Zucchini Slice

 This delicious Zucchini Slice is a firm family favourite. It’s a quick and easy no-fuss weeknight dinner or protein packed lunch. It’s fantastic warm or cold and makes a delicious non sandwich lunchbox idea. This slice is made from simple ingredients including zucchini, bacon, eggs, ricotta and cheddar cheese.

I love Zucchini Slice. It’s so simple to whip up for a quick weeknight meal served with a salad. And because this slice is fantastic warm or cold, you can easily prepare in advance for a super simple weeknight meal. And this Zucchini Slice makes a fantastic picnic addition or in the school lunchbox instead of a sandwich.

This delicious one bowl Zucchini Slice recipe is also really quick to prepare. Just chuck it all in a bowl and mix it together! How easy is that?

My recipe uses super simple ingredients that are readily available. And, I like to use ricotta instead of oil in this Zucchini Slice which adds such a light, soft and creamy texture. But while this family friendly Zucchini Slice recipe is light in texture, it’s still a very substantial meal and perfect for those busy nights or a simple but nourishing lunch.

Ingredients and Substitutions

This one bowl Zucchini Slice recipe uses readily available ingredients and I have noted some substitutions. You will find the quantity information in the recipe card.

  • Ricotta – this replaces the need for oil in this quick and simple Zucchini Slice recipe. I use a smooth ricotta that is very loose, more similar to a natural greek yogurt in consistency. If you do not have ricotta you could use sour cream, cottage cheesecream or oil. If using cream or oil I would reduce the amount to 1/2 a cup.
  • Eggs – packed with protein these are a base ingredient in this recipe. I used extra large free range eggs in this recipe. If using large eggs you may wish to add in another egg or two.
  • Zucchini – also known as a courgette, this is a nutrient dense vegetable that is packed with vitamins – it’s very high in Vitamin A – and minerals. You can peel the zucchini if you would like this less conspicuous in the mixture. There is no need to squeeze the excess liquid from the zucchini.
  • Bacon – I use a short cut bacon rather than rashers that are a bit fattier. You don’t need to pre-cook for this recipe but you can cook lightly with the onion and garlic if you like – I would recommend you do this if using rashers. I have also made this with a triple smoked bacon which was absolutely delicious.

  • Onion – adding more flavour to the recipe. You can cook off gently with the bacon and onion if you prefer. You also could omit but I would recommend leaving it in.
  • Garlic – adds a delicious flavour to this recipe. I crush mine but you could also chop finely if you do not have a garlic crusher. 
  • Tasty cheese – is a cheddar cheese. It’s aged so has a stronger flavour than cheddar, but cheddar would be a fine substitute. 
  • Parsley – elevates the flavour of the Zucchini Slice. Parsley is high in Vitamin K. You can omit if you don’t have any.
  • Salt and Pepper – seasons the recipe and bring out the flavours of the ingredients.
  • Self Raising Plain Flour – if you do not have self raising flour you can use plain flour and add in baking powder. To make self raising flour, mix two teaspoons of baking powder to each cup of plain flour. You could also use a wholemeal self raising flour.

How to make the Zucchini Slice

Preheat your oven to 180c and grease a large ovenproof dish. In a bowl add all the ingredients except for the flour and mix well. Add in the flour and stir again until just combined. Spoon into the prepared dish.

Bake the Zucchini Slice for around 30-35 minutes until cooked through, lightly golden on top and the sides of the slice are pulling away from the edges of the dish slightly. Leave to cool for 5 minutes before cutting into 8 pieces and serving.

Storing the Zucchini Slice

The quick, simple slice recipe can easily be made ahead of time and stored in the fridge for up to five days in an airtight container. You can also freeze the slice, but for best results you do need to use plastic wrap to protect the slice. You could also tightly wrap with baking paper if you wanted a plastic free option. To freeze, after cooking the slice cool completely. Then cut the Zucchini Slice into portions. Wrap each slice in plastic wrap or baking paper and place in an airtight container and store in the freezer for two to three months

Reheating the Zucchini Slice

Even though this Zucchini Slice comes together so quickly, it also reheats really well so you can make ahead of time for when you need it. After cooking leave the slice in the dish without cutting and cool, cover with tin (aluminium) foil before storing in the fridge. Then when you are ready to eat it, preheat your oven to 170c and bake covered with foil for around 20 minutes or until cooked through. 

If you are reheating leftovers, cover a slice with a dampened paper towel and cook for around 1.5 minutes or until cooked through. Note times will vary depending on your microwave.

    Great recipe. Easy to make and tastes delicious. I used Turkey bacon, which I fried a bit crispy, before mixing it in.

  2. Could I use Greek yoghurt instead of ricotta??

  3. Loved this recipe! So easy and delicious my 3yr old made the whole thing with me and ate 2 serves!!

  4. Lorissa McG

    Loved this zucchini slice! Being stuck at home with a sick toddler, I appreciated the ingredient swap suggestions as I didn’t have any ricotta on hand so I used cooking cream in the quantity suggested by Bernadette. It was so delicious – my husband & toddler gobbled up a plateful fresh from the oven.

    Love a recipe that involves one bowl you can prep everything straight into! This slice was so creamy compared to zucchini slices I’ve made on the past that are stiff and bland in comparison! Definitely my new go to zucchini slice! I added some carrot to mine to get another veggie in for the kids! Thank you for delicious slice!

  6. Best zucchini slices I’ve made to date. Super easy to prepare. Love the ricotta added to this recipe makes it super moist and extra delicious. 11 month old is loving it.

  7. Hi. Was curious if you’d know how this recipe would go if I prepared ingredients earlier in the day and then added flour and cooked?

    • I think that would be fine. It would be a great way to prep in advance for an even quicker weeknight meal! Bernadette x

  8. Hi. How can I make this gf please? Thanks!

    • Hi Megan! I haven’t tested a GF variation but a supermarket self raising blend should work fine. Thanks Bernadette

  9. Best zucchini slice recipe I have tried. So easy in one bowl. Delicious and will be keeping this one handy. I think the ricotta makes all the difference from the usual boring zucchini slices, as this was great.
