Ingredients for Sweet Potato Leek Soup

Here’s what you need for this easy vegan soup:

  • Leek. Choose a large, fat leek. Or, if you can’t find a large one, two small ones work just fine.
  • Garlic. For plenty of allium flavor.
  • Spices. I season this soup with crushed chili flakes, smoked paprika and fresh thyme leaves.
  • Sweet potatoes. You’ll want to remove the skin for a super smooth texture to your soup.
  • Vegetable broth. Use low-sodium store-bought broth or make your own!

How to Serve Leek Soup

This recipe is great for a light lunch. To round it out for dinner, serve it with crusty bread, pita, or naan. You could also pair it with this Buckwheat Harvest Salad w/ Kabocha, Broccoli and Pecans for a filling meal.

Storing Leftovers

This is a good recipe for vegan meal prep. You can store the soup for up to four days in an airtight container in the fridge. It also freezes well. Just let the soup cool fully, then transfer it to a freezer-safe container and keep it in the freezer for up to six months. You can reheat the soup from frozen or let it thaw overnight in the fridge and reheat servings on the stove or in the microwave.

Toppings for Creamy Vegan Sweet Potato Soup

If you want to dress up your soup with some toppings, go for it. I like adding something creamy, crunchy, or fresh on top. Here are some easy topping ideas for pureed soup:

  • Croutons or crunchy chickpeas
  • Crispy tofu
  • Vegan sour cream or coconut yogurt
  • Fresh herbs
  • Chili flakes, harissa, or chili crisp
  • A drizzle of olive oil

  1. I made this as meal prep for my evenings and loved it! Wouldn't change a thing – the smoked paprika gives it a beautiful smokey note, it's rich and creamy, and the leek pairs amazingly with the leek. I added some crispy chickpeas on top and couldn't have asked for a better dinner.
