Green Protein Smoothie with Watermelon Seeds
A vibrant green smoothie packed with plant-based protein from watermelon seeds, creamy frozen banana, and nutrient-rich spinach, perfect for a quick and energizing start to your day.
For 1 serving
Gather all ingredients. Ensure your banana is peeled and frozen solid for the best texture.
Into a high-speed blender, add the unsweetened almond milk first, followed by the fresh spinach, frozen banana, and hulled watermelon seed kernels.
If using, add the optional chia seeds and maple syrup at this stage.
Secure the lid tightly and blend on low speed to start, gradually increasing to high.
Continue blending for 1-2 minutes, or until the smoothie is completely smooth and creamy, with no visible chunks of spinach or seeds. You may need to stop and scrape down the sides with a spatula.
If the smoothie is too thick, add a splash more almond milk (1-2 tablespoons at a time) and blend again until desired consistency is reached.
Pour immediately into a glass and enjoy. Serve chilled.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1**Freeze Your Greens**: For an even colder and thicker smoothie, freeze your spinach ahead of time. Wash and dry it, then store in a freezer-safe bag.
- 2**High-Speed Blender is Key**: A powerful blender is crucial for breaking down the watermelon seeds and spinach into a super smooth, non-gritty consistency.
- 3**Adjust Sweetness**: Taste the smoothie before adding any sweetener. The frozen banana often provides enough natural sweetness.
- 4**Batch Prep**: Portion out dry ingredients (watermelon seeds, chia seeds) into small bags for quick smoothie assembly during busy mornings.
Adapt it for your goals.
