Ingredients

Instructions

  1. Step 1: Toss 12 oz thinly sliced flank steak with 1/2 tsp black pepper and set aside.
  2. Step 2: Heat 2 tbsp vegetable oil in a large wok or skillet over high heat until shimmering. Add the steak in a single layer and sear for 1-2 minutes without stirring, then stir-fry for an additional 1-2 minutes until browned but still tender. Remove steak and set aside.
  3. Step 3: In the same wok, add 2 minced garlic cloves and 1 tbsp grated fresh ginger, stirring for 30 seconds until fragrant.
  4. Step 4: Add 1 large sliced red bell pepper and 1 large sliced yellow bell pepper, stir-frying for 3-4 minutes until slightly softened but still crisp.
  5. Step 5: Return the steak to the wok along with 3 tbsp soy sauce, 1 tbsp sesame oil, 1 tsp brown sugar, and 1/4 tsp red pepper flakes. Stir well to combine.
  6. Step 6: Pour in 1 tsp cornstarch dissolved in 2 tbsp water, stirring continuously until the sauce thickens and coats the beef and vegetables, about 1 minute.
  7. Step 7: Remove from heat and sprinkle 3 sliced green onions on top before serving immediately with steamed rice or noodles.
