Korean Radish Substitute — What Works (and What Doesn't)

Korean radish — called mu (무) — is shorter, rounder, and denser than the radishes you usually see at Western grocery stores. It has a firm, crunchy texture and a mild sweetness that makes it essential in dishes like kkakdugi, tteokguk, and galbitang. When you bite into a piece of braised mu, it's tender but still holds its shape. That texture is what makes it hard to replace.

But if you can't find it, here are the best alternatives I've used — and a couple I'd skip.

Daikon Radish — The Closest Substitute

Daikon is the first thing to reach for. It's from the same radish family, and in many recipes, you genuinely can't tell the difference. Most Asian grocery stores carry daikon even if they don't stock Korean radish specifically.

The main differences:

• Daikon is longer and thinner than Korean radish
• It has a slightly higher water content, so it's a touch less dense
• The flavor is very similar — mild, slightly peppery, with a hint of sweetness

Use daikon 1:1 in any recipe. For soups like tteokguk or galbitang, cut it into the same size pieces the recipe calls for and add it at the same time. It'll cook at roughly the same rate.

For kkakdugi (cubed radish kimchi), daikon works but the cubes may be slightly softer after fermenting since daikon holds less structure than mu. To compensate, cut your cubes a bit larger — maybe 1-inch instead of ¾-inch — so they maintain a satisfying crunch.

One tip: look for daikon that feels heavy for its size and has smooth, firm skin. Older daikon gets pithy and spongy inside, which is exactly what you don't want.

Turnip — Good for Cooked Dishes

Turnips are a surprisingly decent substitute in cooked dishes. They have a similar density to Korean radish and hold their shape well when simmered in soups and stews.

The flavor is different — turnips are earthier and slightly bitter compared to mu's clean sweetness. But when they're cooked in a rich broth like galbitang or a anchovy-based stock, that earthiness blends into the background.

Where turnips work well:

• Soups and stews (galbitang, beef bone broth)
• Braised dishes where the radish absorbs sauce
• Any recipe where the radish is cooked for 20+ minutes

Where they don't work:

• Raw preparations like dongchimi or fresh radish salad — the raw turnip flavor is too strong
• Kkakdugi — the texture is wrong and the bitterness clashes with the kimchi seasonings

Use turnips 1:1 by weight. Peel them well since the skin can be tough.

Jicama — Best for Raw and Crunchy Applications

Jicama is an interesting option. It's very crunchy, mildly sweet, and has almost no bitterness. It's nothing like radish botanically, but the texture is remarkably similar to raw Korean radish.

I'd use jicama for:

• Fresh radish salad (musaengchae) — the crunch is almost identical
• Quick pickled radish where texture matters more than authentic radish flavor
• Any raw preparation where you want that clean, crispy bite

Jicama doesn't cook well in soups — it gets weirdly starchy and loses its appeal. Keep it for cold or raw dishes only.

You can find jicama at most regular grocery stores in the produce section, often near the specialty root vegetables. It's usually pretty affordable.

Regular Red Radish — Not Ideal

The small round red radishes you see everywhere are technically radishes, but they're a poor substitute for mu. Here's why:

• They're much more peppery and sharp in flavor
• They're too small to cut into proper cubes or slices for most Korean recipes
• They get mushy quickly when cooked
• The red skin can bleed color into soups and sauces

If red radishes are truly all you have, they're usable in a pinch for soups — slice them thin and add them in the last 5 minutes of cooking so they don't turn to mush. But I'd call this a last resort, not a recommendation.

Watermelon Radish — A Decent Middle Ground

Watermelon radish (the one that's green on the outside and pink inside) is actually closer to Korean radish than regular red radish. It's denser, milder, and holds up better to cooking. The downside is that it'll turn your soup pink, which looks strange in a clear broth like galbitang.

For kkakdugi or pickled radish, watermelon radish works reasonably well. The pink color even looks kind of appealing once it's dressed in gochugaru.

Quick Reference Guide

• Kkakdugi: Daikon (cut slightly larger) or watermelon radish
• Tteokguk: Daikon, hands down
• Galbitang: Daikon or turnip
• Dongchimi: Daikon only — nothing else gives the right clean flavor for water kimchi
• Musaengchae (radish salad): Daikon or jicama
• Braised dishes: Daikon or turnip

Finding Korean Radish

If you're near an H Mart, 99 Ranch, or any Korean/Asian grocery store, you'll almost certainly find mu. It's usually in the produce section — look for the short, squat, greenish-white radishes that feel surprisingly heavy. A single Korean radish is typically enough for a big pot of soup or a batch of kkakdugi.

Korean radish keeps well in the fridge for 2-3 weeks if you wrap it in plastic wrap or a zip-top bag. If you find it, buy a couple — it's one of those vegetables that's worth having around because it shows up in so many Korean recipes.
