Preheat the griddle: Turn your Blackstone griddle to medium-high heat. Drizzle sesame oil and spread it evenly using a spatula.
Scramble the eggs: Pour the beaten eggs onto the griddle and cook until just set. Break them into pieces and move them to one side.
Add veggies and rice: Toss in the butter, onions, peas, and carrots. Stir-fry for 2–3 minutes, then add the cold rice. Flatten it on the griddle to crisp up slightly.
Season and toss: Sprinkle garlic powder, soy sauce, black pepper, and oyster sauce. Mix everything well, breaking apart any rice clumps as you go.
Add protein (optional): If using chicken, shrimp, or steak, toss it in now and cook until heated through.
Combine everything: Mix the scrambled eggs back into the rice and toss to coat evenly with the sauce and butter.
Serve hot and enjoy: Garnish with sliced green onions or sesame seeds. Serve immediately with sides like Pollo Loco Recipe or Green Chutney Recipe for a full meal!
