Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• Butter (for sautéing aromatics)

• Onion, diced

• Garlic, minced

• Asparagus spears

• Vegetable or chicken broth

• Salt

• Pepper

• Lemon juice, freshly squeezed

• Parmesan cheese, freshly grated

• Asparagus tips (reserved for garnish)

Directions

1. In a large pot, melt the butter over medium heat. Add the diced onion and minced garlic and cook until soft and translucent (about 8 minutes).

2. Meanwhile, prepare the asparagus: trim off the tips (reserve them for garnish) and chop the remaining spears into ½‑inch pieces.

3. Add the chopped asparagus, broth, salt, and pepper to the pot. Bring to a boil.

4. Reduce heat, cover, and simmer until vegetables are very tender (about 30 minutes).

5. Use an immersion blender to purée the soup until smooth. (Or carefully work in batches in a blender.)

6. Return the puréed soup to the pot. Stir in the fresh lemon juice and grated Parmesan until well incorporated.

7. In a separate small pot, cook the reserved asparagus tips in salted boiling water until they are tender‑crisp.

8. (Optional) Shock the tips in an ice bath or rinse under cold water to preserve their bright green color.

9. Ladle soup into bowls. Top each serving with asparagus tips, extra Parmesan, fresh herbs (if desired), and freshly ground black pepper.

Servings and timing

• Servings: about 4 to 6 bowls

• Active time: ~15 minutes prep + sautéing + assembling

• Simmer time: ~30 minutes

• Total time: ~45 minutes

If you prefer a quicker version, you can shorten the simmering time slightly if your asparagus is very tender, though texture might be less silky.

Variations

• Substitute half the broth with milk (dairy or non‑dairy) for a creamier version

• Use vegetable broth to make it fully vegetarian/vegan (omit Parmesan or use vegan alternative)

• Add fresh herbs (thyme, chives, tarragon) for extra flavor

• Stir in a dollop of crème fraîche or Greek yogurt just before serving

• Garnish with croutons, toasted nuts or seeds for added texture

Storage / Reheating

• Storage: Cool the soup to room temperature, then store in an airtight container in the refrigerator for up to 3–4 days.

• Freezing: Freeze in freezer-safe containers (leave some headroom). Note: the reserved asparagus tips are best omitted when freezing; you can add fresh asparagus or reheat and blend them in later.

• Reheating: Gently warm on the stovetop over low to medium heat, stirring occasionally. If the soup is too thick, you can thin with a splash of broth or water. Reheat only until hot—not boiling—to help preserve flavor and texture.

FAQs

What asparagus should I use — thick or thin?

You can use either. Thicker asparagus offers more substance and green flavor, but thinner spears cook more quickly. Just adjust your chopping and simmering accordingly.

Can I skip sautéing the onion and garlic?

Technically yes, but sautéing builds depth of flavor. If you skip it, the soup will be more one‑dimensional.

Can I make this soup in a blender from the start?

Yes — after cooking the asparagus and aromatics in a pot with broth, you can transfer in batches to a blender. But be careful with hot liquid (vent the lid). An immersion blender is safer for hot soups.

Do I have to cook the asparagus tips separately?

No, but cooking them separately preserves their shape and bright color as a garnish. If you skip that, you can simply purée them with the rest and forgo the garnish.

How can I make it vegan?

Use vegetable broth and omit the Parmesan (or substitute a vegan Parmesan). You might want to add extra salt or nutritional yeast to boost savory flavor.

What if the soup is too thick?

Just thin it with a little extra broth, water, or milk (dairy or plant‑based) until you reach your desired consistency.

Can I add cream or milk to make it richer?

Yes — stirring in a little cream, half‑and‑half, or milk (or non‑dairy milk) at the end will make it richer. Add gradually and taste as you go.

Is blanching the asparagus tips necessary?

It’s not strictly necessary, but gives you crisp, bright green garnish that looks and tastes better than mushy tips.

Will reheating cause separation or graininess?

It can, especially if you use dairy. That’s why reheating gently is important. Stirring continuously helps. If separation happens, a quick re‑blend helps bring it back together.

Can I freeze the soup after blending?

Yes, you can freeze the puréed soup (without tip garnishes) in suitable containers. Thaw overnight in the fridge and rewarm gently.

Conclusion

This asparagus soup with lemon and Parmesan is deceptively simple yet elegant. With just a handful of ingredients, you’ll get a smooth, bright, flavorful soup perfect for spring—and easily adaptable for different diets or preferences. Try it as is, or tweak with your own touches, and enjoy each creamy, green spoonful.
