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.

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.

  1. This sounds so yummy but I cannot find fresh fennel in my grocery store. Could I somehow substitute fennel seeds? Thanks

    1. Hi there Mandy, I’m sorry that you’re not having luck finding fennel. I’ve had that experience before – maybe looking at a different store if possible, because it really is a delicious ingredient. Yet, it’s not totally necessary for this recipe, so don’t stress!

    2. Hi there Mandy, I’m sorry that you’re not having luck finding fennel. I’ve had that experience before – maybe looking at a different store if possible, because it really is a delicious ingredient. Yet, it’s not totally necessary for this recipe, so don’t stress! I wouldn’t, however, recommend using fennel seeds as a substitute as I think it would affect the flavor and texture.

    This is a great recipe! The flavours blended together feel confusing for my brain – but in a good way!

    The only thing I didn’t enjoy was the texture. It feels a bit foamy for my tastes. But i don’t imagine that’s something crushed ice can’t remedy.

    1. 5 stars
      I’m having my first one now and I agree… what a great idea… crushed ice!

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

    1. 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!

  4. Greetings.
    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 homemade protein powder. 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.

    1. 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! 🙂

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

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

    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. 4 stars
    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!!!

    1. 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!

    1. 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! 🙂

  8. 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.


    1. 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. 🙂

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

  10. 5 stars
    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.
