Best Southern Yellow Squash Casserole Recipe

This Southern Yellow Squash Casserole combines grated and sliced yellow squash cooked with sautéed onion and garlic, mixed with creamy ingredients like sour cream and canned soup, then layered with cheddar cheeses and bound with eggs. A crunchy topping made from crushed butter crackers, Parmesan, thyme, and melted butter adds texture after baking. The casserole is baked until the squash is tender and the crust is golden, making an indulgent vegetable side dish featuring distinctive Southern flavors.

Description

The recipe begins by softening onion and garlic in vegetable oil then steaming a combination of grated and sliced yellow squash until tender and its liquid has evaporated. This cooked squash is combined when slightly cooled with creamy elements—cream of chicken soup, sour cream, beaten eggs—and a blend of white cheddar and American cheese food for richness. The mixture is poured into a prepared baking dish and baked at 350°F to meld the flavors and set the filling.

While baking, a crunchy topping of crushed butter crackers mixed with Parmesan cheese, dried thyme, and melted real butter is added to introduce a crisp texture and herbaceous notes contrast with the creamy filling. The casserole offers a soft, creamy interior with flavorful bites from this topping. Selecting small fresh yellow squash and flavorful sharp cheeses enhances the dish's quality.

It pairs well as a comfort-style side dish especially alongside Southern or home-cooked meals, providing a satisfying way to enjoy summer squash with a cheesy and buttery crust.

Variations may include alternative crunchy crust toppings such as fried onions or different crackers. Using frozen chopped onion can save prep time. Gently crushing crackers inside their packaging is an efficient way to prepare topping crumbs. Seasoning blends like Old Bay or Italian herbs can be experimented with for different flavors.
