Ingredients

  • 3 Tbsp unsalted butter
  • 1 large purple onion, peeled and roughly chopped
  • 5 garlic cloves, peeled and minced
  • 2 large leeks, chopped into 1 inch lengths with green tips removed
  • 3 medium sized golden potatoes, peeled and chopped into large cubes
  • 4 cups vegetable broth
  • Small pinch cayenne pepper
  • Salt and pepper, to taste
  • Fresh parsley, to serve

Instructions

  • Sauté Onion: Heat two tablespoons of butter in a large soup pot over medium-high heat, add onion and sauté for 5 minutes or until translucent.
  • Add Garlic: Stir through the minced garlic and sauté for 1 minute.
  • Cook Leeks: Add leeks and the remaining 1 tablespoon of butter and cook for 5 minutes until tender and translucent, maintaining medium-high heat.
  • Incorporate Potatoes: Add the cubed potatoes and cook for further 5 minutes, stirring well.
  • Add Liquid: Pour in the vegetable broth, it should be enough to just cover the vegetables. Season with salt and pepper.
  • Bring to Boil: Increase the heat, put the lid on, and bring to a boil. Once boiling, reduce the heat to low and simmer for 30 minutes, with the lid on, until potatoes are tender.
  • Blend Soup: Remove from the heat and blend the soup in batches in a food processor or blender until smooth and thick. Or use an immersion blender directly in the soup pot.
  • Finalize Soup: Return the blended soup to the pot. Over medium heat, stir in the cayenne pepper and season with salt and pepper once again. Bring to a boil, then remove from the heat.
  • Serve: Garnish with fresh parsley and enjoy!

Notes

  • Store: Cool the soup to room temperature, then transfer it to an airtight container. Refrigerate for up to 3-4 days.
 
  • Freeze: For longer storage, freeze the soup in airtight containers or heavy-duty freezer bags for up to 2-3 months. Leave some space for expansion when freezing in containers.
 
  • Reheat: Thaw overnight in the refrigerator if frozen. Reheat on the stove over medium heat, stirring occasionally, until hot. You may need to add a little water or broth if the soup has thickened too much during storage.
