A crispy, cheesy casserole featuring shredded zucchini, fresh corn, and a buttery Ritz cracker topping, perfect for summer dinners and gatherings.

Ingredients

Scale
  • 3 medium zucchinis, shredded (about 3 cups)
  • 1 cup fresh corn kernels (cut from 2 ears)
  • 1½ cups sharp cheddar cheese, shredded
  • ½ cup mozzarella cheese, shredded
  • 1 cup Ritz crackers, crushed
  • 4 tablespoons butter, melted
  • ½ cup sour cream
  • ¼ cup mayonnaise
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and pepper, to taste
  • ¼ cup Parmesan cheese, grated (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
  2. Shred the zucchinis using a box grater or food processor. Place the shredded zucchini in a clean kitchen towel or cheesecloth and squeeze out excess moisture.
  3. In a large bowl, combine the shredded zucchini, fresh corn kernels, sharp cheddar, and mozzarella cheese.
  4. Stir in sour cream and mayonnaise until evenly mixed.
  5. Add garlic powder, onion powder, salt, and pepper to taste. Mix gently but thoroughly.
  6. Crush the Ritz crackers finely using a food processor or by placing them in a resealable bag and rolling with a rolling pin.
  7. In a small bowl, combine the crushed crackers, melted butter, and grated Parmesan cheese (if using). Mix until crumbs are evenly coated and clumpy.
  8. Transfer the zucchini and corn mixture into the greased baking dish and smooth the top with a spatula.
  9. Sprinkle the Ritz topping evenly over the casserole.
  10. Bake for 30-35 minutes, or until the topping is golden brown and crispy and the casserole is bubbling around the edges.
  11. Let the casserole rest for 5-10 minutes before serving to firm up and meld flavors.

Notes

Squeeze out excess moisture from zucchini to prevent sogginess. Use freshly shredded cheese for better melting. If topping browns too quickly, tent with foil halfway through baking. For gluten-free, substitute Ritz crackers with gluten-free buttery crackers. For a lighter version, replace mayonnaise with Greek yogurt.
