A Spargelzeit Soup Recipe
This 'sparkling' Spargelsuppe is the creamiest white asparagus soup you ever had! I used a mixture of fresh and jarred white asparagus to create it (to save money) and it was just foamy, creamy, yet light and so delicious! I add whipped cream (plain and unsweetened) and egg yolk, which is my secret weapon to creating a cloud-like soup experience. The hint of lemon and the nutmeg make this white asparagus soup come together. The kids even went crazy for it.

Get Your White Asparagus Now or Never
Right now is the very end of white asparagus season, so you don't want to wait around for too long or it will be gone! I have never been able to find German white asparagus in the United States, being able to buy the 'white gold' at all has been a luxury! Usually, white asparagus in America is shipped in from Peru. But recently I found some Dutch Spargel at our local German restaurant in Kansas City, Affäre. But Sophie, you paid 60 dollars for two pounds of Spargel? Yes, I did and it was still cheaper than a plane ticket to Germany. And it brings back all the best memories as if I made a mini trip back home. Spargel is worth the extra money (the Peru-grown kind you can find at Whole Foods usually runs around 8 dollars a pound) as it's so delicate and tasty!
What Makes White Asparagus White?
Ever wondered what makes white asparagus white? I wondered the same thing. While I grew up with the white asparagus season coming and going, nobody ever taught me the difference between white asparagus and its green counterpart. The only difference lies in the asparagus being covered with lots of mulch and dark plastic as it grows, allowing for no sunlight to reach it, and thus no photosynthesis to take place. It’s the albino version of its green brother and tastes more delicate, mild, and less bitter. One of the other differences is that it is a lot more labor-intensive, from the farming methods to the food prep methods. It requires peeling of wood-like skin of each spear before cooking. But if you haven't had it before, believe me, it’s worth it!
A Sparkling White Asparagus Soup
The Austrian sparkling wine I added to this soup works beautifully in tying in all the flavors of the asparagus, cream, lemon juice, and spices. Schlumberger’s Brut Classic sparkling wine is prepared using the traditional Champagne method, and it’s bright, fruity aromas are perfect in the soup as well as poured in flutes to be enjoyed with the soup. And who doesn’t love a bubbly companion? Make sure to check out Marussia's website to find out availability at stores near you.
- White asparagus. I know this one can be tricky to find fresh. If you're having trouble, use jarred white asparagus for the whole recipe. I used about half fresh and half jarred to save on costs.
- Vegetable broth. I buy organic vegetable broth or you can make broth yourself by simply cooking vegetable peelings and end cuts in water for 30ish minutes. I save vegetable peelings in a large freezer bag whenever I remember to do so.
- Butter. The real kind. I like to buy Kerrygold or the New Zealand grass-fed butter that Costco sells and use it for baking as well.
- Sugar and you'll need just a pinch of it to cook the asparagus. This helps get rid of any remaining bitter notes.
- Flour or cornstarch to thicken the sauce.
- White sparkling wine. The bubbles help elevate this soup and help make it light and perfect. I used Schlumberger’s Brut Classic.
- Egg yolk for thickness and flavor.
- Heavy whipping cream. And quite a bit of it. Nobody said this was a diet soup. You'll whip up half of the cream, making this soup feel like spooning clouds.
- Salt, pepper, and nutmeg. The only seasonings that are needed for this soup.
- Lemon juice. Buy a fresh lemon and squeeze it. It definitely makes a difference in flavor.
