This Mary Berry celery soup recipe combines celery, potato, onion, garlic and cream for a smooth, gently savoury soup. The vegetables simmer until completely tender before being blended with fresh parsley and finished with double cream.
Smooth, creamy texture is what makes this Mary Berry celery soup recipe so satisfying. Celery gives the soup its fresh, savoury character, while potato adds enough body to make every spoonful feel substantial without turning the soup heavy.
The method is straightforward, but the order matters. Onion is softened gently in butter and olive oil, celery and garlic are cooked briefly to begin building flavour, then potato and stock simmer together until the vegetables are completely tender. Fresh parsley and double cream finish the soup, keeping the flavour balanced and the texture silky. The supplied recipe serves four and uses a 20-minute simmer before blending.
Here are the main reasons this simple soup works so well.
- Potato naturally gives the soup body without needing flour or another thickener.
- Cooking the onion gently keeps its flavour mellow rather than deeply browned.
- Celery gets time to soften before the stock is added, helping its flavour blend into the soup.
- Fresh parsley goes in just before blending, bringing a fresher herbal note to the finished bowl.
- Double cream is stirred in only after blending, giving the soup a smooth, rich finish.

What Gives This Celery Soup Its Creamy Texture

The texture depends on two ingredients working together: potato and double cream. The potato cooks directly in the stock until completely tender. Once blended, its starch gives the liquid more body and helps create the creamy consistency you want.
The double cream plays a different role. Instead of providing the main thickness, it rounds out the finished soup after the vegetables have already been blended. This means you get richness without relying on a large amount of cream.
Celery itself contains plenty of moisture, so allowing the potato to become fully tender is especially important. If the potato or celery is still firm when you blend, the soup may feel coarse instead of smooth.
A few ingredients carry most of the structure and flavour.
- Celery: The main vegetable and the source of the soup’s fresh, savoury character.
- Potato: Gives the blended soup natural body and helps create a creamy texture.
- Onion: Builds the flavour base, especially when cooked slowly enough to soften without browning.
- Butter and olive oil: Form the cooking base for the onion, garlic and celery.
- Fresh parsley: Adds a herbal note just before the soup is blended.
- Double cream: Softens the savoury flavours and gives the finished soup extra richness.
Keep The Onion Soft Rather Than Browned

The first cooking stage has more influence on the finished flavour than it might seem. The onion needs about 5 minutes over medium heat, cooked in the butter and olive oil until softened but not browned.
Browning would give the onion a deeper, sweeter flavour. That can be useful in many dishes, but it would change the character of this soup. Here, the goal is a gentler base that allows the celery to remain the main flavour.
Once the onion has softened, the garlic and celery cook for another 5 minutes. You don’t need the celery completely tender at this point. It only needs to begin softening before the potato and stock are added.
This gentle start also helps the garlic avoid spending too long over direct heat. It is added only after the onion has softened, then cooks alongside the celery before the liquid goes into the pan.
Why The Vegetables Need To Become Completely Tender
After the diced potato and stock are added, the soup comes to a gentle boil. You then reduce the heat and leave it uncovered to simmer for about 20 minutes.
This stage isn’t only about cooking the vegetables enough to eat. They need to become completely tender because the recipe is designed to be blended until smooth.
A stick blender can break down cooked celery and potato very effectively, but it can’t compensate for vegetables that are still too firm. If the celery remains resistant or the potato hasn’t softened through, you may end up with a rougher texture.
You can therefore treat tenderness as the key cue before moving to the blending stage. The supplied method specifically calls for the celery and potato to be completely tender after the simmer.
Blending The Soup For A Smooth Finish
The parsley goes into the saucepan after it comes off the heat and before blending. This places the fresh herb directly into the soup rather than using it only as a garnish.
Blend with a stick blender until the mixture is completely smooth and creamy. Move the blender around the saucepan so you reach vegetables sitting near the sides and bottom instead of repeatedly blending only the centre.
Once the soup is smooth, return it to low heat. The double cream can then be stirred in, followed by salt and freshly ground black pepper to taste.
Adding the cream at this stage gives you better control over the final consistency. The vegetables have already provided the main body, so the cream becomes a finishing ingredient rather than something you depend on to thicken the soup.
How The Mary Berry Celery Soup Recipe Comes Together
This recipe follows a simple progression from flavour base to simmering, blending and finishing. Each stage prepares the soup for the next, so you don’t need complicated equipment or several pans.
You begin by preparing all the vegetables so they’re ready when needed. Butter and olive oil then form the base for gently cooking the onion. Garlic and celery follow, and the potato and stock turn everything into the main soup mixture.
After the 20-minute simmer, parsley is added and the contents of the pan are blended. The cream and final seasoning come last, once the texture is already smooth.
The finished soup can be ladled straight into bowls. Extra parsley, freshly cracked black pepper and a small swirl of cream provide the finishing touches, while crusty bread or toasted baguette slices can be served alongside.

