Step 1

Set a large skillet, saute pan, or Dutch oven over medium-high heat. Add the ground beef and cook until no longer pink, breaking apart and stirring as the meat cooks.

Step 2

While the beef is cooking, combine the beef broth, oyster sauce, soy sauce, honey, rice vinegar, garlic powder, and red pepper flakes in a bowl or large measuring cup; set aside.

Step 3

After the beef is cooked, push it to the edges of the pan, add the garlic and ginger in the center, and stir for a minute or two until fragrant. Drain the grease from the pan. Add the sauce and the broccoli to the pan; stir to combine. Bring to a boil then reduce to a simmer. Cook for several minutes (using the cooking time on the package of frozen broccoli as a guide) and stir occasionally until the broccoli is cooked to your desired tenderness.

Step 4

In a small bowl, use a fork to whisk the cornstarch into the water until dissolved. Slowly pour the cornstarch slurry into the pan while stirring the beef and broccoli. Bring to a boil and cook for a minute or two, stirring occasionally, until the sauce is thickened. Stir in the sesame oil, if using, and serve hot over rice or noodles.
