This easy leek and potato soup is creamy, comforting, and packed with flavour. Perfect for a cosy lunch or light dinner, and great for meal prep!
This leek and potato (or leek and tattie if you come from the North East of Scotland!!) soup recipe is one of my go-to soups and gets made over and over again...it's based on a recipe I found on a BBC Good Food website a few years ago. It's delicious, classic comfort food, that's very quick to prepare and cook. How about making some homemade bread or savoury scones to enjoy along with it - see Serving Suggestions below.
Tips
- Bacon lardons - if you can't get lardons, use unsmoked streaky or back bacon instead - chop up 8 rashers of streaky or 4 to 6 rashers of back bacon. Leave out the bacon for a vegetarian version.
- Dairy-free option - use olive oil instead of butter, and oat, almond or coconut milk instead of semi-skimmed milk.
- Low-carb option - swap the potatoes for cauliflower to reduce carbs while keeping the creamy texture.
- Toppings - try topping with grated cheese or croutons. If you want to make your own croutons, preheat the oven to 220C/200C fan/gas 7, then cut 3 slices of white bread into approx. 1.5cm cubes. Put the bread cubes into a bowl, then add 3 tbsp rapeseed oil and a sprinkle of sea salt flakes. Mix well, then spread the bread cubes out into an even layer on a baking tray and bake in the oven for 10 minutes until golden, turning halfway through. Any leftover croutons will keep in an airtight container for a couple of days for you to enjoy with the rest of the soup.
- Alternative soup texture - if you prefer a chunky soup, keep some of the diced potatoes whole, rather than blending everything.
- This leek and potato soup recipe can easily be adapted to make less or more.
FREQUENTLY ASKED QUESTIONS
No - peeling is optional! Leaving the skins on adds more fibre and texture, but if you prefer a smoother soup, peeling is recommended.
Keep in an airtight container in the fridge for up to 4 days. Reheat gently on the hob or in the microwave, adding a splash of water or milk, if needed.
Yes - cool completely and freeze for up to 3 months. Thaw in the fridge overnight before reheating.

Try it with crusty bread, grilled cheese, or chilli cheese scones.
There is already bacon lardons in this recipe. However, you could leave this out and stir in cooked chicken, crispy pancetta, or even white beans for alternative protein options.

How to make this Leek and Potato Soup
Ingredients

- 1.2 litres vegetable stock (made using 2 stock cubes or pots)
- 2 bay leaves
- 0.5 tsp salt
- 0.25 tsp freshly ground black pepper
- 300ml milk (I use semi-skimmed)
Instructions

- Melt the butter in a large soup or casserole pot (I use our 24cm casserole pot) and add the bacon lardons. Fry for 2 to 3 minutes until the bacon starts to colour.
- Add the leeks and potatoes and stir round to coat in the butter and bacon.
