The ingredients on a cutting board and in small bowls.
  •  Leek, ads a wonderful, mild onion flavor to this soup. But it can also be replaced with yellow onion that’s been peeled and chopped. Shallots also tastes great.
  • Olive oil, or other neutral oil of choice. avocado oil is a good option.
  • Garlic, a few garlic cloves ads so much flavor to this creamy zucchini soup.
  • Zucchini, ends trimmed and chopped
  • Russet potatoes, this recipe uses russet potatoes, but any starchy variety works well for a creamy result.
  • Vegetable stock, or stock of choice for non vegan. Use organic or choose a good quality stock for maximum flavour. Homemade vegetable broth tastes amazing as well.
  • Sea salt and ground black pepper, to taste
  • Toppings (optional) A drizzle of cream, some crotons, parmesan cheese and chopped parsley.

The finished soup in a pot drizzled with cream and topped with parsley and parmesan cheese.

Hint: Top with a drizzle of cream, some croutons, parmesan and parsley. To keep this soup vegan, make sure to use vegan toppings.

Serve up this delicious, creamy zucchini potato soup with a side of some crusty bread for dipping. Use store-bought or one of these easy no knead recipes: No knead olive bread, No Knead Whole Wheat Bread or this Cranberry Walnut Bread.

Substitutions and Variations

  • Vegan – This is a vegan zucchini soup, but if you choose to top it with some cream, croutons and cheese, make sure to use a vegan alternative.
  • Potatoes – I used russet potatoes for this soup, but any starchy variety works well for a creamy result. The potatoes can also replaced with either sweet potatoes or carrots. 
  • Onion – this creamy zucchini and potato soup uses a chopped leek. Other alternatives are yellow onion or shallots.
  • Spice it up – This zucchini soup has a mild and rich flavour, if you like it spicy, add some red pepper flakes to taste or top with a drizzle of chili oil.

Some more of my favourite warming soups: Pumpkin and potato soup, Butternut squash cauliflower soup or this Lentil Quinoa Soup.

Equipment

This zucchini soup uses an immersion blender for a smooth and creamy texture. If you don’t have an immersion blender, a normal blender or even food processor can be used. Make sure not to overfill them, so the warm soup risks splashing out.

Storage

Refrigerator: First, cool down any leftover potato leek and zucchini soup. Add the soup to an airtight container, or heavy-duty ziplock bag. The soup will keep for about 4-5 days in the fridge. 

Freezer: This potato and zucchini soup can also be frozen for up to 2–3 months. Follow the directions for storing the soup in the fridge, but make sure not to fill the containers too full. The liquid will expand some when frozen, and you don’t want to risk the lid to popping off in the freezer!

Top Tip

Make sure the zucchini and potatoes are fully cooked and starting to fall apart before blending. This will ensure a smooth and creamy texture of the soup. If needed, add a little more vegetable broth or water for a thinner consistency.
