Instructions
Thinly slice the white parts of the green onions. Cut the green parts into long strips (about 2 inches/5 cm) and set aside.
Smash the garlic cloves and finely chop them. Grate a small knob of ginger (2.5 teaspoons).
Make the sauce: In a small container, mix together the soy sauce, sugar, oyster sauce, chicken bouillon powder, dark soy sauce, light corn syrup, Shaoxing wine, black pepper, water, and cornstarch. Set aside.
In a wok (or pan), heat 1 tablespoons of oil over medium-high heat. Once hot, add the ground beef, breaking it up as it cooks. Sauté for 7 to 8 minutes until the beef is nicely browned. Remove from the wok and set aside.
To the same pan, add 2 tablespoons of oil and heat over medium. Add the white parts of the green onions, garlic, and ginger. Stir-fry for about 1 minute until fragrant.
Add the thicker parts of the green onions and the dried chilies (if using). Stir-fry for another 30 seconds.
Pour in the prepared sauce and simmer for 1 minute until the sauce thickens slightly. Return the beef to the pan and mix together for 1 minute. Turn the heat off, then add the remaining green onions and 1/2 tablespoons toasted sesame oil. Give it a final mix.
Spoon hot cooked rice into bowls and add a generous amount of the Mongolian Ground Beef on top. Garnish with sliced red chili if desired, and serve immediately.
