This is a savoury zucchini cheese muffin in slab form which is a handy big-batch zucchini slice recipe to serve lots of people without fussing with muffin tins (I know you hate cleaning them too!). Economical. Hidden veg. 5 day shelf life. CHEESE. I challenge you to think of a reason not to make these immediately! 🙂

Zucchini cheese muffin slab
Adapted from my Zucchini Cheese Loaf, this is a recipe that came into existence when I was shamelessly baking for the staff at the animal hospital when Dozer was in for surgery. Who me, bribing the doctors and nurses with baked goods to ensure Dozer got extra care and attention?? Never! 😇
Truthfully though, after 3 batches of muffins I lost the will to clean yet another muffin tin (paper liners just seem out of place with savoury muffins?) and flipped over to what I christened a zucchini slab-muffin. So much easier to make one big slab then cut it into pieces than using muffin tin after muffin tin!!
Though the initial versions were just fine, over the past few weeks I’ve been tweaking the recipe to make it even better (thank you team RTM for your brutally honest feedback!) to make the crumb softer and fluffier, and extend the shelf life to 5 whole days. I’m so happy with the end result, and I hope you love it too!

Ingredients in Cheesy Zucchini Muffin Slab
Zucchini is the key ingredient in this muffin slab. It’s not just about sneaking in extra veggies or the lovely little green bits inside. It’s also keeps this muffin-slab fresh for up to 5 days, thanks to the moisture in the zucchini!
Zucchini

I use 3 zucchinis in this recipe. Two are grated and stirred into the batter, after sweating out excess water using a little salt. Zucchinis are over 90% water! The third is used to decorate the top.
I haven’t tried other vegetables in this recipe because my gut tells me the crumb will be a little drier than ideal. Even after squeezing out the excess water in the zucchini, there is still plenty of water in it which gets leeched out into the batter as it bakes. In fact, you’ll notice that the batter is a bit thicker than typical muffin batters – that’s to allow for residual zucchini moisture!

Dry ingredients

Plain flour (all-purpose flour) – Not self raising flour which already has baking powder built in. Generally speaking, cakes and muffins don’t rise as nicely and the crumb is not as soft. Better to add your own rising agent, like baking powder.
Baking powder and baking soda (bi-carb) – This recipe specifically uses both because it makes the softest crumb with an even rise (rather than a big dome). I know it’s irritating to have to use both, but it really does give the best result. I tried all sorts of combinations! However, if you’ve only got baking powder, you can substitute the baking soda with an extra 1 1/2 teaspoons of baking powder, though the crumb will be a touch less tender (it will rise almost as well though).

Plain white vinegar – Acidity that gives the baking soda a kick start on the rising! You can’t taste it at all, it’s just to activate the baking soda. Either vinegar or something else with acidity in it (like yogurt or sour cream) is fairly standard in most of my baking recipes that use baking soda. I use regular white vinegar but any clear(ish) vinegar will work just as well. Don’t use balsamic vinegar!!! 🙂
Cheese – Use your favourite melting cheese like cheddar, tasty, colby (this is my everyday cheese), Monterey jack (this was, but difficult to find in Australia these days), gruyere (if your wallet stretches to this) etc. PS Pre-shredded is fine for this recipe!
Mozzarella is not recommended because it does not have much flavour. If I were to use mozzarella, I’d probably use 150g / 5 oz mozzarella plus 75g / 2 1/2 oz parmesan.
Milk – Full fat cow milk is best, though low fat works too.
Large eggs, at room temperature – 55-60g/2oz eggs from a carton labelled “large eggs”. Make sure they are at room temperature not fridge cold. More on eggs for baking here (including a quick way to de-chill them).
Oil and butter – Oil keeps cakes and muffins moist whereas butter adds flavour. Muffins that dry out the next day really bother me, so I was adamant that I wanted to use a bit. However, I missed the flavour of butter when just using oil. So I landed on a combination of both! Use any neutral flavoured oil.
Garlic – I love the hint of garlic flavour in this muffin-slab! Use fresh garlic cloves (not dried), crushed using a garlic crusher or finely grated using a microplane. If using a knife, finely mince it then use the side of the knife to smear it into a paste.
How to make Zucchini Cheese Muffin Slab
I know it’s tempting to skip the zucchini sweating. I tried. And regretted it. The batter just got too soggy and didn’t cook through!
If you really short on time, you can reduce it to 10 minutes sweating time but use a tea towel to wring out the excess water (you’ll get more out than using hands).

Sweat 20 minutes – Sprinkle the grated zucchini with salt and toss. Set aside for 20 minutes to draw water out.
Squeeze out excess water using your hands. Just grab handfuls and squeeze. There’s no need to remove every single last drop (to do that, I’d ask you to use a tea towel) because the batter is deliberately designed a little thicker than typical as we will rely on residual water in the zucchini to add moisture as it bakes. But please make a bit of effort during this squeezing step!
How much you need – We need 2 very tightly packed cups of squeezed out zucchini. A little more of less is fine, the recipe is pretty flexible. But if you have, say, 3 cups, that will weigh down the batter a little too much.

