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.

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.
