What Is Zucchini Slice?

If you're like me and grew up in Australia, you could easily be mistaken for thinking that everyone in the entire world knows what zucchini slice is and eats it on a regular basis... but apparently this just isn't the case!

Zucchini slice is a classic Australian recipe and a much loved family favourite. And while it is less known worldwide, it's a delicious and no-fuss savoury bake.

Also known as impossible pie (because it's absolutely IMPOSSIBLE to mess up!!!), zucchini egg bake or crustless zucchini quiche, this simple slice is made using eggs, cheese, bacon, self-raising flour, oil and onion.

Once baked, zucchini slice has a beautiful golden crisp top and a moist egg based filling. It's an incredibly versatile dish that can be eaten for breakfast, lunch or dinner - and is just as delicious when served warm or cold.

Equipment Required

Absolutely no fancy equipment is required when making zucchini slice!

You'll also need a 18cm x 28cm (7 x 11 inch) rectangular baking tray and an oven.

What You Need

My quick and easy zucchini slice recipe is made using pantry and fridge staples - making it a budget-friendly option. 

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method

• Eggs - use large eggs (around 55g-60g each).
• Self-raising flour - also known as self-rising flour. You can buy this from any major supermarket or make your own self-raising flour using plain flour and baking powder.
• Oil - I recommend using vegetable oil in this recipe as it has a mild flavour. You can use canola oil instead, however, this will change the taste of the dish. Olive oil is not recommended for zucchini slice as it has too strong a flavour.
• Cheese - any brand of tasty or cheddar cheese works beautifully in zucchini slice. You can also add some parmesan cheese to the mixture for extra flavour if you like.
• Zucchini - also known as courgette. This recipe is a great way to use up zucchinis when they're in season. Zucchini is the common term used in American English speaking countries, while courgette is the more common term among French and British English speaking people. Different name - same thing!
• Onion - use a medium-sized brown onion.
• Bacon - you can use any kind of bacon or ham for this recipe. Streaky bacon, middle bacon rashers, shortcut bacon or deli ham all work well. This is also a great way to use up any leftover Christmas ham (simply chop into small chunks). 
• Salt & pepper - to season.

Step By Step Instructions

Serving Suggestions

Thermomix Zucchini Slice is absolutely delicious served on it's own... or you can take it up a notch by serving it with a tasty side:
