Ingredients

Scale
  • 4 medium zucchinis, shredded
  • 1 cup shredded sharp cheddar cheese
  • ½ cup shredded mozzarella cheese
  • 1 cup crushed Ritz crackers
  • 4 tablespoons butter, melted
  • ½ small yellow onion, finely diced
  • 2 cloves garlic, minced
  • 2 large eggs, beaten
  • ½ cup whole milk or 2%
  • 2 tablespoons all-purpose flour
  • Salt and freshly ground black pepper, to taste
  • 1 tablespoon chopped fresh parsley or thyme (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13 inch casserole dish lightly with butter or cooking spray.
  2. Shred the zucchini using a box grater or food processor. Place the shredded zucchini in a clean kitchen towel or paper towels and squeeze out as much moisture as possible.
  3. Heat 1 tablespoon of butter in a skillet over medium heat. Add the diced onion and cook for 3-4 minutes until softened and translucent. Add minced garlic and sauté for 30 seconds until fragrant. Remove from heat and let cool slightly.
  4. In a large bowl, whisk together the eggs, milk, flour, salt, and pepper until smooth. Stir in the cooled onion and garlic mixture, shredded zucchini, and shredded cheeses. Fold in fresh herbs if using.
  5. Pour the zucchini mixture evenly into the prepared casserole dish and spread gently with a spatula.
  6. In a small bowl, combine crushed Ritz crackers with melted butter, mixing until crumbs are evenly coated and slightly clumpy.
  7. Sprinkle the buttery Ritz cracker mixture evenly over the zucchini layer, pressing down lightly to help it stick.
  8. Bake in the preheated oven for 35-40 minutes until the top is golden brown and crispy and the casserole is set but still creamy inside.
  9. Let the casserole rest for about 10 minutes before serving to firm up and make cutting easier.

Notes

Drain zucchini thoroughly to avoid soggy casserole. Use sharp cheddar for best flavor. Melted butter on Ritz crackers is key for a crispy topping. If topping browns too quickly, tent with foil. Let casserole rest before serving for easier slicing. For gluten-free, substitute flour and crackers accordingly. For dairy-free, use plant-based alternatives and flax egg.
