Chop broccoli into bite-sized florets and set aside.

Heat 1 tablespoon of vegetable oil in a large skillet over medium-high heat until it shimmers.

Add ground beef to the hot skillet, breaking it apart, and cook for 5 to 7 minutes until fully browned.

Drain excess fat if needed, leaving a light coating in the pan.

Add minced garlic and ginger to cooked beef, stirring constantly for 30 seconds.

In a small bowl, whisk together soy sauce, oyster sauce, brown sugar, beef broth, and cornstarch.

Pour remaining 1 tablespoon of oil into the skillet, then add broccoli florets, tossing to combine, and cook for 2 to 3 minutes.

Pour the sauce mixture over the beef and broccoli, tossing until well coated.

Reduce heat to medium and simmer for 3 to 4 minutes until the sauce thickens and coats the back of a spoon.

Taste and adjust seasoning with salt, pepper, or red pepper flakes if desired.

Serve immediately over rice, noodles, or cauliflower rice.
