Chilled Summer Squash Soup With Yogurt, Mint, and Sourdough Croutons Recipe
  • Meal

    Soup

  • Cusine

Ingredients

For the Soup:

3 tablespoons butter

1 medium bunch green onions, white and green parts, chopped

3 medium garlic cloves, chopped

Kosher salt and freshly ground black pepper

3 pounds mixed summer squash , chopped into medium pieces

About 3 cups water

1 cup plain yogurt, low fat or full fat

1/4 cup chopped fresh mint leaves plus additional, for serving

 

For the Croutons

Half a medium loaf of sourdough bread, cut into a 1/2" dice

1 tablespoon extra virgin olive oil

1/2 teaspoon dried herbs, such as herbes de provence

Directions

Adjust oven rack to middle position and preheat oven to 375 degrees F (see note). Heat butter in a large heavy-bottomed saucepan or Dutch oven over medium heat until melted. Add green onions and garlic and season to taste with salt and pepper. Cook, stirring occasionally, until onions and garlic begin to sweat but do not brown, about 5 minutes. Add summer squash and season to taste with additional salt and pepper. Cook, stirring occasionally, until squash begins to sweat but does not brown, about 7-10 minutes. Add enough water so that squash is almost, but not fully, covered, about 3 cups. Cover saucepan partially and lower heat to medium-low. Simmer until squash is just tender, about 12 to 15 minutes. While soup is simmering, prepare the croutons. In a large bowl, toss cubed bread with olive oil, salt and pepper to taste, and dried herbs, if using. Turn out onto a rimmed baking sheet and bake, stirring occasionally, until well-browned and crisp, 10 to 12 minutes. Remove from oven and let cool. Use a hand blender to blend soup until mostly smooth. Alternatively, blend soup in a blender in two batches. Add yogurt and mint and blend until totally smooth (again, working in batches if using standard blender), about 1 minute. Strain soup through fine mesh strainer if desired. Let soup cool at room temperature for one hour, stirring occasionally. Transfer to refrigerator and let cool, stirring occasionally, until well chilled, about 45 minutes. Check soup for seasoning, adding more salt, pepper, yogurt or mint to taste. Serve in bowls, garnished with additional chopped mint and a handful of croutons.
