Mongolian Beef Recipe is the easiest way to have a flavorful and delicious restaurant-style dinner at home in just about 30 minutes!
In a medium saucepan over low/medium heat add the oil, followed by the garlic and ginger, cook and stir for 30 seconds and whisk in the brown sugar, soy sauce, and water. Cook until slightly thickened, about 5-10 minutes, set aside.
Add beef back to the skillet into the sauce mixture and cook over medium heat until sauce thickens, for about 2-3 minutes. Stir in green onions.
Garnish with sesame seeds (optional). Serve immediately over rice.
