Ingredient & Substitution Notes

Visual list of ingredients for making a kale smoothie.
  • Frozen Banana: Frozen banana is essential for thick and creamy smoothies and is the perfect way to use up bananas you won’t be able to eat in time. Simply peel, break into chunks and freeze. If you can’t do banana or don’t like it, you can use frozen peach slices as an alternative.
  • Protein Powder: Use your choice of vegan vanilla protein powder to sweeten, thicken and boost the protein content. I like Vega, Iron Vegan, Nuzest, Outcast Mission and North Coast Naturals but any kind works!
  • Mango or Pineapple: Your choice! Both are a great addition and help sweeten the smoothie. Dates also work well as an additional sweetener.
  • Cinnamon: Also optional but adds a nice flavour alongside the date and banana.
  • Almond Butter: I like adding nut butters to smoothies for a bit of fats, creaminess and extra flavour. You can use peanut butter, almond butter, cashew butter, tahini or any other nut or seed butter you enjoy. I like it best with peanut butter!
  • Almond Milk: Any plant-based milk works here or try coconut water as an alternative! If you don’t want to use milk, plain water works too.
  • Kale and Spinach: Use raw kale and spinach or frozen. Feel free to mix and match the amounts and use all kale or spinach or swap for other greens like Swiss chard. Any kind of kale works here, such as common curly kale, lancinto kale (dinosaur kale, tuscan kale) or black/purple kale.

Smoothie Tips

Here are a few tips for smoothie success!

  • Add the liquid first.
  • Add the rest of the ingredients.
  • Start blending on low until it “catches”.
  • Slowly increase speed to high and blend briefly until completely smooth and creamy.
  • Avoid over-blending or it will start to melt the frozen ingredients.

Quick Tip: If you don’t have a high-speed blender, be sure to cut the fruit into smaller pieces and remove the kale leaves from the tough stem for easier blender.

How to Make in Advance

Here are three options to prep this smoothie in advance:

  1. Make the smoothie and pour into an airtight container. Store in the fridge overnight. It won’t be quite as thick in the morning but it will still taste delicious!
  2. Add everything but the almond milk to a freezer safe bag or container. When you’re ready, add the prepared container to your blender with milk and proceed!
  3. Make the smoothie and freeze it in a ice cube tray. Once frozen, pop the cubes into a freezer-safe bag. When you’re ready, add as many cubes as you like to a blender with a bit of liquid and blend it up! You can also pop the cubes into other smoothies.

Additions & Variations

  • The plant-based milk can be swapped for coconut water for a tropical flavour and boost in hydration. Plain water works too!
  • Try adding 1-2 tbsp chia seeds for additional fibre and nutrition.
  • If you don’t have both kale and spinach on hand, use 2 cups kale or 2 cups spinach or try other leafy greens like Swiss chard or arugula.
  • A squeeze of fresh lemon juice brightens up the flavour and adds even more vitamin C.
  • If you don’t have mango or pineapple on hand, a couple medjool dates or 1 tbsp of maple syrup or raw honey (not vegan) can help sweeten the smoothie.
  • Half a green apple makes a yummy addition too!
  • Plain or vanilla dairy-free yogurt makes a yummy and nutritious addition that’s great for digestion.

FAQs

Can I make this without banana?

You can substitute the banana with frozen peach slices, mango or pineapple. For less sugar and additional nutrients and fiber, you could also do half fruit and half frozen cauliflower or zucchini. Check my guide to adding vegetables to smoothies for more tips.

What else can I add to this smoothie?

For more volume, fiber and nutrition, try adding up to 1 cup cooked and frozen cauliflower, white sweet potato, squash or zucchini.

Note that, you will need additional liquid to account for the added volume. Other great additions include things like mushroom powders, chlorella, spirulina, hemp seeds, chia, flax or other “superfood” powders. Check out my post on the best superfoods to add to smoothies for more ideas.

Do I have to use protein powder?

I would recommend using it but if you’d like to make the smoothie without protein powder, replace it with an additional half a frozen banana, 1/2 cup mango or pineapple, 3-4 dates or cooked and frozen white sweet potato.

How can I make this low calorie?

For less calories, omit the amount butter.

Do I have to remove the kale leaves from the tough stems?

If you have a high-speed blender like a Vitamix or Blendtec, there is no need to remove the stems. They have just as much nutrition and fiber and the leaves! If you don’t have a high-speed blender, for easier blending, tear the leaves away from the tough stems and just use the leaves in the smoothie.

Is this smoothie good for weight loss?

There are a lot of factors that play a roll in weight loss but your overall caloric intake and energy expenditure are key. Green smoothies can be helpful as convenient, calorie-controlled meal replacements, if they keep you satisfied and you enjoy them.

This smoothie is nutritionally well-balanced and under 500 calories, so it could be used to replace a meal. However, if you’re enjoying it outside of meals and weight loss is a goal, I’d suggest making it into 2 servings or omitting the nut butter to reduce the overall calories.

Does this smoothie taste like kale and spinach?

Not all all. The sweet banana, mango and protein powder mask the taste of kale and spinach.
