Pure vegetable soup is so simple, quick to make and satisfying. What’s more, there’s no chicken stock, milk or cream. Instead, it’s made with some good French butter (or olive oil for vegans) and extra fresh seasonal vegetables. It’s chunky, healthy, low in calories and the ultimate flavour is fresh aromatic herbs added at the end of cooking.

What are the Main Classifications of French Soups?

According to Larousse Gastronomique, there are a few major classifications under soup. However, over time, things have simplified in modern French cooking and so both soupe and potage are used to mean the same thing.

  • Soupe (from ‘souper’, meaning supper): rustic soup or broth served on slices of bread;
  • Potage: (from the word ‘pot‘): liquid preparation served hot or cold at the start of a meal;
  • Velouté (from the word, ‘velours’ meaning silk): soupe/potage thickened with a roux of flour and butter and blended with egg. For examples, see my recipes for Crème Dubarry and this Mushroom Cappuccino;
  • Consommé: liquid soup made with beef stock or clarified chicken broth.

In English, there are National soups too – such as Cullen Skink in Scotland. For more French soups, I have more to come!

This is such a French classic. Apart from a few different vegetables, there’s no need to change anything from Raymond Blanc’s original recipe for fresh vegetable soup in my favourite cookbook, “Mange“. When I first received a signed copy of it as our engagement present in 1996, I was secretly terrified at French cuisine, as the French gourmet recipes for guests all looked complicated.

Years later, however, I realised with a little bit of confidence, the gourmet French recipes were much easier than they looked – and this pure vegetable soup can’t be any easier!

What is Pure Soup Made Of?

Unlike soups that use chicken or vegetable stock (such as this pumpkin and ginger soup), this pure soup relies on the fresh vegetables themselves with the addition of just water. It’s very like my sweetcorn soup with bell pepper, as I use only the cobs to make the natural stock. Here the root vegetables are sweated first in good quality unsalted butter with salt and pepper added. There is no milk or cream used.

There are two secrets to this recipe:

  1. Use the freshest of vegetables and herbs; and
  2. Respect the short cooking time of just 15 minutes.

Chunky Vegetable Soup

These days, I normally blend soups to a smooth consistency (see all my soup recipes). So serving this soup to the family as chunky seems almost D-A-R-I-N-G. Is this perhaps life in the fast lane?

I served this to my French (Corsican) parents-in-law recently, as they’re total soup addicts like myself. Madeleine gave it a confirmed nod of approval but she seemed surprised.  They had soup with chunks in it growing up in Corsica. You know what? Me too! I remember the chunky Scotch Broth (Janice has a good recipe at Farmersgirl Kitchen) with lamb and good old Lentil Soup (Christina has another good recipe with barley at Christina’s Cucina) with a large ham shank, when I was growing up in Scotland.

Somehow, going back to the “bits in it” is somehow satisfying and, while not a thick, hearty soup, the freshness of the herbs makes this a welcome starter.

What is the Secret to Making Good Soup?

In a nutshell, the secret to making good soup is to use only good, fresh ingredients. Make your pure vegetable soup fresh and vibrant.

  • I know it’s tempting to use up these veggies at the bottom of the fridge that may be starting to wilt – but please don’t! Gone are the days I made veggie soup with the sorry leftovers.  Fresh peas from the pod and French green beans in summer? Use them. Peas are brilliant in this. As is broccoli or cauliflower – add tiny florets. Use extra fresh vegetables, there’s no need for any pre-made vegetable, chicken or beef stock. The butter gives that added French touch and brings out the taste of both the veggies and herbs.
  • Please use good quality butter. Don’t use low-fat spreads or spreadable butter. It’s not the same!
  • Don’t chop up your vegetables too far in advance. They will not only lose their flavour but also their vitamin content. So prepare this as close as possible to when you will serve.
  • Don’t keep the soup on the boil. This will not just destroy the vitamin and mineral content but above all, the vegetable textures and flavours. Instead, once initially boiled, immediately lower the temperature and keep it at a simmer.
  • Fresh aromatic herbs: Add the chopped fresh herbs at the end of cooking to preserve their flavour and vitamins. Chervil is best if you can find it, otherwise tarragon is good. Flat-leafed or frisée parsley is excellent as it contains a lot of vitamin C.
    For much more, see the French Market Produce page on Aromatic Herbs.

