Heat 1 tbsp vegetable oil in a large wok or skillet over high heat for exactly 1 minute. Add ground beef and cook, breaking it into small pieces as it browns, for 5-7 minutes until no pink remains. Season with ¼ tsp salt and white pepper. Transfer to a clean plate immediately.

Return the wok to high heat and add remaining 2 tbsp oil. Once shimmering, add minced garlic and ginger, stirring constantly for 30 seconds until fragrant. The timing here matters—burning these aromatics creates bitter notes that ruin the entire dish.

Add carrots, frozen mixed vegetables, and peas. Stir-fry for exactly 3 minutes, ensuring vegetables stay slightly firm and bright. They should have color and crunch, not become mushy.

Pour beaten eggs into the center of the wok and let them set for 10 seconds before scrambling throughout. Break into small curds while stirring. This method creates tender egg pieces rather than tough ribbons.

Add chilled rice to the wok, breaking up any clumps with your spatula. Stir-fry for 2 minutes, letting some rice grains make contact with the hot surface to develop slight browning and texture.

Return cooked ground beef to the wok. Pour soy sauce, oyster sauce, and sesame oil over the rice mixture. Toss vigorously for 2 minutes until every grain glistens and the sauce coats evenly. This step is where the beautiful beef fried rice truly comes together.

Add green onions and remaining ¼ tsp salt. Toss once more and taste, adjusting seasonings as needed. Transfer to serving dishes immediately while heat is still high for maximum aroma release.
