First Step: Prepare ingredients and marinate the beef Slice 2 lbs of beef tenderloin thinly against the grain for maximum tenderness. Mix 2 tablespoons water, 1 tablespoon soy sauce, 1 tablespoon Chinese cooking wine (or substitute), and 2 tablespoons cornstarch in a bowl. Add the beef slices and coat evenly. Cover and marinate for 30 minutes to 1 hour in the refrigerator to infuse flavors and tenderize the meat.

Second Step: Prepare the sauce mixture In a separate bowl, whisk together ½ cup low sodium soy sauce, ⅔ cup water, ⅓ cup brown or coconut sugar, 2 tablespoons hoisin sauce (optional), 1 tablespoon oyster sauce, and ¾ tablespoon ground white pepper or red chili powder. Set this sauce aside; it will be added later to coat the beef and broccoli.

Third Step: Stir-fry the beef Heat ¼ cup vegetable oil in a wok or large skillet over medium heat. Working in batches to avoid overcrowding, stir-fry the marinated beef for about 2 minutes per batch until the edges become slightly crisped but beef remains tender. Remove cooked beef from the pan and set aside, maintaining warmth.

Fourth Step: Cook broccoli and aromatics Add 1 teaspoon sesame oil to the hot pan. Sauté 8 cloves minced garlic and ½ tablespoon minced ginger until fragrant, approximately 30 seconds to 1 minute. Add 1 head of broccoli florets and stir-fry for about 3 to 5 minutes, or until broccoli is tender but still vibrant green with some crunch.

Fifth Step: Combine beef and sauce Return the cooked beef to the pan with broccoli. Pour the pre-mixed sauce over the ingredients. Simmer everything together for approximately 2 minutes, stirring frequently, to allow flavors to meld and the beef to finish cooking.

Sixth Step: Thicken the sauce Quickly stir in the cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons water). Continue stirring constantly until the sauce thickens and coats the beef and broccoli evenly, about 1 minute. Add thinly sliced green onions and give a final toss.

Final Step: Serve and garnish Remove the stir-fry from heat and garnish with additional green onions if desired. Serve immediately over steamed rice, noodles, or alongside other vegetables for a satisfying meal. For dietary variations, replace soy sauce, beef, or enhance with different vegetable choices as needed.
