Turnip Microgreens: Taste, Nutrition & How to Use Them

Turnip and Bok Choy are actually the same species, Brassica rapa, just bred for entirely different traits, one for its swollen root, the other for its leaves. That's worth knowing on its own, but turnip has its own specific claim to fame too: its own particular set of Brassica compounds. Where mustard's pungency comes from sinigrin and broccoli's research interest centres on glucoraphanin, turnip greens are dominated by a different pair entirely, gluconapin and glucobrassicanapin. A systematic review of turnip greens phytochemistry confirms this specific profile (full review here).

Turnip sits in the Brassica family, alongside Mustard, Broccoli and Kale. This guide covers what turnip microgreens actually are, what's genuinely in them, and how they fit into a meal. For the basics on what separates a microgreen from a sprout or a baby green in the first place, start with What Are Microgreens?

What Is a Turnip Microgreen?

Turnip microgreens come from Brassica rapa subsp. rapa, the same species as Bok Choy, but a different subspecies entirely, bred over generations for a swollen edible root rather than a leafy top. At the microgreen stage, before any root has formed, it's the leaves that matter, small, tender and mildly peppery, gentler than mustard but with a similar family resemblance.

This is worth being precise about, since it changes which nutrient profile is actually relevant: a turnip microgreen approximates the leafy top of the plant, not the root, and the two parts are nutritionally quite different. Turnip greens are considerably more nutrient-dense than the root, especially for vitamin K, vitamin A, folate, calcium and lutein, while the root's standout nutrient is vitamin C. Judging a turnip microgreen against root-vegetable nutrition data would be comparing it to the wrong part of the plant.

Grown to microgreen size, turnip is typically ready in eight to twelve days.

Nutrient Profile

The systematic review cited above, which pooled data from eighteen separate studies on turnip greens, identified gluconapin as the most common glucosinolate reported across the literature, followed by glucobrassicanapin, both aliphatic compounds distinct from mustard's sinigrin and broccoli's glucoraphanin. The review also catalogued a wide range of flavonoids and other phenolic compounds in turnip greens, mainly quercetin, kaempferol and isorhamnetin derivatives.

On vitamin C: we don't have a turnip-microgreen-specific figure, so we're citing the greens rather than the root. USDA data lists mature turnip greens at around 60 mg vitamin C per 100 g, and a peer-reviewed comparative study of collard, mustard and turnip greens found total ascorbic acid of roughly 133 mg per 100 g in younger leaves versus 109 mg per 100 g in older leaves (full study here), which at least points in the direction of younger tissue carrying more, consistent with the general microgreen pattern, even without a dedicated turnip-microgreen assay.

On vitamin K: again no turnip-microgreen figure exists directly. Mature turnip greens run around 251 micrograms per 100 g by USDA figures, and the same collard/mustard/turnip greens study found phylloquinone averaging 435 to 459 micrograms per 100 g across young and old leaves. The closest true microgreen data point comes from a related Brassica rapa subspecies rather than turnip itself: choy sum microgreens have been reported at 377 micrograms per 100 g fresh weight in a 2025 review. Since choy sum is a different subspecies from turnip, even though it's the same species, we're presenting this as a related reference point rather than a turnip-specific number.

Turnip is also a source of vitamin C and vitamin K, consistent with other Brassica microgreens AgriZen grows.

Ratings above are qualitative rather than a single fixed figure, since glucosinolate and flavonoid levels vary considerably across turnip cultivars and growing conditions, and vitamin C/K figures above are for mature turnip greens rather than a directly measured microgreen value.

None of this amounts to a claim that turnip microgreens treat, prevent or manage any named health condition. Some published reviews of turnip attribute a wide range of therapeutic effects to it; we're deliberately not repeating those claims here. They're a nutrient-dense addition to a meal, best eaten as part of a varied diet.

Role in the Body

Turnip's glucosinolates, mainly gluconapin and glucobrassicanapin, break down into their own specific isothiocyanates when the plant is chewed, chopped or crushed, the same general mechanism as mustard's sinigrin and broccoli's glucoraphanin, just a different pair of starting compounds and end products. We go through this broader family of Brassica compounds, including how turnip's specific profile compares to its relatives, in Sulforaphane & Brassica Compounds: Role in the Body, Sources & Which Microgreens Have It, our dedicated nutrient deep-dive.

How to Use Turnip Microgreens

Turnip's mild pepperiness sits between bok choy's gentleness and mustard's sharpness, which makes it a flexible middle-ground option for warm, spiced dishes without overwhelming them.

A Quick Growing Note

AgriZen grows every variety the same way, indoors under LED light, watered with RO-purified water, from certified organic seed. We cover that full process, and what the organic-seed certification does and doesn't cover, in How Microgreens Are Grown: From Seed to Harvest.

Frequently Asked Questions

What do turnip microgreens taste like?

Mildly peppery, gentler than mustard but with a similar family resemblance, closer to a soft version of a radish bite.

Is turnip the same species as bok choy?

Yes. Both are Brassica rapa, just different subspecies bred for different traits, turnip for its root, bok choy for its leaves.

Should I compare turnip microgreens to the turnip root or the turnip greens?

The greens, not the root. A microgreen approximates the leafy top of the plant before any root has formed, and turnip greens are considerably more nutrient-dense than the root on most measures, especially vitamin K, vitamin A, folate and calcium. The root's standout nutrient is vitamin C.

Do turnip microgreens contain sulforaphane?

Not really. Turnip's dominant Brassica compounds are gluconapin and glucobrassicanapin, a different pair of glucosinolates from broccoli's glucoraphanin, which is the actual precursor to sulforaphane.

Which other AgriZen microgreens pair well with turnip?

Within the Brassica family, Mustard, Broccoli and Kale share a similar growing profile, with turnip sitting flavour-wise between bok choy's mildness and mustard's heat.

How long do turnip microgreens keep after delivery?

Like any fresh, ready-to-eat leafy product, they're best eaten within a few days of delivery and should be kept refrigerated in the meantime. For the full storage guidance, see How to Store Microgreens at Home to Make Them Last Longer.

A Small, Familiar-Sounding Addition

Turnip is a good closing note on just how much diversity sits inside a single Brassica species, sharing DNA with bok choy but carrying its own distinct set of compounds entirely, and best understood as a stand-in for the leafy greens rather than the root everyone knows it for. Grown indoors under LED light on AgriZen's shelving, watered with RO-purified water, and cut fresh to order, turnip's gentle peppery bite is a flexible, middle-ground addition to the menu.
