Homemade Korokke are Japanese potato and beef croquettes with a crispy panko coating and a soft, savory filling. Made with mashed potatoes, ground beef, onions, soy sauce, and mirin, they have a rich flavor and a satisfying texture. I coat the croquettes twice in panko before frying them until golden brown. They’re great as an appetizer, snack, or main dish served with shredded cabbage and tonkatsu sauce.
Ingredients
(Note: All ingredient amounts are listed in the recipe card below.)
800 g potatoes (about 1¾ pounds)
200 g ground beef (about 7 ounces)
1 onion
1 tablespoon soy sauce
1 tablespoon mirin
Salt, to taste
Black pepper, to taste
Seed oil, as needed
For Breading
3 eggs
All-purpose flour, as needed
Panko breadcrumbs, as needed
Salt, to taste
For Frying
– Seed oil, as needed
Directions
1. Cook the potatoes: I boil the potatoes in a pressure cooker for 15 minutes after it reaches pressure. I drain them, peel them while still hot, and mash them until smooth.
2. Sauté the onion: I heat a drizzle of seed oil in a nonstick skillet over medium heat. I add the chopped onion and sauté until softened.
3. Cook the beef: I add the ground beef to the skillet and cook over medium heat, stirring occasionally, until browned. I stir in the soy sauce and mirin to season the meat.
4. Prepare the filling: I transfer the cooked beef mixture to the mashed potatoes. I season with salt and pepper, then mix until the filling is soft but firm enough to shape.
5. Shape the croquettes: I divide the mixture into portions and shape them into round or slightly oval patties.
6. Bread the korokke: I coat each patty in all-purpose flour, dip it into the eggs beaten with a pinch of salt, and cover it with panko breadcrumbs. I dip it into the eggs again, then coat it with a second layer of panko.
7. Chill the croquettes: I arrange the breaded korokke on a plate and refrigerate them for about 20 minutes to help the coating set.
8. Heat the oil: I heat plenty of seed oil in a deep pan to 340°F. I use a kitchen thermometer to check the temperature before frying.
9. Fry the korokke: I fry 3–4 croquettes at a time until golden brown and crispy. I remove them with a slotted spoon and transfer them to paper towels to drain excess oil.
10. Serve: I arrange the korokke on a serving plate and serve them warm, with tonkatsu sauce or another preferred dipping sauce.

Variations
I can omit the beef for a potato-only version or add sautéed mushrooms, carrots, or corn to the filling. For a vegetarian version, I leave out the beef, while a vegan version can use aquafaba or a flour slurry instead of eggs for breading. For a lighter alternative to deep-frying, I can bake the croquettes at 400°F for 20–25 minutes or air-fry them at 375–400°F for 10–15 minutes, lightly coating them with oil and turning halfway through. I can also serve them with Japanese mayonnaise, ponzu, or teriyaki sauce instead of tonkatsu sauce.
Storage/Reheating
I let leftover korokke cool before transferring them to an airtight container and refrigerating them. To reheat, I use an oven or air fryer until the croquettes are heated through and the panko coating becomes crispy again. I avoid microwaving when possible because it can soften the breading. For make-ahead preparation, I can shape and bread the croquettes in advance, then keep them refrigerated until ready to fry.
FAQs
Can I make korokke without beef?
Yes, I can omit the ground beef and prepare potato korokke with onions and seasonings. I can also add mushrooms, carrots, or corn for extra flavor and texture.
Can I use a different type of ground meat?
Yes, ground chicken or turkey can be used instead of beef. I cook the meat thoroughly before combining it with the mashed potatoes.
Why do I need to chill korokke before frying?
I refrigerate the breaded croquettes for about 20 minutes to help the coating set and make them easier to handle during frying.
Can I bake korokke instead of frying?
Yes, I place the breaded croquettes on a parchment-lined baking sheet, lightly brush or spray them with oil, and bake at 400°F for 20–25 minutes, turning halfway through. The coating will be crispy but may be less golden than deep-fried korokke.
Can I cook korokke in an air fryer?
Yes, I lightly spray the breaded croquettes with oil and air-fry them at 375–400°F for 10–15 minutes, flipping halfway through.
Why are my korokke falling apart during frying?
Korokke can fall apart if the potato mixture is too soft or the coating doesn’t hold together. I make sure the filling is firm enough to shape and refrigerate the breaded croquettes before frying.
Can I use regular breadcrumbs instead of panko?
Yes, I can use regular breadcrumbs, but the coating will have a finer texture. I prefer panko because it creates the light, crispy exterior typical of Japanese korokke.
What temperature should the oil be for frying korokke?
I heat the oil to 340°F before adding the croquettes. I fry them in small batches to help maintain the oil temperature and achieve an evenly golden coating.
What sauce goes best with korokke?
Tonkatsu sauce is a traditional choice because its sweet and savory flavor complements the crispy croquettes. I can also serve them with Japanese mayonnaise, ponzu sauce, or ketchup.
Can I prepare korokke ahead of time?
Yes, I can cook the filling, shape the croquettes, and coat them in breadcrumbs ahead of time. I keep them refrigerated until ready to fry so the coating stays in place.

Ingredients
800 g potatoes (about 1¾ pounds)
200 g ground beef (about 7 ounces)
1 onion, finely chopped
1 tablespoon soy sauce
1 tablespoon mirin
Salt, to taste
Black pepper, to taste
Seed oil, as needed for sautéing
For the Breading:
3 eggs
All-purpose flour, as needed
Panko breadcrumbs, as needed
Salt, to taste
For Frying:
Seed oil, as needed for deep-frying
Instructions
Place the potatoes in a pressure cooker with enough water for cooking. Cook for approximately 15 minutes after the cooker reaches pressure, following the manufacturer’s instructions. Release the pressure safely, drain the potatoes, and peel them while still warm. Mash thoroughly until smooth and free of large lumps.
