Leek and Potato Soup Ingredients

To make this classic winter comfort food all you need is just  a bunch of  ingredients:

  • potatoes
  • leeks
  • fresh herbs (rosemary, bay and thyme)
  • garlic
  • vegetable broth
  • extra-virgin olive oil ( or butter)
  • toasted hazelnuts
  • fresh milk

Using the right ingredients is crucial for making the most delicious leek and potato soup recipe.

Opt for organic ingredients whenever possible, don’t skip on the fresh herbs, and use high-quality extra-virgin olive oil (which is an even better option than butter if you ask me). 
 
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.

Start by heating the extra-virgin olive oil in a large saucepan, then add leeks, garlic and potatoes, and stir-fry, stirring occasionally for about 5 min, Then fold the fresh herbs and season to taste.

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.

In the meantime, heat a large skillet and toast the hazelnuts for about 3-5 mins, until lightly browned, then cut into halves and set aside until ready to serve.

Adjust seasoning, pour in the hot milk, then blend until smooth using a hand-held immersion blender.

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

Creamy Vegan Leek and Potato Soup

If you wonder how complicated might be to make a dairy-free leek and potato soup, fear not.

It’s totally easy to make a plant-based leek and potato 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 in your creamy vegan potato leek soup. I promise it will taste equally delicious!

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.
