Chicken Croquette (チキンコロッケ, Chikin Korokke) is a classic Japanese fried dish made with tender cooked chicken, fluffy mashed potatoes, onions, and seasonings, coated in crispy panko breadcrumbs and deep-fried until perfectly golden. As one of the many variations of Japan's beloved Korokke, Chicken Croquette is a popular comfort food served in homes, bakeries, school lunches, supermarkets, and bento boxes across the country.

The creamy potato filling and juicy chicken create a satisfying contrast with the light, crunchy panko crust. Often accompanied by shredded cabbage, Japanese Worcestershire-style tonkatsu sauce, or creamy mayonnaise, Chicken Croquettes are equally enjoyable as a snack, appetizer, side dish, or main course.

Simple to prepare and easy to customize, Chicken Croquette is a delicious example of everyday Japanese home cooking that appeals to all ages.

What is Chicken Croquette?

Chicken Croquette is a Japanese-style potato croquette made by combining mashed potatoes with finely chopped or shredded cooked chicken and sautéed onions. The mixture is shaped into patties, coated with flour, beaten egg, and panko breadcrumbs, then fried until crisp and golden.

Unlike Western croquettes that often use a thick cream sauce, Japanese Korokke usually rely on mashed potatoes for a light yet hearty filling.

Frequently Asked Questions

Can I use leftover roast or rotisserie chicken?

Yes. Leftover cooked chicken works perfectly, provided it is finely chopped or shredded and well-seasoned.

Can I bake Chicken Croquettes?

Yes. Brush them lightly with oil and bake at 200°C (400°F) for 20–25 minutes, turning halfway through. They can also be cooked in an air fryer at 190°C (375°F) for 12–15 minutes.

Why did my croquettes break while frying?

The filling may have been too wet, not chilled long enough, or the oil temperature may have been too low. Chilling and maintaining the correct frying temperature help prevent breakage.

Which potatoes are best?

Starchy potatoes such as Russet or Yukon Gold provide a fluffy texture and hold the filling together well.

Can I make Chicken Croquettes ahead of time?

Yes. Shape and bread the croquettes up to a day in advance and refrigerate them, or freeze them for longer storage. Fry or bake just before serving for the best results.
