Tonkatsu is a classic Japanese dish of juicy pork cutlets coated in large-flake panko breadcrumbs and fried until deeply golden and crisp. Serve with a sweet-savory tonkatsu sauce, shredded cabbage, and steamed rice for a satisfying, restaurant-style meal. Below are tips and a step-by-step method to achieve a thick, crunchy panko crust that stays crisp and protects the pork so it stays tender inside.
If you want the best home-cooked tonkatsu, focus on the coating. The signature of great tonkatsu is a thick, audible crunch from large panko flakes. This recipe emphasizes a generous layer of panko so every bite has texture and the pork inside remains juicy.
What is Tonkatsu (豚カツ)?
Tonkatsu is breaded and deep-fried pork cutlets. Commonly made from boneless pork loin or pork chops, the meat is pounded to an even thickness, dredged in flour, dipped in egg wash, and coated in Japanese-style breadcrumbs called panko. Traditionally it is served with a thick, sweet-savory tonkatsu sauce, shredded cabbage, and white rice. Variations exist across East Asia; in Korea, a similar dish is known as donkatsu and may include fillings such as cheese.
Ingredients for Tonkatsu
- Boneless pork loin or pork chops – 2 slices, each about 5 oz, pounded to roughly 3/4 inch thick. A slightly thicker cut helps keep the pork juicy.
- Panko breadcrumbs – Use large-flake, unseasoned panko for a light, flaky, extra-crispy crust.
- All-purpose flour – For dredging so the egg wash adheres evenly.
- Egg – Beaten; mixing a tablespoon of flour into the beaten egg creates a thicker wash that helps panko stick better for a thicker coating.
- Salt and pepper – Season the meat before breading.
- Vegetable oil – Enough for deep frying; choose an oil with a high smoke point.
Panko Breadcrumbs
Panko are Japanese breadcrumbs made from crustless bread, producing larger, airier flakes than typical breadcrumbs. For tonkatsu, choose panko with large, thin slivers for maximum crunch. Unseasoned panko is ideal so you control the seasoning of the final dish.
Tonkatsu Sauce
A good tonkatsu sauce is sweet, tangy, and umami-rich—similar to a mild Japanese barbecue sauce. A quick and reliable version combines ketchup, Worcestershire sauce, and soy sauce. Optionally add a touch of sugar, garlic powder, or onion powder to adjust sweetness and depth to your taste. Stir together and set aside to serve with the fried cutlets.
- Ketchup – Provides body, sweetness, and tomato flavor.
- Worcestershire sauce – Adds savory, tangy depth and umami.
- Soy sauce – Gives saltiness and extra umami.
- Optional – Sugar, garlic powder, or onion powder to fine-tune flavor.
How to Make Tonkatsu
- Prepare the pork: Trim excess fat and cut small slits in the white connective tissue along the edge so the meat won’t curl while cooking. Pound the pork to an even thickness of about 3/4 inch. Season both sides with salt and pepper.
- Dredge in flour and egg: Place flour, beaten egg (mix in 1 tablespoon flour for a thicker wash if desired), and panko in separate bowls. Lightly coat the pork in flour, shake off excess, dip in the egg wash, and allow excess to drip off.
- Press in the panko: Firmly press each side of the pork into the panko, building a thick, even layer. Press again right before frying to cover any spots where the crumbs soaked into the egg and became damp.
- Heat the oil: In a deep pot or fryer, heat enough oil for deep frying to about 340°F (170°C). Medium heat is key so the pork cooks through without the breadcrumbs burning.
- Fry the cutlets: Gently lower the cutlets into the hot oil and fry 5–6 minutes per side until the panko is golden brown and the pork is cooked through. Maintain the oil temperature and avoid overcrowding—work in batches if necessary.
- Rest and slice: Drain on a rack or paper towel briefly, then slice into 1-inch strips for a restaurant-style presentation. Serve immediately with shredded cabbage, steamed rice, and tonkatsu sauce for dipping or drizzling.
Using a thick panko crust not only maximizes crunch but also insulates the meat so it stays tender and juicy. For best results, keep the oil temperature steady, press the panko firmly into the meat, and avoid overcrowding the fryer.
Slice tonkatsu into strips and serve with plenty of thinly shredded cabbage, rice, and miso soup for a complete meal. Drizzle or serve tonkatsu sauce on the side so diners can control how much they use. Enjoy while hot for the best texture.
Tonkatsu Tips
- Choose large-flake panko for the most authentic, airy crunch.
- Add 1 tablespoon of flour to the beaten egg to create a thicker wash that holds more panko and produces a thicker crust.
- Press the cutlet into the panko twice: once during breading and once more immediately before frying to replace any crumbs that have softened.
- Maintain oil around 340°F (170°C) for even cooking. If you don’t have a thermometer, drop a few breadcrumbs into the oil—when they sizzle and float, it’s close to ready.
- Avoid overcrowding the fryer; fry in batches to keep the oil temperature steady and the crust crisp.

Equipment
- Large heavy pot or deep fryer
- Fine-mesh skimmer or slotted spoon
Ingredients
- 2 slices boneless pork loin or pork chops, pounded to 3/4 inch thick (about 5 oz each)
- 1 cup Japanese panko breadcrumbs
- 1/2 cup all-purpose flour
- 1 egg, beaten (mix in 1 tablespoon flour for a thicker wash)
- Salt & pepper
- Vegetable oil for frying
Tonkatsu Sauce
- 4 tablespoons ketchup
- 2 1/2 tablespoons Worcestershire sauce
- 1 tablespoon soy sauce
- 1/8 teaspoon garlic and onion powder (optional)
- 1 1/2 teaspoons sugar (optional; adjust to taste)
Instructions
Make the Tonkatsu Sauce
Combine ketchup, Worcestershire sauce, soy sauce, and garlic and onion powder in a small bowl. Taste and add sugar if you prefer a sweeter sauce. Set aside.
Bread the Pork
Cut slits in the connective tissue on the outer edge of each piece to prevent curling. Flatten to about 3/4 inch thickness. Place flour, beaten egg, and panko in separate shallow bowls. Season pork with salt and pepper. Dredge in flour, dip in the egg wash (with added flour if using), then press firmly into the panko to form a thick, even coating. Press again just before frying to replace any crumbs that softened.
Deep-fry the Pork Cutlets
Heat oil in a large pot to about 340°F (170°C). If you don’t have a thermometer, test by dropping a few breadcrumbs into the oil—when they sizzle and float, the oil is hot. Fry each cutlet for 5–6 minutes per side until golden brown and cooked through. Use a skimmer to remove any loose crumbs and avoid overcrowding the pot. Drain on a rack briefly, then slice and serve with sauce, shredded cabbage, and rice.
Notes
- Panko selection: Choose large-flake, Japanese-style panko for the lightest, crunchiest texture.
- Extra crisp: Press the cutlets into the panko a second time immediately before frying to ensure full coverage and a thicker crust that helps keep the pork juicy.
- Oil temperature: Keep the oil steady around 340°F. Adjust the heat if the crust browns too quickly or too slowly. Fry in batches to maintain temperature.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days or freeze for up to 1 month. Reheat in a toaster oven or air fryer at 350°F until warm and crisp, about 4–7 minutes.
