🥕 Ingredient List
Every great soup starts with quality ingredients—they’re the building blocks that create those comforting flavours we all love. For this leek and potato soup, you’ll find most items right in your kitchen. I’ve organised everything by cooking stage to make your prep work a breeze.
For the Soup Base
- Leeks (3 medium): About 500g or 1.1lb total weight. Look for firm, crisp leeks with bright green tops. Trim off the tough dark green parts and root end before slicing.
- Potatoes (500g/1.1lb): Use floury potatoes like Maris Piper or King Edward for that perfect creamy texture. Peel them before chopping.
- Onion (1 large): Roughly 200g or 7oz. Brown or white onions both work beautifully here.
- Garlic (2 cloves): Fresh garlic gives the best flavour. If you only have garlic paste, use 1 teaspoon instead.
- Unsalted butter (50g): That’s about 3½ tablespoons. Using unsalted lets you control the seasoning perfectly. For dairy-free, swap with 3 tablespoons of olive oil.
For Flavour & Liquid
- Vegetable stock (1 litre): That’s 4 cups or 34 fluid ounces. Homemade stock is fantastic, but a good quality stock cube dissolved in boiling water works brilliantly too.
- Fresh thyme (3 sprigs): The woody stems add wonderful aroma. If you don’t have fresh, use 1 teaspoon of dried thyme leaves.
- Bay leaves (2): These dried leaves add subtle depth. Remove them before blending—they’re not meant to be eaten!
- Sea salt and black pepper: To taste. I prefer coarse sea salt and freshly ground black pepper for the best flavour.
To Finish & Serve
- Double cream (100ml): That’s about ⅓ cup plus 1 tablespoon. This adds luxurious richness. For a lighter version, use single cream or crème fraîche.
- Fresh chives or parsley (small bunch): Chopped finely for garnish. These fresh herbs add colour and a bright finish.
Don’t worry if you need to make swaps—cooking should be flexible! If you’re avoiding dairy, coconut cream makes a lovely alternative to double cream. And if leeks are tricky to find, extra onions with a handful of spring onions work surprisingly well.
👩🍳 Step-by-Step Instructions with Pro Tips
How do I prepare the vegetables properly?
Step 1: Prepare your vegetables
Start by thoroughly washing your leeks. Slice them thinly, using both the white and pale green parts. The dark green tops can be saved for stock another time. Peel and dice your potatoes into even, bite-sized pieces.

Step 2: Cook the leeks
Melt a generous knob of butter in a large saucepan over medium heat. Add your sliced leeks with a pinch of salt. Cook gently for 8-10 minutes until they’re soft and sweet, but not browned.

Step 3: Add potatoes and stock
Stir your diced potatoes into the softened leeks, coating them in the buttery mixture. Pour in enough vegetable or chicken stock to just cover the vegetables – about 1 litre usually does the trick.
When will I know it’s cooked through?
Step 4: Simmer until tender
Bring everything to a gentle boil, then reduce to a simmer. Cover with a lid and cook for 15-20 minutes until the potatoes are completely tender when pierced with a fork.

Step 5: Blend to perfection
Remove the pan from heat. Using a stick blender, carefully purée the soup until completely smooth. For extra silkiness, you can pass it through a fine sieve.

Step 7: Serve with style
Ladle your velvety soup into warm bowls. Top with a drizzle of cream, some chopped chives or crispy bacon bits, and a grinding of black pepper.
The beauty of this recipe lies in its simplicity. Each step builds flavour gradually, creating that comforting, homely taste we all love. Take your time, trust the process, and you’ll have a bowl of pure comfort ready in under an hour.
🔄 Recipe Variations & Serving Suggestions
What if you want to mix things up a bit?
The beauty of this leek and potato soup is how adaptable it is. Once you’ve mastered the basic recipe, you can easily tweak it to suit your mood or what’s in your cupboard.
How can you add extra flavour?
For a Mediterranean twist, stir through a handful of chopped sun-dried tomatoes at the end – their sweet, intense flavour works wonders. If you fancy some heat, a pinch of red pepper flakes added while sautéing the leeks gives a lovely spicy kick. For a vegan version, simply swap the butter for olive oil and use vegetable stock instead of chicken stock.
What’s the best way to serve it?
A bowl of this comforting soup deserves proper accompaniments. Crusty bread for dipping is non-negotiable in my book. Fresh herb garnishes like chopped chives or parsley add a bright, fresh finish. For something really special, try ladling the soup over a bed of creamy polenta – it’s a game-changer.
How should you store and reheat leftovers?
Let the soup cool completely before transferring it to an airtight container. It’ll keep in the fridge for 3-4 days. For longer storage, freeze portions for up to 3 months. When reheating, do it gently on the hob over a low heat, stirring occasionally. If it’s thickened in the fridge, just add a splash of water or stock to loosen it back up.
Don’t be afraid to make this recipe your own – that’s half the fun of cooking!
🔬 Why This Recipe Works
Ever wondered why some soups taste flat while others sing with flavour? The Hairy Bikers’ approach gets it right every time, and here’s why.
The gentle start makes all the difference
Instead of rushing, we sweat the leeks slowly in butter. This gentle cooking releases their natural sugars without browning them, creating a sweet, mellow base. That initial patience builds layers of flavour that you simply can’t achieve with a quick fry.
Potatoes do double duty
Starchy potatoes like Maris Pipers break down beautifully when simmered. They thicken the broth naturally, giving it that luxurious, creamy texture without needing loads of cream. The starch acts as a natural emulsifier, creating that velvety mouthfeel we all love.
Timing is everything
Adding the stock after the vegetables have softened properly means they cook evenly. The simmering process extracts maximum flavour from every ingredient, melding them together into something greater than the sum of its parts. That’s the magic of proper soup-making technique.
Trust these methods—they’re what transform simple ingredients into a truly comforting bowl of soup.
❓ Frequently Asked Questions (FAQ)
Can I make this soup ahead of time?
Absolutely! This leek and potato soup actually tastes better the next day. The flavours have more time to meld together. Just cool it completely before storing in the fridge for up to three days. Reheat gently on the hob when you’re ready to serve.
Is it freezer-friendly?
Yes, this soup freezes beautifully. Portion it into airtight containers, leaving a bit of space at the top for expansion. It’ll keep well for about three months. Thaw overnight in the fridge before reheating.
What if I don’t have double cream?
No worries—single cream or crème fraîche work just as well. For a dairy-free version, try a splash of oat or almond milk. The soup will still be wonderfully creamy.
Why did my soup separate?
If your soup looks a bit curdled, it’s usually from overheating the dairy. The trick is to stir the cream in right at the end, off the heat. If it does separate, a quick blitz with a stick blender often brings it back together beautifully.