Heat a drizzle of seed oil in a nonstick skillet over medium heat. Add the finely chopped onion and sauté, stirring occasionally, until softened and translucent.
Add the ground beef to the skillet with the onions. Cook over medium heat, breaking the meat into small pieces with a spatula, until browned and fully cooked. Stir in the soy sauce and mirin, mixing well to distribute the seasonings evenly.
Transfer the cooked beef and onion mixture to the mashed potatoes. Season with salt and freshly ground black pepper to taste. Mix thoroughly until the ingredients are evenly combined and the filling is soft but firm enough to hold its shape.
Divide the potato and beef mixture into equal portions. Using your hands, shape each portion into a compact round or slightly oval patty, pressing gently to prevent cracks and ensure the croquettes hold together during frying.
Prepare three shallow bowls for breading. Place all-purpose flour in the first bowl, beat the eggs with a pinch of salt in the second bowl, and add panko breadcrumbs to the third bowl.
Coat each croquette lightly in flour, shaking off any excess. Dip it into the beaten eggs, allowing excess egg to drip off, then coat thoroughly with panko breadcrumbs. Dip the croquette into the beaten eggs a second time and finish with another layer of panko, pressing gently to help the breadcrumbs adhere.
Arrange the breaded korokke on a plate or parchment-lined tray in a single layer. Refrigerate for approximately 20 minutes to allow the coating to set and help the croquettes maintain their shape during frying.
Pour enough seed oil into a deep, heavy-bottomed pan for frying. Heat the oil to 340°F (170°C), checking the temperature with a kitchen thermometer to ensure consistent results.
Carefully lower 3–4 croquettes into the hot oil, depending on the size of the pan. Fry in small batches, turning gently as needed, until the exterior becomes evenly golden brown and crispy. Avoid overcrowding the pan, which can lower the oil temperature and produce greasy croquettes.
Remove the golden korokke from the oil using a slotted spoon. Transfer them to a paper towel-lined plate or wire rack to drain excess oil. Repeat with the remaining croquettes, allowing the oil to return to 340°F (170°C) between batches.
Arrange the freshly fried korokke on a serving platter and serve warm with tonkatsu sauce, shredded cabbage, or your favorite Japanese-style dipping sauce.
Notes
Potato-only variation: Omit the ground beef to make traditional potato korokke. Adjust the seasonings to taste and add extra sautéed onions if desired.
Vegetable additions: Mix sautéed mushrooms, finely diced carrots, or sweet corn into the potato filling for additional flavor, color, and texture.
Meat substitutions: Replace ground beef with ground chicken or turkey. Cook the meat thoroughly before combining it with the mashed potatoes.
Vegetarian option: Omit the beef and use vegetables or mushrooms in the filling. Check that the soy sauce, mirin, and serving sauce are suitable for your dietary preferences.
Vegan option: Omit the beef and replace the eggs used for breading with aquafaba or a flour-and-water slurry. Use vegetables or mushrooms for the filling.
Double breading tip: Coating the croquettes twice with egg and panko creates an extra-crispy exterior and helps keep the soft potato filling enclosed during frying.
Chilling tip: Refrigerate the breaded croquettes for at least 20 minutes before frying. This helps the coating adhere and reduces the risk of the korokke falling apart.
Filling consistency: The mashed potato mixture should be soft but firm enough to shape. Avoid adding excess liquid, which can make the croquettes difficult to handle.
Frying temperature: Maintain the oil at approximately 340°F (170°C). Fry in small batches to prevent the oil temperature from dropping too much.
Baked korokke: For a lighter alternative, arrange the breaded croquettes on a parchment-lined baking sheet, lightly brush or spray them with oil, and bake at 400°F (200°C) for 20–25 minutes, turning halfway through.
Air fryer method: Lightly spray the breaded croquettes with oil and air-fry at 375–400°F (190–200°C) for 10–15 minutes, flipping halfway through, until golden and heated through.
Breadcrumb substitutions: Regular breadcrumbs can replace panko, but the coating will be finer and less airy. Panko is recommended for the characteristic crispy Japanese korokke texture.
Sauce options: Serve with traditional tonkatsu sauce, Japanese mayonnaise, ponzu sauce, teriyaki sauce, or ketchup.
Serving suggestions: Pair korokke with finely shredded cabbage, steamed rice, miso soup, or a simple Japanese-style salad for a complete meal.
Make-ahead preparation: Prepare the filling, shape the croquettes, and coat them with breadcrumbs in advance. Keep refrigerated in an airtight container until ready to fry, preferably within 24 hours.
Refrigerator storage: Allow leftover korokke to cool, then transfer them to an airtight container and refrigerate for up to 3–4 days.
Freezing: Arrange uncooked breaded croquettes on a tray and freeze until firm. Transfer to a freezer-safe container or bag and freeze for up to 2 months. Cook thoroughly from frozen, allowing additional cooking time as needed.
Reheating: Reheat leftover korokke in an oven or air fryer until thoroughly heated and the panko coating becomes crispy again. Avoid microwaving when possible because it can soften the breading.
Nutrition information is estimated per serving based on 6 servings, approximate amounts of flour and panko, and oil absorbed during frying. Actual values vary depending on croquette size, breading quantity, and frying method.
