First Step: PREPARE THE BEEF

1. Slice the Beef: Start by slicing the beef into thin strips against the grain. This will help ensure that the beef is tender and easy to chew. Flank steak works especially well for stir-frying because it’s lean yet tender when cut correctly.
2. Marinate the Beef: In a small bowl, mix together 2 tablespoons of soy sauce, 1 tablespoon of cornstarch, and 1 teaspoon of sesame oil. Add the beef strips to the bowl and toss to coat evenly. Let the beef marinate for 10-15 minutes to help tenderize it and absorb the flavors.

Second Step: PREPARE THE SAUCE

1. Mix the Sauce Ingredients: While the beef is marinating, prepare the sauce. In a bowl, combine 3 tablespoons soy sauce, 2 tablespoons oyster sauce, 1 tablespoon hoisin sauce, 1 tablespoon rice vinegar, 1 tablespoon brown sugar, and ½ cup beef broth. Stir to combine. In a separate small bowl, mix 1 tablespoon cornstarch with 1 tablespoon water to create a slurry, which will help thicken the sauce.
2. Set Aside: Once the sauce ingredients are mixed together, set the bowl aside until you’re ready to cook. The cornstarch slurry will be added to the sauce later to give it a thicker, glossy consistency.

Third Step: COOK THE BROCCOLI

1. Blanch the Broccoli: Bring a pot of water to a boil and add the broccoli florets. Let them cook for 1-2 minutes until they’re bright green and just tender. Drain the broccoli and set it aside.
2. Stir-Fry the Broccoli: Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the minced garlic and cook for 30 seconds, or until fragrant. Add the blanched broccoli and stir-fry for 2-3 minutes, just enough to heat it through and give it a slight char. Remove the broccoli from the pan and set it aside.

Fourth Step: COOK THE BEEF

1. Cook the Beef: In the same skillet or wok, add 1 tablespoon of vegetable oil and heat over medium-high heat. Add the marinated beef and stir-fry for 3-4 minutes until the beef is browned and cooked through. Be sure not to overcrowd the pan, as this will cause the beef to steam rather than sear. If necessary, cook the beef in batches.
2. Combine the Beef and Broccoli: Once the beef is cooked, return the broccoli to the skillet with the beef. Stir to combine and cook for an additional 1-2 minutes to allow the flavors to meld.

Fifth Step: MAKE THE SAUCE

1. Add the Sauce: Pour the prepared sauce over the beef and broccoli mixture. Stir to coat everything evenly.
2. Thicken the Sauce: Stir in the cornstarch slurry (1 tablespoon cornstarch mixed with 1 tablespoon water) and cook for an additional 1-2 minutes. The sauce will thicken, becoming glossy and coating the beef and broccoli in a beautiful sheen.
3. Taste and Adjust: Taste the sauce and adjust the seasoning if necessary. If you want it spicier, add a splash of chili sauce or red pepper flakes. If you prefer a sweeter sauce, add a little more sugar or hoisin sauce.

Final Step: SERVE AND ENJOY

1. Serve: Once the beef and broccoli are coated in the thickened sauce, remove the pan from the heat. Serve the dish immediately over a bed of steamed rice, or for a low-carb option, serve it with cauliflower rice.
2. Garnish: You can garnish your Beef with Broccoli with a sprinkle of sesame seeds, chopped green onions, or fresh cilantro for added color and flavor.
