A classic Southern side dish, this creamy and cheesy squash casserole is filled with tender squash, sautéed onions, and a buttery cracker topping that will have everyone coming back for seconds!

Ingredients

Scale
  • 2 pounds yellow squash, sliced 1/4 inch thick (about 5 medium-sized squash)
  • 1/4 cup butter, divided
  • 1/2 cup diced onion
  • 1/2 teaspoon garlic powder
  • 3/4 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 cup sour cream
  • 1 large egg, beaten
  • 1 cup shredded cheddar cheese
  • 1/2 cup grated Parmesan cheese, divided
  • 1 cup butter crackers (such as Ritz), finely crushed (about 25 crackers)

Instructions

  • Sauté Onions and Squash:
    • In a large pan over medium heat, melt 1 tablespoon of butter. Add the diced onion and sauté for 7-8 minutes until soft and translucent.
    • Add the sliced squash and cook for 10-12 minutes, stirring frequently until the squash is soft and releases moisture.
  • Drain Excess Moisture:
    • Place a towel in a colander to prevent the squash from slipping through. Transfer the cooked squash and onions into the towel-lined colander.
    • Let it drain for at least 5 minutes, pressing out any extra moisture.
  • Prepare Squash Mixture:
    • In a large bowl, combine the drained squash and onions, garlic powder, salt, black pepper, sour cream, beaten egg, cheddar cheese, and 1/4 cup of the Parmesan cheese.
    • Stir until well combined.
  • Prepare Cracker Topping:
    • Melt the remaining 3 tablespoons of butter. In a small bowl, mix the melted butter, crushed crackers, and remaining 1/4 cup Parmesan cheese.
  • Assemble and Bake:
    • Scrape the squash mixture into a 1.5-quart baking dish (8×8 inches or similar). Sprinkle the cracker topping evenly over the top.
  • Bake:
    • Preheat your oven to 350°F. Bake the casserole for 25 minutes, or until golden and bubbly.

Notes

  • For a creamier texture, you can add an extra tablespoon of sour cream or use cream cheese instead of sour cream.
  • If you prefer a more pronounced cracker topping, increase the number of crackers.
  • Make ahead: Prepare the casserole and refrigerate it before baking. When ready, bake at 350°F for 30-35 minutes.
