Japanese Cheese Croquette, known as Cheese Korokke (チーズコロッケ), is a delicious fusion of crispy golden panko breadcrumbs and a rich, gooey cheese-filled center. A popular variation of the traditional Japanese korokke, this dish combines creamy mashed potatoes with melted cheese or features cheese as the star ingredient, creating an irresistible snack, appetizer, or side dish.

Commonly found in Japanese cafés, bakeries, bento shops, and home kitchens, Cheese Croquettes are loved for their crunchy exterior, soft interior, and stretchy melted cheese that makes every bite satisfying.


What Is Japanese Cheese Croquette?

Cheese Korokke is typically made by combining seasoned mashed potatoes with cheese cubes or shredded cheese, shaping the mixture into patties, coating it in flour, egg, and Japanese panko breadcrumbs, then deep-frying until perfectly crisp and golden.

The result is a croquette with a crispy shell, fluffy potato filling, and a warm, melted cheese center.

Step 1: Cook the Potatoes

Boil the potatoes in salted water for 15–20 minutes, or until fork-tender.

Drain well and allow excess moisture to evaporate.

Mash until smooth.


Step 2: Prepare the Filling

Heat vegetable oil in a frying pan.

Sauté the chopped onion until soft and translucent.

Add the cooked onion to the mashed potatoes.

Mix in:

  • Butter
  • Milk
  • Salt
  • Black pepper
  • Parsley
  • Grated cheddar cheese

Allow the mixture to cool slightly.


Step 3: Shape the Croquettes

Take a portion of the potato mixture.

Flatten it in your palm.

Place a cube of mozzarella in the center.

Seal completely and shape into:

  • Oval croquettes
  • Round patties

Repeat with the remaining mixture.


Step 4: Bread the Croquettes

Coat each croquette with:

  1. Flour
  2. Beaten egg
  3. Japanese panko breadcrumbs

Press the breadcrumbs gently to ensure an even coating.


Step 5: Fry

Heat the oil to 170°C (340°F).

Fry the croquettes in batches for 3–4 minutes, turning occasionally until evenly golden brown and crispy.

Drain on a wire rack or paper towels.

Tips for Perfect Cheese Croquettes

  • Use starchy potatoes like Russet or Yukon Gold for a fluffy texture.
  • Let the potato mixture cool before shaping.
  • Seal the cheese completely to prevent it from leaking during frying.
  • Use fresh Japanese panko breadcrumbs for maximum crunch.
  • Fry at a steady temperature to achieve even browning.
  • Chill the shaped croquettes for 20–30 minutes before frying to help them hold their shape.
