Steps

1. Finely chop 1/4 onion. 【This is the key!】 Don't chop it too finely; cutting it slightly larger allows for a crisp texture.
   🕒 01:33
2. Cut 1/2 chicken breast (approx. 150g) into small pieces, about 1cm cubes.
   🕒 01:56
3. Lightly pound the cut chicken breast to tenderize it.
   🕒 02:17
4. Season the chicken breast with a pinch of salt and knead.
   🕒 02:29
5. Heat 1 tbsp salad oil in a frying pan and quickly stir-fry the chopped onion. 【This is the key!】 Don't overcook until sweet; leave it slightly crisp for texture.
   🕒 02:45
6. Add the seasoned chicken breast and stir-fry quickly, coating it with the onion.
   🕒 03:36
7. Add 2 tbsp or more tomato ketchup and 1 tbsp Worcestershire sauce, coat the chicken firmly, and evaporate the moisture to condense the flavor.
   🕒 04:15
8. Add 300g warm rice and mix the chicken sauce into the rice by pressing with a wooden spatula. No need to make it fluffy like fried rice.
   🕒 04:49
9. Add 1 tsp soy sauce to sharpen the flavor.
   🕒 05:32
10. Remove the chicken rice from the frying pan and transfer it to a serving dish. 【This is the key!】 Reducing the amount of ketchup prevents stickiness.
    🕒 05:58
11. Crack 4 eggs into a bowl, add a pinch of salt, and whisk until the whites and yolks are well combined.
    🕒 06:25
12. Melt 20g butter in the frying pan, making sure to coat the sides of the pan well with butter.
    🕒 07:40
13. Pour the beaten eggs into the frying pan and spread them evenly without stirring. Use the sides of the pan to create thickness and achieve a runny, semi-cooked egg. 【This is the key!】 Stirring the eggs can cause wrinkles on the surface. Cooking the edges in the pan creates thickness, making the egg pliable and less likely to tear.
    🕒 08:03
14. Place one portion of the prepared chicken rice onto the uncooked egg after removing it from the heat.
    🕒 08:45
15. Fold the front edge of the egg over the chicken rice, and using the side of the pan, maneuver the entire top portion of the egg over.
    🕒 09:04
16. Calmly slide the omurice onto a plate. If the shape is distorted, adjust it.
    🕒 09:35
17. Finish by generously drizzling tomato ketchup on top.
