Are you tired of store-bought vegetable stock cubes with a long list of ingredients and additives that you can hardly pronounce? What if I told you that you can make your own natural and flavourful vegetable stock cubes in under 30 minutes!
In a large pot, add the olive oil and heat it up on medium heat.
Add the washed and chopped veggies. Sauté for a few minutes, add the salt and cover until the water has evaporated and the veggies are soft.
Mine took about 15 minutes on medium-low heat, but this will depend on your stove.
When the veggies are soft, transfer them into a food processor and process until you have a veggie purée. If you need to open the food processor to scrape down the sides, please do so and continue to blend until smooth.
Line a baking sheet with parchment paper and pour the purée onto the baking sheet making sure to spread it out evenly with the back of a spoon or silicone spatula.
Place the tray in the freezer and let it freeze completely.
Check on it every hour and once frozen, take the block of vegetable purée out of the baking sheet with the parchment paper, and place onto a wooden board. Cut into equal-sized squares.
Wrap each square into a 5 by 5 inch foil and transfer into a Ziplock bag. Leave the bag in the freezer and use a square any time you are making soups or stews. I like to add a piece of parchment paper onto my foil, but that's totally optional.
NOTE: if you want to use an ice-cube tray for ease, you are more than welcome to. Simply pour the puree into the tray and freeze!
