Ingredients

Instructions

  1. Step 1: In a medium bowl, toss 12 oz thinly sliced flank steak with 3 tbsp soy sauce and 1 tbsp cornstarch until evenly coated. Let marinate for 10 minutes.
  2. Step 2: Heat 2 tbsp vegetable oil in a large wok or skillet over high heat until shimmering. Add the marinated beef in a single layer and stir-fry for 2-3 minutes until browned but not fully cooked. Remove beef and set aside.
  3. Step 3: Add 1 large sliced red bell pepper and 1 large sliced green bell pepper to the same wok. Stir-fry for 3-4 minutes until edges start to char but peppers remain crisp.
  4. Step 4: Stir in 3 minced garlic cloves, 1 tsp ground cumin, 1 tsp ground coriander, and 1/4 tsp red chili flakes. Cook for 30 seconds until fragrant.
  5. Step 5: Return the beef to the wok and toss everything together for 1-2 minutes until the beef is cooked through and the sauce clings to the ingredients.
  6. Step 6: Remove from heat and drizzle 1 tsp sesame oil over the stir-fry. Garnish with 2 sliced green onions and serve immediately.
