Ingredients

  • 1-1/2 lbs top sirloin or flank steak, thinly sliced against the grain
  • 1 tablespoon cornstarch
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon ground black pepper
  • 4-6 tablespoons vegetable oil, divided
  • 1 small sweet pepper, cut into 1/2-inch strips
  • 1 small sweet onion, thinly sliced
  • 1 small zucchini, cut into 1/2-inch cubes
  • 1 cup snow peas
  • 1 small Thai chili, minced (optional)
  • 3 medium cloves garlic, minced
  • 1/4 cup low-sodium soy sauce
  • 2 tablespoons oyster sauce
  • 1 tablespoon rice wine vinegar
  • 1 tablespoon fish sauce
  • 2 tablespoons light brown sugar
  • 1 cup lightly-packed fresh basil leaves
  • Salt and pepper to taste
  • Sliced green onions and steamed rice for serving

Instructions

  • Place beef in a large bowl and toss with cornstarch, salt, and pepper, until evenly coated.
  • Heat 2 tablespoons vegetable oil in a large skillet or wok until shimmery. Working in batches if needed, add beef in a single layer and sear until beef is golden brown. Repeat cooking with remaining beef, adding additional 1-2 tablespoons oil to pan as needed. Transfer beef to a bowl and set aside.
  • Heat remaining 2 tablespoons oil in same pan. Add pepper, onion, zucchini, snow peas, and chili to pan and cook 3-5 minutes until tender. Add garlic and cook 1 minute until fragrant. Remove from heat for a moment.
  • In a small bowl, whisk soy sauce, oyster sauce, rice vinegar, fish sauce, and brown sugar until smooth.
  • Return pan with vegetables to stovetop and set over medium-high heat. Add beef strips, sauce mixture, and basil leaves to pan and toss over medium-high heat 2-3 minutes until sauce is thickened and coating vegetables and beef.
  • Season beef with salt and pepper to taste if needed and serve with green onions and rice. Enjoy!
