Classic Korean kimchi fried rice made with aged kimchi, cold leftover rice, green onion oil, and a fried egg on top. Bold, savory flavor and ready in about 20 minutes for an easy weeknight meal.
In a bowl, mix chopped kimchi with soy sauce, gochugaru (if using), sugar, and mayonnaise. Set aside.
Heat oil in a large skillet over medium-high heat. Add chopped green onion and cook for about 1 minute, until lightly golden and fragrant.
Add the seasoned kimchi to the skillet. Cook for 3–4 minutes, stirring often, until the moisture cooks off and the kimchi softens.
Add cold rice to the skillet. Gently break up clumps with the edge of a spatula and stir-fry until well combined and heated through. Remove from heat. Drizzle with sesame oil and sprinkle with toasted sesame seeds. Toss to combine.
Top with fried eggs and crumbled roasted seaweed snacks, if using. Serve hot.
