Cooking Instructions

  • Begin by heating 1 tablespoon of vegetable oil in a hot skillet over medium-high heat.
  • Add the sirloin steak, cooking until it’s browned and caramelized, typically about 3-5 minutes. Remove and set aside.
  • In the same pan, add the remaining vegetable oil and sauté minced garlic and ginger for about 30 seconds, until fragrant.
  • Mix in the chopped bell peppers and onion; stir-fry until just tender-crisp, around 2-3 minutes.
  • Pour in the soy sauce, oyster sauce, hoisin sauce, and optional red pepper flakes, stirring well to combine.
  • Stir in the cornstarch slurry, mixing until it creates a thick, glossy glaze.
  • Return the beef to the pan, tossing everything together to coat in the sauce. Cook for an additional minute for flavors to meld.
  • Serve your Pepper Steak Stir-Fry hot, garnished with sesame seeds and green onions.

Notes

Avoid overcrowding the pan during cooking to maintain frying rather than steaming. For more flavor, consider marinating the steak in soy sauce for 15 minutes prior to cooking. Use a cast-iron skillet for optimal heat retention and searing.
