Southern Squash Casserole is a comforting baked dish made with tender yellow squash, onions, eggs, sour cream, and cheddar cheese, all topped with a buttery cracker crust. It’s creamy, cheesy, and a Southern classic perfect for family gatherings or potlucks.

Ingredients

  • 2 lbs yellow squash, sliced
  • 1 medium yellow onion, finely chopped
  • 3 tbsp butter
  • 2 large eggs
  • 1/2 cup sour cream or mayonnaise
  • 1 1/2 cups shredded cheddar cheese
  • 1 tsp salt
  • 1/2 tsp black pepper
  • 1/2 tsp garlic powder (optional)
  • 1 1/2 cups crushed buttery crackers (such as Ritz)
  • 2 tbsp melted butter or olive oil (for topping)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.
  2. In a skillet, melt butter over medium heat. Add onions and cook until softened.
  3. Add sliced squash and sauté 10–15 minutes until tender and most moisture evaporates. Let cool slightly.
  4. In a bowl, whisk eggs, sour cream (or mayonnaise), salt, pepper, and garlic powder if using.
  5. Stir in cheddar cheese, then fold in cooked squash and onions.
  6. Transfer mixture to prepared baking dish and spread evenly.
  7. Mix crushed crackers with melted butter or olive oil, then sprinkle over casserole.
  8. Bake 30–35 minutes until top is golden and casserole is bubbly.
  9. Cool for 5 minutes before serving.

Notes

  • Cook squash thoroughly to remove excess liquid and avoid a watery casserole.
  • Sharp cheddar gives the best flavor, but other cheeses like Gruyère or Monterey Jack work well.
  • To prepare ahead, assemble without topping and refrigerate; add topping before baking.
  • Reheat leftovers in oven to crisp topping again, or broil briefly if needed.
