Peel the zucchini and potatoes. Cut them into cubes of about 2 cm. Peel and finely chop the onion.
Cook the onion
Heat the olive oil in the saucepan over medium heat. Add the chopped onion and cook for 2 min without browning.
Add the vegetables
Add the zucchini and potato cubes to the saucepan. Stir well to coat them with the onion.
Add the broth
Add the vegetable broth until the vegetables are covered. Bring to a boil over high heat.
Tip · If you use a bouillon cube, make sure it's vegetable-based (no meat or poultry flavoring).
Simmer
Lower the heat to keep a gentle boil. Cook for 15 min, stirring now and then.
Check if it's done
Poke the potatoes with the tip of a knife: it should slide in easily. If not, cook 2-3 min longer.
Blend the soup
Skim the surface if needed. Blend the soup in a blender or with an immersion blender until smooth.
Tip · For a creamier texture, you can mash some of the vegetables with a fork before blending everything.
Adjust the seasoning
Taste and add salt and pepper as you like. If the soup is too thick, add a little hot water.
