Crab & Mushroom Cream Croquette

This is a Japanese style croquette (Korokke,コロッケ). In Japan there are a lot of different flavours, typically they use mashed potato or a cream sauce mixed with meat or vegetables and covered with panko (bread crumbs) and then fried. It is also very popular as a side dish. You can buy them freshly fried in supermarkets or some ready meal shops, also they make korokke at home too.

The first time I had Cream Croquette was in Japan. I loved it! The outside was very crunchy and inside very creamy. Even now I still remember the flavour. In this recipe I use white sauce to make it creamy and I also add cheese to make a richer flavour.

How to eat and which sauce to use

Korokke is a side dish in Japan. The Japanese people like to eat it with rice and some sliced cabbage or salad. Also udon, soba, curry rice or sandwich. Typically they would eat with Worcester sauce, tomato ketchup or soy sauce.

About the ingredients

The crab I used is sashimi snow crab which has already been cooked. I bought it in my local Asian supermarket. If you cannot find those, you can just use seafood sticks. If you don’t like seafood then you can just use ham.


In Japan some people use pizza cheese, however I used Mild Cheddar. The cheese is already quite salty so you do not need to add to much additional salt.

Crab & Mushroom Cream Croquette

This Crab & Mushroom Cream Croquette has a fantastic full flavour and is lovely and crunchy on the outside. I have used flour, butter and milk to make a very creamy white sauce. To give it the extra crunch I dipped into egg and Panko twice.

  • Add the oil to the pan and turn to a medium heat until around 170C. Drop a few pieces of Panko into the oil and if it forms little bubbles around the edge it is ready fry. This is shallow frying, but also you can deep fry. Once the colour has turned to golden brown it is cooked and ready to plate. You may want to drain some oil by using a sieve or kitchen roll.

  • When you fry it, you need to be careful because it is easy to burn.
  • If you use fine Panko it will make the outside more beautiful.
