Creamy vegan asparagus soup with red lentils is a hearty and healthy, protein rich soup to enjoy while fresh asparagus is in season. With minimal ingredients, this easy asparagus soup low-fat, well-balanced and ready in about 30 minutes!
I’m absolutely loving the season’s asparagus this year! It’s delicious anyway you cook it. Asparagus soup was one of my all time favorite soups growing up as a child. It’s a pleasure to make from scratch and not eat it from a can like I did so many years ago.
The recipe is super easy to pull together and much more flavorful than any canned asparagus soup. I highly recommend making it at least once while fresh asparagus is in season.
I’ve also included red lentils in this recipe to round out the nutritional profile and adding heartiness. Finishing off the soup with a little lemon juice will add brightness to the overall dish. It’s all so simple and good!
And don’t let the short list of ingredients fool you. You can be sure this soup will be filling and satisfying!
Creamy Vegan Asparagus Soup + Red Lentils
What you’ll need:
- Asparagus
- Leeks
- Red Lentils
- Tarragon
- Lemon
- & Salt, pepper and a little oil
A Word About Red Lentils
The lentils will add density to the soup making it thick, creamy and add a good dose of protein. I’ve used red lentils in a few other soup recipes like this Creamy Broccoli + Red Lentil Soup and this Butternut Squash + Red Lentil Soup.
I love using them in pureed soups. They have a mild flavor and soften up quickly. I also love the fact that they cook up very light in color as to not change the overall color of the dish too much.
Pureeing other lentils here would result in a muddy colored soup, not very pleasing to the eye so I don’t recommend them. Red lentils are my favorite for pureed soups!
A Note On Leeks
Leeks are another favorite of mine and I use them whenever I can. Compared to onions, they have a more delicate, sweeter flavor that I love. If you can’t find them or don’t care to use them, 1 medium sized white onion will do just fine.
Tip: When using leeks, be sure to rinse them well under cool running water to help remove any sand or dirt that has collected between the stalk slices. Once trimmed and cleaned, slice thinly and you’re ready to cook.
How To Make Asparagus Soup with Red Lentils
- Prep veggies: Trim both ends off the leeks, we’ll be using the white and light green parts only. Make a slit down the center lengthwise and run under cool water to remove any debris/dirt that may have collected between the layers. Lay on flat surface, thinly slice widthwise. Here is a great guide to prepping leeks. Trim asparagus ends and discard. Cut remaining asparagus into 1 inch pieces.
- Cook: In a large pot or dutch oven, heat oil over medium heat. Add leeks and saute for about 5 minutes, or until softened. Add in tarragon, lentils, asparagus, vegetable broth and salt & pepper. Bring to a boil, cover, reduce heat and simmer for 15 – 20 minutes. Let cool a bit.
- Puree: Using an immersion blender, puree soup until desired consistency (I left mine a little chunky). You can also puree using a blender or food processor (this method will most likely require you to puree in 2 batches). Once pureed, add back to the stove and add juice of 1 lemon, give a good stir. Add more water as needed to thin, no more than 1 cup should be needed. Taste for seasoning and heat on low as needed to warm.
- Croutons: While the soup is cooking or cooling, cube two slices of your favorite bread (I used the end pieces). Place cubes on a small baking sheet and drizzle with olive oil, add a pinch of salt and toss well to coat. Toast in a toaster oven as if toasting bread (this was my method using the small tray that came with the toaster oven). Alternately, use the broiler in your oven and set it at medium, place baking sheet under broiler for 5 – 7 minutes, tossing once or twice, until bread is toasted and slightly golden. Simple and easy croutons!
Serve soup in individual bowls topped with croutons and fresh cracked pepper.
How Long Will Leftovers Keep?
Leftovers will keep for 5 – 6 days in the refrigerator, stored in a covered container. Simply re-warm on the stovetop or the microwave. It makes a great meal prep for the week with homemade no knead bread or Naan on the side for soaking up the juices.
Can You Freeze Asparagus Soup?
Yes, it freezes well for up to 2 months! My favorite way to freeze asparagus soup is in individual small containers that are freezer safe. That way whenever I want to cozy up with a bowl of warm, nourishing soup I can just pull it from the freezer and warm it up. You can also freeze larger portions in large ziplock bags or containers.

Feel free to change up the herbs. A few good replacements for the tarragon would be dill or thyme.
