Beef and Broccoli

Instructions

1. Marinate the beef
   In a medium bowl, combine 1 tablespoon of soy sauce, 1 teaspoon of cornstarch, and 1 tablespoon of water. Add the sliced beef, toss to coat, and let marinate for at least 10 minutes while preparing other ingredients.
2. Prepare the sauce
   In a small bowl, whisk together the remaining soy sauce, brown sugar, oyster sauce, rice vinegar, sesame oil, remaining cornstarch, water, and red pepper flakes if using. Set aside.
3. Blanch the broccoli
   Bring a pot of water to boil. Add broccoli florets and blanch for 2 minutes until bright green and slightly tender. Immediately transfer to an ice bath to stop cooking, then drain well.
4. Cook the beef
   Heat 2 tablespoons of oil in a large wok or skillet over high heat. Add beef in a single layer (work in batches if necessary) and cook for 1-2 minutes per side until browned but still slightly pink inside. Remove beef and set aside.
5. Stir-fry aromatics
   In the same pan, add remaining tablespoon of oil. Add minced garlic and grated ginger, stir-frying for 30 seconds until fragrant.
6. Combine and thicken
   Add blanched broccoli to the pan and stir-fry for 1 minute. Return beef to the pan, then pour in the prepared sauce. Stir continuously as the sauce thickens, about 1-2 minutes, ensuring everything is well coated.
7. Finish and serve
   Remove from heat once the sauce has thickened to desired consistency. Sprinkle with sesame seeds and serve immediately over steamed rice.
