10 - 1 1/2 tbsp oyster sauce
11 - 1 tbsp chili garlic sauce (adjust to taste)
12 - 1 tbsp rice vinegar

→ For Serving

16 - 1 1/2 cups jasmine or long-grain white rice
17 - 2 spring onions, sliced
18 - 1 tbsp toasted sesame seeds (optional)

# How To Make It:

01 - Cook jasmine or long-grain rice according to package instructions; keep warm.
02 - In a small bowl, combine soy sauce, oyster sauce, chili garlic sauce, rice vinegar, sugar, sesame oil, and cornstarch slurry; whisk until smooth and set aside.
03 - Heat 1 tablespoon vegetable oil in a large wok or skillet over high heat. Lay beef strips in a single layer and sear for 1 to 2 minutes until browned but not fully cooked. Remove beef and set aside.
04 - Add remaining 1 tablespoon vegetable oil to the pan. Stir fry onion, garlic, and ginger for 30 seconds until fragrant.
05 - Add bell peppers; stir fry for 2 to 3 minutes until tender-crisp.
06 - Return beef to the pan. Pour sauce over ingredients, tossing to coat evenly. Stir fry for an additional 2 to 3 minutes until sauce thickens and beef is fully cooked.
07 - Plate stir fry over steamed rice. Garnish with sliced spring onions and toasted sesame seeds, if desired.

# Expert Suggestions:

01 -
  • The whole meal comes together in under 40 minutes, leaving actual time to enjoy dinner instead of being chained to the stove.
  • Those charred edges on the beef and the snap still left in the peppers keep everything feeling alive rather than limp and exhausted.
  • One pan means one cleanup, which is genuinely the best kind of magic.
02 -
  • Don't crowd the beef in the pan when you're searing it; give it space or it'll steam instead of browning, which is the difference between restaurant food and regrettable dinner.
  • The sauce thickens quickly once the cornstarch heats up, so have everything else ready before you pour it in—there's no time to catch up.
  • High heat is your friend here; a timid flame makes everything taste dull and tired instead of alive.
03 -
  • Prepare everything before you start cooking—once you turn on the heat, the whole thing moves fast, and there's no time to chop peppers once the wok is screaming.
  • If your sauce seems too thin when you add it, let it bubble for an extra minute and the cornstarch will catch up; if it's too thick, a splash of water or broth loosens it back up.
