Ingredients
Scale
- 1 1/2 pounds fresh asparagus, trimmed and chopped
- 1 large onion, diced
- 1 small fennel bulb, cored and diced
- 3 tablespoons olive oil
- 3 cloves garlic, chopped
- 1/2 pound Yukon Gold or yellow potatoes, thinly sliced
- 6 cups vegetable broth or water
- 3/4 teaspoon kosher salt
- 1/4 teaspoon white pepper
- 2 tablespoons fresh tarragon, chopped
- 1/3 cup fresh basil or parsley, chopped
- 1/2 cup sour cream
- 1/4 cup blanched asparagus tips for garnish
- 1 tablespoon olive oil or fennel oil for garnish
Instructions
- Heat 3 tablespoons olive oil in a large heavy-bottomed pot over medium heat. Add the diced onion and fennel and sauté for about 5–6 minutes until softened.
- Add the chopped garlic and cook for another 1–2 minutes until fragrant.
- Pour in 6 cups vegetable broth or water, then add the sliced potatoes, kosher salt, and white pepper. Stir and bring to a gentle boil.
- Reduce the heat, cover, and simmer for 15–20 minutes until the potatoes are tender.
- Add the chopped asparagus and cook for 2–3 minutes until bright green and just tender.
- Remove the pot from heat and allow the soup to cool slightly.
- Using an immersion blender or regular blender, puree the soup in batches until completely smooth while adding the fresh tarragon and basil or parsley.
- Return the blended soup to the pot and warm gently over low heat without boiling.
- Stir in 1/2 cup sour cream and mix until the soup becomes creamy and smooth.
- Serve hot and garnish with asparagus tips and a drizzle of olive oil or fennel oil.
Notes
- Do not overcook the asparagus, as it may lose its bright green color and fresh flavor.
- If using a blender, blend the soup in small batches and allow steam to escape safely.
- For a vegan version, substitute the sour cream with 1/3 cup soaked raw cashews blended into the soup.
- A small squeeze of lemon juice can brighten the flavor if the soup tastes too mild.
- Store leftovers in the refrigerator for up to 3 days and reheat gently over low heat.
