Ingredients for Lemony Roasted Asparagus Soup
• Asparagus: Provides the fresh, grassy flavor and forms the base of the soup.
• Onion: Adds sweetness and depth to the asparagus broth.
• Dry white wine: Enhances aroma and balances the earthy notes.
• Butter: Builds richness and helps develop a nutty base for the roux.
• All-purpose flour: Thickens the soup for a smooth, creamy texture.
• Egg yolks: Lend silkiness and a custard-like mouthfeel.
• Fresh lemon juice: Adds bright acidity that defines the soup’s character.
• Olive oil: Used for roasting vegetables, adding both flavor and sheen.
• Mushrooms: Contribute a roasted, umami-packed contrast.
• Salt and black pepper: Essential for seasoning balance.
• Fresh dill and oregano: Provide a herbaceous finish.
Ingredient Substitutions and Variations
• Vegetarian alternative: Use vegetable broth instead of asparagus trimmings for a quicker base.
• Dairy-free option: Substitute butter with olive oil and skip egg yolks for a lighter version.
• Wine-free adaptation: Replace wine with a splash of apple cider vinegar or extra lemon juice.
• Extra greens: Spinach or peas can be blended in for a deeper color and added nutrients.
• Mushroom variations: Cremini or shiitake mushrooms add a stronger earthy flavor if desired.
How to Make Lemony Roasted Asparagus Soup
- Prepare the asparagus broth: Peel and trim asparagus, reserving trimmings. Combine trimmings, onion, wine, and water in a saucepan. Simmer gently until soft, about 1 hour. Blend until smooth, then strain for a clear, flavorful broth.
- Make the roux: In a clean pan, melt butter and whisk in flour until golden and fragrant. Gradually add the asparagus broth, whisking constantly to create a smooth soup base.
- Temper the egg yolks: In a separate bowl, whisk egg yolks with lemon juice. Slowly incorporate a ladle of hot broth into the yolks to prevent curdling. Then return the mixture to the saucepan, whisking continuously until the soup thickens slightly.
- Roast the asparagus: Toss sliced asparagus stalks with olive oil, salt, and pepper. Roast at 450°F for about 8 minutes until golden yet crisp-tender.
- Sauté the mushrooms: In a skillet, heat olive oil and cook mushrooms until golden and crisp on the edges, about 8 minutes.
- Assemble and serve: Place roasted asparagus in bowls, ladle the lemony soup over, and top with crispy mushrooms. Garnish with dill and oregano for a fresh, aromatic finish.
Expert Tips for Perfect Results
• Don’t skip the straining step — it ensures a silky, restaurant-quality texture.
• Use fresh lemon juice, not bottled, for the best flavor and aroma.
• Roast vegetables separately to preserve their texture and color.
• Adjust consistency by adding a splash of water or broth if the soup thickens too much.
• Season at the end — acidity can shift flavors, so taste just before serving.
Serving Ideas and Flavor Pairings
Pair your Lemony Roasted Asparagus Soup with a warm crusty baguette, grilled cheese, or a light green salad. For a more filling meal, serve alongside roasted chicken or a Mediterranean-style grain bowl.
Garnish options include a drizzle of olive oil, shaved Parmesan, or a sprinkle of chili flakes for a mild kick. The soup can also be served chilled as a refreshing summer starter.
Storing and Make-Ahead Tips
This soup keeps beautifully in the refrigerator for up to three days. The asparagus broth can be prepared and stored separately for two days before assembling. Reheat gently over low heat to preserve the creamy texture — avoid boiling once the egg yolks are added. It also freezes well before the yolks are mixed in; just thaw and finish fresh when ready to serve.
