Tonkatsu is a breaded, deep fried pork cutlet that became a staple of Japanese home and restaurant cooking after pork was popularized in Japan during the Meiji era. It's made by pounding a pork loin or cutlet thin, coating it in flour, egg, and panko breadcrumbs, then frying it until the crust is golden and shatteringly crisp.
The dish traces back to yoshoku, the category of Western influenced Japanese cooking that emerged in the late 1800s when Japan opened to European and American food ideas. Tonkatsu took the French technique of breading and frying (cotelette) and adapted it with panko, a coarser, airier breadcrumb than European styles use, which is part of why the crust turns out so light.
Today it's served everywhere from convenience stores to specialty tonkatsu restaurants, usually sliced into strips over shredded cabbage with rice, miso soup, and a tangy tonkatsu sauce.
What Actually Matters
The one step that separates good tonkatsu from great tonkatsu is the double fry, or at minimum, resting the cutlet on a wire rack immediately after frying instead of a paper towel lined plate. A paper towel traps steam against the crust and turns it soggy within minutes. A wire rack lets steam escape from all sides, so the panko stays crisp long enough to plate and serve. The other detail that matters just as much is oil temperature: fry too hot and the crust burns before the pork cooks through, fry too cool and the meat soaks up oil and turns greasy instead of crisp.
Tonkatsu Recipe
Serves 4 | Prep time: 20 minutes | Cook time: 15 minutes | Total time: 35 minutes
Ingredients
- 4 boneless pork loin cutlets (about 5 ounces each), trimmed
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 cup all purpose flour
- 2 large eggs, beaten
- 1 1/2 cups panko breadcrumbs
- 3 cups neutral oil (such as vegetable or canola), for frying
- 4 cups shredded green cabbage, for serving
- 1/2 cup tonkatsu sauce, store bought or homemade
- 4 cups cooked short grain rice, for serving
Method
- Pat the pork cutlets dry. Using the back of a knife or a meat mallet, pound each cutlet to an even 1/2 inch thickness. Season both sides with salt and pepper.
- Set up a breading station: flour in one shallow dish, beaten eggs in a second, panko in a third.
- Dredge each cutlet in flour, shaking off the excess, then dip in egg, then press firmly into the panko so it coats both sides evenly.
- Heat the oil in a heavy pot or deep skillet to 340 degrees F.
- Fry the cutlets two at a time for 3 to 4 minutes per side, until deep golden brown and the internal temperature reaches 145 degrees F.
- Transfer immediately to a wire rack set over a baking sheet. Let rest 2 to 3 minutes before slicing.
- Slice each cutlet into 1 inch strips. Serve over shredded cabbage with rice and tonkatsu sauce on the side.

Tips, Variations, and Storage
Chicken katsu works with this exact method, just extend the fry time slightly since chicken thighs run thicker. If you want to make this ahead, bread the cutlets and refrigerate them uncooked for up to four hours before frying, they'll hold their coating better than if you rest the fried cutlets and reheat. Leftover tonkatsu keeps for two days in the fridge and reheats best in an oven or air fryer at 375 degrees F for about eight minutes, never a microwave, which turns the crust rubbery.
Frequently Asked Questions
Can I use pork tenderloin instead of loin?
Yes, tenderloin works and is even more tender, but it's leaner, so watch the cook time closely to avoid drying it out.
Why did my breading fall off during frying?
Usually the pork wasn't dry enough before flouring, or the panko wasn't pressed on firmly. Pat the meat completely dry and press the crumbs on with your palm, not just a light dredge.
What oil is best for frying tonkatsu?
A neutral, high smoke point oil like vegetable, canola, or peanut oil. Avoid olive oil, its flavor and lower smoke point don't suit this dish.
Is tonkatsu the same as schnitzel?
They're cousins, not the same dish. Both are breaded and fried cutlets, but tonkatsu uses panko for a lighter, craggier crust and is almost always served with rice, cabbage, and a distinct fruit and vegetable based sauce.
Can I bake tonkatsu instead of frying it?
You can get close with a very hot oven and a wire rack, around 425 degrees F for 20 to 25 minutes, but you won't get quite the same crisp shell that deep frying gives you.
