cheesy casserole a try. You won’t be disappointed.
