Ingredients

Scale
  • 1 pound (450g) fresh asparagus, trimmed and cut into 1-inch pieces
  • 1 medium leek, white and light green parts only, cleaned and sliced
  • 2 tablespoons unsalted butter
  • 3 cups (720ml) low-sodium vegetable or chicken broth
  • 1/2 cup (120ml) heavy cream or half-and-half
  • 1 small garlic clove, minced
  • 1 tablespoon fresh lemon juice
  • Salt and freshly ground black pepper, to taste
  • 2 cups (about 4 ounces/115g) day-old crusty bread, cut into 1/2-inch cubes
  • 1 cup (100g) shredded Gruyère cheese
  • 2 tablespoons olive oil
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder
  • Pinch of salt
  • Freshly ground black pepper, to taste

Instructions

  1. Rinse asparagus and trim tough ends, then chop into 1-inch pieces. Slice the cleaned leek thinly. Mince the garlic finely.
  2. In a soup pot, melt 2 tablespoons butter over medium heat. Add leeks and garlic, cooking gently for 5–7 minutes until soft and fragrant but not browned.
  3. Add asparagus pieces, stir for a minute, then pour in 3 cups broth. Bring to a simmer and cook uncovered for 12–15 minutes until asparagus is tender.
  4. Remove pot from heat and puree soup with an immersion blender until silky smooth. If using a countertop blender, blend in batches and return to pot.
  5. Stir in 1/2 cup cream and fresh lemon juice. Season with salt and pepper to taste. Warm gently over low heat for 3–5 minutes without boiling.
  6. Preheat oven to 375°F (190°C). Toss bread cubes with olive oil, smoked paprika, garlic powder, salt, and pepper on a baking sheet. Sprinkle shredded Gruyère evenly over bread.
  7. Bake croutons for 10–12 minutes until cheese melts and croutons are golden and crisp.
  8. Ladle warm soup into bowls and top generously with zesty Gruyère croutons.

Notes

If soup is too thick after blending, add more broth or cream to loosen. Blend hot soup carefully to avoid pressure buildup. Croutons can be made ahead and stored airtight for 2 days; re-toast before serving. For vegan version, substitute butter with olive oil, cream with coconut milk, and Gruyère with vegan cheese or nutritional yeast. Use gluten-free bread for gluten-free option.
