This vibrant kale spinach smoothie has become my daily ritual for packing in nutritious greens without sacrificing flavor. The combination of sweet frozen fruit with earthy greens creates a balanced breakfast or snack that energizes without the sugar crash.
I first created this smoothie during a health kick that I feared wouldn't last, but the delicious flavor kept me coming back. Now my entire family requests it, even my teenager who typically avoids anything green!
Ingredients
- Unsweetened almond milk: Provides the perfect neutral base without adding unnecessary sugars
- Spinach: Offers iron and folate while being incredibly mild in flavor
- Kale: Brings serious nutrition power with vitamins A, K, and C plus calcium
- Frozen banana: Creates creamy texture and natural sweetness
- Frozen mango or pineapple: Adds tropical flavor that masks the greens
- Peanut or almond butter: Contributes healthy fats and protein to keep you full
- Vegan vanilla protein powder: Boosts the staying power without dairy
- Cinnamon: Optional but adds warmth and helps stabilize blood sugar
Step-by-Step Instructions
- Pour the liquid first:
- Add almond milk to your blender container before any other ingredients. This technique helps the blender create a vortex that pulls other ingredients down toward the blades for smoother blending.
- Add remaining ingredients:
- Place all other ingredients on top of the liquid. Putting frozen items last helps weigh everything down toward the blades.
- Blend strategically:
- Start your blender on its lowest setting before gradually increasing to high power. This prevents air pockets from forming and ensures all ingredients incorporate evenly. Continue blending until completely smooth with no visible green flecks, about 45-60 seconds.
- Adjust consistency:
- If your smoothie seems too thick, gradually add more almond milk one tablespoon at a time until you reach your preferred texture. For thicker smoothies, add more frozen banana.

The frozen banana is truly the magic ingredient in this recipe. I discovered its importance accidentally when I ran out of fresh bananas and used a frozen one instead. The difference in creaminess was remarkable, and I have never gone back to making smoothies with fresh bananas since.
Meal Prep Magic
This smoothie works brilliantly as a meal prep option. You can prepare everything except the liquid the night before or even for the whole week. Simply measure all ingredients except the almond milk and place them in individual freezer bags or containers. When ready to blend, just dump the prepared ingredients into your blender with fresh liquid and enjoy with minimal morning effort.
Kid-Friendly Adjustments
If you have little ones who are suspicious of green drinks, this recipe can be easily modified. Adding a small handful of frozen blueberries will transform the color to purple while maintaining the nutrition. You can also start with more fruit and gradually increase the greens ratio as their palates adjust. My children now happily drink the fully green version after starting with the purple disguise technique.

Nutrition Boosters
Consider this smoothie a blank canvas for additional nutritional elements. Adding a tablespoon of chia seeds or ground flaxseed increases the omega-3 content without affecting flavor. A handful of cauliflower florets adds more vegetables while remaining tasteless in the final product. Even a quarter of an avocado can be incorporated for extra creaminess and healthy fats without significantly altering the taste profile.
Commonly Asked Questions
- → Can I use fresh fruit instead of frozen?
Yes, you can use fresh fruit instead of frozen, but you may want to add a few ice cubes to achieve the cold, thick consistency. Frozen banana specifically helps create the creamy texture, so consider freezing ripe bananas in advance for the best results.
- → How can I make this smoothie more kid-friendly?
For kids who aren't fans of green foods, add 1/4 cup of frozen blueberries which will turn the smoothie purple while still retaining the nutritional benefits. You can also increase the sweetness by using a riper banana or adding a touch of honey or maple syrup.
- → Can I prepare this smoothie in advance?
Yes! You can make this smoothie up to 1 day in advance and store it in the refrigerator. Alternatively, prep freezer packs by combining all ingredients except the liquid in freezer-safe bags or containers, then just add almond milk and blend when you're ready.
- → What can I substitute for the protein powder?
If you don't have protein powder, you can substitute with Greek yogurt, silken tofu, or hemp seeds to boost protein content. Each will alter the flavor and texture slightly, but will still provide protein benefits.
- → How can I adjust the calories in this smoothie?
For a lower-calorie version, omit the almond butter. To increase calories and make it more filling, double the nut butter to 2 tablespoons. You can also adjust the protein content by changing the amount of protein powder used.
- → What makes this smoothie so nutrient-dense?
The combination of kale and spinach provides vitamins A, C, K, folate, and minerals like iron and calcium. The banana offers potassium, the nut butter adds healthy fats and protein, while the protein powder boosts the protein content. Together, these ingredients create a balanced meal in a glass.
