Spicy Stir-Fried Beef with Onions and Chilies

INGREDENT

• 1 lb (450g) beef sirloin or flank steak, thinly sliced
• 2 tablespoons soy sauce
• 1 tablespoon oyster sauce
• 1 tablespoon chili garlic sauce (or to taste)
• 1 tablespoon cornstarch
• 1 tablespoon vegetable oil (plus more for cooking)
• 1 large onion, sliced
• 2–3 red or green chilies, sliced thin (adjust to heat preference)
• 3 cloves garlic, minced
• 1 teaspoon ginger, minced
• 1 tablespoon rice vinegar or lime juice
• Salt and pepper, to taste
• Chopped green onions or cilantro for garnish (optional)

Instructions

1. Marinate the Beef:
   • In a bowl, combine the sliced beef with soy sauce, oyster sauce, chili garlic sauce, cornstarch, and 1 tablespoon oil.
   • Mix well and let marinate for at least 15–20 minutes.
2. Prepare the Stir-Fry:
   • Heat a wok or large skillet over high heat with a bit of oil.
   • Add the marinated beef in a single layer. Sear for 1–2 minutes per side until browned but not fully cooked. Remove and set aside.
3. Sauté Aromatics:
   • In the same pan, add a little more oil if needed. Sauté garlic, ginger, and chilies for 30 seconds until fragrant.
4. Add Onion:
   • Add the sliced onions and stir-fry until they begin to soften and slightly caramelize (about 2–3 minutes).
5. Combine and Finish:
   • Return the beef to the pan. Stir everything together and cook for another 1–2 minutes until beef is cooked through.
   • Splash in the rice vinegar or lime juice. Toss well to coat.
6. Serve:
   • Garnish with chopped green onions or cilantro if desired.
   • Serve hot with steamed rice or noodles.