Decorative topping – Slice the third zucchini thinly however you’d like (I do lengthwise then halve, coins is also nice). Then toss with a little oil and pepper (not salt, it makes it sweat, we will salt later).
Whisk dry – For the batter, it’s delightfully straightforward as most muffins as. Whisk the dry ingredients in a large bowl (flour, baking powder, baking soda and salt).

Whisk wet – Then whisk all the wet ingredients in a separate bowl. Important to have all ingredients at room temperature else it won’t combine smoothly. For example, a jug of cold milk added into melted butter will make the butter solidify!
Combine – Then pour the wet ingredients into the dry ingredients. Mix until the flour is mostly incorporated, but not fully. Stop mixing when you can still see some bits of flour.

Add-ins – Then add the cheese and zucchini and mix them through. Stop mixing once the zucchini and cheese is dispersed. Over-mixing will make the crumb less soft than it should be!
Spread into a 23 x 33 cm / 9 x 13″ paper lined pan (I grease with butter).

Top with the zucchini slices.
Bake for 40 minutes or until a skewer inserted into the centre comes out clean. Let it cool for a bit, then it’s ready to eat!

Serving and storage matters
This is one of those foods that has a place from morning to night, whether it’s a breakfast on the run, a filler for your lunch box, after school snack or taking into the office to share with co-workers. I also particularly like that it’s “grab and go” without the need to fuss with plates for serving. Just a napkin, if you’re feeling civilised!
It will stay fresh for up to 5 days in an airtight container in the fridge, though if it’s not too warm where you are then you can even just leave it in the pantry. The crumb stays moist thanks to the moisture in the zucchini as well as the oil in the recipe. And even at the tail end of its shelf life, a quick little toast in the oven is all it will take to rejuvenate.
Love to know what you think if you try this! In particular, I’d love to know what people use it for. Feeding hungry teenagers? Morning tea in the office? Book club?? Tell me, I want to know! – Nagi x

Zucchini cheese muffin slab
Ingredients
- 2 zucchinis (300g / 10 oz, ~17cm/7″ long) (Note 1)
- 3/4 tsp cooking salt / kosher salt
- 2 cups (tightly packed) shredded cheese at room temperature , like cheddar, tasty, colby, I use pre-shredded (Note 2)
Decorative topping:
- 1 medium zucchini
- 1 tsp extra virgin olive oil
- Pinch black pepper
- 2 pinches sea salt flakes (optional, for sprinkling at end)
Dry ingredients:
- 2 3/4 cups flour , plain/all purpose
- 3 1/2 tsp baking powder
- 1/2 tsp baking soda / bi-carbonate of soda (Note 3)
- 1/2 tsp cooking salt / kosher salt
Wet ingredients:
- 2 garlic cloves , crushed using a garlic crusher or finely grated using a microplane
- 1 cup milk , preferably full fat, at room temp (I microwave 20 sec)
- 50g / 3 tbsp unsalted butter , melted, cooled
- 3 tbsp neutral oil (canola, vegetable, peanut)
- 2 large eggs (55g/2 oz each), at room temperature
- 1 tsp white vinegar (Note 4)
Instructions
Preparation:
- Sweat zucchini – Grate 2 of the zucchinis using a box grater. Toss with the salt then set aside for 20 minutes. Grab handfuls and squeeze out excess liquid (no need to be super forceful here but make a bit of effort!). You should have 2 very tightly packed cups. Set aside.
- Decorative zucchini – Finely slice the 3rd zucchini however you want, to decorate the surface. I cut the zucchini in half then into long strips. Thin coins is also nice. Toss with the oil and pepper.
- Preheat the oven to 200°C/400°F (180°C fan-forced). Lightly grease a 23 x 33cm / 9 x 13" metal pan with butter. Line with paper with overhang (so you can lift it out later).
Bake:
- Batter – Whisk the Dry ingredients in a large bowl using a handheld whisk. Make a well in the centre. Whisk the Wet ingredients in a separate bowl until combined. Pour the Wet into the Dry ingredients. Mix using a wooden spoon until the flour is mostly incorporated but there's still flour visible.
- Add-ins – Add zucchini and cheese then mix through. Some flour lumps is fine. Minimise mixing else the crumb will be tough. The batter will be thick – the zucchini will sweat more in the oven.
- Bake – Scrape into the prepared pan and smooth the surface. Top with the zucchini slices. Bake for 40 minutes or until a skewer inserted in the middle comes out clean.
- Cool – Sprinkle with sea salt flakes. Cool in the pan for 10 minutes. Use the excess paper to slide the slab onto a cooling rack then remove the paper. Cool for at least another 10 minutes.
- Cut into pieces (3 x 5 pieces, or 4 x 5). Nobody ever says no to a smear of butter either, especially if served warm!
Recipe Notes:
Life of Dozer
His first visit back to Bayview dog beach after his surgery. Look at that smile. ❤️

