This Japanese chicken rice bowl is the ultimate comfort food! It's wonderfully savory from the soy sauce, umami from the dashi, and a touch of sweetness from the onions. It's so easy and delicious, you'll want to make katsudon over and over again.
Start with toasting the panko bread crumbs. In a nonstick pan, add panko and cooking oil and heat the pan over medium heat. Occasionally stir the panko until it becomes golden brown, about 5 minutes. Turn off heat, transfer panko to a shallow bowl, and set aside while you prepare the chicken.
Next, pound the chicken to get it an even thickness. Take out one chicken breast, place on a cutting board, and lay down a piece of plastic wrap over top. Using a meat pounder or rolling pin, pound the chicken so it is an even thickness, about 1/2 inch. Once flattened, cut the chicken breast in half. Repeat with the second chicken filet. You should have four pieces of chicken.
Season the chicken pieces with salt and pepper on both sides.
Time to set up the dredging station. In a shallow dish, add flour. In a second shallow dish, combine eggs, water, and whisk. The third dish will have the reserved toasted panko bread crumbs.Take a chicken piece and coat it in flour, shaking off the excess. Next, dip the chicken into the egg mixture. Lastly, dip the chicken into the toasted panko, coating evenly. Set the chicken aside, and repeat with the other chicken pieces until all are coated.
Preheat the Air Fryer to 375°F. Place the chicken pieces on the Air Fryer basket. Bake the chicken for 10 minutes, flip the chicken and bake an additional 5 minutes. (See notes if you don't have an Air Fryer)
When the chicken is done, transfer to a cutting board and chop the chicken into bite-sized pieces. Set aside as you prepare the dashi broth mixture.
Prepare the katsudon sauce
In a container, whisk together dashi powder, water, soy sauce, and mirin. Set aside.
In a pan, toss in sliced onions with a teaspoon of oil and cook over medium heat for 2-3 minutes.
Next, add in the dashi mixture to the pan. Simmer for 5-7 minutes or until the onions are translucent.
Lay the chicken katsu neatly into the pan with the simmering dashi mixture. Let it simmer for about 1 minute.
Lower the heat to low. Slowly pour in the beaten eggs into the pan. Cover with a lid and let it simmer until the eggs are just cooked, about 2-3 minutes.
When the eggs are cooked, turn off the heat. Serve the entire mixture of steamed rice and enjoy!
Notes
If you don't have an Air Fryer, bake the breaded chicken at 400ºF for about 25 minutes, flipping halfway through
