Ingredients

Lentils

  • 4 cups (32oz/1 litre) regular vegetable broth, or low-sodium*
  • 1 1/2 cups (9.8oz/280g) red split lentils

Vegetables

  • 1 large red onion, peeled and quartered
  • 3 large carrots, trimmed not peeled
  • 1 large white potato, Yellow Dutch or Russet, leave peel on or off
  • Half a medium-large sweet potato, leave peel on or off
  • 4 stalks celery, trimmed
  • 2 cups water
  • 2 vegetable bouillon cubes
  • 1 tsp Vegemite, see notes
  • Salt & pepper, to season
  • Small handful fresh parsley, roughly chopped

Instructions

Lentils

  • Use a large soup pot, enough to hold up to 6-8 cups of liquid (48oz-64oz or 2 litres).
  • To the pot, add lentils and pour in broth.
  • Bring to a boil, stirring occasionally.
  • Once boiling, reduce heat to low and keep at a simmer.

Vegetables

  • Roughly cut vegetables into large chunks so they can break down easier in the food processor.
  • Pulse each vegetable separately in the food processor until chopped into small chunks/diced. Tip: Process both types of potatoes together. The veggies are chopped separately due to them breaking down at varying rates.
  • After you finish one vegetable, add it to the soup.
  • Once all veggies are in the pot, pour in the 2 cups of water and stir to combine.
  • Add bouillon cubes, Vegemite if using and season with salt and pepper. Mix well.
  • Increase heat to high and bring to a boil.
  • Once boiling, reduce heat to low and keep at a simmer.
  • Simmer for 15-20 minutes, stirring occasionally until vegetables are tender and soup has thickened.
  • Taste test and adjust seasonings if needed with more salt and pepper or add one more bouillon cube if desired.
  • Remove from heat.
  • Sprinkle each serving with chopped parsley.
  • Serve immediately and enjoy!

Notes

  • Low-Sodium Broth: If using low-sodium broth, just taste test and adjust the seasoning before serving. You can add one extra stock cube for added flavour and salt if needed.
 
  • No Food Processor? Simply dice your vegetables or roughly chop them into small chunks. Try to keep all the vegetables close in size to ensure even cooking.
 
  • Chicken or Beef Broth: Replacing the vegetable broth with either chicken or beef broth adds even more flavour. Use regular or low-sodium, adjust salt if needed after taste testing.
 
  • Vegemite: A suitable alternative is Marmite. If you don’t have either, omit it from the recipe and add one more vegetable stock cube if additional flavour is needed after taste testing.
 
  • Store: Cooled soup in an airtight container in the fridge for 4-5 days.
 
  • Freeze: Cooled soup by portioning into individual serving size freezer-safe containers. Label with the date and freeze up to 3 months.
 
  • Thaw & Reheat: Thaw frozen soup overnight in the fridge. Reheat on stovetop over low-medium heat or microwave in a safe container, until warmed.
