Zucchini Slice


Summertime in my garden = an abundance of zucchinis. Zucchini cakes, zucchini on the BBQ, grated zucchini for freezing and zucchini slice. Normally I bake the slice in the oven but this year we have had a really hot start to summer and with no air conditioning I didn't want to use the oven. I had read that you can bake cakes on a Weber Family Q BBQ & decided to bake the slice on our BBQ. Thumbs up - I will be definitely making this again.  

This recipe was designed specifically to be made with Bakers' Magic gluten free flour. The finished baked product will not be the same if you use another gluten free flour and you will need to adjust the recipe, particularly if the flour you're using contains rice flour.    


225 g Bakers' Magic Gluten free flour

2 tsp Baking powder

1/4 - 1/2 tsp Salt (optional)

Pepper (optional)

10 Eggs

215 g Oil

750 g Zucchini (grated) - 2 largish

225 g Carrot (grated)

1 Onion (large)

250 - 365 g Ham or bacon

225 g Cheese (grated)

extra cheese to sprinkle on top


I use a large lasagne dish (38 cm x 28 cm), if you have a large slice tray (30 cm x 20 cm) divide the recipe in half. 



Turn oven on to 180 C (fan forced) if using an oven. If using a BBQ wait until the mix is ready before turning the BBQ on.

Finely chop the onion & gently fry until it is soft & slightly golden. Let it cool slightly. 

In a large mixing bowl grate the zucchini & carrot.

Cut up the bacon/ham into smallish pieces & add to the vegetables.

Add in the grated cheese & onion. Stir the mix until well combined. 

In a separate bowl mix together the Bakers' Magic Gluten free flour, baking powder, salt & pepper.

In another bowl mix together the eggs & oil.

Add the flour mix to the vegetable mix & gently stir to combine.

Pour the egg/oil mixture onto the vegetable mix & gently stir to combine.

Pour into a greased baking dish.

Transfer to the oven & bake for ~1 hour if using the whole recipe. The time required for cooking will depend on the size of the slice & your oven. The slice will be firm to touch when it is cooked.

Cooking the slice on a Weber Family Q - I tried to keep the temperature at ~180 C, of course it varied & I increased or decreased the gas depending on the temperature (every now & then). I used a convection tray & trivet, added in a few hickory chips (we couldn't really taste the smokey flavour) and baked the slice for ~1 hour.
