The secret to a delicious zucchini and potato soup that's light and much creamier than it looks

A simple soup that hides a clever little culinary trick.

No need for cream to get a soup that delicately coats the spoon. The real trick is in the potato, whose starch swells during cooking and naturally adds body to the broth. Simple, but rather clever.

The zucchini thus retains its mild, vegetal flavor, particularly pleasant in September when it's still in season. The result remains light, velvety, and very flavorful, with just enough olive oil to round out the tastes without turning this everyday soup into an overly rich dish.

Just a few ingredients are enough to prepare a rich and fragrant cream soup.

For four bowls, there's no need to multiply the ingredients. The entire recipe relies on the balance between the zucchini, which brings freshness and sweetness, the potato, responsible for adding creaminess, and a seasoning subtle enough not to overpower the vegetables. A good broth then ties everything together.

• 600 g of zucchini
• 1 medium potato, approximately 150 to 180 g
• 1 yellow onion
• 600 to 700 ml of vegetable stock
• 1 tablespoon of olive oil
• 1 small pinch of nutmeg
• Cell
• Freshly ground pepper
• A few fresh herbs to serve, optional.

Six easy steps to get a truly velvety soup without making it sticky

The principle is intentionally simple: give the potato a little head start, then cook the zucchini just for the necessary time. This method avoids boiling them endlessly. When blending, a few seconds are then enough to combine the textures without overworking the potato starch.

• Peel the potato and keep it whole, then peel and slice the onion.
• Gently sauté the onion in olive oil for 3 to 4 minutes, without letting it brown.
• Add the whole potato and the stock, then simmer covered for about 10 minutes.
• Incorporate the chopped courgettes and continue cooking for 10 to 12 minutes, until the potato is tender throughout.
• Briefly blend the soup until it has a smooth, coating consistency, adding a little more stock only if it seems too thick.
• Season with salt, pepper and a pinch of nutmeg, then serve with a few drops of olive oil and, if desired, fresh herbs.

Small variations to transform the same soup without complicating the recipe

Once you've mastered this basic recipe, a few changes are all it takes to give your creamy soup a whole new character. The idea isn't to add ten extra ingredients, but to tweak just one element at a time. This is often how a very simple soup can suddenly transform into a delightful bistro starter.

• For added freshness: add a few basil leaves just before blending. Their aroma works particularly well with the sweetness of the zucchini.
• For a more robust flavor: replace some of the olive oil with a small knob of butter added after cooking.
• For a more vegetable-based soup: add a small white part of a leek with the onion, without increasing the amount of potato.
• To add contrast: finish each bowl with a few toasted pumpkin seeds or golden croutons. The crunch works particularly well with a very smooth soup.
• To enhance the flavors: add a few drops of lemon juice when serving. A very small amount is all it takes to add depth without making the soup overly lemony.

A very modest saucepan that nevertheless manages to give the impression of much more

This is probably what makes this recipe so appealing: the creaminess doesn't necessarily come from the cream. When the potato starch absorbs water during cooking, it naturally contributes to thickening the liquid. You simply need to avoid blending unnecessarily for several minutes.

Served piping hot with a few croutons, herbs, or a drizzle of olive oil, this soup has everything you could want in an early autumn dinner: few ingredients, minimal dishes, and plenty of comfort. And no one has to immediately reveal where the famous cream is hiding.
