What is Tonkatsu?
Tonkatsu (とんかつ) may seem simple at first glance. It’s just a Japanese pork cutlet breaded and fried to golden perfection, right? But achieving that perfect balance of crackling outside and juicy inside that you remember from Japan is surprisingly complex.
The authentic tonkatsu experience hinges on techniques passed down through generations in Japan since its creation around 1899. Originally inspired by French cuisine but adapted with distinctly Japanese tastes. It started with beef, but over time, it’s turned into this amazing pork cutlet that’s become one of Japan’s favorite comfort foods.
The term “ton” (豚) comes from the Japanese kanji character for “pig,” which is a common prefix in various pork-based dishes, like tonjiru (pork miso soup) and tonteki (pork chop steak). The suffix “katsu” sounds like the Japanese word for “cutlet.”
The cutlet itself can be used in many other dishes such as katsudon, katsu curry or katsu sando.
Traditionally, tonkatsu is complemented with a tangy tonkatsu sauce, served alongside fluffy rice, crisp shredded cabbage, and a bowl of miso soup. Beyond the classic pork version, the “katsu” technique has expanded to include:
- Chikinkatsu: A golden chicken cutlet.
- Gyuukatsu: A rich beef cutlet.
- Kushikatsu: Skewered deep-fried meat or vegetables.
- Miso katsu: A pork cutlet lavished with a unique red miso sauce.
In this guide, I’ll share all my knowledge behind each step of the process, explaining not just how to make tonkatsu.
Ingredients & Substitution Ideas
- Thick boneless pork chops (2-2.5cm/¾-1 inch thick): If you want to make a great tonkatsu, you’ve got to get the right cut. If you’re looking for something leaner, go for the loin or tenderloin with a thin layer of fat along one edge. Or, if you want something richer and meatier, try boneless ribs. Thick slices will give you that satisfying crunch-to-juicy-meat ratio.
- High-temperature neutral oil: Go for a neutral oil with a high smoke point (170-180°C/340-355°F) such as rice bran oil (my personal preference), canola, or refined sunflower.
- Batter & Coating: All-purpose flour, egg, and whole milk. Mixing the egg with the milk helps stretch the mixture and helps make the meat more tender.
- Panko breadcrumbs: The defining element that separates tonkatsu from regular cutlets. For the best crispy experience, try making your own panko—it’s easier than you might think! Japanese panko has a distinctive airy, flaky structure unlike other breadcrumbs. If you’re interested in learning more about panko, check out my post about making your own panko at home.
- Homemade sauce: Just blend Worcestershire sauce, tomato ketchup, soy sauce, light brown sugar, and white sesame seeds for a perfect balance of tangy, sweet, and umami flavors that complement the crispy pork perfectly.

Start by preparing your tonkatsu sauce, allowing the flavors to meld while you work on the pork. Add the Worcestershire sauce, ketchup, Japanese soy sauce, light brown sugar, and white sesame seeds to a small bowl and whisk until well combined. Set aside for later.
You can also try grinding some of your sesame seeds in a mortar and pestle, and leaving the rest whole. This will release more of the nutty oils and create a different texture.

Preheat your oil to 170°C (340°F). While you wait, make sure the pork cutlets are prepared properly to get the best texture and even cooking.
First, grab your cold pork straight from the fridge. Cold meat helps the coating stick better because the temperature difference affects how moisture escapes from the meat.
Using a sharp knife, make strategic incisions in the connective tissue between the fat and meat. Make shallow cuts about 1cm apart along the edge where the white fat meets the pink meat. Also, make 2-3 cuts into any visible muscle fibers running through the meat.
Fat and muscle contract at different rates when heated. If you don’t cut these parts, your tonkatsu is going to curl up when you fry it, and it’ll end up being cooked unevenly. Also, cutting the muscle fibers keeps the meat from getting tough and chewy when you cook it, since these fibers tighten up when heated.
Pat your pork dry with paper towels. This step is key because it gets rid of any surface moisture that could create steam during frying, which would mess up the coating.
Sprinkle both sides with a bit of salt and pepper, and then pound the meat with the flat side of a meat mallet, starting in the center and working out until it’s all even and about 2 cm (¾ inch) thick.
Just be careful not to pound the meat too thin. For tonkatsu, about 2cm is perfect. Thinner meat will cook too quickly and dry out, while thicker cuts won’t cook through properly at the same rate the coating becomes golden.
Prepare a “coating station” with three wide containers. Add flour to one and panko breadcrumbs to another. In the middle container, crack an egg and add a tablespoon of whole milk and a teaspoon of cooking oil. Whisk together until smooth but be careful not to overmix or create too many bubbles.
Adding oil to your egg mixture is a key step in my recipe. The oil creates a moisture barrier that prevents the coating from separating during frying and helps lock in the meat’s juices. The milk proteins further tenderize the meat and add richness to the flavor profile.
Place the pork in the flour and coat both sides thoroughly. This first layer of flour acts as a dry surface for the egg mixture to adhere to. Gently pat off any excess flour—too much will create a gummy layer between the meat and egg.
Then, put it in the egg mixture, making sure to coat both sides evenly. Let any extra liquid drip off for a few seconds. The egg is like the glue that’ll hold the final panko layer in place.
Lastly, add the panko breadcrumbs, pressing them gently but firmly into the surface. The pressure helps the breadcrumbs stick properly without squishing them too much, which would reduce their ability to create that signature airy crunch.
If you’re looking for that classic crispy texture, try “nama panko” (fresh panko). It’s got more moisture than the dried version. You can easily make it by just blitzing some fresh bread. For more details on how to make it and what kind of bread works best, check out my panko guide.
After coating the pork, let it rest for 15 seconds before frying. This brief resting period allows the three layers to bond properly and stabilize, significantly reducing the chance of the coating separating during cooking.
Make sure you’re using enough oil—the pork should float freely without touching the bottom of the pan. Rice bran oil is my go-to choice as it has a high smoke point and neutral flavor that won’t interfere with the delicate taste of the pork.
When the oil hits 170°C (340°F), carefully slide the coated pork into the oil. Now, here’s the most important rule: don’t touch the meat for at least 30 seconds! This lets the coating set properly and prevents it from separating from the meat.
You can tell the oil is around 170°C when you insert wooden chopsticks and observe small bubbles slowly forming at the tip—too many rapid bubbles means the oil is too hot, hardly any bubbles means it’s too cool.
When you first add it to the oil, it will crackle loudly. This is the reaction between the oil and the moisture in the meat. As it cooks, the crackling gets quieter, this is how you can tell if its cooked all the way through by sound.
Fry each side for approximately 4 minutes for a total of 8 minutes, or until the coating reaches a deep golden brown.
Once golden and cooked through, transfer the tonkatsu to a wire rack—never directly onto paper towels, which trap steam underneath and make the bottom coating soggy. Allow it to rest for 5 minutes before cutting, giving time for the juices to redistribute throughout the meat.
Use a sharp knife and cut the tonkatsu into strips about 2cm wide. The proper cutting technique is to press downward with a single, clean motion rather than sawing back and forth, which can tear the crispy coating.
Serve immediately with your homemade sauce and shredded cabbage!
Enjoy!

