📜 A Little History
Southern Squash Casserole grew popular in mid-20th-century American kitchens, when casseroles became a staple for feeding families economically and deliciously. Yellow squash was abundant in backyard gardens, making this dish a natural favorite.
Over time, every household added its own twist — extra cheese, breadcrumbs instead of crackers, or even bacon — but the heart of the recipe stayed the same: simple vegetables transformed into rich comfort food.
🧬 Formation of Flavor
This casserole works because of contrast:
- Soft squash → creamy base
- Sharp cheddar → savory depth
- Tangy sour cream & mayo → richness
- Buttery crackers → crunchy topping
Together, they create that signature Southern balance: creamy inside, crispy on top.
