When the sun burns over the lavender fields and the cicadas chirp their songs, you know in Provence: It is time for light, nourishing food that refreshes body and mind.
The Soupe au Pistou is a culinary poem – a fragrant stew made from seasonal vegetables, refined with a basil-garlic paste, the famous pistou.
Traditionally served hot, in times of great heat it is transformed into a cold isotonic vegetable soup that supplies minerals, balances the electrolyte levels, and tastes wonderfully light.
🌞 Why Soupe au Pistou Acts Isotonically
The soup is packed with water-rich vegetables such as zucchini, beans, and tomatoes. A little fleur de sel or sea salt balances the salt levels – important during heavy sweating.
White beans provide magnesium and potassium, basil brings valuable antioxidants.
The trick: The cold preparation keeps everything wonderfully refreshing and the flavors unfold gently.
🥣 Recipe: Cold Soupe au Pistou
Ingredients (for 4 people)
For the soup:
- 2 zucchinis, diced
- 2 tomatoes, peeled, diced
- 1 potato, diced
- 100 g green beans, cut into pieces
- 100 g white beans (cooked, e.g., from a jar)
- 1 small carrot, diced
- 1 small onion, finely chopped
- 1 liter vegetable broth (lightly salted)
- 1 pinch fleur de sel or sea salt (to taste)
For the pistou:
- 1 bunch basil
- 2 garlic cloves
- 50 ml extra virgin olive oil
- 30 g grated Parmesan (optional)
- 1 small tomato, peeled and diced
- Salt to taste
Preparation
1️⃣ Cook the vegetables:
In a large pot, sauté the onion in some olive oil until translucent. Add zucchini, carrot, potato, tomatoes, and green beans. Pour in vegetable broth and let simmer gently for 20–25 minutes until everything is soft. Add the white beans shortly before the end.
2️⃣ Cool down:
Remove the pot from the heat, season with fleur de sel, and let cool completely. Then chill in the refrigerator for at least 2 hours.
3️⃣ Make the pistou:
Process basil, garlic, tomato, salt, and (if desired) Parmesan into a coarse paste using a mortar and pestle or blender. Gradually work in the olive oil until a smooth green sauce forms.
4️⃣ Serve:
Fill bowls with the cold vegetable soup, add a generous dollop of pistou on top, and stir lightly. Garnish with fresh basil.
💦 Tips for Even More Freshness
✨ Add a few ice cubes directly to the soup – a trick from the South of France in summer.
✨ Serve crispy baguette or a piece of fougasse alongside to dip into the pistou.
✨ For extra isotonic effect: Stir in a splash of lemon juice or a pinch more fleur de sel to increase electrolyte content.
