Separate the green tops from the roots of the green onions. Thinly slice the roots and cut the green tops into 1-inch pieces. Heat a large nonstick pan over high heat and add 1 tablespoon sesame oil, swirling to coat. Once the oil is hot, place the ground beef in the center of the pan. Press it down and sear for 1 minute on each side without stirring. Then, break the meat into crumbles with a wooden spoon and cook until mostly browned.
Reduce heat to medium-high. Add 1 tablespoon sesame oil, the white parts of the green onions, garlic, and ginger. Sauté until the beef is fully browned and any liquid has been absorbed.
In a small bowl, whisk together cornstarch and chicken broth until smooth. Add the remaining 1 tablespoon sesame oil, hoisin sauce, brown sugar, soy sauce, and red pepper flakes (if using). Whisk until fully combined.
Pour sauce and the green tops of the green onions into the pan. Stir constantly until the sauce thickens and coats the beef evenly. Garnish with sesame seeds if desired.
Serve over cooked rice or alongside your favorite sides. Enjoy immediately!

Notes
Note 1: For easy prep, use Dorot garlic and ginger cubes (6 cubes of each = 2 tablespoons). Pre-minced garlic and ginger paste work too.Note 2: For the best flavor, I recommend using Lee Kum Kee hoisin sauce.Note 3: Serving Suggestions: Top with toasted sesame seeds and crushed red pepper flakes. Serve over boiled rice—it’s so easy:
Bring a large pot of water to a rolling boil.
Salt the water and add your desired amount of rice.
Boil for 10 minutes, taste for tenderness, then drain and fluff with a fork.
