Thermomix Zucchini slice is one of my favourite "go to" recipes. It's packed with healthy zucchini plus the bacon & cheese make it irresistible.
Whenever I'm looking for a quick, healthy meal to serve I inevitably fall back on this dish.
The recipe ticks all my boxes, it's delicious and quick to make and everyone always LOVES it! The best part is it includes hidden vegetables, plus the leftovers make a great lunchbox idea. There is always a fight over who gets to take the leftovers to lunch or school.
Zucchini Slice Tips
- This recipe freezes well so if you're one of these super organised mums you could make and freeze the recipe ahead of time. Cut the slice into serving sizes before freezing. The individual portions can be used for school lunches or single-serve dinners on busy nights.
Unfortunately, I have never been that organised, so my kids fights it out for the measly leftovers.
- Note I've made the Thermomix zucchini slice in a slice tray and a mini loaf tin. If you do use a loaf tin make sure you line it with baking paper so it doesn't stick. You could also make these in large muffin trays with cupcake wrappers. The cooking times will alter depending on what tray you use.
Serving Suggestion
- The zucchini slice makes a healthy main meal when served with a large, fresh salad.
- Serve with a pouch of "heat and serve" pre-cooked quinoa and brown rice.
- Kids may enjoy some oven-fried chips with their zucchini slice.
More School Lunchbox Idea
Keeping lunchboxes interesting can be hard work! Especially when both parents are working. The alternative of buying commercially prepared treats can be expensive, and it's difficult to know exactly what you are feeding your child. If you can find time to make a big batch of lunchbox food during the weekend or holidays it can really reduce stress during the working week.
These Homemade LCM Bars may not exactly be healthy food but they are a delicious addition to any lunchbox and far cheaper than their commercial counterparts.
Zucchini Slice FAQ
These are suitable for freezing but cut the slice before freezing and add to individual sandwich bags for easy access.
Yes, you can successfully swap to GF Flour if required. Adding an extra egg will help to make the slice more stable.
You can alter the vegetables in the slice. Make sure you squeeze out any excess water and keep the volume of vegetables the same.
All ovens are slightly different in heat distribution and in sealing in the heat. If you feel the slice isn't cooked properly continue to let it back.
You don't need to use the same size baking tray as I have in the recipe, although a deeper tray will take longer to cook. A shallower tray will cook more quickly. I like using these mini loaf trays for individual serves as you can see in the images. The make a great lunch box idea.

Honestly the BEST zucchini slice I’ve ever made! Normally they are wet and gluggy but this was honestly perfect and we added cherry tomatoes on top so it gave that yummy pop of juice too!
Annette Willet says
I made muffins as suggested and they were so delicious thanks Julie x
Julie Carlyle says
I'm so pleased you enjoyed the recipe 🙂

Mel says
Why do you only blitz 1/4 of the onions/zucchini? Do you do these steps 4 times?
Julie Carlyle says
Hi Mel,
Perhaps I haven’t written the instruction clearly enough. I mean for you to cut the onion into quarters before you add it to the TM bowl. The same is true for the zucchini, cut it into quarters, place in the bowl and then blitz.
I hope that helps
Happy cooking

Flip says
Didn’t change one thing- all my fussy eaters ate their whole serve.
Told them it was quiche at the start then once they had finished it I told them it was zucchini
Emma Ryan says
This was delicious. I didn’t have 550 grams of zucchini so I had zuchinni brocolli, carrot and corn make up the 550g. The key really is getting rid of the moisture. I added some vegetable stock and the kids couldn’t get enough
Julie Carlyle says
Hi Emma
I absolutely agree, the key is getting rid of any excess moisture. Love the stock paste idea too! Yum.
Thanks for coming back and commenting.

Stupid question - what's a TM bowl?
Julie Carlyle says
Hi Frieda
This isn’t a silly question TM bowl means Thermomix bowl.

