Instructions

  1. Step 1: In a medium bowl, toss 400 g thinly sliced boneless beef sirloin 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 wok or large skillet over high heat until shimmering. Add the marinated beef and stir-fry for 3-4 minutes until browned and just cooked through. Remove beef from wok and set aside.
  3. Step 3: In the same wok, add 4 thinly sliced garlic cloves and 2 thinly sliced red chili peppers. Stir-fry for 30 seconds until fragrant.
  4. Step 4: Add 1 sliced red bell pepper and 3 sliced green onions; stir-fry for 2 minutes until vegetables are crisp-tender.
  5. Step 5: Return the beef to the wok, add 1 tsp brown sugar, 1 tsp sesame oil, and 1/2 tsp black pepper. Toss everything together and cook for another minute until flavors meld and the sauce slightly thickens. Serve hot over steamed rice or noodles.
