Creating this delightful Japanese Katsu Curry will be effortless if you follow these simple steps:

1. Prepare the Chicken: Flatten the chicken breasts by pounding them to an even thickness. Season with salt and pepper.
2. Coat the Chicken: Set up three bowls for breading. Place flour in the first, beat the eggs in the second, and put panko breadcrumbs in the third. Dredge each chicken breast in flour, dip into the egg, and then coat with panko breadcrumbs.
3. Fry the Chicken: Heat about half an inch of vegetable oil in a large skillet over medium heat. Once hot, carefully place the breaded chicken in the oil. Fry until golden brown on both sides, about 4-5 minutes per side. Remove and drain on paper towels.
4. Prepare the Curry Base: In the same skillet, remove excess oil, leaving about 1 tablespoon. Sauté the chopped onions until translucent. Add carrots and potatoes, cooking for another few minutes.
5. Add Broth and Seasoning: Pour in the chicken or vegetable broth and bring to a boil. Stir in curry powder, soy sauce, and ketchup. Allow to simmer until the vegetables are tender, about 15-20 minutes.
6. Adjust Seasoning: Taste the curry and adjust salt, pepper, or additional curry powder based on preference.
7. Slice the Chicken: While the curry is simmering, slice the fried chicken into strips.
8. Serve the Dish: Place a generous portion of rice on each plate. Spoon the curry sauce over the rice and lay the sliced chicken on top.

By following these steps, you'll create a plate of Japanese Katsu Curry that’s both visually appealing and filled with incredible flavors!
