Why This Recipe Works
- This creamy asparagus, leek and pea soup highlights three classic spring vegetables in one smooth, flavorful bowl.
- Frozen peas work beautifully, so the recipe is convenient as well as fresh-tasting.
- The soup comes together quickly, making it a practical choice for lunch, dinner or meal prep.
- It can be made ahead, reheated easily and frozen successfully when the cream and lemon juice are added after thawing.
The Ingredients
- Asparagus is the main ingredient in this soup. Thinner spears cook quickly and blend smoothly, but thicker asparagus will also work. They may simply need a little more time to become tender.
- Leeks bring a mild onion flavor that pairs especially well with spring vegetables. Because leeks often hold grit between their layers, rinse them carefully before cooking.
- Frozen peas add sweetness, color and body. If very fresh green peas are available, they can be used, but frozen peas are reliable and convenient.
- Chicken or vegetable broth forms the base of the soup. Chicken broth adds savory depth, while vegetable broth keeps the recipe vegetarian.
- Fresh thyme gives the soup a clean herbal note without overpowering the vegetables.
- Flour helps thicken the soup and creates a smooth, creamy consistency.
- Lemon juice brightens the flavor and balances the richness.
- Heavy cream adds just enough body and softness without making the soup heavy.
- Cayenne pepper adds a subtle warmth that rounds out the finished dish.
How To Make This Recipe
- Start by trimming the woody ends from the asparagus. Cut the tender stalks into 1-inch pieces. Set aside about ½ cup of the nicest asparagus tips to use as a garnish.
- Trim the leeks, keeping only the white and light green parts. Slice them in half lengthwise and rinse thoroughly under running water, separating the layers slightly to remove any sand. Cut the cleaned leeks into ½-inch slices.
- Melt 1 tablespoon of butter in a large pot or Dutch oven over medium heat. Add the reserved asparagus tips and 1 tablespoon of water. Cover and steam until bright green and almost tender, about 2 minutes.
- Remove the lid and sauté for about 1 more minute, or until the tips are fully tender. Transfer them to a plate, sprinkle lightly with coarse salt and reserve for serving.
- Add the remaining 2 tablespoons of butter to the pot. When melted, stir in the leeks, thyme and 1 teaspoon of salt. Cook for 5 to 7 minutes, stirring occasionally, until the leeks are soft and just beginning to brown.
- Sprinkle in the flour and cook for 1 minute, stirring constantly. This step removes the raw flour taste and helps create a silky soup.
- Add the remaining asparagus, broth and 2 cups of water. Bring the mixture to a boil, then reduce to a simmer. Cook for 5 to 7 minutes, or until the vegetables are tender.
- Stir in the frozen peas and remove the pot from the heat.
- Puree the soup in batches in a blender until completely smooth. Return the soup to the pot and stir in the lemon juice, cream and a pinch or two of cayenne pepper.
- Taste carefully and season with additional salt and lemon juice as needed. Serve warm, garnishing each bowl with the reserved asparagus tips.
Expert Tips
- Clean the leeks thoroughly. Leeks can hide sand and grit between their layers. Slice them lengthwise and rinse under running water before chopping so the finished soup stays smooth and clean.
- Blend hot soup safely. Hot liquid expands quickly in a blender. Fill the blender no more than halfway, cover it securely and hold a kitchen towel over the lid while blending.
- Season at the end. This soup needs enough salt to bring out the natural sweetness of the asparagus, leeks and peas. Taste after adding the cream and lemon juice, then adjust until the flavor is balanced.
- Adjust for asparagus thickness. Thin asparagus cooks quickly, while thicker spears may take a few extra minutes. The vegetables should be tender before blending.
