Creamy Korokke Recipe

Boil and mash potatoes

Place peeled and chunked potatoes in a large pot and cover with cold water by 1 inch. Add a pinch of salt. Bring to a boil over high heat, then reduce to a simmer and cook until fork-tender, about 15–20 minutes. Drain thoroughly and return potatoes to the hot pot for 1–2 minutes to dry out excess moisture.

Mash and season

Mash potatoes until mostly smooth (a few small lumps are okay). Add 3 tbs unsalted butter, 120 ml whole milk, 1.5 tsp salt, 1/2 tsp black pepper and 1/4 tsp sugar. Mix until creamy and set aside to cool slightly while you prepare the creamy béchamel mix.

Make roux

In a medium saucepan over medium heat, melt 3 tbs butter. Add 3 tbs all-purpose flour and whisk continuously for 1–2 minutes until the raw flour smell is gone and the roux is pale and bubbly but not browned.

Finish cream base

Slowly whisk in 240 ml whole milk and 60 ml heavy cream in a steady stream to avoid lumps. Continue cooking and whisking until the mixture thickens to a thick, creamy consistency (coat the back of a spoon), about 4–6 minutes. Stir in 1/2 tsp salt, 1/4 tsp white pepper and 1/2 cup finely chopped cooked onion if using. Remove from heat and let cool slightly.

Combine with potatoes

Fold the warm béchamel into the mashed potatoes gradually until fully combined and smooth but still spoonable. Taste and adjust seasoning. The final filling should be soft and creamy but firm enough to shape; if too loose, chill in the fridge 20–30 minutes to firm up.

Portion and shape

Divide the filling into 8 equal portions (about 125 g each). Wet your hands lightly to prevent sticking. Shape each portion into an oval or round patty about 2 cm thick, compacting gently so it holds its shape. Place shaped korokke on a lined tray and chill in the refrigerator for at least 20 minutes to firm (this helps them hold together when frying).

Prepare coating stations

Arrange three shallow dishes: one with 1 cup all-purpose flour (season with a pinch of salt), one with the 2 beaten eggs, and one with 2 cups panko breadcrumbs mixed with 3 tbs furikake. Lightly press the furikake into the panko so it adheres.

Bread the korokke

Working with chilled patties, dredge each patty in flour, shaking off excess. Dip into beaten egg, letting excess drip off, then press into the furikake-panko mixture to coat completely. For a thicker crust, double-dip: back into egg and panko again. Place coated korokke on a tray and chill 10 minutes to set the coating.

Heat oil

Pour neutral oil into a deep, heavy pot or deep fryer to a depth of at least 5–6 cm. Heat oil to 170–175°C (340–350°F). Use a thermometer for accuracy. If you don't have a thermometer, test with a small breadcrumb—the oil should sizzle steadily without smoking.

Fry korokke

Fry korokke in batches (do not overcrowd) for 3–4 minutes, turning once, until golden brown and crisp. Adjust heat as needed to maintain 170–175°C. Use a slotted spoon or spider to transfer fried korokke to a wire rack set over a tray or paper towels to drain excess oil.

Serve

Sprinkle chopped parsley or mitsuba over the korokke if using and serve immediately with lemon wedges and your choice of condiments (tonkatsu sauce, kewpie mayo or plain ketchup). Korokke are best eaten hot and crisp.
