What is a zucchini slice?
I first heard about zucchini slice when I moved to Australia. Over here it’s eaten as a snack and is a popular option in children’s lunch boxes and at birthday parties. It’s also part of the weekly dinner rotation for many families, served with a salad to make a complete meal. The reason it’s so popular is because it’s super easy to make and is a healthy & delicious meal option loved by adults as well as kids. It’s also known as the Zucchini Egg Bake and it’s similar to a quiche but without the fiddly crust. The traditional Aussie recipe calls for combining zucchini, bacon, eggs, cheese, and spices and then pouring into a baking dish to bake. I have made a vegetarian version of this Australian classic as I don’t eat bacon.
How to make a vegetarian zucchini slice?
- Prepare the vegetables: Start off with prepping your vegetables. Shred the zucchini and carrots and dice up the onions. You can also add other vegetables such as olives, corn, capsicum, baby spinach, broccoli or boiled and shredded chicken if you want to add protein to this slice.
- Whisk up the eggs: Crack eggs in a bowl, and whisk for about 30 seconds. The eggs form the base for the zucchini slice.
- Add the cheese and spices: I have kept the spices simple in this slice recipe – just herbs, red chili flakes and chopped onion flakes. You can keep it simple with just salt and black pepper, or spice things up by adding the spices of your choice.
- Mix it all up: Add the vegetables, flour, cheese, oil and spices to the eggs and mix it altogether. The flour is used to add structure to the zucchini. If you want a gluten free version, you can use a gluten free flour.
- Bake: Pour the zucchini slice batter into a prepared rectangle baking pan. I have used a lamington tin (16 cm x 26 cm). You can use a half sheet baking tray, a slice pan, or a deep cookie tray. Once the zucchini slice is ready, it can be eaten hot or cold.
How to store this vegetarian slice?
The zucchini slice can be kept for up to 4 days in the fridge in an airtight container in the fridge. It can also be frozen making it ideal for meal prep. Wrap the slice pieces individually in plastic wrap, then place in an airtight container or in sealed freezer bags. Keep in the freezer for upto 3 months. To defrost, let the slices thaw at room temperature, or place in the fridge to thaw overnight. If you are adding to kids lunch boxes, frozen zucchini slices can be added to lunchboxes in the morning, and they will thaw by lunch time.
Zucchini slice – the variations:
This zucchini slice is super adaptable, and you can change up the ingredients to suit your personal preferences, or what is available to you. Here are some options to change up the recipe.
- Add other vegetables such as baby spinach, peas, corn, capsicum, olives, sauteed mushrooms, or tomatoes. If using tomatoes, use small tomato slices or halved cherry tomatoes. Add them on top of the batter so that they caramelize in the oven.
- Add fresh herbs such as chopped chives, dill, parsley, or coriander.
- Use a different type of cheese such as mozzarella, pepper jack, Colby. It’s also possible to use a fresh cheese such as feta cheese, ricotta, or paneer (Indian cottage cheese).
- Leftover vegetables in the fridge, from roasting or from an Asian stir-fry can be added to the batter to jazz up the flavor.
- It’s also possible to add meat to this zucchini slice, such as ground mince or boiled and shredded chicken. If adding meat, cook it separately and then add to the batter.
- You can also saute the vegetables in oil and garlic, then add them to the batter. This adds another flavor dimension and can be preferred by people who are not a fan of raw vegetables.

Pour the batter in the greased and lined tray. Bake in the pre-heated oven for about 35 – 45 minutes till the mixture is set, and the top is light golden brown.

Remove the slice from the oven, and let it cool for a few minutes. It will firm up and be easier to cut after it has cooled down a little.
