A cozy and satisfying yellow squash casserole featuring tender squash and a golden, buttery cracker topping. Perfect for weeknights and gatherings, this dish combines creamy texture with a crunchy finish.

Ingredients

Scale
  • 4 cups sliced yellow squash (about 45 medium squash)
  • 1 medium onion, finely chopped
  • 4 tablespoons butter, melted
  • 1 cup sharp cheddar cheese, shredded
  • 1 can cream of mushroom soup
  • 1 large egg, beaten
  • Salt and pepper to taste
  • 1 1/2 cups buttery crackers, crushed (such as Ritz crackers)
  • 1/4 cup milk

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch casserole dish with butter or non-stick spray.
  2. Wash the yellow squash, cut off the ends, and slice into about 1/4-inch thick rounds or half-moons.
  3. In a large skillet, melt 2 tablespoons of butter over medium heat. Add the chopped onion and sauté for 3-4 minutes until softened and translucent.
  4. Add the sliced squash to the skillet and cook for 5-7 minutes, stirring occasionally, until tender but not mushy. Season lightly with salt and pepper. Remove from heat and let cool slightly.
  5. In a large bowl, combine the cooked squash and onions with cream of mushroom soup, beaten egg, shredded cheddar cheese, milk, and remaining 2 tablespoons melted butter. Stir gently until well incorporated. Season with additional salt and pepper to taste.
  6. Crush the buttery crackers until coarse crumbs. Mix the crushed crackers with about 2 tablespoons melted butter.
  7. Pour the squash mixture into the prepared casserole dish and smooth the top. Evenly sprinkle the buttery cracker topping over the surface.
  8. Bake in the preheated oven for 30-35 minutes, until the topping is golden brown and the casserole bubbles gently around the edges.
  9. Remove from oven and let the casserole cool for 5-10 minutes before serving.

Notes

If the cracker topping browns too quickly, tent the casserole loosely with foil halfway through baking. Drain excess liquid from cooked squash to prevent sogginess. Start seasoning lightly as cheese and soup add saltiness. Let casserole rest before serving for easier slicing. For gluten-free, use gluten-free crackers and soup. Vegan adaptations include plant-based cheese, vegan butter, and dairy-free soup alternatives.
