  • 1 fresh red Thai chili, sliced

  • 5 cloves garlic, minced

  • Beef Seasoning Sauce:

    • 2 tbsp hoisin sauce

    • 1 tbsp dark soy sauce

    • 1 tbsp light soy sauce

    • 1 tsp gochujang or sambal (optional)

    • 5 tbsp chicken stock

    • 1 tbsp brown sugar

    • A handful of basil leaves (optional)

For the Potatoes:

  • 5 large potatoes, peeled and cut into chunks

  • 2 tbsp mayonnaise

For the Coating:

  • 2 eggs, lightly whisked

  • 3 cups Japanese panko crumbs

  • 1 cup all-purpose flour

Directions

  1. Prepare the Potatoes:
    Cook the potatoes in salted boiling water for 10-12 minutes until tender. Drain and return them to the warm pot. Shake the pot for a minute to dry out the potatoes, then mash them until smooth. Set aside.

  2. Cook the Beef Filling:
    Heat oil in a pan over high heat. Add garlic and sliced Thai chili and sauté for 30 seconds. Add the ground beef and cook, breaking it up for 2-3 minutes. Stir in the beef seasoning sauce and simmer for 1 minute until the sauce thickens. Add basil leaves (optional), then remove from heat and allow the mixture to cool. Remove basil leaves and chili before combining with the mashed potatoes.

  3. Combine Potatoes and Beef:
    Mix the cooled beef mixture with the mashed potatoes. Add mayonnaise and mix well. Spread the mixture onto a tray and press it into a rough 1.5-inch thick rectangle. Let it cool completely.

  4. Shape and Coat the Croquettes:
    Shape the potato mixture into oval or round portions. Dip each portion into flour, then egg, and finally coat with panko crumbs.

  5. Fry the Croquettes:
    Heat about ½ inch of oil in a large frying pan over medium-high heat. Fry the croquettes for 4 minutes on each side, or until golden brown. Drain on a wire rack or paper towels.

  6. Serve:
    Serve the croquettes with Tonkatsu sauce and a side of cabbage, tomato, or a fresh salad.

A Dish Rooted in Simplicity and Resourcefulness

One of the most appealing aspects of Japanese Potato Croquettes is their simplicity. The main ingredients—potatoes, ground beef, and a handful of seasonings—come together to create a dish that is not only delicious but also resourceful. These croquettes are an excellent way to repurpose leftover mashed potatoes, transforming them into a savory and satisfying snack. This aspect of the recipe makes it not only a tasty option but also a great way to reduce food waste. By combining leftover potatoes with seasoned ground beef and a crisp panko coating, you create a dish that’s both easy to prepare and rich in flavor.

In Japan, Korokke is often made with ground meat such as beef or pork, but you can easily adapt the recipe to your liking by using other proteins or even making them vegetarian with a plant-based filling. The combination of mashed potatoes and a seasoned filling makes this dish hearty and filling, perfect for a light snack or a more substantial meal.

The Rich and Savory Filling

The filling for these croquettes combines the creaminess of mashed potatoes with the savory flavors of seasoned ground beef. Ground beef is sautéed with garlic and fresh red Thai chili, adding a layer of spiciness to the mixture. The beef is then simmered in a savory sauce made with hoisin sauce, soy sauce, chicken stock, and brown sugar. This combination of ingredients results in a rich, umami-packed filling that perfectly complements the smoothness of the mashed potatoes.

The Thai chili adds a subtle heat that infuses the beef with a bold flavor, while the hoisin sauce and soy sauces contribute depth and a slight sweetness. The chicken stock ensures that the filling remains moist and flavorful, while the brown sugar rounds out the savory elements with a touch of sweetness. The basil leaves, although optional, provide a fresh herbal note that lightens the richness of the beef, making each bite even more flavorful.

Once the beef mixture is cooked and cooled, it’s combined with the mashed potatoes and a little mayonnaise. The mayonnaise adds creaminess to the potatoes, binding the mixture together and enhancing the overall texture. The result is a smooth, savory filling that is perfect for stuffing into croquette patties.

