Who Knew An Asparagus Soup Recipe Made From Asparagus Trash Could Be So Delicious!

While garlic soup is a traditional recipe found in many cuisines, it is most known for its medicinal properties to ward off sickness. However, in this asparagus ends soup, it is the rich deep flavor of garlic that gives balance and a lingering taste to this soup, not simply a light hearted vegetable soup.
Ingredients Needed For Asparagus End Soup
- Asparagus ends – you know, those woody ends you usually cut off and toss away, simply peel and use those in this luscious soup.
- Garlic – either fresh raw garlic, with its hint of heat, or roasted garlic with its slightly nutty flavor.
- Vegetable stock or water – a vegetable broth, or other favored stock is used, however the flavors in this soup stand on their own, so perhaps just hot water is enough for you.
- Olive oil – olive oil in keeping with a plant based oil adds richness.
- Fresh herbs – basil is perfect for the flavors in this soup, though fresh marjoram adds a little more intensity to the flavor.
- Salt – to your taste, either a kosher coarse salt or a slightly smoky salt for another layer of flavor.
- White wine – brings the acidity and brightness to the broth, though a squeeze of lime juice can be used instead.
- Mascarpone or creme fraiche – just a dollop on top the soup when served adds a creamy finish. A delicious dollop of Almond cheese, in keeping with a completely plant based, is also an option.
Tools You Will Need for this Spring Soup
- Medium soup pot with a lid
- Chinois set or fine sieve strainer with a wooden spoon, either will work however a chinois is a wonderful tool in the kitchen as it crushes all the bits against the holes, forcing every bit of liquid out for use.
- Food processor or Blender to liquify all the chunks, making it easier to press through a strainer.
- Measuring tools which you probably already have.
How to Make Asparagus Ends Soup
Step 1: Simmer the Asparagus – Bring water or stock to a low boil. Add asparagus ends, cover, and simmer for 30 minutes. Let cool slightly.
Step 2: Blend – Transfer the softened asparagus to a blender or food processor and puree until smooth.
Step 3: Strain – Press the puree through a fine mesh strainer into the reserved broth, extracting all the flavor while removing fibrous bits.
Step 4: Build Flavor – Return to heat. Add garlic, basil, olive oil or butter, white wine, and salt. Simmer gently to combine flavors.
Step 5: Serve – Ladle into bowls and top with a dollop of mascarpone and fresh basil.
A Food Waste Resolution
Some of my most favorite things created in my kitchen have come from scraps, bones and things I probably threw away when I was a young cook, and knew no better.Â
The best way to create a vegetable soup is to start the cooking process with scraps, and just boil the heck out of them until their flavors remain in the pot and not the trash or compost pile.
That was how this scrumptious, nutritious asparagus stock became the base for a light evening meal, served simply with crusty bread.
Tips for the Best Asparagus Soup
- Strain well for a silky texture

Frequently Asked Questions
Can you really use asparagus ends for soup?
Yes! While they are too tough to eat whole, they release a lot of flavor when simmered and blended.

Straining removes the fibrous texture, leaving a smooth, velvety soup.
Can I skip the cream?
Yes, the soup will still be flavorful, just lighter.
Is this soup healthy?
Yes, it’s made from whole ingredients and can be very light depending on how much cream you use.
Tips To Snap – Not Cut – Asparagus Ends
Sure, it would be easy to chop off the ends of many stalks of asparagus, but are we really sure where the woody end stops and the tender top begins?
Nature makes it easy for us to know, with a little wiggle of the asparagus spear near the bottom, it easily snaps at the perfect spot we are looking for.
In this way, we waste none of the tender parts for other recipes, and make great use of the woody ends we might otherwise toss in the trash.
Dirt To Dish – More Plant Based Recipes
Such a refined soup, you will wonder why you ever threw the end pieces away. It’s beautiful garden grown veggies, like these asparagus, that inspired my book Dirt to Dish.
Once I learned how easy it is to grow everyday vegetables in pots on my deck or a designated section of my garden, I became hooked on growing whatever I could to cook with.
More Spring Soups to Try
Many great soups start with a good homemade stock, whether from vegetable scraps, from seafood bones or shell, beef, chicken or lamb bones for a great bone broth based consume.
However, legumes for a thick textured soup base or classic cold soups simply made with vegetables, make fantastic soups. Here a few of my favorites:
- Cold Greek Cucumber Soup – a refreshing cold soup with all the flavors of a Tzatziki with cooling and nutritious cucumbers, mint or dill and yogurt.
- Black or White Bean Soups – with or without meat, makes for a complete meal, high in protein and rich in flavor.
- Ginger Carrot Red Lentil Soup – loaded with nutrients and perfect for meatless meals, with the spice of ginger, carrots, red lentils and lots of spices to make you forget there is no meat.
