If you love Japanese food, you’ve probably heard of Tonkatsu — that perfectly golden, crunchy pork cutlet that’s juicy on the inside and crisp on the outside. It’s one of Japan’s most beloved comfort foods and is surprisingly easy to make at home. Whether you’re a beginner or a seasoned cook, this step-by-step guide will show you how to cook Tonkatsu perfectly every time.
What Is Tonkatsu?
Tonkatsu (とんかつ) is a Japanese dish made by coating a pork cutlet with panko breadcrumbs and deep-frying it until golden brown. “Ton” means pork, and “katsu” is short for “katsuretsu,” meaning cutlet. The result is a crunchy, flavorful dish often served with shredded cabbage, rice, and tangy Tonkatsu sauce.
It’s similar to European-style breaded cutlets like schnitzel, but Japanese Tonkatsu has its own unique twist — lighter, crispier coating, and a balance of savory and sweet flavors.

Step-by-Step Guide: How to Cook Tonkatsu Recipe
Step 1: Prepare the Pork Cutlets
- Choose the right cut: Pork loin or tenderloin works best for Tonkatsu. They’re tender and have just the right amount of fat for flavor.
- Trim and flatten: Trim excess fat if needed, then use a meat mallet to lightly pound each cutlet to an even thickness (about ½ inch). This ensures even cooking.
- Season: Sprinkle both sides with salt and pepper.
👉 Tip: Don’t over-pound the pork. A gentle flattening helps tenderize without breaking the meat fibers.
Step 2: Coat the Cutlets
We’ll use the classic three-step breading method — flour, egg, and panko.
- Flour: Dredge each cutlet lightly in flour, shaking off the excess. The flour helps the egg stick better.
- Egg wash: Dip into beaten eggs, coating evenly.
- Panko breadcrumbs: Press each cutlet into panko, ensuring full coverage. For extra crispiness, gently press the crumbs into the meat.
👉 Pro tip: Use panko instead of regular breadcrumbs. Panko gives Tonkatsu its signature crunch.
Step 3: Heat the Oil
- Pour vegetable oil into a deep pan until it’s about 1½ inches deep.
- Heat the oil to 170–175°C (340–350°F).
- To test the oil, drop a few panko crumbs in — if they float and sizzle immediately, the oil is ready.
Step 4: Fry the Tonkatsu
- Gently place the coated pork into the hot oil. Don’t overcrowd the pan — fry one or two at a time.
- Fry for 5–6 minutes per side, turning once, until golden brown and crispy.
- Once cooked, remove and place on a wire rack or paper towel to drain excess oil.
👉 Tip: Avoid flipping too often. Let it cook undisturbed to maintain the coating.
Step 5: Slice and Serve
Let the Tonkatsu rest for 2–3 minutes before slicing. Cut it into thick strips and serve it hot with:
- A drizzle (or side) of Tonkatsu sauce
- A mound of shredded cabbage
- A bowl of steamed rice
- A wedge of lemon
That’s it! You’ve just made authentic, restaurant-quality Tonkatsu at home.
How to Make Homemade Tonkatsu Sauce
If you can’t find bottled Tonkatsu sauce, here’s a quick DIY version:
Ingredients:
- 3 tbsp ketchup
- 1½ tbsp Worcestershire sauce
- 1 tbsp soy sauce
- 1 tsp sugar
- ½ tsp mustard (optional)
Instructions:
Mix all ingredients in a small bowl until smooth. Taste and adjust sweetness or saltiness to your liking. This sauce gives that perfect tangy, savory kick!
Tips for Perfect Tonkatsu
- Use panko breadcrumbs — not regular ones. They stay airy and crisp after frying.
- Maintain oil temperature — Too hot burns the crust; too cool makes it soggy.
- Don’t skip the resting step — It helps retain the pork’s juices.
- Use neutral oil — Vegetable, canola, or sunflower oil works best.
- Serve immediately — Tonkatsu is best when crispy and hot.
Popular Variations of Tonkatsu
- Chicken Katsu: Substitute pork with chicken breast for a lighter version.
- Miso Katsu: A Nagoya specialty topped with thick miso sauce.

- Cheese Katsu: Add melted cheese inside the pork cutlet for extra indulgence.
