Why This Recipe Works

  • Easily customizable. By following this recipe, you’ll learn how easy it is to make a healthy green protein smoothie and customize it to your liking!
  • Super tasty green protein smoothie recipe. I used to think green smoothies had to be these vegetable blends with no flavor at all. I’m sure smoothies like that exist, but this is not one of them! This smoothie is packed with healthy, nutrient-rich spinach but the flavor also packs a punch. Not only is this green protein smoothie good for your body, it is so delicious! 
  • Zero added sugar. One of my favorite things about this smoothie recipe is that my kids think they are getting a shake, yet I know I’m feeding them a low-calorie green smoothie with zero added sugar. Did you get that? Zero added sugar

Ingredient Notes

Green Protein Smoothie ingredients on a gray background.
  • Spinach: I like to pack in the spinach to get a delicious spinach protein smoothie! However, if you’d prefer kale green smoothies, you can use kale instead.
  • Almond Milk: I like to use unsweetened almond milk, but if you want the regular, go for it! Also feel free to substitute a different milk if you’d prefer. Using a type of milk will give you more of a creamy texture than water.
  • Almond Butter: This gives us extra healthy protein and really adds a nice almond flavor.
  • Frozen Banana: I love frozen bananas in smoothies! It adds a great subtle flavor and creates an ice cream-like texture to your smoothies.
  • Protein Powder: Any brand of protein powder will work. But, if you are vegan, gluten or lactose intolerant, be sure to grab a protein powder that works for you! Oh, and I haven’t tried this recipe with chocolate protein powder, so no promises there ha 🙂  
  • Ground Cinnamon: You might think this is a weird add to a smoothie, but the touch of cinnamon in the smoothie adds a flavor complexity that is amazing!
  • Ice Cubes: Add ice cubes to get your desired consistency. Fun fact, ice cubes will actually reduce the amount of frothiness from the protein powder.

Step-by-Step Instructions

There’s a fairly basic structure to follow in creating a delicious green smoothie. I’ll break down the basics here. By following these basic elements, you can create your own green smoothie recipe, too!

  1. Pick a green vegetable base for your smoothie. We are using spinach, but you can adapt this recipe to add your own spin. If you love kale, add some kale in — or you can swap out the spinach for kale.
  2. Once you have your green base, add a frozen fruit. (You can use fresh fruit, but then you’ll want to add ice to create a frozen smoothie texture instead of a juice.) I like to add frozen bananas.

  1. Pick your liquid. You can choose water, milk, plant-based milk products, and more! I use almond milk.
  2. Add any other desired ingredients: Options include honey, cinnamon, protein powder, flax seeds, oats, etc. I always add cinnamon because I love the subtle flavor it adds.
  3. Add some ice cubes before blending. The ice cubes help reduce the amount of frothiness from the protein powder.
  4. Place all of the ingredients in a high-power blender and blend until smooth.

Recipe Tips

Plus, if you use a soy protein, this recipe is also a great vegan green smoothie. If you are vegan, just make sure you select a vegan protein powder option. Whey protein isn’t vegan-friendly, so be sure to double check.

If using or adding kale, be sure to remove the bulky stems prior to adding to the blender. As a note, wash all vegetables and fruits prior to blending.

Add some Greek yogurt for added probiotics and protein. You can also substitute the almond butter with a different nut butter if desired.

For best results, eat right after blending.

Make Ahead, Storing, and Freezing

If you want to make this high protein green smoothie ahead of time, I would recommend storing it in the freezer an then blending it again prior to eating. This is also a good method for if you have any leftover smoothie. Store it in the freezer and then add it back to the blender with enough almond milk to blend it to smoothie consistency.

FAQs

  • Can I use kale instead of spinach in my green smoothie?
  • Yes! Of course! You can add kale to the spinach or you can swap the spinach out for kale. As long as you have the leafy green base, you are good.

    What if I don’t have almond milk?

    If you don’t have almond milk, you can use the same measurement of water and add some whole almonds to the smoothie. 

    Can I use a different plant-based milk for the green smoothie?

    Definitely! You can use soy milk, oat milk, cashew milk, etc. Just remember, whatever other plant-based milk you choose, the smoothie will take on a bit of that flavor. With the almond butter in the smoothie, you’ll want to pick a milk option that will pair well with that. I, personally, probably wouldn’t use cashew milk. 

    Can green smoothies make you sick?

    Just like anything in life, it’s important to find balance. If you aren’t used to eating a lot of fiber-rich foods, then I probably wouldn’t suggest cutting everything out and only having green smoothies — I’d never recommend that anyway, there are too many good foods to enjoy! Since green smoothies are high in fiber, if you have too many in a short amount of time, you may have an upset stomach and diarrhea.

    Are green smoothies good for weight loss?

    Green smoothies should only be one part of the solution to a healthy lifestyle. If you only eat green smoothies, your body won’t be getting the variety and diversity of foods to get the nutrition it needs. As with everything, balance is key.
