Yes, beet root is sweet.
Beetroot, which belongs to the same family as chard and spinach, has a sweet root that can be eaten. While both the leaves and the root are edible, the leaves tend to have a more bitter taste, while the root offers a distinctly sweet flavor profile. Beetroots are available year-round, but they are often sweetest and most tender when they are in season, which typically falls between June and October in the UK. This sweetness makes beetroot a versatile ingredient in both sweet and savory dishes.
