Start by finely slicing the cabbage, grating the carrot, and dicing the onion. This prep work is crucial for even cooking and texture.
In a large skillet or wok, heat the cooking oil over medium-high heat. You want the oil hot enough to sizzle when you add the vegetables.
Add the diced onion to the skillet and sauté for about 2-3 minutes until it becomes translucent. This step will build a lovely foundation for your fried rice.
Toss in the grated carrot and sliced cabbage. Stir-fry for about 5-7 minutes, or until the cabbage is wilted and tender but still has a nice crunch.
Next, add the cooked Jasmine rice to the skillet. Make sure to break up any clumps of rice to ensure even cooking. Stir everything together.
Add the unsalted butter, soy sauce, sesame oil, salt, and black pepper. Stir well to combine, letting the rice absorb the rich umami flavors. Cook for an additional 2-3 minutes.
Once everything is heated through and well combined, remove from heat. Taste and adjust seasoning if necessary. Serve hot, and enjoy your delicious Cabbage Fried Rice!
