Fry the zucchini and garlic in a saucepan with the oil.
After about 5 minutes, deglaze with the broth. Add enough broth to the saucepan so that the zucchini cubes are barely covered. This can be also more than the 400ml, depending on the size of the zucchini.
Then season with thyme and nutmeg and simmer for about 15 minutes.
Then puree everything and stir in the vegetable cream. Depending on how creamy you want it to be, use a little more or less of it.
Season to taste and serve with some toasted bread.
