I’ve always been a juice person, but I do love smoothies more. There’s something about the satisfying feeling a big smoothie gives you, especially one with kefir for that creamy texture and probiotic boost. Kefir is my all-time favorite dairy choice for smoothies! It has the tartness and tang of yogurt, but offers a much thinner consistency, making it perfect for blending. You can find it in most grocery stores, but if you prefer, you can substitute it with plain yogurt and a splash of water. I enjoy this recipe just like every other recipe on my site, so I hope you’ll give it a try.

GREEN SMOOTHIES: INGREDIENTS
- Baby spinach – A handful of spinach will pack in more nutrients without making the smoothie taste like spinach (promise!). Note: In this recipe the spinach is not frozen when added to the smoothie.
- Kefir – A great source of probiotics, calcium and protein.
- Cocoa powder – Cocoa powder contain important compounds that can benefit your health. Add around 1 Tsp of cacao powder (or cocoa powder), taste, and add more if needed.
- Banana – You can use fresh or frozen bananas – both will be creamy.
- Medjool Pitted dates – Dates are natural sweetener, bringing sweetness and nutrients to the smoothie. They’re source of essential nutrients such as fibre, vitamins, and minerals.
- Black Cumin Seeds to sprinkle (optional)
BENEFITS OF BLENDING DATES IN SMOOTHIES. Dates are a whole fruit whose delicious natural sugars are paired with good-for-you dietary fiber. They aren’t just a healthier, natural smoothie sweetener; they harness the power of potassium. Dates have 50% more potassium by weight than bananas.
SUBSTITUTIONS & ADDITIONS
This recipe is super versatile! Here are a few suggestions!
- Chia seeds/Flax seeds: these tiny seeds are packed with protein and nutrients – all you need is just 1 tablespoon for a nutrient boost.
- Add protein: A scoop of your favorite plain or vanilla protein powder will transform this smoothie recipe into a full meal.
- To replace the Medjool dates, you can use maple syrup. I love to use maple syrup as my unrefined sweetener for this recipe. However, feel free to use another liquid sweetener like organic honey.

HOW TO MAKE GREEN SMOOTHIE
- Begin by adding the kefir to the jar of a high-speed blender first, for easy blending. Then add the rest of the ingredients.
- Once the ingredients are in the blending container, secure the lid and blend until the mixture is smooth—start blending on low speed and gradually increase to high. Blend on high speed for 50-60 seconds or until the green smoothie is smooth.
- Pour the green smoothie into glasses and serve immediately. Enjoy!
TIPS FOR MAKING THE BEST GREEN SMOOTHIE
- Add the liquid first, then add the rest of the ingredients. This ensures the other ingredients don’t get stuck under the blades and creates a vortex that pulls everything down for a smooth blend, minimizing the need to stop and shake or stir the blender.
- Stir before you pour. Unblended Medjool dates can easily hide in this smoothie. Stir the mixture in the blender to ensure there are no unblended pieces before pouring it into the glass.

FAQs ABOUT GREEN SMOOTHIE

No, if you make this green smoothie recipe as it is written you will not be able to taste the spinach at all!
Will my smoothie taste watery if I use too much liquid?
If you add too much, it might! Start with less and blend, then adjust as needed.
What are black cumin seeds?
