Cook egg noodles according to package directions. Drain and set aside.
In a small bowl, whisk together soy sauce, oyster sauce, brown sugar, cornstarch, water, and beef broth until well combined. Set aside.
Heat vegetable oil in a large skillet or wok over medium-high heat. Add ground beef and cook, breaking it up with a spoon, until browned. Drain off any excess grease.
Add minced garlic and grated ginger to the skillet and cook for about 30 seconds until fragrant.
Pour the prepared sauce mixture over the ground beef. Stir well to coat. Cook for 1-2 minutes, or until the sauce has thickened.
Add the cooked noodles to the skillet with the beef and sauce. Toss gently to combine and ensure the noodles are coated.
Serve hot, garnished with sesame seeds and sliced green onions.
