Begin by gathering all the ingredients. In a blender or a food processor equipped with a metal blade, place the frozen strawberries at the base. Pour in the cranberry-raspberry juice and orange juice, followed by the vanilla yogurt on top.
Secure the lid and blend the mixture until smooth, stopping to scrape down the sides of the blender if necessary. Once the smoothie is fully blended and creamy, pour it into serving glasses.
Garnish each glass with a fresh strawberry, and enjoy your smoothie immediately for the best flavor and texture.
