Cut the onion into thin slices. Put oil in a frying pan and stir-fry over medium heat for 5 minutes.
Add the specified amount of water and bring it to a boil. Turn down the heat and cook for 15 minutes until the onion is tender.
Turn off the heat. Break the S&B Golden Curry Sauce Mix into pieces and add them to the pan. Stir and melt them completely. Turn on the heat again and simmer on low heat for 5 minutes until the sauce becomes thick.
【Chicken katsu】
Season the chicken with salt and pepper. Coat the chicken breast with flour, beaten egg, and panko, in this order.
Heat the oil in a large pot. (170°C) Deep-fry the breaded chicken breast from ① in the pot for 6 to 8 minutes. *Note that putting all of the pieces into the pot at once lowers the oil temperature.
Turn over the chicken katsu and once both sides are golden, take the chicken out of the pot and drain the excess oil.
【Cheese sauce】
Heat the butter in a frying pan.
Put flour into the frying pan in ① and mix well over low heat to keep it from burning.
Add the milk and once it blends thoroughly, add the cheese. Cook the mixture until the cheese is melted.
Put the rice and salad vegetables of your choice on a plate, pour the curry sauce over the rice, and top with the chicken katsu. Serve with the cheese sauce over the chicken katsu.
