Slice 2 lbs flank steak into ¼-inch thick strips against the grain.
In a bowl, whisk together ½ tsp sesame oil, ½ cup soy sauce, ¼ cup brown sugar, 1/3 cup water, 1 Tbsp rice vinegar, and 1 Tbsp cornstarch. Set aside.
Add the sliced steak and 1/3 cup cornstarch to a zip-top bag. Shake until evenly coated.
Heat 2 Tbsp avocado oil in a large skillet over medium-high heat. Add beef in a single layer, cooking in batches if needed. Cook undisturbed for 3–4 minutes per side until browned and cooked through. Remove from the pan.
Add 1 Tbsp minced garlic and 1 tsp fresh minced ginger to the pan. Cook for 30–60 seconds until fragrant.
Pour in the sauce and cook for 2–3 minutes, stirring, until the sugar dissolves and the sauce thickens.
Return beef to the pan and toss to coat in the sauce.
Serve warm, topped with 1 Tbsp sesame seeds, if desired.
