Japanese potato croquettes, or korokke, are a delightful fusion of creamy mashed potatoes and savory ground beef. These crispy patties are a popular comfort food in Japan, often enjoyed as a snack or side dish. The golden brown exterior gives way to a soft, flavorful interior, making them a hit with both kids and adults alike.
Most of the ingredients for this recipe are common pantry staples. However, if you don't usually cook with ground beef, you might need to pick some up at the supermarket. Additionally, make sure you have enough breadcrumbs on hand, as they are essential for achieving the croquettes' signature crispy coating.

Potatoes: These form the base of the croquettes, providing a creamy texture.

Technique Tip for Making Perfect Croquettes

How To Store or Freeze Your Croquettes
- Allow the croquettes to cool completely after frying. This prevents condensation, which can make them soggy.
- Place the cooled croquettes on a baking sheet lined with parchment paper, ensuring they do not touch each other. This step is crucial to prevent them from sticking together.
- Freeze the croquettes on the baking sheet for about 1-2 hours, or until they are solid. This initial freezing helps maintain their shape.
- Once frozen, transfer the croquettes to an airtight container or a resealable freezer bag. Label the container with the date to keep track of their freshness.
- When ready to enjoy, reheat the croquettes directly from the freezer. Preheat your oven to 375°F (190°C) and bake them for 15-20 minutes, or until heated through and crispy. Alternatively, you can re-fry them in hot oil for a few minutes until they are golden and crispy again.
- For short-term storage, place the croquettes in an airtight container and refrigerate for up to 3 days. Reheat in the oven at 350°F (175°C) for about 10 minutes, or until warmed through.
- To maintain the croquettes's crispy texture, avoid microwaving them, as this can make them soggy.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the croquettes on a baking sheet lined with parchment paper. Bake for 10-15 minutes until they are heated through and crispy on the outside.
Use an air fryer for a quick and efficient method. Set the air fryer to 350°F (175°C) and cook the croquettes for about 5-7 minutes. This will help retain their crispy texture.
If you prefer using a microwave, place the croquettes on a microwave-safe plate. Cover them with a damp paper towel to prevent drying out. Heat on medium power for 1-2 minutes, checking halfway through to ensure they are evenly heated.
For a stovetop method, heat a small amount of oil in a skillet over medium heat. Place the croquettes in the skillet and cook for 3-4 minutes on each side until they are warmed through and crispy.
If you have a toaster oven, preheat it to 350°F (175°C). Place the croquettes on the toaster oven tray and heat for 10-12 minutes, turning them halfway through to ensure even reheating.
