There are soups you make because you need to fill up your belly. And then there is this one: the zucchini soup you make because you actually want it. Creamy, full of flavor and with a touch of cumin that gives it just a little something extra compared to other zucchini soups. With leek, potato and Parmesan, this soup owes its creamy texture entirely to the vegetables themselves (no cream needed).

The secret? Cumin

Most zucchini soup recipes taste mild and neutral. This one does things differently. Cumin gives a flavor boost that adds just the right amount of character to this creamy zucchini soup. For the perfect balance, I’ve added Italian seasoning, black pepper and onion powder. Always taste after blending and adjust with extra salt and/or pepper.

Tips for the best texture

No roux or cornstarch needed, the potato acts as a natural thickener in this zucchini potato soup. Cook for 15–20 minutes until the potato and zucchini are completely soft, then blend until smooth for a silky, creamy zucchini soup.

Make it thicker: add an extra potato or simmer uncovered for a few extra minutes.
Too thick: add hot water one spoon at a time.
Do you peel zucchini for soup? No. the skin blends in completely and adds extra nutrients. Only with very large, older zucchini can the skin turn slightly bitter.

Storing and freezing zucchini soup

Store the cooled soup in an airtight container in the refrigerator to keep it for 3 days. In the freezer, it should last up to 3 months. Divide into portions before freezing for easy weekday meals. Reheat in a pan over low heat and add a splash of water if the soup is too thick.

Variations, zucchini soup as a meal

Chickpeas: add a can of chickpeas for extra protein and a hearty soup. Ideal if you want a meat-free meal that keeps you full. A great way to turn this into a complete vegetarian zucchini soup that works as a main course.
Greek yoghurt: stir a tablespoon of Greek yoghurt through the soup instead of Parmesan for a fresher and lighter taste.
Frozen zucchini: no fresh zucchini on hand? Frozen zucchini works perfectly in soup. Add it when frozen. Soup is forgiving and the zucchini softens quickly.

Ingredients

Portions

ZUCCHINI SOUP

25 ml olive oil

125 g potato, 1 potato

750 g zucchini, 2 pieces

250 g leek, 1 leek

125 g yellow onion, 1 yellow onion

2 garlic cloves

1 veggie stock cube

4 g ground cumin, (1⅓ tsp)

3 g onion powder, (1 tsp)

1.5 g black pepper, (½ tsp)

1500 ml boiled water

25 g Parmesan cheese, grated

1 g Italian seasoning

Tips

Sauté the vegetables gently before adding the water. This helps release the flavors and gives the soup more depth.

Let the soup cook long enough until the potato is soft. This makes the texture creamy after blending. The longer you blend, the smoother and lighter the texture becomes.

Always taste the soup at the end. Add extra pepper, salt, or herbs if needed.

Serve the soup hot right away and optionally garnish with extra Parmesan cheese.

Veelgestelde vragen

Why does my zucchini soup taste bland?

Zucchini soup has a mild flavor and needs seasoning. Add extra pepper, salt, ground cumin, garlic, stock, or Parmesan cheese for more flavor.

Is zucchini soup good for weight loss?

This recipe is naturally low in calories. The creaminess comes from the potato and Parmesan rather than heavy cream. Skip the Parmesan or replace it with a tablespoon of Greek yoghurt to make it even lighter.

What does zucchini soup taste like?

Mild, creamy and subtly savory with a warmth from the cumin that sets this recipe apart. The leek adds a gentle sweetness and the Parmesan gives a rich, salty depth. It is comforting without being heavy.
