Instructions

  1. Step 1: Thinly slice 12 oz flank steak across the grain into 1/4-inch strips. In a bowl, combine the beef with 1 tsp black pepper, 2 tbsp soy sauce, 1 tbsp fish sauce, and 1 tsp sugar. Toss to marinate for 20 minutes.
  2. Step 2: Slice 1 medium yellow onion into thin wedges and mince 2 garlic cloves. Chop 2 green onions into 1-inch pieces.
  3. Step 3: Heat 2 tbsp vegetable oil in a large skillet over high heat until shimmering. Add the minced garlic and sauté for 30 seconds until fragrant.
  4. Step 4: Add the marinated beef strips in a single layer and stir-fry for 3-4 minutes until browned but still juicy.
  5. Step 5: Add the sliced yellow onion and chopped green onions to the skillet and stir-fry for another 2 minutes until the onions soften but retain some crunch.
  6. Step 6: Remove from heat and serve immediately with steamed jasmine rice or your choice of side.
