Choosing the Right Asparagus

Fresh vs. Frozen Asparagus

Fresh asparagus delivers the brightest flavor for this soup, but frozen can work in a pinch. Look for vibrant green stalks with tightly closed tips and minimal flowering. Avoid bunches with woody, dried-out ends or limp stalks.

Thickness Matters

Medium-thickness asparagus spears work best for this soup. Pencil-thin spears can overcook quickly and lose their distinct flavor, while extra-thick stalks may require longer cooking time.

Seasonal Selection

Spring asparagus (March to June in most regions) offers the sweetest flavor and often costs less during peak season. When buying, check that the cut ends aren’t dried out or excessively fibrous.

Ingredients & Prep

Serving Suggestions

If you’re hosting a dinner party, present the soup in small cups as an elegant appetizer with a few asparagus tips and a drizzle of quality olive oil on top.

FAQs

Can I use the woody ends of asparagus in this soup?

While traditionally discarded, you can actually simmer the woody ends in your vegetable broth for 20 minutes, then strain them out before using the broth in your soup. This adds extra asparagus flavor without the fibrous texture.

How do I fix a soup that’s too thin?

If your soup turns out thinner than desired, simmer uncovered for 5-10 minutes to reduce, or blend in 1/4 cup of white beans for instant thickness without changing the flavor profile.

Is this recipe suitable for meal prep?

Absolutely! This vegan asparagus soup freezes exceptionally well. Portion into individual containers for grab-and-go lunches or quick dinners throughout the week.
