Instructions

Step 1: Heat 2 tbsp vegetable oil in a large skillet over medium-high heat until shimmering. Add 2 minced lemongrass stalks, 3 minced garlic cloves, and 2 thinly sliced shallots, sautéing for 2-3 minutes until fragrant and the shallots soften.
Step 2: Add 1 lb thinly sliced flank steak to the skillet in a single layer and cook undisturbed for 2 minutes to caramelize, then stir and cook for another 2 minutes until browned.
Step 3: Sprinkle 2 tbsp brown sugar evenly over the beef, then add 3 tbsp fish sauce, 1 tbsp soy sauce, and 1/2 tsp freshly ground black pepper. Stir and cook for 2 more minutes until the sauce thickens slightly and coats the beef.
Step 4: Remove from heat and stir in 2 sliced green onions. Serve immediately over 2 cups steamed jasmine rice.
