Ingredients

Main Ingredients:

  • 1 bunch spinach (about 400g/14oz)
  • 1 white part of green onion, finely chopped

Seasonings:

  • 1 tablespoon tuna extract
  • 1/2 tablespoon minced garlic
  • 1 tablespoon freshly ground sesame seeds
  • Fine salt to taste (about 1-2 pinches)
  • 1 tablespoon sesame oil

Instructions

  1. Prepare the spinach: Untie the spinach bunch and clean the roots thoroughly.


    Instead of removing the roots, use a knife to gently scrape off any dirt from the surface.

    Trim only the very bottom of the roots and remove any yellowed leaves.

  2. Cut and wash: Cut the spinach into 2-4 pieces depending on size. Thoroughly rinse under running water to remove all dirt and debris.



  3. Blanch the spinach:


    Bring 1.5 liters of water with 1 tablespoon of coarse salt to a rolling boil. Add the spinach and blanch for approximately 30 seconds (never exceed 40 seconds).

    This quick blanching preserves the vegetable's nutrients and maintains the pleasing crunch of the roots.

  4. Cool and drain:


    Immediately transfer the blanched spinach to cold water to stop the cooking process. Once cooled, squeeze firmly with both hands to remove excess water. Fluff and spread the spinach to make it easier to season.

  5. Prepare the seasonings:


    Freshly grind the sesame seeds and finely chop the white part of the green onion.


  6. Season the spinach:



    In a large mixing bowl, combine the spinach with 1 tablespoon chopped green onion, 1/2 tablespoon minced garlic, 1 tablespoon tuna extract, 1 tablespoon ground sesame seeds, and a pinch or two of fine salt.

  7. Mix thoroughly: Gently toss the spinach with the seasonings, ensuring every piece is evenly coated. Taste and adjust the salt if needed.

  8. Finish with sesame oil: Drizzle 1 tablespoon of sesame oil over the seasoned spinach and mix one final time until well incorporated.



Tips for Perfect Korean Spinach Side Dish

  • Grind sesame seeds fresh for a deeper nutty aroma and smoother texture.
  • Avoid overcooking: Keeping the blanching time short preserves color, sweetness, and texture.
  • Serve at room temperature for the best flavor.
  • This Korean spinach side dish pairs well with rice bowls, soups, and other mild vegetable sides.

Frequently Asked Questions

Can I prepare this spinach side dish in advance?
Yes. This dish actually tastes better after the flavors have time to meld. You can prepare it up to 3 days ahead and store it in an airtight container in the refrigerator.
What is tuna extract and what can I substitute?
Tuna extract is a Korean seasoning made from fermented tuna that adds savory umami depth. If unavailable, substitute with fish sauce, anchovy sauce, or a small amount of soy sauce (the flavor will be slightly different).
Do I need to remove the stems from the spinach?
No. The stems and roots contain much of the spinach’s natural sweetness and nutrients, especially in winter spinach. Just clean them thoroughly and enjoy their pleasant crunch.
How can I tell if winter spinach is fresh and high quality?
Look for spinach with thick, reddish roots, firm stems, and deep green leaves. Winter spinach grown in cooler coastal areas is especially prized for its natural sweetness.
Can I add other ingredients to this spinach side dish?
Yes, though this recipe focuses on the spinach itself. You can add a pinch of crushed red pepper flakes for heat or a small drizzle of honey for extra sweetness if desired.
