Smoothies are one of my favorite breakfasts or snacks to pack in fruits and veggies — whether it’s my creamy peanut butter banana smoothie or my peanut butter and jelly smoothie. But when it comes to green smoothie recipes, this is the one I make on repeat.

Have you ever sipped on a green smoothie and absolutely hated it? Same here. This green smoothie recipe is one you’ll actually crave. Trust me!

It’s sweet, light, refreshing, and easy to customize depending on what you have in your fridge or freezer (aka perfect for using up those last bits of spinach in the tub or that ripe banana sitting on the counter).

Ingredients Needed

A handful of simple, whole-food ingredients easily comes together to create this healthy green smoothie!

ingredients to make my go-to green smoothie recipe arranged on a cutting board

Spinach: I typically use fresh baby spinach, but frozen works just as well. It adds that beautiful green color without a super strong flavor.
Kale: Fresh curly kale is my go-to, but any variety works.
Banana: A ripe banana adds natural sweetness and that creamy texture we crave in smoothies. Frozen banana works great too, it just makes the smoothie thicker.
Frozen Mango: A freezer staple for me, especially during winter! Frozen mango chunks add natural sweetness and a burst of brightness. Frozen peaches or pineapple make great swaps too.
Non-Dairy Milk: I use soy milk for its protein and creaminess, but any dairy-free milk works.
Nut Butter: Not pictured above, but this is my little secret for an extra depth of flavor. Peanut butter is my favorite (it makes it taste like a peanut butter banana smoothie!) but almond butter or cashew butter also work.
Seeds: Optional, but I like adding ground flaxseeds, hemp seeds, and/or chia seeds for extra fiber and healthy fats.

Fresh Fruit vs. Frozen Fruit in Smoothies

I use a mix of fresh and frozen fruit in my smoothies for that thick, creamy texture, without the need for ice, which can water down the texture and flavor of your smoothie.

And fun fact: did you know that frozen fruit can have just as much nutritional value as fresh fruit? Frozen fruit is often frozen at peak ripeness, which means the nutrients are essentially locked in. So yes, you’re still getting all the goodness!

How to Make The Best Green Smoothie

Add all of the ingredients to a high-speed blender (I use a Vitamix, but a personal sized blender like a Nutribullet will work perfectly fine too). Blend until smooth and creamy. That’s it!

Green Smoothie Variations

One of the best parts about this green smoothie recipe is how customizable it is.

Fruit swaps: No frozen mango? Use frozen pineapple, peaches, or even oranges.
Change the greens: If you don’t have both spinach and kale, feel free to use all spinach or all kale.
Sprinkle in some seeds: Add chia seeds, hemp seeds, pumpkin seeds, or ground flaxseeds for an extra nutrient boost.
Protein boost: Add a scoop of your favorite protein powder.
Green tea lover? Sprinkle a teaspoon of matcha to your smoothie for extra green color and antioxidants.
Make it creamier: Add a scoop of your favorite yogurt for a creamier texture.
Adjust the sweetness: The riper your banana, the sweeter your smoothie. If you’d like it a little sweeter, add a drizzle of maple syrup, agave, or honey (if not vegan).
