Begin by boiling water in a large pot over high heat. Once boiling, add your preferred noodles and cook according to package instructions, usually around 8-10 minutes. Drain the noodles in a colander, rinsing them gently under cold water to stop the cooking process, then set aside while you prepare the rest of the dish.

In a medium bowl, whisk together the soy sauce, oyster sauce, honey, rice vinegar, and optional browning sauce until well combined.

In a small bowl, combine cornstarch and a few tablespoons of water until smooth. Mix this slurry with your prepared sauce, ensuring it’s evenly distributed.

Slice the flank steak or sirloin thinly against the grain. Marinate the beef with soy sauce, cornstarch, rice vinegar, and ginger in a large bowl for about 10 minutes.

Heat a wok or large skillet over high heat, adding sesame oil once hot. Add the marinated beef and sear for about 3-5 minutes, stirring gently until cooked through. Remove from the wok and set aside.

In the same wok, add more sesame oil if needed, then sauté onions, garlic, and ginger for 2-3 minutes until aromatic and translucent.

Add fresh broccoli florets to the wok and stir-fry for about 3-4 minutes until tender-crisp. Next, add the cooked noodles, gently mixing everything together.

Gradually pour the prepared sauce over the noodle and vegetable mixture, stirring continuously to ensure even coverage. Allow the sauce to bubble for about 2 minutes to thicken, then return the seared beef to the wok, warming it through.

Transfer your Beef and Broccoli Lo Mein Noodles to serving plates. Garnish with sesame seeds or sliced green onions and serve hot.
