Common Mistakes to Avoid

Avoiding common mistakes can help you create the perfect Quick Baked Zucchini Parmesan Casserole. Here are some points to keep in mind:

  • Over-salting the zucchini: Excess salt can draw out too much moisture, leaving your casserole soggy. Use only 1/2 teaspoon of salt and ensure you squeeze out any excess liquid from the shredded zucchini.
  • Skipping the onion and garlic: These ingredients add essential flavor to your casserole. Don’t skip them; finely chop or shred them for even distribution throughout the dish.
  • Not preheating the oven: Baking in a preheated oven ensures even cooking and proper texture. Make sure to preheat your oven to 375°F (190°C) before placing your casserole inside.
  • Ignoring the cheese mix: Using only one type of cheese may result in a bland dish. Combine parmesan, mozzarella, and cheddar for a rich, cheesy flavor that elevates the casserole.
  • Using stale breadcrumbs: Fresh panko crumbs provide a better crunch and texture. Ensure your panko crumbs are fresh for optimal results.
