broccoli stalk soup recipe

Print Friendly

This month I’ve been teaching a broccoli and cauliflower stir-fry in my classes.  I am using only the florets since I know the stalks aren’t as popular in my house.  It’s all very well and good, except for the fact that I’ve been left at the end of each week with a heck of a lot of broccoli stalks.  I’m sure you’ve gathered by now that I am a compulsive use-everything-you’ve-got kind of a cook.  I absolutely hate to waste food!  In fact, I started a tradition in the house called “Frittata Fridays.”  That’s when I pull together bits of leftovers and random vegetables and turn them into breakfast.  Everyone’s happy!

So in order to not throw away the perfectly good broccoli stalks, I have been juicing lots of them into our juices.  But there’s only so much of that I can take.  What else could I use them for?   On a whim I decided to see if I could turn the stalks in a pureed soup like my Cauliflower and Roasted Garlic Soup, which is one of my absolute favorites.  My biggest concern was that the stalks wouldn’t have enough flavor and the soup would taste like nothing — WRONG!  It was delicious.  Warm, rich, creamy and using one of my favorite soup-thickening techniques (cooking and pureeing Yukon Gold potatoes with the soup), it tasted like there was lots of cream or butter when there was none.

Nutritionally speaking, the stalks are quite comparable to the florets, which is awesome since broccoli is once of those super foods you should be eating a lot of (and not throwing into the garbage!)  In fact, I’m big on the whole cruciferous family of vegetables which includes all the cabbages, kale, bok choy, cauliflower, brussels sprouts, collard greens and more.  These vegetables contain incredible amounts of vitamins, minerals, antioxidants, cancer-fighting compounds, and even protein.  Load up, people!

I enjoyed this soup straight away with an extra pinch of flaky sea salt and a few grinds of black pepper.  My husband stirred into his bowl a big pinch of shredded raw cheddar cheese and thought that was great.  For the girls, I made them grilled raw cheddar cheese and kale pesto sandwiches on spelt bread and they loved dipping those into the soup.  Even Mr. Picky finished his entire bowl — plain of course, with absolutely nothing added.  This was a winner all around!

    Made today with broccoli stalks from end of season garden bed clean out. So good, so easy and all ingredients were already in my pantry. Thank you!!

  2. Jyl says

    This was delicious!! I loved it. I always want to eat more veggies – and am just not a fan of the veggie smoothies…but this was perfect! I thoroughly enjoyed it. Thanks!!!

    • Pamela says

      Thanks! And thanks for reminding me about this soup — I might have to make it this weekend. Such a favorite here!

  3. Ashley says

    Hi, Pamela!

    I am looking forward to trying your recipe, but about how many cups of broccoli stalks are in 2.25-2.5lbs?

    Thank you!

  4. Angie says

    The soup was delicious. I had some for lunch over several days adding little bits of things like tiny cubes of ham one day, grated cheese another day and croutons and sometimes just nothing else but this delicious soup. Thanks for sharing this recipe.

  5. iris says

    Thanks a million for this recipe, it was so delicious! I’m a virgin vegan so I followed your recipe to the T. And glad I did my husband and sons loved it as well. Do you have a recipe book? I would purchase a copy.

    I usually use the stalks in recipes with broccoli peeling them and slicing into coins. They cook at the same time as the florets if steaming, and are wonderful in stir fries.
    Today, not using the stalks and not wanting to thrown them out, I flung them into my food processer and ran to my laptop to look up broccoli stalk soup. There you were! The soup is on my stove now.

  7. Valerie Ruisseau says

    Thank you for this recipe! I absolutely looooove broccoli and I always felt like crying when throwing away the stalks, I will definitely not do that again. I have just prepared this soup and I’m amazed by its taste! By the way, next in line is your cauliflower and roasted garlic soup 😉 I love cooking and I have just learned today the roeasted garlics lesson. Can’t wait to try!

    Hi, as I am helping an organic gardiner, I have broccoli stalks by the tens and after freezing the florets decided to try soup with the stems. After grinding then up, adding some regular milk, sweet curry and salt, I had a tasty soup. Now I’m going to try the onion, garlic and potato and perhaps some of my frozen chicken stock. I did try a batch with the florets but it had a mushy texture. Thanks.

  9. Donna says

    perfect for the stalks sitting in my fridge after freezing the florets for winter. Have you ever frozen the finished soup?

    • Pamela says

      I haven’t frozen it, but I can’t imagine why you couldn’t. Although not sure how well it would freeze if you are starting with defrosted broccoli….

    I googled recipes for broccoli stalks and stumbled upon this one and gave It a try. I made a HUGE pot with added broccoli florets and ate the entire thing all week. It was delicious!! Thanks for the recipe!

    • Pamela says

      Awesome. I love being efficient with food, and I especially love when the recipe taste fabulous. So glad you enjoyed this too!

  11. Edward Maddox says

    I too can not throw away the stems of broccoli. I bag them and put them in the freezer. When I have time, I plan to puree them and make some sort of soup. So today I had some time and brought them out and let them thaw. Pureed with 2 cups of water and about filling the blender, I pored the puree into a sauce pan and brought to a simmer, keeping it there for about 20 minutes to cook the broccoli.

    Then I went to my computer and looked for “broccoli stalk soup” and found you. I am underway to add some seasonings and some sharp cheddar cheese. Looking forward to the result.

  12. Michelle AP says

    Exactly what I was looking for! Can’t wait to make this later today. Happy Google pointed me to you. Will be checking out more of your recipes. Looks like you are a real food fan like me:)

  13. Rob says

    Brilliant! I was looking for what to do with left over stalks and green onion tops and I stumbled upon your delicious recipe. I ditched the potato and added miso paste (red, I live in tokyo). I was cutting up a salad and added the bottoms of 2 romaine lettuce heads. It all got boiled and blendtec’d and “garbage soup” was born! When it is fresh veggie shoping day, this soup gets made. And to think, I used to just chuck it all! Cheers!

  14. says

    Brilliant… Just what I was looking for… as I am making some of this soup tomorrow.. And will be following your recipe .. Many Thanks
    Blessings to you and yours :-)

    I’m simmering “broccoli stalk soup” at this very moment. My goal is two-fold: use the stalks plus fill my tummy when I need a low calorie yet satisfying meal.

  16. Louisa says

    I tried freezing the stalks because I too thought I would freeze until i had enough. They did not thaw well. They were water logged for some reason. I don’t know if it was me or the broccoli but it didn’t work so well! But the soup with the fresh stalks was fantastic!!!

  17. Jodi Miller says

    I made the soup last night for dinner. Everyone LOVED it! In fact, my daughter ate it for breakfast this morning.

  18. says

    Love this! I have 4 heads of broccoli in my fridge for recipes right now and this is a swell solution to the plethora of leftover stalks (though my dogs do like them too!).

    • Pamela says

      No way. Your dogs eat broccoli? That’s amazing. You know what I’m thinking? I bet you could also peel and freeze the stalks and then make the soup when you’ve accumulated enough. I’m going to give that a try since I don’t think I can make this soup again for a while ;).

  19. Janet Anderson says

    Cook’s Illustrated has a technique for roasting broccoli, including the stalks, at high heat. My family, including both boys, fight over the stalk pieces when I prepare broccoli this way. They are delicious! This sounds great, too!

    • Pamela says

      Thanks for the suggestion, Janet. I must try that since I have tons of stalks again and my family is starting to get tired of this soup!

    • Karen says

      I’ll bet some roasted bits would be delicious incorporated into the soup prior to serving, then topped with cheddar cheese and bacon crumbles. I’m going to try that tonight!
