Creamy Leek and Potato Soup

Hands down the BEST creamy leek and potato soup recipe you’ll ever try – Smooth and rich, loaded with flavour and topped with crispy leeks and toasted hazelnut!

There’s nothing more comforting than a big hearty bowl of creamy leek and potato soup. It makes just the perfect starter heartwarming starter for a dinner party or for a family weeknight meal.

Why is it the best leek and potato soup recipe you’ll ever try? Because it has it all!

For best results, I recommend using Ratte, Yukon Gold or the UK-loved Maris Piper potatoes.

They all have a moist and fluffy texture, and a hint of sweetness flavour, which pairs perfectly with the delicate aroma of the leeks.

You can totally omit the toasted hazelnuts if you like, but since they take just 3 minutes to make, why not giving it a try? They add such an extra special flavour to the soup, which makes it even more interesting and puts any other soup to shame.

How To Make Leek and Potato Soup

Now, let’s talk about how beautifully mess-free this dish comes together. Really, it couldn’t be simpler to make.

Step 1: Start by heating the extra-virgin olive oil in a large saucepan, then add the potatoes, leeks and garlic, and stir-fry, stirring regularly for about 5 minutes.

Then fold in the fresh herbs and season with salt and pepper to taste.

Step 2: Pour in the vegetable stock, cover with a lid (but not entirely so that the steam can escape gently) bring to the boil.

Lower the heat and simmer until the veggies are tender and cooked through.

Step 3: Toast the hazelnuts for about 3-5 minutes in a skillet over medium-low heat. Chop them roughly and set aside until ready to serve.

Step 4: Remove the bay leaf (you can use one or two), rosemary and thyme sprigs from the pot, together with a handful of leeks and potatoes.

Step 5: Finely chop the reserved crispy leeks and cut the potatoes into tiny cubes, and set aside until needed.

Step 6: Adjust seasoning, then pour in the hot milk You can add in a tiny dollop of soured cream if you like.

Blend until smooth using a hand-held immersion blender (aka a stick blender).

The soup is now ready! Divide it into bowls, and top each one with chopped leeks, 3-4 potato cubes, chopped hazelnuts and extra rosemary and thyme leaves.

Season with extra white pepper (or black pepper if you like) if desired, and serve straight-away, nice and hot!

Can I freeze this awesome soup?

Yes, absolutely, it freezes beautifully! Once it’s ready, transfer into freezable containers, and store in the freezer up to 1 month.

Whenever you fancy, take it out from the freezer, and defrost in the fridge for 12 hours, or over the kitchen counter for about 6 hours.

Then place in a pot and reheat until nicely hot.

In the meantime, you can toast the hazelnuts and prep some crispy leeks and small potato cubes to go along with your soup.

It’s totally easy to make a plant-based soup with no cream or milk.

Simply omit the milk and pour in a little bit of extra stock if necessary.

If you want to give it a nice twist, pour in a little coconut milk. I promise it will taste equally delicious!
