Prepare Ingredients: Chop the kimchi, vegetables, and protein of choice. Make sure all ingredients are ready to use.
Heat the Pan: Heat a tablespoon of vegetable oil in a large skillet or wok over high heat.
Cook Vegetables and Kimchi: Add the chopped onion, carrot, and kimchi to the skillet. Stir-fry for 2-3 minutes until the vegetables start to soften and the kimchi becomes fragrant.
Add Rice and Protein: Add the cooked rice and your chosen protein to the skillet. Stir well to combine, breaking up any clumps of rice.
Season: Stir in gochujang, soy sauce, and kimchi juice. Mix everything well and continue stir-frying for another 3-4 minutes until everything is heated through and slightly crispy.
Finish: Drizzle sesame oil over the rice and give it a final stir. Garnish with toasted sesame seeds and a fried egg on top if desired.