- Cold meat works best – Use pork straight from the refrigerator for better breading adhesion.
- Cut the connective tissue – Make small cuts 1cm apart where fat meets meat to prevent curling.
- Add oil to your egg mixture to create a moisture barrier that prevents coating separation.
- Let the breaded pork rest for 15 seconds before frying to stabilize the layers.
- Use enough oil so the cutlet floats freely without touching the bottom of the pan.
- Don’t touch the meat for at least 30 seconds after placing it in the oil – this allows the coating to set.
- Listen to the cooking sounds – loud crackling that gradually becomes quieter indicates proper cooking.
- Always drain on a wire rack, never on paper towels which trap steam and make the bottom soggy.
With these simple tips in mind, you’re set for success every time you make the best tonkatsu!
Troubleshooting and FAQ
One of the biggest problems you might face when making homemade tonkatsu is the crumb layer not sticking to the surface of the pork. Uneven and messy tonkatsu with gaps is my worst nightmare!
Let’s look at the potential causes and how to prevent them!
Meat, including tonkatsu, tends to shrink when heated, leading to gaps between the batter and meat, causing the batter to peel off. To prevent this, it’s essential to pound the pork chops before cooking. However, it’s crucial to start with thick pork cuts; pounding too thin results in a less desirable, floppy tonkatsu. Thus, using thick, pounded pork chops is key to ensuring the batter stays intact.
The batter for traditional tonkatsu consists of flour, eggs, and breadcrumbs, each vital to the dish’s integrity. Any inconsistency in one layer affects the subsequent ones. Inadequate coating can cause the batter to peel off over time. It’s essential to apply each layer generously but without overdoing it, striking a careful balance. Ensuring a firm and even battering for each layer is undoubtedly crucial.
Achieving the ideal golden crust for tonkatsu hinges on using plenty of oil and maintaining the right frying temperature. Too hot, and you risk burning the batter with undercooked pork. Too cool, and the outcome is a pale batter with dry, tough pork. To sidestep these pitfalls, opt for oils with high smoke points and maintain a frying temperature of 170°C (340°F).
Meal Prep & Storage
Tonkatsu offers several meal prep and storage options, but you’ll need specific techniques to maintain quality.
Meal Prep Options
- Raw Prep (Best Option): You can prepare the meat (trimming, making cuts in the connective tissue) up to 1 day ahead and store it tightly wrapped in the refrigerator. The tonkatsu sauce can be made up to 1 week ahead.
- Breaded Prep (Use Caution): While you can bread cutlets ahead of time, it’s not ideal as meat juices will seep out and make the breadcrumbs soggy. If you must bread ahead, freeze immediately after coating rather than refrigerating.
- Freezing Breaded Uncooked Cutlets: After breading, place cutlets on a metal tray for quick freezing, then wrap each piece individually in plastic wrap and store in an airtight freezer bag for up to 2 weeks.
For frozen breaded cutlets, cook directly from frozen without thawing. Start at a lower temperature (150°C/300°F) to cook the meat through completely, then finish at a higher temperature (170-180°C/340-360°F) to crisp the coating. Cooking at high heat the entire time will result in a burnt exterior and an undercooked interior.
Storage & Reheating
For cooked tonkatsu, allow it to cool completely before storing.
- Refrigerate for up to 2 days by placing on a plate lined with paper towels and covering with plastic wrap.
- For longer storage, freeze for up to 1 month by wrapping each cutlet individually in plastic wrap, then placing in an airtight freezer bag.
When reheating refrigerated tonkatsu, use a toaster oven or conventional oven to restore crispiness. For frozen tonkatsu, partially defrost in the microwave (without plastic wrap), then finish in a toaster oven, conventional oven, or air fryer.

Hello and thank you for the recipe! I wonder what is the purpose to put milk and oil to the egg mixture? Thank you 🙂
Hi, thank you for the rating!
I add milk because it’s said to help make the meat softer and more tender. Adding oil is a trick that restaurants use to help make the egg smoother so it coats the katsu more evenly and stops the panko falling off. Apparently it also makes a thin layer around the meat which keeps the flavour inside too. Hope that helps, thanks for your question! 🙂
Thank you! Somehow I don’t receive email notification of your reply, sorry.
I love your recipe, they are simple and some even give a different approach compared to other recipe.