How To Make Mary Berry Celery Soup
The method is easiest when you prepare all the vegetables before putting the saucepan on the heat. That keeps the cooking stages moving in the correct order without needing to stop halfway through.
- Prepare the vegetables. Wash the celery well, then cut it into small slices. Peel and dice the potato, chop the onion finely, and crush the garlic so everything is ready before cooking begins.
- Soften the onion. Place a large saucepan over medium heat and melt the 40g butter with the 1 tablespoon olive oil. Add the finely chopped onion and cook gently for about 5 minutes, stopping once it has softened but before it browns.
- Cook the celery and garlic. Add the crushed garlic and sliced celery to the softened onion. Continue cooking for another 5 minutes, stirring from time to time, until the celery begins to soften.
- Pour in the stock. Add the diced potato, followed by the 1 litre vegetable stock or chicken stock. Stir the contents of the saucepan together and bring the liquid to a gentle boil.
- Simmer until tender. Turn down the heat and leave the soup uncovered at a simmer for about 20 minutes. Continue until both the celery and potato are completely tender, which will allow them to blend smoothly.
- Blend with the parsley. Take the saucepan off the heat and stir in the 2 tablespoons chopped fresh parsley. Use a stick blender to puree the soup thoroughly until the texture is completely smooth and creamy.
- Finish with cream. Put the saucepan back over low heat and stir in the 100ml double cream. Add salt and freshly ground black pepper to taste.
- Serve the soup. Spoon the warm soup into bowls. Finish with chopped parsley, freshly cracked black pepper and a small swirl of cream, with crusty bread or toasted baguette slices alongside.

Notes
Serving The Soup
This soup is designed to be served warm, with a few simple garnishes rather than a complicated topping. A swirl of cream echoes the cream already used in the soup, while parsley adds a fresh visual and herbal finish. Freshly cracked black pepper gives contrast to the mellow vegetables. Crusty bread or toasted baguette slices work alongside the smooth soup and add a firmer texture to the meal. You can keep the garnish light so the celery remains the focus. The soup already contains butter, olive oil and double cream, so the finishing ingredients don’t need to be heavy.How To Avoid A Coarse Celery Soup
The easiest place for this recipe to go wrong is the transition between simmering and blending. The vegetables may look cooked on the outside before they’re soft enough to puree into a completely smooth soup.
Give the celery and potato the full simmer specified in the recipe, about 20 minutes, and check that they’re completely tender before blending. The potato in particular contributes much of the body, so firm pieces can prevent the texture from becoming evenly creamy.
It also helps to blend systematically. Keep the stick blender submerged and move it through different areas of the saucepan until you no longer encounter visible pieces of celery or potato.
The cream shouldn’t be responsible for hiding an uneven texture. By the time it goes into the saucepan, the soup should already be smooth.

Frequently Asked Questions
Can I use vegetable stock or chicken stock?
Yes. The supplied recipe gives you the choice of 1 litre vegetable stock or chicken stock. Use either one without changing the amount.
Vegetable stock keeps the ingredient list centred on the vegetables, while chicken stock will give the soup a different savoury background. Both options are part of the supplied formula.
Why does this celery soup contain potato?
The potato helps give the soup body once everything is blended. Because it becomes completely tender during the simmer, it breaks down into the liquid and supports the creamy texture.
That means the soup doesn’t rely entirely on the 100ml double cream for richness or thickness.
Do I need to brown the onion first?
No. The method specifically calls for cooking the onion for about 5 minutes until softened but not browned.
Keeping the onion pale produces a gentler flavour base and allows the celery to remain more prominent in the finished soup.
When should I add the cream?
Add the double cream after the soup has been blended. Return the saucepan to low heat, stir in the 100ml cream, and then season with salt and freshly ground black pepper to taste.
This order ensures you can make the vegetable mixture completely smooth before giving it its final creamy finish.
Why is the parsley added before blending?
The 2 tablespoons chopped fresh parsley are stirred in once the saucepan comes off the heat, immediately before blending. This distributes the parsley throughout the soup instead of leaving all of it as a garnish.
Extra chopped parsley can still be added at the table when you serve the soup.
Conclusion
This Mary Berry celery soup recipe keeps the method simple while paying attention to the stages that control texture. Gently softened onion, fully tender celery and potato, thorough blending and a final addition of double cream give you a smooth, comforting soup with fresh celery and parsley running through every bowl.
