Step-by-Step Instructions for Lemony Roasted Asparagus Soup
- Prepare the Asparagus Broth: Peel and trim the asparagus. Slice the stalks diagonally into 1/4-inch pieces. Reserve the stems and peelings. Combine the asparagus trimmings, onion, dry white wine, and 6 cups of water in a saucepan. Bring to a boil, then simmer on low heat for about 1 hour. Once softened, blend the contents of the pan until smooth. Strain through a fine sieve and discard the solids.
- Make the Soup Base: In the same saucepan, melt the butter over moderate heat. Whisk in the flour and cook for about 3 minutes, until golden and nutty. Gradually whisk in the strained asparagus broth, and bring to a gentle simmer. In a separate bowl, whisk the egg yolks with lemon juice. Slowly whisk in 1/4 cup of the hot broth, then whisk in half of the remaining broth. Return this mixture to the saucepan, and simmer while whisking frequently until hot. Season with kosher salt.
- Roast the Asparagus: Preheat your oven to 450°F. On a rimmed baking sheet, toss the sliced asparagus with 2 tablespoons of olive oil, and season with salt and pepper. Roast for about 8 minutes, stirring once, until the asparagus is golden and slightly tender but still firm.
- Prepare the Mushrooms: Heat the remaining 3 tablespoons of olive oil in a nonstick skillet. Add the oyster mushrooms and cook over moderate-high heat for about 8 minutes, until golden and crispy.
- Serve the Soup: Place the roasted asparagus in shallow bowls, ladle the hot soup over it, and top with the crispy oyster mushrooms. Garnish with freshly chopped dill and a sprinkle of dried oregano before serving.
Tips & Tricks for the Perfect Lemony Roasted Asparagus Soup
- Avoid Overcooking the Asparagus: When roasting, make sure to keep an eye on the asparagus so that it retains its texture and doesn’t become too soft. You want it slightly firm with a light char.
- Whisk the Egg Yolks Slowly: To prevent the eggs from curdling, gradually add the hot broth to the egg yolks while whisking constantly.
- Season the Soup Well: Adjust the salt and pepper to taste. The soup should have a balanced tang from the lemon and a creamy, smooth consistency from the broth.
Pairing Ideas and Variations
This Lemony Roasted Asparagus Soup pairs wonderfully with a variety of dishes. For a light lunch, serve it alongside a fresh, leafy green salad or some crusty bread for dipping. You can also try a grilled cheese sandwich for a cozy meal.
If you’re looking for variations, here are a few suggestions:
- Spicy Version: Add a pinch of red pepper flakes or a dash of hot sauce to the soup for an extra kick.
- Vegan Version: Swap the egg yolks for a plant-based cream or cashew cream to create a dairy-free soup.
- Lighter Version: For a lighter, broth-based option, skip the flour and egg yolks and focus on the roasted vegetables and broth.
