Thermomix Zucchini Slice is an all-time family favourite!

Made from budget-friendly ingredients, this healthy savoury slice takes just 10 minutes to prepare using your Thermomix!

Forget about grating or mixing, the Thermomix will do it ALL for you... and with only one bowl to wash up!

Zucchini Slice is certainly a favourite recipe here in Australia.

It's a savoury slice made from grated zucchini, eggs, cheese, bacon (or ham) and flour, which is then baked until golden on the top and moist in the centre (a bit like a cross between a quiche and a savoury muffin).

While zucchini slice is a very easy recipe to make the good old fashioned way with a bowl and a mixing spoon, it is SO much quicker and easier using a Thermomix machine!

The Thermomix will grate your vegetables and cheese, chop your bacon and mix together the entire slice batter... all in one bowl (and in less than 10 minutes!).

Why You're Going To Love This Recipe

Everyone loves this easy Thermomix Zucchini Slice... here's why it's so popular:

Budget-friendly - zucchini slice is made using pantry and fridge staples. Best made when zucchinis are in season (and extremely cheap!), this slice costs very little to make but goes such a long way.
Serve warm or cold - while I prefer to eat zucchini slice warm with a spoonful of chutney or relish and a side salad, it is just as delicious served cold (which is a great option for lunch boxes).
Fussy kid-approved - I have never known a kid to turn their nose up at zucchini slice (and I had a SUPER fussy toddler!!!). The grated cheese and bacon gives this mild flavoured slice a kid-friendly flavour boost.
Freezer-friendly - I like to make a double batch and freeze the leftovers. Thermomix zucchini slice can be stored in the freezer for up to 3 months (either as as entire slice or cut into individual pieces).
One bowl - the Thermomix really is a dream machine when it comes to making zucchini slice! The entire batter is prepared in the Thermomix - meaning that you only have one bowl to wash afterwards!

Equipment Required

The Thermomix makes preparing zucchini slice an absolute breeze!

Not only will it grate your onion, zucchini and cheese, it will also chop your bacon AND mix the entire batter together - how amazing is that!

This recipe is suitable for use in any of the Thermomix models (TM31, TM5 and TM6) or any other Thermal cooker.

What You Need

Thermomix Zucchini Slice is made using basic ingredients that you may already have at home!

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

Cheese - the grated cheese gives this zucchini slice a BIG flavour boost! I recommmend using a cheddar or tasty cheese.
Zucchini - also known as courgettes. Unlike many recipes that use grated zucchini, there's NO need to strain the zucchini as it gives the savoury slice a deliciously moist texture in the middle.
Onion - use a medium brown onion.
Bacon - alternatively you can substitute the bacon for ham. For a vegetarian option, you can omit the bacon entirely.
Eggs - use large eggs at room temperature (approximately 60g per egg).
Self-raising flour - you can use store-bought self raising flour or make your own self-raising flour from scratch using plain (all purpose) flour and baking powder.
Vegetable oil - this is a mild flavoured oil that gives the slice it's beautiful and moist texture. Unlike olive oil which is not suitable for this recipe due to it's strong over-powering flavour, vegetable oil perfectly complements this savoury slice. Alternatively, you can use canola oil in place of the vegetable oil.
Salt & pepper - to taste.

FAQs

Can I make zucchini slice into a vegetarian slice?

Absolutely! Simply omit the bacon in the recipe.

Can I make zucchini slice without a Thermomix?

Yes, of course. You can find my conventional Zucchini Slice recipe here.

Is zucchini slice mushy?

Not if it is cooked through thoroughly (see my tips below for testing if the slice is cooked). While the eggs give the zucchini slice an egg/quiche-like texture on the inside, the self-raising flour prevents it from becoming gluggy or mushy.

Expert Tips

Test to see if the slice is cooked through by inserting a skewer into the centre - if the skewer comes out clean, it's ready. If it's 'eggy' or wet, it needs longer to bake.
The top of the slice should be golden and firm while the inside will remain moist.
If you find that your slice is over-browning, simply add a sheet of foil loosely over the top and continue cooking.
Make this vegetarian by omitting the bacon.
Store in an airtight container in the fridge for up to 5 days.
Freeze in an airtight container for up to 3 months, either as a whole, or wrapped in individual pieces. Allow to defrost before consuming cold or warmed up.
