Zucchini Slice Ingredients

Many zucchini slices tend to use gluten flours and milk. This one doesn’t. Here’s what we use instead:

  • Rice Flour – a small amount of white rice flour is used to thicken and bind the zucchini slice together. You will notice that the slice doesn’t rise significantly, which creates a nice, even slice that is held together really well.
  • Zucchini – a great vegetable for baking, zucchini provides both nutrition and moisture to recipes. It is really important though to squeeze as much excess water from your grated zucchini as possible though as it can affect the final texture of the slice.
  • Eggs – with 5 eggs in this recipe, it might seem like a lot, but the structure, color, protein and flavour they provide are very important to this recipe.
  • Cheese – any type of cheese will do for this recipe, just make sure it’s grated/shredded. You can use less or substitute it for lactose free cheese if required.
  • Onion, bacon & corn – adding flavour, nutrition and texture, these ingredients can be substituted as per taste – just try and use similar textures and stick to about 1.5 cups in total.

Why Is My Zucchini Slice Mushy?

You won’t get a mushy zucchini slice if you drain the grated zucchini well first. Due to the high water content of zucchini, it’s very important to make sure that once grated, you drain as much excess water from the zucchini as possible.

Waste not, want not though – the watery-green goodness that you drain can be used in smoothies, soups or pasta sauces that you may also be cooking up.

This gluten free zucchini slice recipe will last in the fridge for up to 3 days.

It can be reheated in the microwave, oven or air-fryer, but is equally as delicious cold from the fridge.
