Ingredient Notes and Substitutes

  • Self-raising flour: this can be substituted for ½ cup of plain flour and ½ teaspoon of baking powder. Or for a gluten-free alternative ½ cup of ground almonds and ½ teaspoon of baking powder. You can also use a GF flour.
  • Riced cauliflower and broccoli: You can rice your broccoli and cauliflower by blitzing them into rice-sized pieces in a food processor... or check your local supermarket freezer for broccoli and cauliflower rice.
  • Grated cheese: I like to use strong, tasty cheddar in this recipe.
  • Milk: You can use any plant-based milk if you do not wish to use cow's milk.
  • Corn kernels: Frozen or canned corn kernels are fine for this recipe.
  • Salt and Pepper: If you are making this for a young child for baby led weaning skip the salt. If not season to taste!

How to make a veggie slice

Below are illustrated step-by-step instructions to make my Vegetable Slice Recipe, if you prefer just the written instructions then head straight to the printable recipe card below.

Prep: Preheat your oven to 180 degrees Celsius (360 Fahrenheit)

Prep your tin: I cook this veggie slice in a slice tin. Mine is approximately 20cm x 30cm. I spray the tin with oil, then I line it with baking paper. I line it in a way that the paper drapes over the long edges of the tin, this allows me to easily lift out the slice when it is cooked. You can also make this slice in a loaf tin, the thicker you make the slice the longer the cooking time might be.

Step one: In a large mixing bowl whisk the eggs, milk and flour. Don't worry if it's a bit lumpy, the lumps bake out.

Step two: Stir through the remaining ingredients: Cauliflower, Broccoli, Onion, Cheese, and Corn Kernels.

Step three: Pour the veggie slice mix into your slice tin. Bake at 180 degrees for 20 minutes or until the slice has risen, all the egg is cooked and the slice is golden brown on top.

Top Tips

Here is how you can make this vegetable slice recipe perfectly every time!

  • Cook Time: If you are baking a thin slice like the one I have pictured, the cooking time will be approximately 20 minutes, if you have decided to make your veggie slice in a smaller tin, the cooking time will be longer, in a loaf tin it can take up to 40 minutes.
  • Cool a little before slicing: When the veggie slice is piping hot from the oven it can fall apart a little when you slice it. If you let it cool a bit, it will firm up and be easier to slice.
  • Everything is better with Bacon: This recipe is absolutely with a little added bacon! Add around 100g of chopped bacon when you add the veggies and you won't regret it. The bacon does not have to be cooked first it will cook in the slice just fine.

      Made for my 2.5yo twins. Had no cauli but added 100g champagne ham. They liked it but think I should have blitzed the onion as may not have been small enough as I’m a rubbish dicer haha

    2. Hi Stacey,

      I am looking to make this recipe but I am really not a fan of corn.

      Could I replace the quantities with any other veg of choice are are there some that you would say wouldn't work.

      Thanks
