What if I told you that one of the biggest revolutions in modern cuisine and urban agriculture began with a happy accident? In a San Francisco restaurant kitchen in the early 1980s, a chef asked his grower to produce “baby greens” for his restaurant—but there was a misunderstanding. The grower delivered something much smaller than traditional baby greens: tiny plants with just their cotyledon leaves unfurled.

This mistake sparked curiosity rather than rejection. These tiny greens packed intense flavor, stunning visual appeal, and a delicacy that couldn’t be found in mature vegetables. A culinary innovation was born.

Food writer Pam Parseghian from Nation’s Restaurant News first documented these tiny greens in 1992, introducing the term “microgreens” to the culinary world and helping launch what would become a global phenomenon (MicroGreenSilo, 2024).

Starting in upscale California restaurants, these vibrant little greens slowly spread across the fine dining landscape. Chefs Craig Hartman and Michael Clark were among the first to experiment with microgreens, discovering that these tiny plants delivered concentrated flavors that could transform their dishes. According to John Lehndorff (2016), one supplier noted: “When we started out, we had maybe five varieties, and now we have over 100.”

For nearly two decades, microgreens remained primarily in upscale restaurant kitchens—little known to the average consumer but treasured by chefs for their flavor, color, and presentation possibilities. But something was brewing that would catapult these tiny greens from culinary secret to nutritional superstar.

Microgreens vs Sprouts: Origins of Two Tiny Greens

Long before microgreens made their debut, sprouts had established themselves in the American health food scene. Throughout the 1960s and 70s, sprouts—particularly alfalfa and mung bean—became synonymous with the growing natural foods movement. These germinated seeds, grown in water without soil, were easy to produce at home and offered a living food rich in enzymes.

The paths of sprouts and microgreens represent two different approaches to young plant foods. While they might look similar to the casual observer, they differ fundamentally in how they’re grown and harvested.

Sprouts are germinated seeds grown in water, usually in dark or low-light conditions. The entire sprout, including the seed, root, and shoot, is consumed after just 2-7 days of growth. They became popular during the health food boom of the 1960s and 70s, representing a living food that could be easily grown at home.

Microgreens, in contrast, are grown in soil or other growing media, require light for proper development, and are harvested at 7-21 days when they’ve developed their cotyledon leaves and sometimes first true leaves. Only the stem and leaves are harvested—the roots and seed hull remain in the growing medium.

At first, these differences seemed merely technical. Both products offered fresh, living greens that could be added to sandwiches, salads, and other dishes. But as we’ll discover, these differences would eventually lead to dramatically different trajectories for these two young plant foods.

The Scientific Breakthrough That Changed Everything

The year 2012 marked a turning point in the microgreens story—the moment these tiny greens transformed from chef’s secret to recognized nutritional powerhouses. A groundbreaking study conducted by researchers from the U.S. Department of Agriculture and the University of Maryland would forever change how we view these young plants.

The researchers analyzed the nutritional content of 25 commercially available microgreen varieties, measuring their levels of vitamins and carotenoids. What they found stunned even the scientists themselves: microgreens contained considerably higher levels of these nutrients—about five times greater on average—than their mature counterparts (USDA ARS, 2014).

Some varieties showed even more impressive results. Red cabbage microgreens contained 40 times more vitamin E and nearly six times more vitamin C than mature red cabbage. According to the study, cilantro microgreens had three times more beta-carotene than mature cilantro.

Dr. Gene Lester, a USDA plant physiologist who led the study, noted: “The microgreens were clearly more concentrated in nutrients. For example, red cabbage microgreens had a six-fold higher concentration of vitamin C than the mature vegetable” (USDA ARS, 2014).

The study was published in the Journal of Agricultural and Food Chemistry. It quickly garnered attention from both scientific and culinary communities. Suddenly, microgreens weren’t just pretty garnishes—they represented a new frontier in nutrient-dense foods.

This scientific validation catapulted microgreens from specialty food items to nutritional powerhouses practically overnight. Health publications began featuring articles about these newly discovered “superfoods.” Chefs who had already been using microgreens for their flavor and appearance now had a compelling nutritional story to tell as well.

Following the 2012 study, research into microgreens exploded. From approximately 300 scientific papers before the survey, the number has grown to over 3,000 today. Scientists began exploring everything from optimal growing conditions to the specific phytonutrient profiles of different varieties.

From Garnish to Superfood: The Culinary Revolution

The 2012 USDA study didn’t just excite scientists and health enthusiasts—it transformed how chefs thought about and used microgreens in their kitchens. What began as decorative garnishes evolved into featured ingredients that drove menu development and culinary innovation.

In the early days, microgreens were primarily valued for their visual impact. Their vibrant colors and delicate forms added a touch of elegance to plates at high-end restaurants. Chefs appreciated how these tiny greens could elevate the presentation of a dish without overwhelming the star ingredients.

But as awareness of their nutritional density grew, chefs began to see microgreens in a new light—as flavor-forward ingredients that could bring both sensory delight and dietary benefits to their creations.

