Apple Celery Smoothie, a Low Sugar Recipe

Refreshing apple celery smoothie recipe that’s packed with fiber, vitamin C and phytonutrients to heal your body from the inside out.

Low sugar apple smoothie recipe

I’d like to share an apple celery smoothie recipe that’s surprisingly delicious. My favorite part of this smoothie is the fennel, a tasty herb that reminds me of black licorice. Yet, I also love that it’s low in sugar and insanely energizing as well.

My love for Good & Plenty candy led me down a plant powered path to find a great smoothie recipe with a black licorice flavor. This recipe checks all the boxes: fun new ingredients, fresh flavor, low in sugar, and refreshing to the core.

In fact, I love this recipe so much I’ve included in our new meal planner called Rawk the Year. Rawk the Year features over 400 recipes, weekly meal plans, personalized shopping lists, access to all of our cleanses and more. Try it free for 14 days and see what you think! Now…what was I going to say about celery? Ah, yes…

Celery Smoothie Health Benefits

I know this smoothie may get a bad rap to start, with celery in the title, yet hear me out. The celery juice fad wasn’t just for fun. Celery is loaded with health benefits, including:

  • Antioxidants– Celery has at least 12 different types of antioxidants in just 1 stalk.
  • Digestive Aid– This is a great veggie to eat daily as it has 5 grams of soluble fiber in 1 cup, which keeps things moving.
  • Helps reduce inflammation– The older I get, the more easily my body can succumb to inflammation. Celery helps fight this, making this celery smoothie a must on the menu when I’m training.
  • Alkalizing effects– The minerals in this veggie can help neutralize acidic foods we eat.
  • Full of vitamins and minerals– While celery is mostly water, it’s also got vitamins A, C, and K, along with potassium and folate.

Who knew this simple, whole food could be such a force for health and wellness?! I love knowing the benefits my body is getting from this celery smoothie recipe. Scientists have actually studied celery extract as an antibacterial and antimicrobial agent against treating MRSA (methicillin-resistant S. aureus) according to the National Library of Medicine.

Low Sugar Celery Smoothie Recipe

If you’ve ever gone on the hunt for a great low carb/low sugar green smoothie, look no further. A fruit or veggie is considered a low glycemic option (low in sugar) if 1 serving has a glycemic index score of less than 55. Check out the glycemic index of the ingredients in this celery smoothie recipe:

  • 1 cup spinach: less than 1
  • ¼ fennel bulb: 16
  • 1 celery stalk: 15
  • 1 green apple: 38

  • juice from 1 lemon: 20

My blood sugar’s doing a happy dance knowing this celery smoothie won’t raise it! This recipe can be a great afternoon pick-me-up, or even a refreshing evening treat to help stabilize the body’s blood sugar for the night.

  1. Melinda F Jackson says:

    I’d like to add the plant based protein to this smoothie and not include the fennel. I’ll try it tomorrow.

    • Simple Green Smoothies says:

      Truth be told, I wasn’t thinking I’d be a fennel fan either, Melinda. Yet I totally love it in smoothies. Might be worth the adventure! Let us know if you give it a blend!

  2. Deborah Norvell says:

    I did the 7 day smoothie challenge. All are very good but definitely high in sugar.

    So, thank you for this low carb recipe. I tried it without the fennel because I don’t like licorice and added a serving of your protein smoothie boost. It was good and sipped on it throughout the day.
    However, do you have a suggestion for replacing the fennel? If not, I’ll just leave it out.
    Thank you.

    • Simple Green Smoothies says:

      Love this question, Deborah! I hear ya about the fennel, as I wasn’t a fan at first either. However, we’d totally encourage you to give it a blend and see. It’s amazing how green smoothies have a way of disguising those ingredients that are so good for us, yet we wouldn’t eat otherwise. If fennel still isn’t your groove, then see if your blender can handle celery, caraway or anise seed as a substitute. The seeds will be strong in flavor, so go easy at first. Also, be sure to check out our Low Sugar Fruits for Smoothies! We think you’ll find it really helpful. Happy blending! 🙂

  3. Elle says:

    Hi, what is substitute for fennel ?

  4. Kathy says:

    Celery in a smoothie?! Man, you guys are always keepin it fresh at SGS! LOL. Can’t wait to try!

    • SGS Rawkstar Jess says:

      It’s so good! Def give it a try and let us know what you think!

  5. Kim says:

    Thank you for this low carb/ low sugar smoothie recipe. SO good!

  6. Dani says:

    Talk about a fiber party! This smoothie was THICK. I wasn’t sure i would like it so I added some more water and then tasted it. Pretty good!

  7. Amanda says:

    I love recipes that go big on greens – this is one of them! LOVE!

  8. Heather K says:

    Ok so this thirst quenching yummylicious smoothie takes longer than 5 minutes to prepare but it’s soooo worth it!! You didn’t specify if the celery, apple or ginger needed to be minced/chopped up but I did anyways. I literally could not stop drinking this smoothie, it was gone within 5 minutes! I definitely feel a burst of energy and serotonin kicking in. Thanks so much for the delicious recipe!!!

    • SGS Rawkstar Jess says:

      Hey Heather! So glad you loved this smoothie! It is sooo delicious. Depending on the type of blender you have, you really only have to cut your fruits + veggies into large chunks and your blender will do the rest. Keep on rawkin!

  9. Oli says:

    Hi! I’m not 100% sure how much a stalk of celery is. Is it just one “stick”.

    • SGS Rawkstar Jess says:

      Hey Oli! You are correct, it’s just one “stick.” The group of stalks (or sticks) is a bunch. You don’t need to put an entire bunch in! Happy blending! 🙂

  10. Angie Angelicchio says:

    Good morning,

    I would like if you can answer my questions.
    Can celery be frozen when in season? Does celery loose all or any nutritional benefits when frozen?
    Thank you very much.


    • SGS Rawkstar Jess says:

      Hey Angie! You can def freeze celery if you have a lot and don’t want it to go bad. In general, freezing helps retain the nutrient content of fruits and vegetables. However, some nutrients begin to break down when frozen produce is stored for more than a year. 🙂

  11. Jessica says:

    This smoothie needs to go into my regular rotation. Antioxidants, anti-inflammatory, *and* alkalizing?! You are speaking my language!!

  12. Susan Turner says:

    I like celery, so this smoothie sounds right up my alley. I never understood the “juicing celery” because it takes away the fiber— the best part! So blending the celery into the smoothie is def the way to go. Thank you for the weekly smoothie recipes to keep me inspired.
