⭐⭐⭐⭐⭐ Absolutely delicious!!! … and so filling. I also added celeriac, yum!!! – Alyssa
This easy vegetable soup is one of those cheap and easy to make meals that is perfectly satisfying for the cooler weather, and makes a large batch that keeps getting better with each bowl of leftovers.
If you’re not a fan of blended soups, then I think you’ll like this one. The texture is closer to a stew in that it’s chunky and thick which helps make it feel more satisfying. It has so much flavour thanks to all the vegetables, and a generous seasoning of herbs.
This is the perfect dinner when you want something healthy and full of veggies but still comforting and hearty. It’s a great vegetarian and vegan alternative to a comforting slow cooked beef stew. In fact, I’ve even made this vegetable soup while camping!
There really is nothing quite like a homemade soup from scratch and this recipe is so easy and full of basic, low cost ingredients that it’s sure to become a favourite.
Key Ingredients
While it might look like there are a few ingredients needed for this soup, they are all simple and easy to find ensuring you soup has maximum flavour.

Note all ingredients and their quantities are laid out in the recipe card at the bottom of this post.
- Carrots, onions, celery and garlic – combined, these make the ultimate flavour base get’s our soup off the ground.
- Tomato paste – is cooked down with the vegetables to provide a deep, rich flavour to the soup.
- Dried herbs – I like to use a combination of dried thyme, oregano and basil for that Italian style flavour to this soup, but you can use a mixed herb blend as well.
- Potatoes, parsnip and swede (rutabaga) – I like to use this combination of root vegetables to bulk out the soup and the starch from the potatoes helps with thickening the soup. You can replace the parsnip and swede with an additional potato if you want. Sweet potato would also be a nice substitute.
- Soup mix – Soup mix can be purchased in the supermarket for less than $2 and is a mix of legumes and grains, usually split peas, barley, lentils. If you can’t find it you can use either all barley or half barley, half lentils.
- Vegetable stock – I use a combination of stock and water for the soup but you can use all stock or all water if you like. Make sure to use a good quality brand as this helps ensure a stronger flavour through the soup. I also always like a salt reduced stock so I can control the seasoning myself.
- Salt and pepper – seasoning is so important to the flavour of this soup. Be generous with the salt and this will enhance the flavour (only if you’re using salt reduced stock), and be sure to taste it before serving to make sure the flavour is just right.
- Frozen peas – I like to finish off my soup by stirring through some frozen peas at the end for some extra colour and texture.
💡Most Australian supermarkets sell a vegetable soup pack, which is a pre-packaged combination of potatoes, onion, celery, carrot, parsnip and swede which is what you need for this recipe.

Step-by-Step Instructions
Like all good soups, this one starts with the sauteing of onions, carrots and celery. We are also adding a couple of cloves of garlic for extra flavour. Once the onions are soft, add in the tomato paste and the herbs and continue to sauté until the tomato paste starts to caramelise and everything smells delicious.
This step of letting the herbs and tomato paste cook down a little bit before adding in the stock really helps with developing the complex flavour of this soup.


Add in the rest of the chopped vegetables and the soup mix.
I like using soup mix as it provides a good variation to the soup, with the lentils helping to create a nice thick, hearty texture, and the barley making it full of fibre and ensuring it keeps you feeling satisfied.
Finally, add your stock and water and bring to the boil.


Turn down and simmer for 45 minutes until the vegetables are soft and the barley is tender. Add the frozen peas and stir through the soup to heat them.
Season with salt and pepper to taste. You can serve this soup on its own, topped with some fresh parsley, or with some crusty bread to sop up all the liquid from the bowl leaving nothing behind.


Storage Instructions
This vegetable soup will last up to 5 days in the fridge making it perfect for meal prep so that you always have something healthy on hand for lunch or dinner.
You can also freeze the soup in individual portions for up to 3 months if you’re not keen on eating leftovers all week.
When reheating the soup, if you find it has become too thick, you can add an additional ¼ cup of water per serve to thin it out a bit and stretch the leftovers a little further.
Recipe FAQs
Yes! If you have fresh herbs on hand, you can absolutely use them. As a general rule, use three times the amount of fresh herbs compared to dried. Add fresh herbs towards the end of cooking for the best flavour.
Definitely! This soup tastes even better the next day as the flavours develop. See above for more information around storage.
Yes! This soup is very flexible. You can add in zucchini, green beans, sweet potato, spinach or whatever you have in the fridge that needs using up. Just adjust the cooking time as needed depending on the vegetables you add.
As this soup contains barley, no it is not gluten free. If you want to make it gluten free, then you’ll need to use a soup mix that does not contain barley or just use a combination of split peas and dried lentils.
