Essential Information

Preparation Time: 30 minutes
Servings: 6-8 portions

Required Ingredients

• 4 tablespoons unsalted butter
• 6 large shallots, thinly sliced (approximately 1 cup)
• 4 pounds fresh asparagus, trimmed and cut into 2-inch pieces
• 2 teaspoons kosher salt, plus additional for seasoning
• 2 teaspoons ground coriander
• 4 cups low-sodium vegetable stock
• Freshly ground black pepper to taste
• ¼ cup crème fraîche or sour cream
• 1 teaspoon freshly grated lemon zest
• 1 teaspoon fresh lemon juice
• Extra-virgin olive oil for finishing

Cooking Instructions

Creating the Base

Begin by heating the butter in a heavy-bottomed Dutch oven over medium heat until melted. Add the sliced shallots and sauté gently, stirring occasionally, until they become translucent and softened, approximately 5 minutes. The shallots should be fragrant but not browned.

Incorporate the asparagus pieces, kosher salt, and ground coriander into the pot. Stir the mixture for about one minute to allow the spices to bloom and coat the vegetables. Pour the vegetable stock over the asparagus, using a wooden spoon to press the vegetables down so they’re mostly submerged in the liquid.

Simmering and Blending

Bring the mixture to a gentle simmer and continue cooking, stirring frequently, until the asparagus becomes completely tender, which typically takes 8-10 minutes. Remove the pot from heat and allow the soup to cool slightly before blending.

Transfer the soup to a high-speed blender in batches, processing each portion on high speed until completely smooth and silky. Pour the blended soup into a clean bowl as you work through each batch. Once all the soup is processed, return it to the original pot and stir in 1 cup of water to achieve the desired consistency.

Preparing the Lemon Cream

While the soup stays warm over low heat, prepare the finishing cream by combining the crème fraîche or sour cream with the lemon zest, lemon juice, and a pinch of salt in a small bowl. Mix thoroughly until well incorporated.

Final Assembly

Taste the soup and adjust seasoning with additional salt and freshly ground black pepper as needed. Ladle the hot soup into individual bowls and top each serving with a generous dollop of the lemon cream mixture. Finish with a drizzle of high-quality olive oil and a final grinding of black pepper.

This soup exemplifies how simple techniques can elevate humble ingredients into restaurant-quality results. The natural sweetness of asparagus pairs beautifully with the bright acidity of lemon and the richness of cream, creating a perfectly balanced dish that celebrates spring flavors.
