    This zucchini slice recipe has been a go-to in Aussie kitchens for decades – and for good reason! It’s quick to prepare, packed with veg (perfect for sneaking in some veggies), and can be served warm or cold. It’s also a great way to use up zucchinis that are lingering in the fridge!

    I’ve kept this version nice and simple, with just one bowl needed and no fiddly steps. It’s ideal for busy weekdays, lunchbox packing, or even cutting into bite-sized squares for picnics and parties. And with both conventional and Thermomix methods, you’re sorted no matter how you cook.

    Slice Ingredients

    Here’s what you’ll need for this simple slice. Most of it will already be in your fridge or pantry:

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

    The ingredients for zucchini slice.
    • Zucchini – Grate it finely and give it a gentle squeeze to remove excess liquid. This helps avoid a soggy base.
    • Cheese – Tasty, cheddar or even mozzarella all work well here. Grate it fresh for best results.
    • Bacon – Adds flavour and saltiness, but you can swap for ham or leave it out entirely for a vegetarian version.

    Variations

    Make this zucchini slice your own with these simple swaps and add-ins:

    • Cheesy twist – Try adding crumbled feta or swapping tasty cheese for parmesan.
    • Vegetarian – Skip the bacon or replace with chopped sundried tomatoes or olives.
    • Gluten-free – Use a good-quality GF self-raising flour blend.
    • Extra veg – Add grated carrot, corn kernels, baby spinach or even sweet potato.

    How To Make Zucchini Slice

    This is such an easy recipe to pull together – just one bowl (or your Thermie) and you’re away!

    Top Tip

    Grate your zucchini first and gently squeeze it to remove excess moisture – this helps keep the base firm, not soggy.

    Recipe Tips

    • Check for doneness – The slice should be golden and firm on top. A skewer inserted into the centre should come out clean.
    • Avoid sogginess – Gently squeeze excess liquid from grated zucchini before mixing.
    • Use baking paper – This makes it easy to lift the slice out once cooled.
    • Add foil if over-browning – Loosely cover the top with foil during the last 10 minutes if needed.
    • Serve hot or cold – Delicious straight from the oven or chilled in lunchboxes.
    • Storage – Store in an airtight container in the fridge for up to 5 days.
    • Freezing – Freeze cooled slice in individual portions for up to 3 months.
    • Reheat – Microwave 1–2 minutes or oven bake at 160°C until warmed through.

    Zucchini Slice FAQs

    How do I stop zucchini slice from going soggy?

    Make sure you squeeze out any extra moisture from the grated zucchini before mixing it into the batter. This keeps the texture firm and sliceable.

    Is this zucchini slice gluten-free?

    Not as written, but you can make it gluten-free by swapping the self-raising flour with a gluten-free blend that contains a raising agent.

    Can I make it vegetarian?

    Yes! Just leave out the bacon or swap for a handful of chopped veggies like capsicum, corn, or mushroom.

          Wow, this Zucchini Slice is so easy to make & so yummy! I omitted the bacon & the salt, due to my husbands health requirements, & used wholemeal self-raising flour.The whole Family really loved the slice, including our dog Murphy! The slice is equally tasty, either hot or cold. I thoroughly recommend this

      Do you not cook the bacon first? Recipe doesn't say, but I thought you have to be wary with pork and cooking times?
      This is the best zucchini slice recipe I've found. I added carrot and cherry tomatoes. My fussy 2 year old, who has refused zucchini slice for months, wolfed it down.

        Hi Odette, the bacon is chopped very small so it will cook in the oven (otherwise you can use ham if you prefer). Oooh delicious! I love smuggling in a few extra veggies too! xx
