Do you love soup season as much as I do!?

A dietitian friend of mine shared this clean and comforting veggie soup recipe with me last year. If you’ve been over-indulging or stress eating during quarantine, this soup is the perfect way to help you get back on track!

Cashew cream (cashews pureed with water) is blended with immune-boosting broccoli, lentils, cashews, onions, carrots, celery and spinach. This results in the healthiest and most delicious and creamy soup ever! It’s also vegan and gluten-free.

Drizzle a bowl with a bit of olive oil and serve with a big green salad or a piece of whole grain bread. Trust me, you feel so nourished and wholesome, you’ll be inspired to make other good-for-you lifestyle changes too!

  1. This soup is so flavorful and has such a nice texture! I made my boyfriend try a spoonful and he asked if there was enough for him to have a whole bowl because he liked it so much. It makes a ton so I halfed the recipe. I also used red lentils instead of green bc it’s what I had.

    Really good! I did make changes for my taste and yes I hate when people give a recipe 5 stars but then change it up. Lol.  I don’t love lentils so I used white beans.  I also added garlic.  I did use 4 cups of chicken broth and 3 cups water and then sprinkled it with some extra seasoning so my family would be more likely to eat it.  I then changed its name it Veggie Bisque, again to keep my family from running.  Everyone loved it, including the kids.  

    1. I forgot to say I also used an immersion blender which made it really easy and I didn’t let it cool because I was in a hurry. It worked just fine.  

  4. This recipe is SO GOOD! Followed the recipe exactly, and it delicious and perfect. Thank you for giving my family another outstanding thing to eat! 🙂

  5. Make sure you add 2 tbsp Better Than Bouillon chicken stock concentrate.
    It definitely wouldn’t be salty or flavorful enough without it.
    With the simple addition, it is definitely 5 stars.
    I thought it was really good!
    Really liked it!
    Also, I soaked the cashews in 1 cup of boiling water before I blended in a Magic Bullet blender. The cashew creme was a perfectly smooth consistency this way.

  6. What can be substituted for nut allergies in this soup? Would coconut milk work ot perhaps white navy beans pureed in water instead?

  7. At first I thought there was no way a “detox” soup would be any good (made it for a January re-set one year) and realized very quickly I was wrong about this one. I love this soup and I crave it even when I’m not trying to “detox”.

    I’ve started adding in soft boiled eggs as a topping for additional protein as well as red chili flakes and additional pepper on top.

    Side note, I’ve always made this recipe as written and I always have WAY more than 5 servings (which is not a bad thing).

  8. Based on the high rating, I feel like I missed an ingredient or a step. I checked several times, and I did not. There just was not enough flavor for me. I’ve been adding sriracha and brown mustard to spice it up. Otherwise, very filling for a soup!

  9. Love this recipe! I found that when adding the spinach to the soup when warm, it wilts and the immersion blender can’t blend the spinach well – rather it just wraps around the blades. Next time I made it, I used a nutribullet to make my cashew cream (used dry roasted unsalted cashews and no issues with grittiness) and just blended the raw spinach into the cashew cream in the nutribullet before pouring in the soup – works wonders and helps a ton with the blending process! I also add a little more salt and spices to my taste, but the foundation of the soup is great.

  10. I love this soup.  I made it last week and I’m making it again.  It’s delicious and healthy.  I didn’t have trouble with the cashews at all.  I did not soak them.  Instead I blended them  for one minute on “chop”, one more minute on “blend” and a final minute on “purée”.  Your blender might have different settings but just try blending the cashews and water for a total of three minutes.  

  11. Shortly after the water started boiling in Step 1 my entire kitchen smelled so great. This recipe did not disappoint, I really like that the soup is water based and is not using stock as the base, this gives the soup a very clean and light taste. 

    The only change I made to the recipe was to salt the lentils as they cooked and to add course sea salt to the top of the soup after I ladled in a bowl and drizzled with olive oil.

    I’m looking forward to having again for lunch tomorrow.

    Super recipe!

  12. This was such a flavorful soup that will definitely be on rotation for fall/winter. I made a few substitutions based on previous reviews….I used low sodium chicken broth in place of the water, added minced garlic, and soaked my cashews overnight. It tasted like an indulgent comfort food soup minus the guilt with a ton of great nutrients.
