Beef and Broccoli Stir Fry

Instructions

1. Prepare the beef
   Place the thinly sliced flank steak in a bowl. In a small bowl, mix 1 tablespoon cornstarch with 1 tablespoon soy sauce to create a marinade. Pour over beef, toss to coat, and let sit for 10 minutes while preparing other ingredients.
2. Make the sauce
   In a medium bowl, whisk together the remaining soy sauce, oyster sauce, brown sugar, beef broth, and cornstarch until smooth. Set aside.
3. Cook the broccoli
   Heat 1 tablespoon of vegetable oil in a large wok or skillet over high heat. Add broccoli and stir-fry for 3 minutes until bright green and slightly tender. Add 2 tablespoons of water, cover, and steam for 1 minute. Transfer broccoli to a plate.
4. Cook the beef
   Add the remaining tablespoon of oil to the wok. Add the marinated beef in a single layer and let it sear for 1 minute without stirring. Then stir-fry for another 1-2 minutes until beef is just cooked through. Remove and set aside with the broccoli.
5. Combine aromatics
   In the same wok, add garlic, ginger, and red pepper flakes (if using). Stir-fry for 30 seconds until fragrant, being careful not to burn.
6. Bring it all together
   Pour the sauce mixture into the wok and bring to a simmer. Cook for 1-2 minutes until the sauce thickens. Return beef and broccoli to the wok, add sesame oil, and toss to coat everything evenly in the sauce.
7. Finish and serve
   Transfer to a serving dish and garnish with sliced green onions and toasted sesame seeds. Serve immediately with steamed rice.
