Mary Berry Leek And Potato Soup Recipe

Today’s Mary Berry Leek And Potato Soup Recipe came into my kitchen thanks to my aunt. She has always been a huge Mary Berry fan and never misses a chance to share one of her favourite recipes with me.

One weekend, she made a big pot of creamy leek and potato soup for lunch. The smell alone had everyone heading straight to the table.

After one bowl, I knew I wanted to make this creamy Mary Berry leek and potato soup version at home.

What I love most is how simple it is. A few everyday ingredients like leeks, potatoes, onion, garlic, stock, and cream come together to make something warm and satisfying.

If you enjoy homemade soup that feels comforting without being heavy, this recipe is well worth trying. It is easy enough for a weekday meal but still feels special when served with crusty bread.

This classic British leek and potato soup has that same cosy feeling many people look for in dishes like Lancashire Hotpot. Simple food, made well, never really goes out of style.

How Does This Mary Berry Leek And Potato Soup Taste

This soup tastes rich, creamy, and wonderfully comforting from the first spoonful.

After making it a few times and comparing both vegetable stock and chicken stock versions, I found the vegetable stock gives a lighter and cleaner flavour.

The chicken stock version feels a little deeper and more savoury.

The leeks bring a gentle sweetness that works beautifully with the soft potatoes.

The onion and garlic sit quietly in the background and help build flavour without taking over.

The double cream adds a smooth finish and makes the soup feel extra cosy.

I also like that it is not heavy or overly rich.

Each spoonful feels balanced, warming, and satisfying.

Served with crusty bread, it tastes like the sort of homemade meal many of us grew up enjoying on a chilly day.

Mary Berry Leek And Potato Soup Ingredients

4 tbsp Butter (about 60g) – I usually use salted butter from brands like Lurpak or Anchor. It melts into the vegetables and gives the soup a rich, comforting base. Butter also helps soften the leeks and onion without adding any strong flavour.

2 Medium Leeks, sliced – Leeks are the heart of this soup. I use only the white and light green parts as they are softer and sweeter. They bring a gentle onion-like flavour that makes the soup taste classic and homemade.

1 Medium Onion, finely diced – A simple onion adds extra depth and sweetness as it cooks. It blends into the soup beautifully and helps build a fuller flavour without standing out too much on its own.

3 Garlic Cloves, minced – Fresh garlic gives a light savoury note that works well with the leeks and potatoes. Three cloves add enough flavour to notice, but not so much that it overpowers the rest of the ingredients.

1 Pinch Salt – A small pinch of salt helps bring all the flavours together. It may seem like a tiny amount, but it makes a real difference to the overall taste of the finished soup.

1 Pinch Black Pepper, plus extra for serving – Black pepper adds a little warmth and balance. I like to finish each bowl with an extra twist of freshly ground pepper for a bit more flavour.

½ tsp Celery Salt – This adds a subtle savoury edge that works particularly well with potatoes. It is a small ingredient, but it helps give the soup a more rounded and comforting taste.

750g Potatoes, peeled and diced – I often use Maris Piper or King Edward potatoes. They break down nicely during cooking and create the thick, creamy texture that makes this soup so satisfying.

1.2 Litres Vegetable Stock or Chicken Stock – Stock forms the main liquid base of the soup. Vegetable stock keeps it light, while chicken stock gives a slightly richer flavour. I use whichever I have in the cupboard.

4 tbsp Double Cream – Double cream gives the soup its silky finish and extra richness. It softens the flavours and makes every spoonful feel smooth without making the soup overly heavy.

Crusty Bread, to Serve (Optional) – A slice of warm crusty bread is perfect alongside this soup. It is ideal for dipping and turns a simple bowl of soup into a more filling and comforting meal.

Optional Garnishes

• Reserved cooked leek
• Reserved cooked potato
• Extra double cream for drizzling
• Chopped chives or finely sliced spring onions

How To Make Creamy Mary Berry Leek And Potato Soup

Step 01 – Prepare the Vegetables

Trim the leeks and discard the dark green leafy tops. Slice the white and light green portions into thin rounds. Finely dice the onion and mince the garlic cloves. Peel and dice the potatoes into bite-sized chunks.

Step 02 – Start the Soup Base

Place the butter in a large saucepan over a low to medium heat. Once melted, add the sliced leeks, diced onion and minced garlic.

Step 03 – Season and Soften

Add the salt, black pepper and celery salt. Cook gently for about 7 minutes, stirring occasionally, until the vegetables are soft and translucent. Avoid browning or colouring the vegetables; the aim is to soften them while developing a gentle, sweet flavour.

Step 04 – Reserve Leek for Garnish

Once the leeks have softened, remove a small spoonful of the cooked leek mixture and set it aside if you plan to garnish the finished soup.

Step 05 – Add Potatoes and Stock

Add the diced potatoes to the saucepan. Pour in the vegetable stock or chicken stock until the potatoes are fully covered. Stir well to combine all the ingredients.

Step 06 – Simmer Until Tender

Bring the soup to a boil, then reduce the heat and simmer gently for about 20 minutes. Cook until the potatoes are completely tender and can easily be pierced with a fork.

