Can I use a different cut of beef for bulgogi?
Yes. Rib eye, flank steak, or sirloin work well. Slice thinly (1/8 inch) against the grain for tenderness. New York strip, as in this recipe, has good marbling and texture.
What can I substitute for plum extract?
Use 1/4 cup honey, 2 tablespoons rice vinegar, or 2-3 tablespoons pear juice. Plum extract adds authentic tartness; substitutes will shift flavor slightly but work.
How long should bulgogi marinate?
2–4 hours for flavor, or overnight in the refrigerator. Longer marination (beyond 8 hours) can make the meat mushy due to the fruit enzymes.
How do I cook the marinated beef?
Cook on high heat in a cast-iron skillet or griddle for 1–2 minutes per side until lightly charred and cooked through. Beef bulgogi is best served rare to medium-rare.
Can I make bulgogi ahead?
Marinate the beef up to 24 hours ahead. Cook just before serving for best texture and char. Cooked bulgogi keeps refrigerated for 3 days.
