The first time someone saw my microgreens tray, they asked if I was sprouting beans. I get it. Small plants, small tray, no obvious context. But what was growing on that shelf wasn’t sprouts. It was microgreens. And the difference between the two matters more than most people realize.
Microgreens show up on restaurant plates as a colorful tangle that gets pushed to the side and ignored. That’s a mistake. They’re some of the most flavorful greens you can eat, they grow in under two weeks, and they pack more nutrients per gram than the full-sized plants they come from. I keep three trays in rotation on my growing shelf at all times, and they’ve become the one thing in my kitchen I never run out of.
What Are Microgreens, Exactly?
Microgreens are young vegetable and herb plants harvested at an early stage of growth. You plant the seeds, let them germinate, and cut them 7 to 14 days later when they’re 1 to 3 inches tall. At that point, the plant has a stem, a pair of cotyledon leaves (the first leaves that emerge from the seed), and sometimes a small set of true leaves just beginning to develop.
This isn’t a case of picking a plant too early. The cotyledon stage is the intended harvest point. It’s when flavor is most concentrated and nutrient density is highest. After this window, the plant redirects its energy into getting bigger rather than packing nutrition into a small frame.
You can grow microgreens from the seeds of almost any vegetable, herb, or grain. The most common types of microgreens come from the brassica family (broccoli, radish, cabbage, arugula) and larger-seeded plants like sunflower and peas. Each variety tastes like a stronger, more vivid version of the mature plant. Broccoli microgreens taste like broccoli, but cleaner. Radish microgreens hit with a pepper kick that the full-grown root barely hints at.
Microgreens vs Sprouts: How They’re Different
This is the question I hear most, and it’s worth getting right. Microgreens and sprouts are not the same thing. They look similar at a glance, and they both start from seeds. That’s where the similarity ends.
Sprouts are germinated seeds grown in water with little or no light. The whole thing is eaten: roots, seed hull, stem, everything. They’re ready in 3 to 5 days and tend to have a mild, watery crunch. Think mung bean sprouts or alfalfa sprouts from the grocery store salad bar.
Microgreens grow in soil (or a medium like coconut coir), need light to develop properly, and are harvested by cutting the stem just above the soil line. Only the stem and leaves go on your plate. They take 7 to 14 days and have much more distinct, stronger flavors than sprouts.
The food safety difference is significant. Sprouts grow in warm, wet, dark conditions that are ideal for bacterial growth. The FDA has issued specific guidance on sprout contamination risks, and sprouts have been linked to dozens of foodborne illness outbreaks in the US involving Salmonella and E. coli. Microgreens, by contrast, grow in soil with light and airflow. No foodborne illness outbreaks have been attributed to microgreens in the US to date.
Put simply: sprouts are seeds that barely got started. Microgreens are tiny plants that actually grew. I’ve eaten both, and the flavor comparison isn’t close. Sprouts are background texture. Microgreens are the main event.
Types of Microgreens Worth Trying
There are hundreds of varieties you can grow, but these five are the ones I come back to every week. Each has a different flavor, and between them you can cover everything from spicy to sweet to nutty.
Broccoli microgreens are the variety I’d pick if I could only grow one thing. The flavor is clean and mild with a slight peppery finish that doesn’t overpower whatever you’re eating. They’re also the most studied microgreen from a nutritional standpoint (more on that below). Growth is fast at 7 to 10 days, and the seeds are easy to handle. If you’re not sure where to start, start here.
Sunflower microgreens produce the thickest, crunchiest shoots of anything on my shelf. They taste like mild toasted sunflower seeds with a slight sweetness, and they’re substantial enough to eat on their own rather than just as a garnish. The yield per tray is the highest I’ve seen from any variety. They need 8 to 12 hours of soaking before planting, but the extra step pays off.
Radish microgreens are the speed demons. They germinate in 2 to 3 days and are ready to cut by day 7 or 8. The flavor is sharp and peppery, like a milder version of fresh horseradish. When I want to show someone that indoor growing actually produces food, I point to the radish tray. Nothing delivers visible results faster.
Arugula microgreens carry the same peppery bite as the mature plant, but with a nuttier, smoother finish. The sharpness that some people find too aggressive in full-grown arugula is dialed back at this stage. The leaves are delicate, so handle them gently at harvest. They work well on eggs, sandwiches, and flatbread.
