Ingredients

  • 4 medium zucchinis, grated
  • 1 large onion, finely chopped
  • 1 cup grated cheddar cheese
  • 1/2 cup grated parmesan cheese
  • 1 cup self-raising flour
  • 5 large eggs
  • 1/3 cup milk
  • 2 cloves garlic, minced
  • 2 tablespoons fresh parsley, chopped
  • 1 teaspoon dried oregano
  • Salt and pepper, to taste
  • Olive oil spray or butter, for greasing

Equipment

  • Large mixing bowl
  • Grater or food processor (for shredding zucchini and cheese)
  • Chopping board and knife
  • Large baking dish or slice tin (approx. 9×13 inches)
  • Whisk or fork
  • Measuring cups and spoons
  • Oven
  • Spatula

Instructions

  1. Preheat your oven to 180°C (350°F) and grease your baking dish with olive oil spray or butter.
  2. Prepare the zucchini: Grate the zucchinis using a grater or food processor. Place the grated zucchini in a clean kitchen towel and squeeze out as much moisture as possible to avoid a soggy slice.
  3. Sauté the onion and garlic: In a small pan over medium heat, lightly sauté the chopped onion and minced garlic until soft and fragrant (about 5 minutes). Set aside to cool slightly.
  4. Mix dry ingredients: In a large bowl, combine the self-raising flour, grated cheddar, parmesan cheese, dried oregano, salt, and pepper. Mix well.
  5. Combine wet ingredients: In a separate bowl, whisk the eggs and milk until fully blended.
  6. Assemble the mixture: Add the grated zucchini, sautéed onion and garlic, fresh parsley, and wet ingredients into the dry ingredients bowl. Mix everything thoroughly until you have a uniform batter.
  7. Pour the batter into the prepared baking dish and spread evenly with a spatula.
  8. Bake for 35-40 minutes or until the slice is golden on top and a skewer inserted into the center comes out clean.
  9. Allow to cool for 10 minutes before slicing. This helps the slice set and makes it easier to cut.

Tips & Variations

“For a gluten-free version, substitute the self-raising flour with a gluten-free baking mix or almond flour.”

You can easily adapt this zucchini slice to suit your taste or dietary needs. Try adding some chopped sun-dried tomatoes or olives for a Mediterranean twist.

For a spicy kick, sprinkle in some chili flakes with the herbs. If you like it extra cheesy, feel free to add mozzarella or feta cheese instead of cheddar.

Make sure to squeeze out as much moisture from the zucchini as possible. This step is crucial to prevent the slice from becoming too wet and falling apart.

Using fresh herbs instead of dried can also elevate the flavor significantly.
