Ingredients
  

  • 4 cups yellow squash sliced 1 small onion, finely chopped 1 tablespoon butter 1 cup shredded cheddar cheese 1/2 cup sour cream 1/2 teaspoon salt 1/4 teaspoon black pepper 1 large egg, beaten 1 cup crushed Ritz crackers (for topping) 2 tablespoons melted butter (for topping)

Method
 

  1. Preheat your oven to 350°F (175°C).
  2. In a skillet, sauté the sliced squash and chopped onion in 1 tablespoon of butter over medium heat for 5 to 7 minutes, or until the vegetables are softened.
  3. Transfer the cooked squash mixture to a large mixing bowl. Add the shredded cheddar cheese, sour cream, salt, pepper, and beaten egg. Stir until everything is evenly combined.
  4. Pour the squash mixture into a greased 8x8-inch baking dish and spread evenly.
  5. In a small bowl, mix the crushed crackers with the melted butter. Sprinkle this buttery crumb topping evenly over the casserole.
  6. Bake for 25 to 30 minutes, or until the topping is golden and the casserole is bubbly.
  7.  
  8. Let cool for 5 minutes before serving.

Notes

  • This casserole works great with a mix of yellow squash and zucchini.
  • For extra flavor, add a pinch of garlic powder or a handful of chopped fresh herbs.
  • Make it ahead: Assemble the casserole up to a day in advance and refrigerate until ready to bake.
 
  • You can swap Ritz crackers with crushed cornflakes or panko breadcrumbs for a different topping texture.
