The first time I put spinach in a smoothie, nearly 15 years ago, I had no idea what I was doing. I figured I could just add a handful of things to a blender and have it taste “good enough.” At first, the smoothie was too thick, so I added more milk. Then, it was too runny, so I added more frozen fruit.

Eventually, I wound up with way too much of a mediocre-tasting smoothie.

That’s why I’m sharing this spinach smoothie recipe. When you follow it closely, you’ll get delicious results on your first try, without the guesswork or winding up with too much. From there, you can customize it as you see fit!

“I made this last night, and my daughter (who generally shies away from anything “green” or with “green stuff in it”) drank this down and said; “Mom, where did you get this recipe?” I told her and her reply was; “Thank them!!!” She loved it. I’m so happy.” – Jaye

Spinach Banana Smoothie Ingredients

  • Fresh Baby Spinach. If this is one of your first green smoothie recipes, start with pre-washed baby spinach sold in the plastic clamshell boxes at the store. This is easy to grab and blends seamlessly into smoothies without adding flavor. If you don’t think you’ll use it all, you can also freeze it!
  • Frozen Banana. This frozen fruit adds a creamy texture and sweetness, especially if you freeze bananas that have lots of brown spots on their skin. (Here’s how to freeze bananas if you need tips.)
  • Almond Milk. I use almond milk to keep this recipe dairy-free, but any milk you prefer will work.
  • Hemp Hearts. This is an optional addition that adds plant-based protein. You could also use a scoop of collagen peptides for extra protein (with little added flavor.)
  • Nut Butter. I like to add a tablespoon of peanut butter for creaminess, but almond butter will work, too.
  • Cinnamon. If you like ground cinnamon, add it in! You could also use a splash of vanilla extract instead.

How to Make a Spinach Smoothie

Step 1:

If you don’t have a very powerful blender, I recommend starting off with just the spinach and milk. Blend those together until the spinach is pulverized, so you won’t have any chewy leaves in your final drink.

If you do have a powerful blender, you can skip straight to adding everything to it. Secure the lid and blend until smooth. Stop and scrape down the sides, if needed, to make sure everything is pulverized.

Note: The amount of liquid you may need will vary based on the type of blender you use and the size of the frozen banana each time. I’ve used the Vitamix 5200 and the Beast 850 blender for this, and occasionally I’ll need to add up to a quarter cup more liquid to make everything blend smoothly.

Step 2:

Taste the smoothie and make any adjustments, as needed. In these photos, I had to add a little extra milk to get the blender going (because the banana was a bit larger). Once it was smooth, I added a few ice cubes to make the smoothie slushy right before serving.

Adding ice can dilute the overall flavor, so don’t add too much! As soon as you’re happy with the texture and flavor, it’s ready to serve.

Storage Tip: If you need to store leftovers, they will keep in an airtight container in the fridge for up to 2 days, but the texture will not be the same. I recommend freezing leftovers in a mini popsicle mold, so you can enjoy a bite-sized treat later!

Spinach Smoothie Recipe FAQs

Is raw or cooked spinach better?

If you are concerned about oxalates in raw spinach, cooking it can reduce oxalate content by 30-87%. That said, raw spinach is very convenient (especially when you buy it prewashed) and can be frozen, to help avoid food waste, so either version will work in this smoothie recipe. If you use cooked spinach, it will shrink quite a bit, so you won’t want to use a full cup of cooked spinach in this recipe or the flavor will be too concentrated. Start with a 1/4 cup or 1/2 cup of cooked spinach, and adjust to taste as you go.

Can I use frozen spinach?

Store-bought frozen spinach is usually blanched before freezing, so it is an easy shortcut if you’d like to use cooked spinach in your smoothies. Just keep in mind that you’ll want to start with a smaller amount of the frozen spinach, since it’s so concentrated compared to fresh baby spinach. In this case, you may want to use a little more liquid for blending, too.

How do I make it thicker?

If you add too much liquid to this smoothie, you can thicken it by adding a handful of ice cubes, which will slightly dilute the flavor, or by adding a little extra frozen banana.

Do I have to use almond milk?

No, you can use any milk you prefer! Or even just water will work.

Servings:1

Ingredients
 
 

  • ½ cup almond milk , plus more as needed to blend
  • 1 to 2 cups baby spinach (see notes)
  • 1 tablespoon peanut butter (or almond butter)
  • 2 tablespoons hemp hearts
  • 1 frozen banana , sliced
  • ¼ teaspoon ground cinnamon

Instructions

  • If you don't have a powerful blender, start by adding the milk and spinach to it. Blend until the greens are totally pulverized for the best texture. (You can skip this step if using a high-speed blender, like a Vitamix.)
  • Add in the rest of the ingredients, and blend until very smooth. You may need to add up to a 1/4 cup more milk or water to help everything blend smoothly, depending on the size of the banana you use. The riper the banana you use, the sweeter this smoothie will be. If you need to add sweetness, you can always add a pitted Medjool date, or a splash of maple syrup, or honey (if not vegan), and blend again. Serve right away for the best taste and texture.
  • Leftover smoothie can be stored in an airtight container in the fridge for up to 48 hours, but the taste and texture will change over time. Be sure to check out the freezer bag tips in this post, for another make-ahead option.

Notes

Nutrition information is for the whole batch. This information is automatically calculated, and is just an estimate, not a guarantee.
To make a more filling smoothie, feel free to add another tablespoon of nut butter, or extra frozen fruit + more liquid to blend.
I typically use fresh baby spinach in this recipe, but you can use frozen spinach if you prefer. In that case, start with just a 1/4 cup of frozen spinach (since it is more concentrated). You can always add more, to taste, as you blend. See more tips in the full post.

  1. Tasted pretty good! The spinach and liquid trick before adding the other ingredients helped to make a really smooth drink. The smoothest I’ve had with my current blender.
