Method: Korokke Recipe

Step 1: Prepare the Potatoes
Begin by placing the peeled and chunked russet potatoes in a large pot. Cover with water, add a pinch of salt, and bring to a boil. Cook the potatoes for about 15-20 minutes or until they are fork-tender. Drain and return to the pot.
Step 2: Mash the Potatoes
Add 1 tablespoon of unsalted butter, 1/4 teaspoon salt, and 1/8 teaspoon black pepper to the drained potatoes. Mash until smooth and creamy. Set aside to cool slightly.
Step 3: Cook the Beef Filling
In a skillet over medium heat, add 2 teaspoons of neutral oil. Once hot, add the finely chopped yellow onion. Sauté for about 3-4 minutes until the onion is translucent. Add the lean ground beef, breaking it apart with a spatula, and cook until browned. Season with the remaining 1/4 teaspoon salt and 1/8 teaspoon black pepper. Remove from heat and let it cool.
Step 4: Combine Filling
Once both the mashed potatoes and beef mixture are cool enough to handle, combine them in a mixing bowl. Mix thoroughly until well combined. This mixture will be the delicious filling for your korokke.
Step 5: Shape the Korokke
With clean hands, take a portion of the filling and shape it into oval or round patties, about 2-3 inches in diameter. Place them on a parchment-lined baking sheet.
Step 6: Prepare for Coating
Set up a breading station with three shallow bowls: one with all-purpose flour, one with beaten eggs, and one with panko breadcrumbs. Coat each potato patty first in flour, then dip in the beaten eggs, and finally coat with panko breadcrumbs. Make sure each patty is evenly coated for that perfect crunch.
Step 7: Fry the Korokke
In a deep fryer or a heavy pot, heat oil to 350°F (175°C), ensuring it is deep enough for frying (at least 2 inches). Carefully add the breaded korokke in batches, being mindful not to overcrowd the pot. Fry for 3-4 minutes on each side or until golden brown and crispy.
Step 8: Drain and Serve
Once cooked, use a slotted spoon to remove the korokke from the oil, placing them on paper towels to drain any excess oil. Serve warm with tonkatsu sauce drizzled on top or on the side for dipping.
Easy Ingredient Swaps

- Ground beef can be substituted with ground turkey or chicken for a lighter option.
- For a vegetarian version, use cooked lentils or mushrooms instead of meat.
- Use sweet potatoes instead of russet potatoes for a twist on flavor and color.
- Replace tonkatsu sauce with ketchup or a homemade barbecue sauce if desired.
Flavor Logic
The combination of creamy mashed potatoes and savory ground beef creates a comforting filling that is both satisfying and flavorful. The use of onions adds a subtle sweetness, while the panko breadcrumbs provide an irresistible crunch when fried. The tonkatsu sauce introduces a tangy element that complements the richness of the korokke, making each bite a delightful experience.
Storing, Freezing & Reheating
Korokke can be stored in an airtight container in the refrigerator for up to 3 days. To freeze, place the uncooked, breaded korokke in a single layer on a baking sheet and freeze until solid. Transfer to a freezer-safe bag for up to 3 months. To reheat, simply fry frozen korokke directly from the freezer until golden and crispy, or bake them in the oven at 375°F (190°C) until heated through.
Your Questions, Answered
Can I make korokke ahead of time?
Yes, you can prepare the filling and shape the korokke ahead of time. Store them in the refrigerator or freeze them for later frying.
What oil is best for frying korokke?
A neutral oil with a high smoke point, such as vegetable oil or canola oil, is ideal for frying korokke to achieve the perfect crispy texture.
Can I bake korokke instead of frying them?
Yes, you can bake korokke for a healthier option. Preheat the oven to 400°F (200°C), place the korokke on a baking sheet, and spray lightly with oil. Bake for about 20-25 minutes, flipping halfway through, until golden and crispy.
What can I serve with korokke?
Korokke is delicious on its own, but you can serve it with a side salad, steamed vegetables, or rice for a complete meal. Tonkatsu sauce is the perfect condiment to accompany korokke.
