This recipe is made by softening onions and garlic in olive oil, simmering sliced zucchini in stock until tender, blending everything into a smooth soup, then finishing with fresh basil and a touch of cream. The zucchini cooks just until soft so the flavor stays fresh, and the basil is added at the end to keep its aroma bright.
