Ingredients

Instructions

  1. Step 1: In a small bowl, whisk together 3 tablespoons soy sauce, 1 teaspoon brown sugar, 1 teaspoon cornstarch, 2 tablespoons water, and 1 tablespoon sesame oil to create a glossy stir-fry sauce; set aside.
  2. Step 2: Heat 2 tablespoons vegetable oil in a large skillet or wok over high heat until shimmering. Add 12 ounces thinly sliced flank steak and stir-fry for 2-3 minutes until just browned but slightly pink inside; remove and set aside.
  3. Step 3: In the same skillet, add minced 4 garlic cloves and sauté for 30 seconds until fragrant. Add julienned 1 red bell pepper and 1 green bell pepper and stir-fry for 3-4 minutes until tender-crisp.
  4. Step 4: Return the beef to the skillet along with the prepared sauce and 1/4 teaspoon crushed red pepper flakes, if using. Stir continuously for 1-2 minutes until the sauce thickens and coats the beef and vegetables.
  5. Step 5: Remove from heat and garnish with sliced 2 green onions before serving immediately over rice or noodles.
