A comforting, cheesy casserole featuring zucchini and yellow squash with a crispy buttery Ritz cracker topping, perfect for cozy dinners.

Ingredients

Scale
  • 3 medium zucchinis, sliced thinly
  • 3 medium yellow squash, sliced thinly
  • 1 teaspoon salt
  • 4 tablespoons unsalted butter, melted
  • 2 cups sharp cheddar cheese, shredded
  • ½ cup Parmesan cheese, grated
  • ½ cup mayonnaise
  • ½ cup sour cream
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Freshly ground black pepper, to taste
  • 1½ cups Ritz crackers, crushed

Instructions

  1. Slice 3 medium zucchinis and 3 yellow squash into thin rounds about ¼ inch thick. Place in a colander and sprinkle with 1 teaspoon salt. Let sit 15-20 minutes to draw out moisture.
  2. Press the squash with paper towels or a clean kitchen towel to squeeze out as much liquid as possible.
  3. Preheat oven to 350°F (175°C).
  4. In a large bowl, combine dried squash slices with 2 cups shredded sharp cheddar, ½ cup grated Parmesan, ½ cup mayonnaise, ½ cup sour cream, 1 teaspoon garlic powder, 1 teaspoon onion powder, and freshly ground black pepper to taste. Stir gently until evenly coated.
  5. Spread the squash mixture evenly in a greased 9×13-inch casserole dish.
  6. Crush about 1½ cups Ritz crackers until fine but not powdery. Mix with 4 tablespoons melted unsalted butter until crumbs are moistened and hold together loosely.
  7. Sprinkle the buttery cracker crumbs evenly over the squash mixture.
  8. Bake in the preheated oven for 30-35 minutes until bubbly and golden brown on top.
  9. Let the casserole cool for 5-10 minutes before serving.

Notes

Salting and draining the squash is crucial to avoid a watery casserole. Use freshly shredded cheese for better melting. Crush crackers finely but not to dust for the best topping texture. Tent with foil if topping browns too quickly. Let casserole rest before serving for cleaner slices.
