About
Sundays would never be the same without this dish being included and passed around her table. Grandma's Squash Casserole was a staple at all of our weekly meals growing up, and we always looked forward to it! When some fresh-from-the-garden squash is sliced and joined with a seasoned, creamy cheddar and Swiss cheese sauce, topped with even more cheese (parmesan this time) and a crushed buttery cracker crust, you've got yourself a Southern side staple that everyone loves.
