A simple, creamy zucchini squash casserole that comforts and delights with just five ingredients. This easy, cozy dish is perfect for busy weeknights and offers a warm, cheesy, and fresh flavor.

Ingredients

Scale
  • 2 medium zucchinis, sliced
  • 2 medium yellow squashes, sliced
  • 1 cup sour cream
  • 1 cup shredded cheddar cheese (sharp or mild)
  • 1 cup crushed Ritz crackers
  • Salt and pepper to taste
  • 2 tablespoons melted butter (optional, for topping)
  • 1/2 teaspoon garlic powder (optional)
  • 1/2 teaspoon onion powder (optional)

Instructions

  1. Preheat the oven to 350°F (175°C).
  2. Wash and thinly slice the zucchinis and yellow squashes into roughly 1/8-inch thick rounds.
  3. In a medium bowl, mix sour cream, shredded cheddar cheese, salt, pepper, garlic powder, and onion powder until smooth and creamy.
  4. Gently fold the sliced zucchini and squash into the creamy mixture, coating evenly without crushing the slices.
  5. Spread the mixture evenly into a greased 9×13-inch baking dish.
  6. In a small bowl, combine crushed Ritz crackers with melted butter and stir well.
  7. Evenly sprinkle the buttery cracker crumbs over the zucchini mixture in the baking dish.
  8. Bake for 30-35 minutes until the top is golden brown and the casserole is bubbling around the edges.
  9. Let the casserole cool for about 5 minutes before serving.

Notes

Slice zucchini and squash uniformly about 1/8 inch thick for best texture. For a lighter version, substitute half the sour cream with plain Greek yogurt. Use crushed gluten-free crackers or panko for a gluten-free topping. To avoid burning the topping, cover loosely with foil if browning too fast. The casserole can be prepared ahead and refrigerated before baking, adding a few extra minutes to bake time if baking cold. Freeze unbaked casserole for up to 2 months; thaw overnight before baking.
