Beet greens are the leafy tops of the beet plant and are often attached to fresh beets when sold. They have broad, tender green leaves and colorful stems that may range from red and purple to pink or yellow, depending on the variety of beet. Beet greens have an earthy, slightly sweet flavor with a mild bitterness that is often compared to Swiss chard or spinach. Younger leaves are generally more tender and mild, while larger, mature leaves have a stronger flavor and sturdier texture. Both the leaves and tender stems are edible, and cooking helps soften their texture and mellow their bitterness.
