Probiotic Kefir Smoothie
A quick and easy, nutrient-dense smoothie packed with probiotics from kefir and fiber from banana and flaxseed, perfect for a healthy start to your day or a refreshing snack.
For 1 serving
Gather all ingredients and ensure the banana is frozen for optimal smoothie texture and chill.
Add the plain kefir to the blender jar first, followed by the frozen banana, packed spinach, and ground flaxseed.
Pour in the water (or milk) and add the optional honey/maple syrup and vanilla extract.
Secure the lid on the blender tightly.
Start blending on a low speed to break down the larger ingredients, then gradually increase to high speed.
Blend for 45-60 seconds, or until the smoothie is completely smooth and creamy, with no visible spinach flecks. If too thick, add a splash more liquid; if too thin, add a few ice cubes.
Pour the freshly blended smoothie into a glass.
Serve immediately to enjoy its optimal texture and nutrient content.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1**Use frozen fruit:** Always use at least one frozen fruit (like banana) to achieve a thick, cold, and creamy smoothie without needing ice, which can dilute the flavor.
- 2**Layering matters:** Add liquids first, then soft ingredients (spinach), then frozen fruit, and finally powders (flaxseed). This helps the blender work more efficiently and prevents air pockets.
- 3**Adjust consistency:** If your smoothie is too thick, add a tablespoon of liquid at a time until desired consistency is reached. If it's too thin, add a few ice cubes or more frozen fruit.
- 4**Clean immediately:** Rinse your blender jar and lid immediately after pouring the smoothie to prevent ingredients from drying and sticking, making cleanup much easier.
Adapt it for your goals.