Step 07 – Reserve Potato for Garnish

Check that the potatoes are fully cooked. Remove a few potato pieces and set them aside if you would like to use them as a garnish later.

Step 08 – Blend the Soup

Using a hand blender, blend the soup to your preferred consistency. Blend until completely smooth for a silky texture, or leave it slightly coarse for a more rustic soup. The finished soup should remain fairly thick.

Step 09 – Add the Cream

Stir in the double cream and mix thoroughly until fully incorporated. Warm through gently without boiling. Finally stir the soup well with a whisk until well combined.

Step 10 – Serve and Garnish

Ladle the soup into serving bowls. If desired, top with the reserved leek and potato. For a richer presentation, drizzle a little extra cream over the surface, sprinkle with freshly ground black pepper and finish with chopped chives or spring onions.

Step 11 – Enjoy

Serve immediately with crusty bread on the side.

Little Secrets for Creamy Leek And Potato Soup at Home

Give the leeks a proper wash – I always rinse them thoroughly because soil often hides between the layers and can end up in the soup.

Choose floury potatoes – Maris Piper potatoes are my usual choice. They blend smoothly and help create a thick, creamy texture.

Take your time with the vegetables – Let the leeks and onion soften gently. If they brown, the soup loses some of its delicate flavour.

Blend with care – Hot soup can splash. I blend in short bursts and keep the blender head fully submerged.

Stir in the cream last – Adding cream at the end keeps the soup silky and stops it from becoming too heavy.

Always taste before serving – A small pinch of salt or pepper can make a surprising difference to the finished bowl.

Keep extra stock nearby – If the soup thickens more than expected, a splash of warm stock brings it back perfectly.

Finish with fresh black pepper – I never skip this step. Freshly ground pepper adds a lovely final touch and lifts the flavour.

What To Serve with This Leek And Potato Soup

A thick slice of crusty bread is always my first choice because it soaks up the creamy soup beautifully.

Cheese scones also work well and add a lovely savoury touch.

For a more filling meal, serve the soup alongside a simple ham sandwich or a toasted cheese sandwich.

A small green salad can bring freshness and balance to the richness of the soup.

If I’m serving guests, I often put out warm bread rolls and a little butter on the table. It keeps things simple but still feels welcoming and satisfying.

Things That Can Go Wrong with This Mary Berry Leek And Potato Soup

• Not washing leeks properly: Dirt can stay hidden between layers.
• Browning the vegetables: This changes the delicate flavour of the soup.
• Using too little stock: The soup may become overly thick.
• Undercooking potatoes: They need to be completely tender before blending.
• Boiling after adding cream: This can affect the smooth texture.
• Skipping seasoning: Even simple soups need proper seasoning to taste their best.

Leftover Storage and Reheating Guide

Leftover Storage

Allow the soup to cool completely before storing. Place it in an airtight container and keep it in the fridge for up to 3 days.

For longer storage, freeze it in suitable containers for up to 3 months. Leave some space at the top because the soup expands slightly when frozen.

Reheating

For chilled soup, heat gently in a saucepan over medium-low heat, stirring occasionally. If frozen, thaw overnight in the fridge before reheating.

Add a splash of stock or water if the soup has thickened too much. Warm through until hot but avoid vigorous boiling.

Mary Berry Leek And Potato Soup Recipe FAQs

Can I make this soup ahead of time?

Yes. In fact, many people find the flavour develops nicely after sitting overnight in the fridge. Make the soup, cool it completely, and store it in an airtight container. Reheat gently before serving and add a little extra stock if needed.

Which potatoes are best for this recipe?

Floury potatoes such as Maris Piper or King Edward are excellent choices. They break down easily during cooking and help create a naturally creamy texture without needing lots of cream.

Can I freeze this soup?

Yes, it freezes very well. Let the soup cool completely before placing it into freezer-safe containers. Freeze for up to three months and thaw overnight before reheating.

Can I make it without cream?

Absolutely. The potatoes already create a creamy texture. The cream adds richness, but the soup still tastes lovely without it.

Why is my soup too thick?

Potatoes absorb liquid as they cook and cool. Simply add a little extra stock while reheating until you reach the consistency you like.

Can I use chicken stock instead of vegetable stock?

Yes. Chicken stock adds a deeper savoury flavour and works very well with leeks and potatoes. Either option gives excellent results.

How do I make the soup smoother?

Blend it for longer using a hand blender. Make sure the potatoes are fully cooked before blending, as this helps achieve a silky texture.

Can I leave some chunks in the soup?

Of course. Blend only part of the soup if you enjoy more texture. Many people like a slightly chunky version for a rustic feel.

What garnish works best?

Reserved leek, potato pieces, chopped chives, spring onions, black pepper, and a small drizzle of cream all work beautifully. They add colour and extra flavour without much effort.

Is this soup suitable for vegetarians?

Yes, as long as you use vegetable stock instead of chicken stock. Check all ingredients carefully if cooking for someone with specific dietary needs.

Can I use frozen leeks?

Fresh leeks give the best flavour and texture, but frozen leeks can work if needed. Allow them to thaw slightly and cook them gently with the onion and garlic.

How long does the soup last in the fridge?

When stored properly in an airtight container, the soup should stay fresh for around three days. Always reheat thoroughly before serving.
