Crispy and Tender Pork Tenderloin Cutlets (Hirekatsu, ヒレカツ)

“That perfect crunch, the tender bite—pure joy in every mouthful.”

This Hirekatsu (Japanese pork tenderloin cutlet) recipe delivers exactly that: a crisp, light coating that clings beautifully to the meat with a juicy interior so tender it almost melts. You’ll hear the satisfying “crunch” when you cut into it and feel the “crisp snap” with every bite—a hallmark of truly well-made tonkatsu.

While it may not rival a Michelin-starred tonkatsu restaurant, this home-style version earns full marks for its balance of technique, simplicity, and flavor.

The secret lies in tenderizing the meat thoroughly, sealing in moisture with mayonnaise, and mastering a two-stage frying method for perfect crispness.

Crispy and Tender Pork Tenderloin Cutlets (Hirekatsu)

Prep time: 15 minutes | Servings: 3

INGREDIENTS

1 pork tenderloin (whole)

1.5 tsp seasoned salt and pepper (Lawry’s or similar)

1 tbsp Japanese mayonnaise

1.5 cups panko breadcrumbs (adjust for coating)

vegetable oil (for deep frying)

(A) 1 egg

(A) 1 tbsp sake

(A) 1 tbsp water

(A) 4 tbsp all-purpose flour

1. Prepare the meat: Pound the pork tenderloin well with a rolling pin or meat mallet, then slice into ¾-inch-thick pieces (1.5–2 cm).

2. Season: Sprinkle with seasoned salt and pepper, then rub in mayonnaise to help keep the meat moist and tender.

3. Coat: Spread half the panko breadcrumbs on a tray. In a bowl, mix A (egg, sake, water, and flour) to make a batter and dredge each tenderloin in the batter. Place on the tray with panko and sprinkle the remaining breadcrumbs over the top. Use dry hands to gently press the crumbs onto all sides.

4. First fry: Heat oil to 300–320°F (150–160°C). Fry for about 3½ minutes, until the cutlet turns pale golden brown and floats slightly. Remove and let rest for 3 minutes.

5. Second fry: Increase oil temperature to 355°F (180°C) and fry again for about 30 seconds, until deep golden and crisp. Bubbles will become finer and the frying sound will be higher-pitched when the pork is done.

6. Lift the cutlet so just the edge touches the oil surface for a few seconds—this helps oil drain cleanly due to surface tension.

7. Drain: For best results, let the cutlet stand vertically on a rack to drain excess oil.

Tips & Notes

・Cutting the meat:

For smaller pieces, slice straight across.

For larger, thinner pieces, slice diagonally at a 45°angle.

・Choosing panko:

Coarse panko → crunchier, thicker crust (use about 2½ cups).

Fine panko → lighter, thinner coating (about 1½ cups).

・Frying technique:

Ensure that the pan is filled with enough oil so the cutlets can “swim” freely.

Don’t over-fry—the meat continues to cook with residual heat.

・Serving ideas:

Serve with lemon wedges, cabbage, and Japanese Worcestershire sauce, or turn leftovers into katsu sandwiches or katsudon (pork cutlet rice bowl).