This evolution in culinary use coincided with the growing farm-to-table movement, which emphasized fresh, local ingredients and transparent sourcing. Microgreens fit perfectly into this paradigm—they could be grown locally year-round, had a minimal carbon footprint, and offered exceptional freshness due to their short shelf life.

At Chicago’s award-winning Blackbird restaurant, Chef Ryan Pfeiffer emphasized that microgreens weren’t just decorative elements: “It’s common to see microgreens just kind of thrown on the plate. Here if it doesn’t have a purpose, it doesn’t go on the plate. Nothing is just a garnish” (Lehndorff, 2016).

The range of microgreen varieties expanded dramatically to meet culinary demand. Beyond the common varieties like pea shoots, radish, and arugula, specialty growers began offering exotic options like shiso, amaranth, and unique herb varieties. As David Sasuga of Fresh Origins noted, “We can work with a chef to create a blend grown for them and put their name on the label” (Lehndorff, 2016).

The versatility of microgreens also expanded their use beyond high-end dining. Health-focused cafes incorporated them into smoothies and grain bowls. Pizza restaurants added them to artisanal pies. Even cocktail bars got in on the trend, using microgreens in creative drinks.

Today, microgreens have become a fixture in culinary education. Cooking schools teach specific techniques for handling and incorporating these delicate greens. Food publications regularly feature recipes highlighting microgreens. What began as a chef’s secret has become a mainstream culinary ingredient.

Microgreens vs Sprouts: Why Chefs Made the Switch

The parallel stories of microgreens and sprouts took a decisive turn in the mid-1990s when food safety concerns began to cast a shadow over sprout production. While sprouts had enjoyed decades of popularity in the health food scene, a series of foodborne illness outbreaks linked to contaminated sprouts raised serious questions about their safety.

From 1996 to 2016, the FDA documented 46 outbreaks in the United States linked to sprouts, resulting in 2,474 illnesses, 187 hospitalizations, and three deaths (FDA, n.d.). The primary culprits were Salmonella and E. coli, which could contaminate seeds before sprouting and then proliferate rapidly in warm, wet growing conditions.

These safety concerns prompted many restaurants and food service operations to reconsider their use of raw sprouts. Some major chains removed sprouts from their menus entirely. Even health-focused establishments became wary of the potential risks.

Meanwhile, microgreens were emerging as a safer alternative. Their different growing method—in soil or other media rather than water, with only the above-ground portions harvested—significantly reduced the risk of bacterial contamination.

Chefs, always concerned about the safety of their ingredients, began to make the switch. Microgreens offered similar visual appeal and nutritional benefits without the food safety concerns that had become associated with sprouts.

The 2012 USDA study showing the exceptional nutritional content of microgreens further accelerated this shift. Chefs could now point to scientific evidence that microgreens weren’t just safer than sprouts—they were potentially more nutritious as well.

Beyond safety and nutrition, chefs discovered that microgreens offered greater culinary versatility. Their more developed leaves and stems held up better in various applications. As one industry publication noted, “Pea shoots are really popular because you can cook with them, and they won’t wilt” (Lehndorff, 2016).

The visual diversity of microgreens also gave them an edge in modern cuisine, where Instagram-worthy plating has become increasingly important. The vibrant purples, reds, and greens of different microgreen varieties offered chefs a broader palette for their culinary creations than the typically pale sprouts.

The Urban Farming Movement: Microgreens Lead the Way

The rise of microgreens coincided with—and in many ways catalyzed—a revolution in urban agriculture. Their unique growing requirements and high value made them ideally suited for city-based farming operations, helping to pioneer a new model of local food production.

Traditional agriculture requires substantial land, water, and time to grow crops to maturity. But microgreens upended this model. With their short growing cycle (7-21 days) and ability to be grown in stacked systems, they could produce significant yields in minimal space—a perfect match for urban environments where square footage comes at a premium.

Early urban microgreens farmers discovered they could operate profitable businesses from surprisingly small footprints. A few hundred square feet in a basement, warehouse, or even apartment could produce enough microgreens to supply multiple restaurants or farmers’ markets.

The economics of microgreens farming proved compelling. Their quick turnaround time meant faster cash flow than traditional farming. Their high market value—often selling for $30-60 per pound wholesale—created viable business models even at small scales. Their short shelf life necessitated local production, reducing competition from distant large-scale producers.

The controlled environment agriculture (CEA) industry embraced microgreens as ideal candidates for technological innovation. Vertical farming systems, which stack growing surfaces to maximize space efficiency, found microgreens to be ideally suited to their model. Their shallow root systems and short height meant many layers could be stacked in a single room, dramatically increasing yield per square foot.

Technology companies began developing specialized equipment for microgreens production—from automated seeding machines to perfectly calibrated LED lighting systems that optimize growth and nutritional content. These innovations further increased the efficiency and scalability of microgreens farming.

The environmental benefits of this new farming model were substantial. Growing food within urban centers dramatically reduced transportation emissions. Controlled environment systems used significantly less water than conventional agriculture—up to 95% less by some estimates. And many urban microgreens farms operated without chemical pesticides, producing clean, healthy food.
