Cast-iron Bok Choy Recipe

1. Rinse the baby bok choy under cold water to remove grit. Trim the stem ends and separate any very large heads in half lengthwise so most pieces are roughly the same thickness (about 1/2 inch stem to leaf). Pat dry thoroughly with paper towels or a clean kitchen towel — dryness ensures good searing.

2. Measure and combine the soy sauce, oyster sauce, rice vinegar, and stock (or water) in a small bowl; set near the stove. Slice the garlic thinly and julienne the ginger. Have butter, oils, and seasonings at hand.

3. Heat the skillet

Place a 10–12 inch cast-iron skillet over medium-high heat and let it get hot for 2–3 minutes until it is evenly heated. The skillet should be very hot but not smoking.

4. Sear bok choy (stem side down)

Add the neutral oil and swirl to coat the pan. Arrange the bok choy cut-side down in a single layer (stems to the center, leaves to the outside if space is limited). Press gently so the stem makes full contact with the pan. Let sear undisturbed for 2–3 minutes, until stems develop deep golden-brown color.

5. Add aromatics

Flip bok choy so cut side is up. Reduce heat to medium. Push bok choy toward the sides of the skillet and add the butter to the center. When butter foams, add the sliced garlic and julienned ginger. Sauté, stirring the garlic in the butter for about 30–45 seconds until fragrant and just beginning to color — do not burn.

6. Deglaze and steam

Pour the soy/oyster/vinegar/stock mixture into the pan, tilting the skillet slightly so liquid reaches the bottom and loosens browned bits. Immediately cover the skillet with a lid (or aluminum foil) to trap steam and cook for 1 to 2 minutes, until stems are tender when pierced with a paring knife but still crisp-tender.

7. Finish and season

Uncover and remove from heat. Drizzle the sesame oil over the bok choy and sprinkle the cracked black pepper and kosher salt evenly. Toss gently with tongs to coat and distribute the pan sauce. Taste and adjust seasoning: add a pinch more salt or a few drops of soy if needed.

8. Transfer bok choy to a warmed serving platter, spoon any remaining pan sauce over the top. Garnish with toasted sesame seeds, sliced scallions, and red pepper flakes if using. Serve immediately alongside rice or as a side to proteins.