Creating the Perfect Croquette Coating

The key to achieving the perfect Japanese Potato Croquette is the crispy, golden coating. After shaping the potato and beef mixture into patties, the croquettes are coated in flour, egg, and panko breadcrumbs. The flour helps to bind the coating to the filling, while the egg ensures that the breadcrumbs adhere properly. The panko breadcrumbs, which are lighter and airier than traditional breadcrumbs, give the croquettes their signature crunch.

The panko coating creates a beautiful contrast between the crispy exterior and the soft, creamy interior. When fried, the breadcrumbs puff up and crisp to a golden-brown perfection, while the filling remains soft and tender. This texture contrast is what makes Korokke so satisfying to eat, as each bite offers a satisfying crunch followed by a creamy, flavorful filling. The coating also helps seal in the flavors of the seasoned filling, making every bite burst with savory goodness.

Frying to Perfection

The frying process is what brings these croquettes to life, transforming them from soft, raw patties into crispy, golden delights. A shallow fry in oil ensures that the croquettes cook evenly on all sides, becoming perfectly crispy without absorbing too much oil. The key is to maintain the oil temperature at medium-high heat, which allows the panko to brown quickly and evenly while ensuring the filling remains heated through. Frying for about 4 minutes on each side gives the croquettes the perfect golden-brown color and crispiness that are so characteristic of this dish.

Once fried, the croquettes should be placed on a wire rack or paper towels to drain any excess oil. This helps maintain their crispiness, preventing them from becoming soggy. The result is a beautifully fried croquette with a satisfying crunch that gives way to a soft, flavorful filling.

Serving and Pairing

Japanese Potato Croquettes are versatile and can be served in a variety of ways. One of the most popular accompaniments for these croquettes is Tonkatsu sauce, a sweet and savory sauce that pairs wonderfully with the crispy exterior of the croquettes. The rich, tangy flavor of the Tonkatsu sauce complements the savory filling, adding an extra layer of depth to the dish. If you prefer, you can also serve the croquettes with a simple side of fresh cabbage or a tomato salad, which adds a refreshing crunch that balances the richness of the croquettes.

Korokke is often served as a snack or appetizer in Japan, but it can easily be made into a main dish when paired with a salad or rice. Its versatility makes it an excellent option for a light lunch or dinner, as well as for parties and gatherings. These croquettes are sure to be a hit with anyone who enjoys crispy, flavorful bites and is looking for a delicious and satisfying dish.

A Dish for All Ages

One of the reasons why Japanese Potato Croquettes are so beloved is that they appeal to all ages. The combination of familiar ingredients like potatoes and beef, along with the crispy panko coating, makes these croquettes universally appealing. Children will love the soft, creamy filling and the crispy exterior, while adults will appreciate the savory flavors and the satisfying texture contrast. The spiciness of the Thai chili can be adjusted to suit different tastes, making this dish adaptable for those who prefer a milder version.

Additionally, these croquettes are a great way to introduce new flavors to those who may be unfamiliar with Japanese cuisine. The combination of familiar ingredients, such as potatoes and beef, with the unique umami flavors of the seasoning sauces, provides a gentle introduction to the bold and savory flavors of Japanese cooking.

The Art of Shaping Croquettes

Shaping the croquettes is an important step that ensures each piece has the perfect balance of filling and coating. While some people prefer to make perfectly round or oval-shaped croquettes, others enjoy experimenting with different shapes. The goal is to ensure that the filling is evenly distributed and that the patties are compact enough to hold their shape during frying. Pressing the potato mixture into a rough rectangle before shaping helps make the process easier and ensures that the croquettes cook evenly.

Conclusion

Japanese Potato Croquettes (Korokke) are a perfect combination of comfort and flavor, offering a delicious snack or appetizer that’s both crispy and tender. Filled with seasoned ground beef and mashed potatoes, these croquettes are satisfying on their own or paired with Tonkatsu sauce and a side of fresh salad.
