Creamy Lemon Pasta with Green and White Asparagus
A Danish spring pasta celebrating tender asparagus in two varieties, bound with a silky lemon-egg sauce that's both light and luxurious. Thick white asparagus brings delicate sweetness while thin green spears add grassy brightness; spring onions contribute subtle allium notes. The sauce—a warm emulsion of egg yolks, cream, and fresh lemon—clings gently to the pasta without heaviness. This dish suits home cooks seeking restaurant-quality simplicity and those craving vegetable-forward meals that feel special. Serve it at spring dinners or light lunches when asparagus peaks. This version avoids heavy cream by using the asparagus cooking liquid to stretch the sauce, creating a refined, bright finish that lets the vegetable flavors sing rather than mask them.
Ingredients
Instructions

Cut all vegetables into ⅓" pieces.
- 4
Bring water and vegetable stock cube to a boil, add the vegetables, return quickly to a boil, then remove from heat and cover; let rest 5 minutes.
- 5
Transfer vegetables to a plate, cover with a cloth to keep warm; reserve the cooking liquid in the pot.
- 6
Whisk together egg yolks, flour, cream, lemon juice, lemon zest, salt, and pepper.

Slowly whisk the egg mixture into the warm vegetable cooking liquid over medium heat, stirring constantly until the sauce thickens.

Tips
Whisk the egg mixture into warm—not hot—cooking liquid to prevent scrambling; add it slowly while stirring constantly for a silky emulsion.
Cut vegetables uniformly into 1 cm pieces so they cook evenly; white asparagus requires slightly longer blanching than green, but both benefit from the gentle carryover cooking under the cover.
Reserve the vegetable cooking liquid before draining; its starch and mineral content enriches the lemon sauce and reduces the need for extra cream.
Good to Know
Refrigerate finished dish up to 1 day; sauce may separate slightly upon reheating. Reheat gently over low heat with a splash of water.
Prepare and blanch vegetables up to 4 hours ahead; refrigerate separately. Cook pasta and make sauce just before serving for best texture and emulsion stability.
Serve immediately in warm deep bowls with crusty bread and a crisp white wine such as Sauvignon Blanc or Chablis.
Common Mistakes
Whisk eggs into boiling liquid to avoid scrambling; add slowly over medium heat with constant stirring.
Don't overcook vegetables; 5 minutes resting under cover is sufficient to keep them tender and warm.
Stir sauce constantly to prevent lumping and ensure even thickening.

FAQ
Can I make this sauce ahead?
The sauce is best made fresh just before serving, as the emulsion is delicate and may separate when reheated. Prepare all other components ahead and combine at the last moment for optimal texture and flavor.
What if I don't have fresh tarragon?
Fresh parsley, dill, or chives work well; use the same quantity. Tarragon's subtle anise notes are traditional, but these alternatives add different herbaceous notes that still complement the lemon and asparagus beautifully.
Can I freeze this pasta?
Freezing is not recommended due to the delicate egg-cream sauce, which may separate and curdle upon thawing. The asparagus texture also deteriorates. Store leftovers refrigerated up to 1 day and reheat gently.