Pea shoot microgreens are the sweetest option I grow. They taste like fresh peas straight from the garden, with a crisp, tender texture and curling tendrils that look good on anything. They grow taller than most microgreens (up to 4 inches) and take 8 to 14 days. I find the flavor hits its peak around day 10. Earlier than that, the shoots lack depth. After day 14, they start to get fibrous. I eat pea shoots off the tray more than any other variety.

Are Microgreens Actually Nutritious?
Yes. And the evidence is stronger than the typical “superfoods” marketing would lead you to expect.
In 2012, researchers at the University of Maryland and the USDA published a study in the Journal of Agricultural and Food Chemistry that tested 25 commercially grown microgreen varieties for vitamin and antioxidant content. The results were consistent: microgreens contained significantly higher concentrations of vitamins C, E, K, and beta carotene compared to the same plants at full maturity. The study found concentrations roughly five times greater overall, with some varieties showing even larger differences.
Red cabbage microgreens had the highest vitamin C levels in the study, at 147 milligrams per 100 grams (compared to 57 milligrams in mature red cabbage). Cilantro microgreens led in carotenoid content. Green daikon radish topped the list for both vitamin K and vitamin E.
Broccoli microgreens have drawn separate research attention for their sulforaphane content, a compound with antioxidant properties. Research led by Jed Fahey at Johns Hopkins found that young broccoli plants contain 20 to 50 times more sulforaphane than the mature vegetable.
The reason behind the numbers is straightforward. At the cotyledon stage, the plant is concentrating as much nutritional energy as possible into a small body. It’s building the fuel it needs to grow larger. When you harvest at that stage, you get that concentrated dose instead of letting the plant distribute it across full-sized leaves, stems, and roots.
This doesn’t mean microgreens replace a full plate of vegetables. You eat them in small quantities. But gram for gram, they deliver more vitamins than almost any other fresh produce you can grow at home.
Why Grow Microgreens at Home?
A small package of microgreens at the store costs $5 to $10 and lasts maybe a week in the fridge before it wilts. A single tray grown at home costs $2 to $4 in seeds and soil and produces three to four times as much. The economics start working in your favor after the first batch.
Freshness is the bigger advantage. Microgreens start losing their crunch and flavor within hours of being cut. Store-bought microgreens were harvested days ago, shipped in a cooler, and sat on a shelf. By the time you eat them, the best part is already gone. When you grow your own, you cut them seconds before they hit your plate. I didn’t understand how big the difference was until I tasted a radish microgreen straight off the tray next to one from a clamshell package I’d bought the same day. The homegrown one was sharper, crunchier, and more alive. The store one tasted tired.
The growing process takes almost no effort. A tray, some soil, seeds, and a windowsill. No garden. No balcony. No special equipment. The cycle from seeding to harvest is 7 to 14 days, and the daily time commitment is about two minutes of checking and watering. I keep three trays staggered at different growth stages so there’s always a fresh batch ready.

Frequently Asked Questions
Are Microgreens the Same as Sprouts?
No. Sprouts grow in water with no light and are eaten whole (roots, seed, stem) after 3 to 5 days. Microgreens grow in soil with light and are harvested by cutting only the stem and leaves after 7 to 14 days. The flavor, texture, nutritional profile, and food safety record are all different. Sprouts have been linked to dozens of foodborne illness outbreaks in the US. Microgreens have been linked to none.
Are Microgreens Safe to Eat Raw?
Yes. Growing in soil with light and airflow creates conditions that are much less hospitable to bacteria than the warm, wet, dark environment sprouts grow in. No foodborne illness outbreaks have been attributed to microgreens in the US. Rinse them before eating, the same way you’d rinse lettuce or herbs.
What Do Microgreens Taste Like?
Each variety tastes like a concentrated version of the mature plant. Radish microgreens are spicy and peppery. Sunflower shoots are nutty and crunchy. Pea shoots are sweet and fresh. Broccoli microgreens have a clean, mild vegetable flavor. Arugula is peppery with a nuttier edge. The flavors at this growth stage are more intense than what you get from the full-sized plant.
How Long Do Microgreens Last After Harvest?
About 5 to 7 days in the fridge if stored well. Rinse them, pat dry thoroughly with a towel, and keep them in a sealed container with a layer of paper towel to absorb excess moisture. Wet leaves are what cause them to break down fast, so drying them before storing is the key step.
