Microgreens: The Complete Guide to Nature’s Nutritional Powerhouses

What Are Microgreens?

Microgreens are young vegetable greens harvested 7–14 days after germination when they’ve developed their first true leaves. Unlike sprouts (germinated seeds eaten whole with roots), microgreens are grown in soil or other growing mediums, and only their stems and leaves are harvested.

These tiny plants represent the developmental stage between sprouts and baby greens, featuring a central stem, cotyledon leaves (seed leaves), and usually the first set of true leaves. Despite their small size, microgreens deliver concentrated flavor and exceptional nutritional density that often surpasses their fully mature counterparts.

First gaining popularity in California fine dining restaurants in the 1980s, microgreens have become accessible to home cooks seeking both culinary enhancement and nutritional benefits in their everyday meals.

Is it better to eat microgreens raw or cooked?

Research in the Journal of Food Science indicates raw consumption preserves maximum nutritional value, as heat-sensitive nutrients degrade during cooking. However, food scientist Dr. Rui Hai Liu notes that “light steaming or wilting can enhance the absorption of certain phytonutrients while maintaining acceptable levels of heat-sensitive compounds.”

Best practices based on food science research:

• Consume most microgreens raw when possible
• If cooking, use minimal heat for the shortest time possible
• Add microgreens at the end of cooking rather than at the beginning
• Consider using both raw and lightly cooked microgreens in the same dish
