Ingredients
Vegetables & Herbs
- 2 bunches asparagus (about 2¼ pounds/1 kg), bottom ends trimmed
- 2 medium yellow onions, chopped
- 3 cloves garlic, peeled and smashed
- Handful fresh herbs, such as thyme, dill or basil (optional, for garnish)
Liquids & Dairy
- 3 tablespoons unsalted butter
- 6 cups low-sodium chicken broth
- 2 tablespoons freshly squeezed lemon juice (from one lemon)
- ½ cup shredded Parmigiano-Reggiano
Seasonings
- Salt
- Freshly ground black pepper
Instructions
- Sauté the aromatics: Melt the butter in a large pot over medium heat. Add the chopped onions and smashed garlic cloves and cook, stirring frequently, until they become soft and translucent, about 8 minutes. Take care not to brown them by reducing the heat if necessary.
- Prepare the asparagus: Cut the tips off one bunch of asparagus and set these aside for garnish. Cut the remaining spears along with the second bunch into ½-inch (13-mm) pieces.
- Cook the soup base: Add the chopped asparagus pieces to the pot, excluding the reserved tips. Pour in the chicken broth along with 1 teaspoon of salt and ¼ teaspoon of freshly ground black pepper. Bring the mixture to a boil, then cover the pot and reduce the heat to low. Let it simmer for about 30 minutes, until the asparagus and onions are very tender.
- Prepare the garnish: Meanwhile, bring a small pot of salted water to a boil. Cook the reserved asparagus tips for a few minutes until they are tender-crisp. Drain and immediately transfer them to a bowl of ice water to stop the cooking and retain their bright green color. Drain again and set aside.
- Blend the soup: Use an immersion blender to purée the soup until completely smooth. Alternatively, blend the soup in batches using a standard blender and return it to the pot. Bring the puréed soup back to a gentle simmer, then stir in the freshly squeezed lemon juice and shredded Parmigiano-Reggiano. Taste and adjust the seasoning with additional salt and pepper if needed. To achieve a thicker consistency, simmer uncovered until you reach your desired thickness.
- Serve and garnish: Ladle the finished soup into bowls, then top each serving with the cooked asparagus tips, extra Parmigiano-Reggiano, fresh herbs if using, and a sprinkle of freshly ground black pepper. Enjoy warm.
Notes
- Use low-sodium chicken broth to control salt levels more easily.
- The reserved asparagus tips make a beautiful and tasty garnish, offering a contrasting texture.
- For a vegetarian version, substitute chicken broth with vegetable broth.
- You can adjust the thickness of the soup by simmering longer after blending to evaporate excess liquid.
- Fresh lemon juice brightens the soup and adds a lovely zesty note—add it at the end to preserve its flavor.
