Ingredients

Scale
  • 1.5 lbs sirloin steak or ribeye, thinly sliced
  • 1 tablespoon soy sauce (for marinating)
  • 1 teaspoon cornstarch (for marinating)
  • 2 tablespoons vegetable oil, divided
  • 1 large onion, sliced
  • 2 bell peppers (red and green), sliced
  • 3 cloves garlic, minced
  • 1 cup beef broth
  • 1/4 cup soy sauce
  • 2 tablespoons oyster sauce
  • 1 tablespoon brown sugar
  • 1 teaspoon ground black pepper
  • 1 tablespoon cornstarch mixed with 2 tablespoons cold water (for slurry)
  • Cooked white rice, for serving

Instructions

  1. In a bowl, toss the thinly sliced steak with 1 tablespoon soy sauce and 1 teaspoon cornstarch. Let it sit for 10 minutes. This helps tenderize the beef.
  2. Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the steak in a single layer (work in batches if necessary) and cook for 1 to 2 minutes per side until browned. Remove the steak from the skillet and set aside.
  3. Add the remaining 1 tablespoon of oil to the skillet. Add the sliced onions and bell peppers. Stir fry for 4 to 5 minutes until the vegetables are tender-crisp.
  4. Add the minced garlic to the skillet and cook for 30 seconds until fragrant.
  5. In a small bowl, whisk together the beef broth, 1/4 cup soy sauce, oyster sauce, brown sugar, and ground black pepper to create the sauce. Pour the sauce mixture into the skillet with the vegetables. Bring the sauce to a simmer.
  6. Stir the cornstarch slurry and pour it into the simmering sauce. Stir constantly until the sauce thickens, about 1 minute.
  7. Return the cooked steak to the skillet. Toss everything together until the steak and vegetables are fully coated in the savory sauce. Cook for 1 minute to heat through.
  8. Remove the skillet from the heat. Serve your pepper steak immediately over hot white rice.

Notes

  • For extra flavor, marinate the beef for up to 30 minutes before cooking.
  • Use a mix of colorful bell peppers for visual appeal.
  • If you prefer a spicier dish, add 1/2 teaspoon of red pepper flakes to the sauce mixture.
