A delicious, warm, flavourful meal, this Slow Cooker Potato Leek Soup is a great option for dinner after a busy day. Don't have a slow cooker? You can also make it in the Instant Pot if you prefer.

How to Make Slow Cooker Potato Leek Soup

To get started, you'll want to prepare the potatoes and set them aside. Peel them, wash them and then chop them into approximately 1/2 inch cubes. Place them in a bowl to the side.

To prepare the leeks, it's a little bit more involved but certainly not difficult. Here's an excellent video that shows you exactly how to get them ready for the soup.

Once the leeks are prepped, place them in a fry pan with a bit of butter and cook until they are soft but not browned. Remove from the pan and place in the slow cooker.

Now fry the garlic in the same pan until it becomes fragrant and browned then add it to the slow cooker as well.

Add the bay leaves and the potatoes.

Now pour in the stock, place the lid on the slow cooker and cook on low for 8-10 hours until the potatoes are falling apart and the leeks are soft.

When done, remove the lid and, using an immersion hand blender, blend the soup until it becomes a smooth puree. Add in the cream, stir and serve hot!

That's it!

Happy cooking!

Ingredients
 

  • 2 tablespoons butter
  • 8 leeks washed of all the grit and white/pale green parts chopped
  • 1 tablespoon minced garlic
  • 6 cups Russet potatoes peeled and sliced into 1/2 inch cubes
  • 7 cups chicken broth
  • 2 bay leaves
  • 1 cup heavy cream

Toppings

  • minced green onions
  • nutmeg

Instructions
 

  • In a frying pan over medium heat, fry the leeks in the butter until soft, trying not to brown any of the leeks in the process. You simply want to cook them until they are soft. Add in the garlic, saute until fragrant, around 1-2 minutes.
  • Place the leeks into a slow cooker then add the potatoes,chicken stock and bay leaves.
  • Cook on low for 8-10 hours until the potatoes are falling apart and the leeks are soft.
  • Remove the bay leaves and use an immersion blender to puree until smooth if desired. You can also take a potato masher to the soup to break up the potatoes if you like a chunkier soup.
  • Stir in the cream until mixed through completely.
  • Serve and enjoy! Top with green onions or nutmeg if desired.
