Description

Southern Squash Casserole is a classic comfort dish made with tender yellow squash, onions, creamy cheese, and a buttery cracker topping. It’s rich, flavorful, and the perfect side for family gatherings, holidays, or Sunday dinners.


Ingredients

  • 5 medium yellow squash, sliced (about 6 cups)
  • 1 small onion, finely chopped
  • 2 tablespoons butter
  • 1 cup shredded cheddar cheese
  • 1/2 cup sour cream
  • 1/4 cup mayonnaise
  • 1 large egg, beaten
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 sleeve buttery crackers (such as Ritz), crushed
  • 2 tablespoons melted butter (for topping)


Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
  2. In a large skillet, melt 2 tablespoons of butter over medium heat. Add sliced squash and chopped onion, cooking for 8–10 minutes until tender. Drain any excess liquid and let cool slightly.
  3. In a large mixing bowl, combine sour cream, mayonnaise, egg, cheddar cheese, garlic powder, salt, and pepper. Stir in the cooked squash and onions until well combined.
  4. Pour the mixture into the prepared baking dish and spread evenly.
  5. In a small bowl, mix crushed crackers with melted butter. Sprinkle evenly over the casserole.
  6. Bake for 25–30 minutes, or until golden brown and bubbly.
  7. Let cool for a few minutes before serving warm.

Notes

  • For a lighter version, use Greek yogurt instead of sour cream.
  • Add a pinch of cayenne pepper for a subtle kick of heat.
  • You can substitute zucchini for part of the squash for extra color and flavor.
  • This casserole can be made ahead — cover and refrigerate before baking, then bake when ready to serve.
