Steps

Before you start
  • Keep the lid on the pot the whole time the sprouts cook, and never lift it early; this prevents the raw, fishy bean smell.
  • Have a colander and a bowl of cold water ready before you start cooking so the sprouts can be cooled right away.
  • Soybean sprouts have large yellow heads and long thin tails. Look for firm, white, fresh-smelling sprouts, not slimy ones.

  1. Clean the sprouts

    • Place the sprouts in a large bowl of cold water and swish with your hands.
    • Lift them into a colander, leaving husks and grit behind.
    • Pinch off any brown, dried tail tips.
    • Drain well.

    Ready when: Sprouts look clean and white with no loose husks or browned tips.

    Tip: Discard any sprouts that smell sour or feel slimy.

  2. Prep the aromatics

    • Thinly slice the scallions.
    • Mince the garlic very finely or grate it.
    • Set both in the large mixing bowl along with the sesame oil, fine sea salt, and gochugaru if using.

    Ready when: Garlic is fine enough to coat the sprouts without chunks.

  3. Steam-boil the sprouts

    • Put the sprouts in the pot with the ½ cup (120 ml) water and ½ tsp kosher salt.
    • Cover with the lid and set over medium-high heat.
    • Once you see steam escaping or hear a rolling boil (about 4 minutes), start timing.
    • Cook covered for 5 more minutes without lifting the lid.
    + Show details

    Ready when: Sprouts are tender but still crunchy when you bite a stem, with no raw bean smell.

    Tip: Lifting the lid early lets the raw, grassy smell stay in the sprouts.

  4. Drain and cool

    • Immediately pour the sprouts into the colander.
    • Rinse briefly under cold running water for about 20 seconds to stop the cooking.
    • Let drain for 5 minutes, then gently squeeze handfuls to remove excess water without crushing them.

    Ready when: Sprouts are cool to the touch and only slightly damp.

    Tip: Do not wring hard; crushed sprouts turn limp.

  5. Toss and season

    • Add the drained sprouts to the bowl with the seasonings.
    • Toss gently with clean hands or chopsticks for about 1 minute, lifting from the bottom, until every sprout is lightly glossy.
    • Taste and add a pinch more salt if needed.
    + Show details

    Ready when: Sprouts are evenly coated and taste nutty, garlicky, and lightly salty.

    Tip: Hands work best; spoons tend to break the sprouts.

  6. Finish and serve

    • Sprinkle with toasted sesame seeds, crushing them lightly between your fingers as you add them.
    • Toss once more and serve at room temperature or chilled.
    • For best flavor, rest 5 minutes before serving.

    Ready when: Salad is glossy with sesame seeds scattered throughout.

Tips
  • Keep the pot covered throughout cooking to avoid a raw bean smell.
  • Do not overcook; 5 minutes after steaming begins keeps a crisp bite.
  • Season while the sprouts are just barely warm or cool, and drain well so the salad doesn't get watery.
  • Use toasted sesame oil, not plain, for the characteristic nutty aroma.
Make ahead

"Cook, drain, and refrigerate the plain sprouts up to 1 day ahead in an airtight container. Toss with the seasonings within 1 hour of serving for the best crunch."

Storage & reheating

"Room temperature: up to 2 hours. Refrigerator: up to 3 days in an airtight container; the texture softens after day 2. Freezing is not recommended because the sprouts turn watery. Serve cold or at room temperature; no reheating needed."

Substitutions
  • soybean sprouts → mung bean sprouts. Cook only 2–3 minutes covered; they are more delicate and have a milder flavor.
  • toasted sesame seeds → untoasted sesame seeds, toasted in a dry skillet 2 minutes. Toast over medium-low heat until golden and fragrant.
  • fine sea salt → 1 tsp Korean soup soy sauce (guk-ganjang). Gives a deeper, savory flavor; reduce to ¼ tsp salt if needed.
  • gochugaru (Korean chili flakes) → pinch of cayenne or 1 thinly sliced red chili. Use sparingly as cayenne is hotter.
