- Reheat the rice in a microwave-safe dish, covering it with a damp paper towel to retain moisture. Heat in 1-minute intervals, stirring in between, until thoroughly warmed.

How to Reheat Leftovers
For a quick and easy method, use the microwave. Place the Japanese ketchup rice in a microwave-safe dish. Sprinkle a few drops of water over the rice to prevent it from drying out. Cover the dish with a microwave-safe lid or plastic wrap. Heat on medium power for 1-2 minutes, then stir. Continue heating in 30-second intervals until the rice is thoroughly warmed.

Stir frequently to ensure even heating. If the rice seems dry, add a splash of water or broth. Cook for about 5-7 minutes until the rice is heated through.
For an oven method, preheat your oven to 350°F (175°C). Spread the Japanese ketchup rice in an even layer in an oven-safe dish. Cover the dish with aluminum foil to retain moisture. Bake for about 15-20 minutes, stirring halfway through, until the rice is hot.
For a unique twist, consider using a steamer. Place the Japanese ketchup rice in a heatproof dish that fits inside your steamer. Steam for about 10 minutes or until the rice is thoroughly heated. This method helps retain the moisture and texture of the rice.
If you have an air fryer, preheat it to 350°F (175°C). Place the Japanese ketchup rice in an air fryer-safe dish. Cover the dish with aluminum foil to prevent the rice from drying out. Heat for about 5-7 minutes, stirring halfway through, until the rice is hot.
