This is a great way to put any odd vegetables floating around the bottom of your fridge to good use. The result is a deeply flavoured broth full of veggie goodness that you can heat and sip on as a broth or use in soups and sauces.

Ingredients

  • 5 cups roughly chopped vegetables (you could use a mix of a couple of chopped onions, some celery, carrots, ears of corn chopped into thirds and leeks)
  • 4 big cloves of garlic, peeled and bruised with the flat of a large knife
  • 4 tbsp olive oil
  • 1 tsp salt
  • 6 black peppercorns
  • 1 handful parsley
  • 2 sprigs thyme
  • 1 tbsp Vegemite

Method

Roast the vegetables first, then simmer everything for two hours. Drain and store the broth in jars in the fridge.

Preheat oven to 200C and combine the vegetables in a big tray (or a couple of trays). Drizzle with the oil and sprinkle with salt and pepper. Roast for 45 minutes or until everything is coloured and beginning to caramelise and even burn a bit on the edges.

Tip into a large saucepan, add the remaining ingredients and fill with water so everything is covered. Simmer for two hours. Drain and transfer the stock to a couple of big jars or containers. Keep in the fridge until needed.
