Wash the zucchini and cut it into medium-sized cubes.

Peel and finely chop the onion and garlic. Heat the olive oil in a pot, then add the onion and garlic. Fry for a few minutes, stirring occasionally.

Add the chopped zucchini to the pot and pour enough water to cover about ¾ of the contents. Simmer on low heat until tender, about 10-15 minutes. Add more water if needed or drain excess before blending.

Once the zucchini is soft, blend everything with a hand blender. Season with salt and pepper to taste and mix well.

Serve on a plate.
