If you are using freshly cooked rice, spread it out on a baking sheet and let it cool and dry for 5-10 minutes.
Add a tablespoon of oil to a nonstick skillet and melt warm over medium heat. Once shimmering, add a cup of cooked rice. Let rice sit without stirring for 2-3 minutes.
Gently stir rice occasionally until it is crispy. Season rice with salt and serve with egg or any other topping.
To make a crispy rice patty:
Pack about one cup of rice into a patty that sticks together. Slide the patty into the skillet after the oil is warm. Let cook, undisturbed, for 3-4 minutes. Carefully flip with a spatula and let sit for another 3-4 minutes. Serve with toppings!
