These are Japanese curry croquettes — mashed potato and seasoned ground meat, coated in panko and fried until genuinely crunchy. The filling is mild and savory, the crust stays crisp for a good while after frying, and the whole batch comes together in about 75 minutes. If you need something that feeds a group without requiring you to stand at the stove all evening, this is a solid choice.
Substitutions that actually work
- Japanese curry powder: This is the ingredient most people won’t have on hand. Standard Indian curry powder works but tastes sharper and less sweet. S&B brand Japanese curry powder is widely available online and in Asian grocery stores — worth buying if you plan to make this more than once.
- Ground meat: Ground beef or pork both work as written. Ground turkey is fine but produces a drier filling; add an extra teaspoon of oil when browning it.
- Panko breadcrumbs: Regular breadcrumbs will coat the croquettes, but the crust won’t be nearly as crunchy. Panko is the one swap not worth making.
- Tonkatsu sauce for serving: If you don’t have it, a mix of Worcestershire sauce and ketchup (roughly 2:1) gets you close enough.
The short version of why this works
Two things actually determine whether these turn out well. First, the mashed potato needs to be dry — watery mash makes the filling soft and the croquettes fall apart in the oil. Drain the potatoes thoroughly and let them steam off in the pot for a minute before mashing. Second, oil temperature matters more than timing. At 180°C (356°F), the panko crust sets fast and seals the filling inside; if the oil is too cool, the croquettes absorb grease and go soggy before they brown. Use a thermometer, or test with a pinch of panko — it should sizzle immediately and float to the surface.
Troubleshooting
- Croquettes burst open in the oil: The filling was too wet or too warm when shaped. Make sure the potato-meat mixture has cooled to room temperature before you form the patties, and press the panko coating on firmly so there are no gaps.
- Coating falls off during frying: The flour layer is the anchor. If you skip it or apply it too lightly, the egg won’t stick and the panko comes off. Dust each croquette thoroughly in flour first, shake off the excess, then proceed.
- Filling tastes bland after frying: Season the mashed potato itself with salt before combining it with the meat mixture. The potato is the bulk of the filling and needs its own seasoning, not just what carries over from the meat.
- Crust is brown but filling is cold in the center: Your croquettes are too thick, or the oil was too hot and browned the outside too quickly. Keep patties no thicker than 1 inch, and maintain steady oil temperature throughout the batch.
- Second batch is greasier than the first: Oil temperature drops each time you add croquettes. Let it return to 180°C between batches — skip the garnish on your serving plate and use that time to monitor the oil instead.
Make-ahead notes
The shaped, breaded croquettes (before frying) keep well in the fridge for up to 24 hours on a lined tray, loosely covered — this is the most useful make-ahead step if you’re cooking for a crowd. For longer storage, freeze them on the tray until solid, then transfer to a zip bag; they keep for up to one month and can go straight from frozen into hot oil, adding about 2 extra minutes to the frying time. Already-fried croquettes reheat best in an oven or air fryer at 190°C (375°F) for 8–10 minutes; microwaving makes the crust soft and is not recommended.
Japanese Curry Croquette
Ingredients
- 1 pound potatoes peeled and cut into small cubes
- 1 tablespoon vegetable oil
- 1 cup onion finely chopped
- ⅓ pound ground beef or pork high quality
- 2 tablespoons Japanese curry powder or more to taste
- 1 teaspoon soy sauce low-sodium preferred for balance
- 1 cup all-purpose flour for coating
- 2 large eggs beaten for coating
- 2 cups panko breadcrumbs for coating
- 3 cups vegetable oil for frying
Instructions
- Boil the potatoes: Place the cubed potatoes into a pot of salted water. Bring to boil and cook until tender, approximately 15-20 minutes. Drain well and mash until smooth.
- Prepare the filling: Heat 1 tablespoon of vegetable oil in a frying pan over medium heat. Add the onions and sauté until translucent. Add ground meat and cook until browned. Stir in the curry powder and soy sauce, cooking for an additional 2 minutes.
- Combine: Mix the mashed potatoes with the curry meat mixture until well combined, then let the mixture cool slightly.
- Shape the croquettes: Take portions of the mixture and shape them into small rounds or patties using your hands. Dust each with flour, dip into the beaten eggs, then coat generously in panko breadcrumbs.
- Fry the croquettes: Heat the vegetable oil in a deep pan to 180°C (356°F). Carefully add the croquettes in batches, frying until they are golden brown and crispy, approximately 3-4 minutes. Remove and drain on a paper towel.

Frequently asked questions
Can I bake these instead of frying them?
Yes, but the crust will be noticeably less crunchy. Brush or spray the breaded croquettes with oil and bake at 200°C (400°F) for 20–25 minutes, flipping once halfway through — an air fryer at the same temperature for 12–15 minutes gives a better result than a conventional oven.
How many croquettes does this recipe actually make?
The recipe card lists 4 servings, but the yield depends on how large you shape them. Using roughly 1/3 cup of filling per croquette, expect 8–10 patties from one batch — enough for 4 people as a side, or 2–3 as a main.
Can I double or triple the recipe for a party?
Doubling works without any issues — the filling scales directly. The only bottleneck is frying in batches; keep the batches small so the oil temperature stays consistent, and hold finished croquettes in a 120°C (250°F) oven on a wire rack while you finish the rest.
What type of potato works best?
Starchy potatoes like Russets or Yukon Golds produce a drier, fluffier mash that holds together better in the filling. Waxy potatoes (like red potatoes) tend to stay gluey and make the mixture harder to shape.
My local store doesn’t carry Japanese curry powder — is there a blend I can make at home?
A rough substitute is 1 tablespoon standard curry powder plus 1/4 teaspoon each of cinnamon and cardamom, which mimics the slightly sweeter, warmer profile of Japanese curry powder. It won’t be identical, but it’s much closer than plain curry powder on its own.
