Green Smoothie (aka Green Monster): How It’s Done

Step 2: Add Ingredients to Blender
In your blender, combine the frozen banana, baby spinach, peanut butter, almond milk, Greek yogurt, and protein powder (if using).
Step 3: Blend Until Smooth
Blend on high speed until all ingredients are well combined and the mixture is smooth. Depending on your blender, this could take anywhere from 30 seconds to a minute.
Step 4: Adjust Consistency
If the smoothie is too thick for your liking, add a little more almond milk until it reaches your desired consistency. Blend again briefly to mix.
Step 5: Taste and Adjust
Give your smoothie a quick taste. If you prefer it sweeter, feel free to add a little honey or another sweetener of your choice.

Year-Round Variations

- Add a scoop of cocoa powder for a chocolatey twist.
- Substitute almond milk with oat milk for a creamier texture.
- Incorporate seasonal fruits like mango or pineapple for a tropical flair.
- Try using different nut butters, such as almond or cashew, for varied flavors.
Frequent Missteps to Avoid
- Overpacking the spinach: Too much spinach can make the smoothie overly bitter. Stick to 2 cups for the best taste.
- Using too much liquid: Start with less liquid and add more as needed to avoid a watery texture.
- Not blending long enough: Ensure you blend until fully smooth to avoid chunks of spinach or banana.
Leftovers & Meal Prep
While smoothies are best enjoyed fresh, you can store leftovers in the fridge for up to 24 hours. Just give it a good shake or stir before drinking. For meal prep, consider portioning out your ingredients in advance. You can freeze the banana and spinach together in a bag, making it super easy to throw in the blender whenever you need a quick nutrition boost.
Frequently Asked Questions
