This spring soup has a wonderful creaminess and tang from Greek yogurt, and a nice, bright note from lemon juice. The homemade croutons are a snap.


Unsalted butter

1 Tbsp

Uncooked leeks

4 large, white and light green parts only, split, cut into 2-inch pieces and rinsed well

Jarred minced garlic

1½ tsp, divided


4 pound(s), trimmed and cut into 2-inch pieces

Reduced sodium chicken broth

6 cup(s)

Reduced-calorie whole wheat bread

3 slice(s), cubed

Cooking spray

2 spray(s)

Kosher salt

1¼ tsp, divided (or to taste)

Lemon zest

1 tsp

Plain low fat Greek yogurt

½ cup(s)

Fresh lemon juice

1 Tbsp, or more to taste

Fresh mint leaves

2 Tbsp, minced (for garnish)


  1. Preheat oven to 375ºF.
  2. Melt butter in large pot over medium heat. Add leeks and cook, stirring frequently, until softened, abour 5 minutes. Add 1 teaspoon garlic and cook 1 minute. Add asparagus and broth and bring to boil. Reduce heat and simmer until asparagus is soft, 12 to 15 minutes.
  3. Meanwhile, spread bread cubes in a single layer on a baking pan; coat with cooking spray and sprinkle with 1/4 teaspoon salt. Bake, stirring once halfway through, until croutons are crisp, about 10 minutes; remove from oven and toss with lemon zest and 1/2 teaspoon remaining garlic.
  4. Add yogurt, lemon juice and remaining 1 teaspoon salt to soup; puree in pot using an immersion blender (or puree in batches using a regular blender). Heat soup through (do not let boil); serve sprinkled with croutons and garnished with mint.
  5. Serving size: 1 1/2 cups soup and 1/3 cup croutons


Fresh tarragon or chives are great substitutes for the mint.
