A velvety, creamy asparagus and leek soup topped with crispy, nutty Gruyere cheese croutons, perfect for a fresh and comforting spring meal.

Ingredients

Scale
  • 1 pound (450 g) fresh asparagus, trimmed and cut into 1-inch pieces
  • 2 large leeks, white and light green parts only, cleaned thoroughly and sliced thin
  • 3 tablespoons (45 g) unsalted butter
  • 2 garlic cloves, minced
  • 4 cups (960 ml) low sodium vegetable broth
  • 1/2 cup (120 ml) heavy cream (optional, can substitute with full-fat coconut milk for dairy-free)
  • Salt and freshly ground black pepper to taste
  • 1 cup (100 g) Gruyere cheese, grated
  • 4 thick slices of day-old rustic bread, cut into 1-inch cubes
  • 2 tablespoons (30 ml) olive oil
  • 1 teaspoon fresh thyme, finely chopped (optional)

Instructions

  1. Trim the tough ends of the asparagus and cut into 1-inch pieces. Clean the leeks thoroughly to remove any grit, then slice thinly.
  2. Melt the butter in a large heavy-bottomed pot or Dutch oven over medium heat. Add the sliced leeks and cook gently, stirring often, until soft and translucent, about 8 minutes.
  3. Add minced garlic and cook for another minute until fragrant, being careful not to brown the garlic.
  4. Add the asparagus pieces and stir to combine. Pour in the vegetable broth and bring to a gentle simmer. Cover partially and cook for 15 minutes or until asparagus is tender but still bright green.
  5. Remove the pot from heat and blend the soup until silky and smooth using an immersion blender or countertop blender in batches.
  6. Stir in the heavy cream, then season with salt and freshly ground black pepper to taste. Warm gently over low heat for 2–3 minutes without boiling.
  7. Heat olive oil in a large skillet over medium heat. Add bread cubes and toast until they start to crisp, about 3 minutes.
  8. Sprinkle grated Gruyere evenly over the bread cubes and toss gently until the cheese melts and turns golden and crispy, about 3–5 more minutes. Stir in fresh thyme if using.
  9. Ladle the hot soup into bowls and generously top with the crispy Gruyere croutons. Serve immediately.

Notes

Use firm asparagus stalks for best flavor. Clean leeks thoroughly to remove grit. Avoid browning garlic to prevent bitterness. Blend soup carefully to avoid splatters. Toast croutons on moderate heat to prevent burning. For dairy-free, substitute cream with coconut or cashew cream and Gruyere with nutritional yeast or vegan cheese. Day-old bread works best for croutons. Soup can be made ahead and stored in fridge; keep croutons separate until serving.