What Can I Add to Vegetable Soup to Make it Taste Better?

As I say above, the secret to this soup is using good quality and the freshest ingredients. However, if you feel it still lacks a bit of flavour, then here are some ideas. Just add at the end of cooking:

  • Add an extra dollop of butter in the last minute of cooking;
  • Liquidise the soup and add a little cream or crème fraîche;
  • Add a garnish pinch of smoked paprika or piment d’espelette to serve;
  • Add a squeeze of fresh lemon juice. The acidity will help to bring out the flavours;
  • For a touch of luxury, add a little saffron. This is a natural flavour enhancer and so will bring out the taste of each vegetable.

What Herbs Go Well in Soup?

I love fresh parsley in this vegetable soup, along with chervil or tarragon. However, other fresh herbs that are great to add at the end of cooking are freshly chopped chives, basil, lovage and sorrel.

Quick to make and healthy, this vegetable soup recipe is perfect for any time of year, using the freshest seasonal vegetables and fresh aromatic herbs. What's more it's low in calories.


  • 25 g (1oz) butter unsalted (or 2 tbsp olive oil for vegans)
  • 1 onion finely chopped
  • 1 medium carrot finely sliced
  • 1 medium leek outer leaves discarded, finely sliced
  • 1 small turnip (French navet) or potato finely chopped into cubes
  • 1 tbsp french beans chopped (see notes)*
  • 1 litre / 1.75 pints water
  • 2 ripe tomatoes chopped
  • 2 tbsp fresh peas from the pod (if fresh in Spring - optional)
  • 1 tsp salt
  • freshly ground pepper according to taste
  • 1 tbsp fresh tarragon or chervil finely chopped (stalks removed)
  • 1 tbsp fresh parsley finely chopped (stalks removed)


  • In a large pan, gently melt the butter over a medium heat (don't allow it to brown). Sweat the chopped onion, carrot, and leeks gently for about 5 minutes.
  • Add the turnip/potato, water, salt and pepper. Bring briefly to the boil, skimming off any impurities (foam) then immediately reduce the heat, cover but allow a little air to escape. Simmer for up to 15 minutes or until the vegetables are softened.
  • Add the tomatoes, peas (if using), and chopped fresh herbs. Cook for no more than a minute. 


Inspired by Raymond Blanc's Fresh Vegetable Soup with Chervil recipe in his book, Mange. If you prefer your soups smooth, then liquidise with a hand blender or food processor.
Vegetable Alternatives: Adapt vegetables according to what's in season. As I personally don't like celery, I have replaced one stalk of it with a small turnip (French navet). Fresh peas from the pod are delicious, as are mini broccoli or cauliflower florets.
Stock: vegetable or chicken stock can be used in place of the water but I find it's not necessary when using the fresh herbs.

    • Glad to hear you’re enjoying it, although I do hope you’re not on a diet for too long! Bon courage x

  1. Still cold today. Soup made – delicious and enough for tomorrow too. Will make this again.

  2. Recipe printed. Just what we need on this cold and miserable day. Simple is good for me.

  3. 5 stars
    Now this is the sort of cooking I wish more people in the US would pick up on! Quick, easy, nutritious, inexpensive and totally delicious! Why are they still buying CANS and mixes for soup? UGH. Most are so ridiculously high in sodium, may contain BPA from the cans and are simply not nutritious 🙁 Thanks for linking to my lentil soup, too, Jill.

    We’ll try to share our simple, healthy recipes with those who will have them 🙂

    • Agreed. Totally with you, Christina. This is a real treat – and the fresher the ingredients, the more you can actually taste them and it’s bursting with vitamins too. And 15 minutes cooking time is absolute MAX.
