Tonkatsu (豚カツ) — Crisp Japanese Pork Cutlet

• 4boneless pork loin cutlets (each 140 g and 1.5 cm thick)
• 6 gfine sea salt
• ½ tspground white pepper
• 2⅛ ozall-purpose flour
• 2eggs
• 1 tbspcold water
• 4¼ ozfresh panko breadcrumbs
• 3.8 cupneutral frying oil (rice bran, canola, or sunflower oil)
• 10.5 ozgreen cabbage (very thinly shredded)
• 1lemon (cut into 4 wedges)
• ½ cupJapanese tonkatsu sauce
• 4 tspkarashi mustard (optional but traditional)

Instructions

1. 1

   Pat the pork cutlets completely dry with paper towels, then make 4 shallow cuts through the fat cap on each cutlet to prevent curling during frying. Lightly pound each cutlet to an even 1.2 cm thickness, then reshape it with your hands so it remains compact.

2. 2

   Season both sides of the pork with the measured salt and white pepper, distributing the seasoning evenly across all 4 cutlets. Let the pork stand at room temperature for 10 minutes while you prepare the coating station, which helps the seasoning settle and reduces the chill before frying.

3. 3

   Place the flour in a shallow tray, beat the eggs with the cold water in a second tray, and spread the panko in a third tray. Keep one hand for dry ingredients and one hand for egg so the panko stays light and does not clump.

4. 4

   Dredge 1 cutlet in flour, pressing lightly so every surface is covered, then shake off excess flour until only a thin film remains. Dip it into the egg mixture, let excess drip back into the tray, then coat it generously in panko while pressing the crumbs onto the edges and faces.

5. 5

   Repeat the coating process with the remaining 3 cutlets, then rest the breaded pork on a wire rack for 8 minutes. This short rest hydrates the flour and egg layer, helping the panko adhere firmly instead of shedding into the oil.

6. 6

   Pour the oil into a heavy pot or deep skillet so it is at least 4 cm deep, then heat it to 170°C. Set a clean wire rack over a tray near the stove, because draining on a rack keeps the underside crisp better than draining on paper towels alone.

7. 7

   Fry 2 cutlets at a time for 3 minutes, turning once halfway through with tongs or chopsticks. Maintain the oil between 165°C and 175°C, because oil that is too cool makes the crust greasy while oil that is too hot browns the panko before the pork cooks through.

8. 8

   Transfer the fried cutlets to the wire rack and let them rest for 4 minutes while you fry the remaining cutlets. The pork should reach 63°C in the center after resting, and the crust should be evenly golden with visible coarse panko texture.

9. 9

   Slice each tonkatsu crosswise into 2 cm strips with a sharp knife, pressing straight down rather than sawing aggressively. Serve immediately with shredded cabbage, lemon wedges, tonkatsu sauce, and 1 tsp karashi mustard per serving if using.
