Ingredients
  

For the Steak
  • 1.5 lbs flank steak or sirloin steak about 1-inch thick
For the Marinade
  • 2 stalks fresh lemongrass bottom 4 inches only, finely minced
  • 2 tbsp fresh ginger grated
  • 4 cloves garlic minced
  • 1/4 cup soy sauce low sodium recommended
  • 2 tbsp fish sauce
  • 2 tbsp lime juice freshly squeezed
  • 2 tbsp vegetable oil or other neutral oil
  • 1 tbsp brown sugar packed

Equipment

  • 1 Grill or Cast-Iron Skillet
  • 1 Large zip-top bag or shallow dish
  • 1 Cutting Board

Instructions
 

  1. In a medium bowl, whisk together the minced lemongrass, grated ginger, minced garlic, soy sauce, fish sauce, lime juice, vegetable oil, and brown sugar until the sugar is dissolved.
  2. Place the steak in a large zip-top bag or shallow dish. Pour the marinade over the steak, ensuring it is fully coated. Seal or cover and refrigerate for at least 2 hours and up to 6 hours.
  3. Preheat your outdoor grill or an indoor grill pan to high heat (450-500°F or 232-260°C).
  4. Remove the steak from the marinade, allowing any excess to drip off. Place the steak on the hot grill. Cook for 4-6 minutes per side for medium-rare, depending on thickness.
  5. Transfer the grilled steak to a cutting board and let it rest for 10 minutes. This is crucial for a juicy steak. After resting, slice the steak thinly against the grain.
  6. Serve immediately with your favorite sides like jasmine rice or a fresh salad.

Notes

Tip 1: For the best flavor, don't skip the marinating time. 4 hours is the sweet spot!
Tip 2: Always slice against the grain. For flank steak, this makes a huge difference in tenderness.
Tip 3: A very hot grill is key to getting a perfect sear without overcooking the inside.
