Common Mistakes to Avoid

When making Zucchini Pizza Casserole, avoiding common mistakes will ensure a delicious outcome. Here are some pitfalls to steer clear of:

  • Using wet zucchini: Excess moisture from the zucchini can make your casserole soggy. Always grate and drain the zucchini well before mixing.
  • Skipping the seasoning: Failing to season adequately can lead to bland flavors. Use Italian seasoning and other spices generously for a robust taste.
  • Overcooking the turkey: Cooking ground turkey too long can dry it out. Cook just until no longer pink and mix in the marinara sauce promptly.
  • Neglecting the baking time: Baking for too long can cause the cheese to burn. Keep an eye on it during the final bake for a perfectly melted topping.
  • Not greasing the pan: Skipping this step may result in sticking. Always grease your baking pan to ensure easy removal of the casserole.

Refrigerator Storage

  • Store leftovers in an airtight container for up to 3 days.
  • Allow the casserole to cool completely before refrigerating.
