Ingredients you will need

- Zucchini – the star ingredient! Choose firm, dark green zucchinis and be sure to weigh them, as adding too much zucchini will make your slice soggy. There is no need to drain the excess liquid from the grated zucchini, unless they are overly watery. I add a combination of coarsely and finely grated zucchini for added texture, but either will work.
- Bacon – I use middle bacon, but you can also use shortcut or streaky bacon, or even pre-cut bacon pieces. Alternatively, chopped ham or even chorizo can be used instead. For a vegetarian version, add some vegetarian “bacon”, crumbled feta or sun-dried tomatoes instead.
- Eggs – are used to bind the mixture. Use large, free-range eggs at room temperature.
- Self-raising flour – gives structure and a little rise to the slice. Gluten-free flour can be used, if required. If you don’t have self-raising flour, you can make your own by mixing 1 teaspoon of baking powder into every cup of plain flour.
- Cheese – use cheddar (tasty) or any other type of hard cheese, like Colby. A mix of cheddar and parmesan adds a little extra bite. Be sure to grate your own, as it will melt into the slice better than pre-packaged shredded cheese.
- Olive oil – for moisture and flavour. Choose a light, mild-tasting olive oil, or any other mild oil.
Step by step instructions
Step 1 – Make the batter;
Place all of the ingredients together in a bowl and stir to combine. ** If frying the bacon and onion, do this first.
Step 2 – Bake;
Place the batter into a lined, 20 x 27cm baking tin and bake until golden brown on top and completely cooked through.
Expert tips
- In this recipe, the bacon is added directly to the batter, uncooked. Sometimes (if I have time), I will fry the bacon and onion in a pan before adding it to the mixture. Either way tastes great, but the fried bacon does add extra flavour, richness and texture.
- Be sure to accurately weigh and measure the ingredients, to prevent the slice from becoming too mushy.
- Add some additional veggies; grated carrot, corn or sliced spring onions can be added to the mixture before baking.
- Bacon can be swapped for ham, chorizo or even some finely chopped leftover chicken. Or for a vegetarian version, add vegetarian “bacon” or leave the meat out entirely. Tofu, sun-dried tomatoes, goats’ cheese or feta can be used in its place.
- Add a little grated parmesan for extra cheesy flavour.
- Top the slice with some freshly sliced tomato before baking.
- For zucchini muffins, divide the mixture into muffin trays instead. The cooking times will vary, depending on the size of your muffin tray.
- The slice will be very soft when first removed from the oven, so leave it to cool in the tray for around 20 minutes before attempting to remove it. Otherwise, it may fall apart.
FAQs
Mushy zucchini slice is caused by excess liquid in the mixture, or by too little flour being added. Be sure to measure the ingredients accurately. Due to the high water content of zucchini, the slice can become soggy and mushy if too much grated zucchini is used. I advise weighing the zucchini before grating, for best results. Choosing smaller, firm zucchinis will help, as they hold less water.
Cooked and cooled zucchini slice can be wrapped (individual slices or whole) and kept in an airtight container in the freezer for up to 3 months. Thaw at room temperature or in the fridge overnight before serving hot or cold.
Zucchini slice will last in the fridge in an airtight container for 3-4 days.
Zucchini slice can be enjoyed hot or cold as a quick on-the-go breakfast, brunch, lunch or dinner. It also makes a great lunchbox option or an after-school snack. For lunch or dinner, serve it warm with a side salad, potato salad or with your favourite steamed veggies. You can also top it with your favourite tomato sauce or chutneys!
To reheat zucchini slice, place individual pieces in the microwave for around 1 minute, or until heated through. A whole slice can also be covered and reheated in the oven, until steaming hot. Or pop individual pieces in an air fryer at 160 C for around 5 minutes, or until heated through.