Could you use almond flour to make it Keto?
Julie Carlyle says
Hi Jennifer
I haven’t
Used almond flour in this recipe so I really don’t know what effect it would have. Please let me know if you make the swap successfully.

tracey says
Hi,
I was wondering why the inside of the zucchini slice is still very moist and soggy despite putting in the oven for > 45min?
Thanks.
Brett Carlyle says
Hi Tracey, as the zucchini is moist, you must wring it out after chopping to remove as much of the liquid as possible to prevent the slice being moist and soggy. If you find it moist, try leaving it in the oven at a lower temp (ie, 100*) for 10-15 minutes to remove the moisture
Lyndall says
My grandson keeps asking me to make this, he loves it so much. Oh if only he know the main ingredient :- )
Think is going to be my 'go to' recipe for his lunch when he starts prep later this mth. I'm hoping to get organised and have a freezer packed ready to go.
Julie Carlyle says
Hi Lyndall,
That is fabulous to hear!!! I’m so pleased your grandson enjoys this. It’s a great dish, and so portable 👍🏻👍🏻👍🏻

Susan says
What a great recipe. Thank you.
Made muffin size ones (24), omitted bacon & substituted with carrot. Added a little salt, black pepper & basil.
Cooked for 20mins..
Fantastic. Ready to be delivered to a customer who wanted courgette muffins.
Hope she will be pleased with them.
Had to make another batch for hubby as he said they were sooo good. 👏👏
Susan says
Could one make this gluten free by using gluten free flour?
How many slices can I get ?
Julie Carlyle says
Yes, I have made this with Gluten Free flour and it has worked perfectly.

Agatha says
Can you substitute the bacon for a non-meat alternative?
Julie Carlyle says
Hi Agatha,
Yes you can substitute the bacon for 3/4 cup of sun dried tomatoes. It’s still absolutely delicious.

ahhh sorry meant to be 5 stars
meg says
Just made this and its delicious
I added the salt and pepper from the comments (didn't cook bacon first, aint nobody got time for that) and added a small tin of corn kernels.
my mums makes an old school version of this and I love it but could never be bother to grate up a tonne of zucchinis, so im happy ive found a cheats way
Lien L says
Thanks Julie for sharing this recipe! Best zucchini slice ever! I tripled the recipe to make a big batch in two large baking trays, added salt and pepper to taste, cooked bacon first, squeezed zucchini & onion, and added a bit of carrots as well! It was super morish !
Eva says
Without a doubt - the very best zucchini slice I've ever made/eaten ... thanks for sharing!
I used a nylon straining bag (nut milk bag) to squeeze out the 'onion/zucchini mix' liquids -peeerfect.
Precooked the bacon in the Thermomix - 3 mins/100/reverse/speed 1 (2 min's with MC on -1 min with MC off).
Strained fat/liquid from cooked bacon.
And ... I used half tasty cheese/half parmesan.
Yum ... and thanks again!
Julie Carlyle says
Hi Eva! I'm so pleased you enjoyed the recipe. by pre-cooking the bacon you will have removed some of the fat from the recipe. This will make it a leaner, healthier dish. Personally, I'm naughty and allow the bacon to cook in the slice adding fat and flavour. The dish is fabulous regardless which method is used but I'm so pleased you pointed out that way of cooking as I'm sure it will appeal to readers who are conscious of calories 🙂
Thanks again and happy cooking

Wow, this was a fantastic find - delicious! Many thanks
Julie Carlyle says
Hi Steve, I’m so pleased you enjoyed the recipe, thanks so much for coming back and leaving a message and a rating. This is one of my favourite quick recipes ?
Karen says
Wow best zucchini slice I have ever made, I added a little salt,pepper and chili flakes!
Absolutely delicious, thank you sharing your recipe ?
Julie Carlyle says
I'm so pleased to hear that Karen! Thank you for sharing 🙂
Katia says
Thanks for the recipe! Very good, we will make again. For beginner cooks, though, you forgot to mention that bacon needs to be cooked already before adding to mixture, and to add salt/pepper to taste (mine was a bit bland).
Julie Carlyle says
Hi Katie, thank you for your message. I love hearing from people that have made my recipes. I will add salt and pepper to taste to the recipe. I actually don’t add salt as I find the bacon is salty enough. The bacon point is interesting, I’ve never cooked the bacon first. I’ve been making this slice since it first “came out” in the early 80’s and even the original recipe included raw bacon. I’m wondering if cooking the bacon first took some of the salt and oils out of the slice and made it on the bland side. Also the oil from the bacon is needed for the texture and flavour ofthe slice.I would love you to try the recipe again with raw bacon and let me know what you think. Once again, thank you so much for your message. I will amend the recipe to make it easier to follow. Julie xx
Megan M says
The supermarket had run out of zucchini so I supplemented with kale- delicious.
Would try it with other veggie options in future!
Julie Carlyle says
What a fabulous idea!!
