What is "Korokke"? The Ultimate Guide to the Japan's Croquettes

Korokke, the beloved Japanese potato croquette, offers a delightful blend of crispiness on the outside and a creamy, flavorful interior. Korokke's history is intertwined with Japan's cultural narrative. Its acceptance and transformation from a foreign import to a Japanese dish reflect the nation's ability to assimilate and make culinary innovations on its own. 

Korokke also has made its mark in various festivals and celebrations. Whether enjoyed during local matsuri (festivals) or as a festive snack during special occasions, korokke has become a dish associated with joyous moments, further embedding itself into the cultural fabric of Japan.

What is Korokke


Korokke, a delightful dish falling under the category of yoshoku (Western-influenced cuisine) shares similarities with the French croquette. These casual patties are coated in bread crumbs and are deep-fried to perfection, offering a crispy exterior that encases a variety of fillings, commonly mashed potatoes or cream sauce. The versatility of korokke then extends to a range of popular meat fillings, such as chopped beef, pork, chicken, or flavorful sausages. Vegetables like mashed or chopped potatoes, peas, and cabbage are also frequently used, while fish and cheese also find their place in this diverse culinary creation. Some variations even incorporate spices, eggs, or the unique addition of black pudding.

Although being deep-fried, korokke keep perfectly crisp long after cooking, making it suitable for both hot and room temperature enjoyment. Traditionally accompanied by tonkatsu sauce (a condiment reminiscent of Worcestershire sauce), korokke is often savored with chopsticks, unless purchased from a street vendor, where it might be conveniently wrapped in paper or served as a pan korokke (korokke sandwich).

Origins and Evolution


The history of korokke begins in the late 19th century during Japan's Meiji era (1868-1912). As Japan underwent a transformative period of modernization and openness to Western influence, the concept of korokke was introduced to Japan. Korokke made its initial appearance as a foreign delicacy enjoyed by the upper class of Japanese society.

Initially considered a luxury due to its foreign origin and the cost of imported ingredients, korokke underwent a gradual evolution during the Meiji era. Japanese chefs and home cooks embraced the concept, adapting it to local tastes and ingredients. The mashed potatoes or ground meat filling was combined with uniquely Japanese seasonings, and soon, regional variations of korokke began to emerge.

As the 20th century unfolded, korokke gained popularity beyond the elite circles and became a beloved dish among the general population. This transition can be attributed to a combination of factors, including the increased availability of ingredients, improvements in cooking technology, and the innate Japanese talent for culinary adaptation. Korokke found its way into homes, bento boxes, and eventually onto the bustling streets of Japan.

How to Make Korokke at Home?


Cooking perfect korokke at home involves a few key steps to ensure a crispy and delicious result. Here's a basic recipe and instructions for making korokke:


  • 4 large potatoes
  • 200g ground meat (beef, pork, or a mixture)
  • 1 onion, finely chopped
  • Salt and pepper to taste
  • Bread crumbs
  • Flour
  • 2-3 eggs (for coating)
  • Vegetable oil (for frying)


1. Prepare the filling:

   Peel and cut the potatoes into chunks. Boil them until soft, then mash them.

   In a pan, sauté the finely chopped onion pieces until translucent. Add the ground meat and cook until browned.

   Combine the mashed potatoes, cooked meat, salt, and pepper. Mix well until you have a cohesive filling.

2. Shape the korokke:

   Take a portion of the filling and shape it into flat, oval or rectangular patties. The size can vary based on your preference.

3. Coat the korokke:

   Prepare three separate bowls: one with flour, one with beaten eggs, and one with bread crumbs.

   Coat each korokke first in flour, then dip each into the beaten eggs, and finally coat it with bread crumbs, ensuring an even and thick coating.

4. Fry the korokke:

   Heat vegetable oil in a deep skillet or frying pan over medium heat. The oil should be hot but not smoking.

   Carefully place the korokke in the hot oil, taking care not to overfill the pan. Fry until golden brown on both sides.

5. Drain and serve:

   Once the korokke is golden and crispy, use a slotted spoon to remove them from the oil and place them on a plate lined with paper towels to drain excess oil.

6. Serve with tonkatsu sauce:

   Traditionally, korokke is served with tonkatsu sauce. Drizzle or dip the korokke in tonkatsu sauce before serving.

Tips for Success:

  • Oil Temperature: Maintain a consistent oil temperature to ensure even frying. It's generally around 350°F (175°C).  
  • Bread Crumbs: Use fresh bread crumbs for a crispier coating.
  • Chilling: If time allows, chill the shaped korokke in the refrigerator for about 30 minutes before frying. This helps the coating stick better during frying.
  • Experiment with Fillings: Get creative with your filling. Try different meats, seafood, or vegetables to customize the korokke to your liking.

By following these steps and tips, you can achieve perfectly crispy and delicious korokke right in your home kitchen. Enjoy your homemade korokke with rice, as a side dish, or even in a sandwich!