I know that photo is wonderfully upbeat. And it truly does capture a moment that made me so happy! But the reality is, he didn’t swim. He just broke out into a trot for a brief moment and I happened to snap a photo. 😂
The truth is, he is still very much on a path to recovery. I’m learning to be patient and to lower my expectations for the pace and how much fitness/strength etc he will manage to regain. He is still a shadow of what he was 3 months ago before his laryngeal paralysis came on so swiftly. But I’ve taken him in to see a canine physiotherapist who has given me exercises to help strengthen his muscles (it’s amazing how much muscle mass he has lost in 3 months) which will help let him enjoy being out and about more.
He gets out and up more than did pre surgery, but still spends the vast majority of each day resting.
In good news though, high-value food does pique his interest enough to get up and get in the way once again, like he used to! Here he is at a photoshoot yesterday – that’s Rob Palmer (professional photographer) on the left and our Chef JB on the right.

And here are a few more snaps of Dozer over the Easter break. Babysitting the slow roasted lamb:

Ah yes, and his worried face at the sight of the Easter hats…. 😂

And I’m not quite sure if this is his tolerating face (from the bear hug) or relaxing face (from the belly scratches)!

Thank you once again for all the wonderful messages of support, cheering on Dozer’s recovery! I hope to be able to continue to bring positive news, and I promise to remain completely dedicated to his rehab! – Nagi x
I’ve been thinking of you and Dozer so much – it’s been great to get the update and photos tonight 💜
Oh Nagi I’m so glad to see him up and about and all the lovely photos . He will get stronger every day x Give him a kiss from me x
It looks delicious! And at last – having watched your video – I know that one doesn’t rinse off the salt before squeezing the salted vegetable.
My very best wishes for a happy Dozer. He couldn’t be more loved.
Was there a recipe. I only saw beautiful Dozer
🥰🥰
Yes, I’m also one who scrolled down to the Dozer update first. Glad to see he’s getting his quality of life back, albeit slowly – but remember the old adage “slow and steady wins the race”. Dozer, you are a star, and loved more than you can ever understand, both at home and internationally by your huge fan club. Just keep improving by the day, please. So glad you enjoyed your time at the beach. Retrievers and water go hand-in-hand!
Had to scroll down without reading the recipe. Dozer’s update much more important
I did the same…….but I always check the “Dozer report” before looking at the recipes!
Yep I’m one of those who read about Dozer before the recipe!
So glad that he is still improving and every day is precious. I’ll never understand how people can hurt animals when their love is unconditional and they are always there for you even if it is in your heart and memories.
So glad to see the gorgeous Dozer making progress, puppy steps but getting there.
That picture of you hugging him under the table brought tears, it was so beautiful. I am the same with my furbaby here, he means the world to me and comes first always. Hugs and tons of prayers for both of you as you are a super marvelous momma.
I bet I’m not the only one who scrolled down for the Dozer update before reading the recipe! Thanks for both, Nagi 😊 xx
LOl……..I do the same, they are just part of my family here.
God bless you Nagi. I love to read about you and Dozer. You are so blessed to have each other. Thanks for all your delicious recipes
So nice to have you back in my inbox and even nicer to hear of Dozer’s recovery!!!!!
(Can’t wait to try this recipe also!)
Go Dozer!
I always look forward to your recipes and have so enjoyed your dinners recipe book, but l love the pictures of Dozer. So happy to see him.
Oreo and Gabbi my 2 cats are sending Dozer lots of love and support.
Dozer photos make me smile. Lucky dog to have such a caring clever mum.. Nothing like unconditional love from a furbaby
It is so good to see him up and about. Hang in there girl
Hi Nagi! The recipe pic looks fabulous and will definitely try but I admit to scrolling madly through for the Dozer update. He is so very very adorable and it’s clear you are full of love for each other. Well done!! 🐾
Oh my!
You have made my day – night! – Nagi! Thank you!
What a beautiful snap of Dozer in the water, and such an encouraging report on his recovery. The other snaps are a delight too!
Slow and steady is the best way to healing . . . with your dedication and love for him, he’ll get there. And don’t forget about all of the positive energy being sent your way from all of Dozer’s (and your!) loving fans!
My heart feels lightened now, and I will continue to keep both of you in my prayers.
It is lovely to see another recipe offering from you – which looks and sounds delicious! – and I hope in some way, it can help you start to heal too by getting ‘back in the kitchen’.
I’m off now to see what I need at the grocers for the Cheesy Zucchini Muffin Slab!
Again, I am so excited for you and Dozer!
Sending Love and Hugs, Nagi.
“Cheers” from the Canadian Prairies.
Since Dozer’s illness I confess that I go straight to Dozer first and then the recipe. Thanks for taking the time to let us all know how he is doing. We all care so much. 💕
So good to see Dozer up and about and looking stronger. I know you love him with all your heart and soul. Pretty cool.
I haven’t tried the recipe yet but zucchini is one of my favorites. And, cheese ANYTHING is definitely at the top of my list… Really don’t see how this could go wrong! Thanks!
