Japanese Crab Croquette, known as Kani Korokke (カニクリームコロッケ), is a beloved yoshoku (Japanese Western-style) dish featuring a creamy crab-filled béchamel center coated in crispy golden panko breadcrumbs. The contrast between the crunchy exterior and the rich, velvety crab filling makes it one of Japan's most popular comfort foods. Found in restaurants, bakeries, bento shops, and home kitchens, these croquettes are often served with shredded cabbage, lemon wedges, and tangy tonkatsu sauce.

Perfect as an appetizer, side dish, or main course, Crab Croquettes combine delicate seafood flavor with luxurious creaminess in every bite.

What Is Japanese Crab Croquette?

Unlike potato croquettes, Kani Cream Korokke uses a thick white sauce (béchamel) mixed with crab meat instead of mashed potatoes. The chilled filling is shaped into patties, breaded with flour, egg, and panko, then deep-fried until beautifully crisp.

The result is a creamy interior bursting with sweet crab flavor wrapped inside an irresistibly crunchy shell.

Step 1: Cook the Onion

Melt butter in a saucepan over medium heat.

Cook the minced onion until soft and translucent without browning.

Step 2: Make the Béchamel Sauce

Add flour to the butter.

Cook for about 2 minutes while stirring constantly.

Gradually whisk in warm milk.

Continue whisking until the sauce becomes smooth and thick.

Season with:

  • Salt
  • White pepper
  • Nutmeg

Step 3: Add the Crab

Fold in:

  • Crab meat
  • Chopped parsley

Mix gently to avoid breaking the crab into tiny pieces.

Cook another minute.

Step 4: Chill the Filling

Transfer the mixture onto a tray.

Spread evenly.

Cover with plastic wrap touching the surface.

Refrigerate for 3–4 hours until completely firm.

Step 5: Shape the Croquettes

Divide the chilled mixture into equal portions.

Shape into:

  • Small cylinders

Handle gently because the filling is soft.

Step 6: Bread the Croquettes

Coat each croquette with:

  1. Flour
  2. Egg
  3. Panko breadcrumbs

Press the breadcrumbs lightly so they stick well.

Step 7: Fry

Avoid overcrowding the fryer.

Tips for Perfect Crab Croquettes
