How to Make Gas Grilled Marinated Flank Steak
Step 1: Marinate the Steak
Whisk marinade ingredients together. Place steak in a resealable bag or shallow dish and pour marinade over it.
Marinate for 2–8 hours (minimum 30 minutes; avoid over-marinating past 12 hours).
Step 2: Preheat the Gas Grill
Preheat grill to high heat (450–500°F / 230–260°C). Oil grates well.
Step 3: Grill the Steak
Remove steak from marinade and pat dry.
Grill:

Do not move steak while grilling—let it sear.

Rest steak 10 minutes. Slice thinly against the grain at a slight angle for maximum tenderness.
