Ingredients
For the Vegetable Soup
- 1 tbsp olive oil
- 1 medium onion, finely chopped
- 1 leek, trimmed and sliced
- 2 medium carrots, diced
- 1 medium potato, peeled and diced
- 1 celery stick, finely sliced
- 1 small parsnip, diced
- 1 litre vegetable stock
- 1 bay leaf
- Salt and freshly ground black pepper, to taste
- 2 tbsp fresh parsley, finely chopped
How to Make Delia Smith Vegetable Soup Recipe
- Prepare the vegetables: Peel and chop the onion, carrot, potato, and parsnip into small even pieces. Slice the leek and celery so the vegetables cook evenly and release their natural flavour into the soup.
- Heat the base: Warm the olive oil in a large saucepan over medium heat. Add the chopped onion and leek, cooking gently for about 5 minutes until softened but not coloured.
- Add the remaining vegetables: Stir in the diced carrot, potato, celery, and parsnip. Cook for another 3 to 4 minutes, stirring occasionally so the vegetables begin to soften.
- Add the stock: Pour in the vegetable stock and add the bay leaf. Bring the soup to a gentle boil, then reduce the heat to a steady simmer.
- Simmer the soup: Cover the pan partially with a lid and cook for 25 to 30 minutes until the vegetables are tender and the flavours have blended beautifully.
- Season and finish: Remove the bay leaf, then season the soup with salt and freshly ground black pepper. Stir in the chopped parsley just before serving.

Tips for the Best Vegetable Soup
How can I make the soup more flavorful?
Allow the vegetables to cook gently in the oil before adding the stock. This step builds a deeper flavour base and enhances the sweetness of the vegetables.
Can I blend the soup for a smoother texture?
Yes, you can blend part or all of the soup using a hand blender if you prefer a smoother consistency while still keeping some texture.
Which vegetables work best in this soup?
Root vegetables such as carrots, potatoes, and parsnips provide natural sweetness and body. You can also add peas, cabbage, or courgette for extra variety.
How do I keep the vegetables from becoming mushy?
Cut the vegetables into similar sized pieces and simmer the soup gently rather than boiling it rapidly.
