By Marcus Samuelsson |


This subtly-herbed soup makes excellent use of the season’s abundant summer squash and fragrant basil, and is excellent served hot or cold. Plus you can’t go wrong with a roux!

Heat 2 tablespoons of the oil in a large saucepan or stockpot, add zucchini and onion. Saute for 5 minutes or until onions are translucent and zucchini is just tender.

Add stock, bring to a boil, reduce heat and partially cover and cook for 25 minutes. Add basil during the last 5 minutes of cooking.

Mix the remaining 1 1/2 tablespoons oil and flour together into a paste. Remove 1 cup of simmering stock and whisk in the roux until smooth. Add back into soup, stir until thickened.

Remove soup from heat to a blender and puree until smooth. Taste and season with salt and pepper. Add lemon juice, and garnish with scallions. Serve with extra lemon slices.
