Japanese Potato Croquette, known as Korokke (コロッケ), is one of Japan's most beloved comfort foods. Featuring a creamy mashed potato filling coated in crispy Japanese panko breadcrumbs and deep-fried until golden brown, these croquettes are crunchy on the outside and fluffy on the inside. They are commonly found in Japanese homes, supermarkets, bakeries, and bento boxes.

Whether served as a snack, appetizer, or main dish, homemade Japanese Potato Croquettes deliver a delicious balance of crispy texture and savory flavor.

What is Japanese Potato Croquette?

Korokke was inspired by French croquettes but evolved into a uniquely Japanese dish. Instead of using a creamy béchamel filling, Japanese potato croquettes are made with mashed potatoes mixed with sautéed onions and often ground meat. The patties are coated in flour, egg, and panko breadcrumbs before being fried until perfectly crisp.

They are typically enjoyed with tonkatsu sauce, shredded cabbage, and steamed rice.

Servings: 6 croquettes

Step 1: Cook the Potatoes

Peel the potatoes and cut them into evenly sized chunks.

Boil in salted water for about 15–20 minutes until fork-tender.

Drain thoroughly and allow excess moisture to evaporate for a few minutes.

Mash until smooth.

Step 2: Prepare the Filling

Heat vegetable oil and butter in a frying pan.

Cook the diced onion until soft and lightly golden.

If using ground meat, add it and cook until browned.

Season with soy sauce, salt, and black pepper.

Allow the mixture to cool slightly.

Step 3: Combine

Mix the mashed potatoes with the onion and meat mixture.

Taste and adjust the seasoning if needed.

Let the mixture cool enough to handle.

Step 4: Shape the Croquettes

Divide the mixture into six equal portions.

Shape into oval or round patties about 1 inch thick.

Step 5: Bread the Croquettes

Coat each patty in flour.

Dip into the beaten eggs.

Cover evenly with panko breadcrumbs, pressing gently so the crumbs adhere well.

Step 6: Fry

Heat vegetable oil to 170–175°C (340–350°F).

Carefully fry 2–3 croquettes at a time for about 3–4 minutes, turning once, until both sides are golden brown and crispy.

Transfer to a wire rack or paper towels to drain excess oil.

Frequently Asked Questions

Why are my croquettes falling apart?

The potato mixture may be too wet or too warm. Allow it to cool completely and ensure the potatoes are well drained before mashing.

Can I bake instead of fry?

Yes. Brush the breaded croquettes lightly with oil and bake at 200°C (400°F) for 20–25 minutes, flipping halfway through. An air fryer also works well for a crisp finish.

What potatoes work best?

Starchy potatoes like Russet or Yukon Gold create a light, fluffy filling and hold their shape well.

Can I make them ahead of time?

Absolutely. Shape and bread the croquettes, then refrigerate for up to 24 hours before frying or freeze them for longer storage.

What sauce goes best with Korokke?

Traditional tonkatsu sauce is the classic choice, but Japanese mayonnaise, Worcestershire sauce, or curry sauce are also delicious options.
