Heat butter (or vegetable oil) over medium heat in a large skillet or wok. Add the minced garlic and sauté for 1-2 minutes, stirring constantly to prevent burning [Note 5]. If you prefer aromatics like onions or ginger, sauté them now.
2 tablespoons butter, 3 garlic cloves
Push the garlic to the side of the pan and crack an egg into the center. Scramble until fully cooked, about 1 minute. Mix the egg with the garlic [Note 6].
1 large egg
Add the rice, using your spatula to break up any clumps. Fry over medium-high heat for 3-4 minutes, stirring occasionally. Allow some grains to crisp by letting them sit undisturbed for 1 minute at a time [Note 7].
2 cups cooked white rice
Drizzle the soy sauce and sesame oil evenly over the rice. Stir well to coat every grain. If using rice vinegar or lime juice, stir it in now for a bright, zesty touch.
1 tablespoon soy sauce, 1 tablespoon sesame oil, ½ teaspoon rice vinegar or lime juice
Increase the heat to medium-high. Fry the rice undisturbed for about 1 minute to develop golden, crispy edges. Stir once to flip and crisp the other side.
Taste and adjust with salt and pepper as needed [Note 8]. Garnish with green onions and sesame seeds if desired. Serve immediately.
1-2 green onions, 1 teaspoon sesame seeds, Salt and pepper
