Retro Ham Katsu Recipe: Crispy Japanese Fried Ham Cutlets

What is Ham Katsu?

Ham Katsu is a classic Japanese dish made by breading and deep-frying slices of ham. It’s a nostalgic favorite that once reigned as a popular side dish in Japanese households and butcher shops. The combination of the salty ham and the crispy, golden-brown batter is simply irresistible—it pairs perfectly with steamed rice or a cold glass of beer.

While the traditional “retro” style uses thin pressed ham, a more modern “gorgeous” version using 1cm-thick loin ham or ham sandwiched with melting cheese is also trending. Whatever your preference, it’s best enjoyed fresh and hot with a generous drizzle of Worcestershire sauce!

Nutritionist’s Note📒: How is Ham Classified?

In Japan, the definition of “ham” has evolved over time:

Pressed Ham: Dominant in Japan until the 1970s. It’s a processed product made by kneading pieces of pork, beef, or even mutton with binders like starch and spices. It has a unique, firm texture that defines “old-fashioned” Ham Katsu.
Aged Ham (JAS Standard): This category includes the now-mainstream Loin Ham, as well as Shoulder Ham and Boneless Ham. These are made from high-quality whole cuts of meat.

Ingredients (Serves 3); Ham Katsu

Ham: 90g (6 slices of loin ham or pressed ham)
Breading Station:
- Wheat flour: 25g
- Egg: 50g (1 large egg)
- Water: 30g
- Bread crumbs (Panko): 40g
Cooking Oil: Moderate amount for frying

Ham Katsu Cooking Instructions

Prep the Ham: Stack 2 slices of ham together for each cutlet (making 3 thick cutlets total).
Make the Batter: In a bowl, mix the flour and water, then whisk in the beaten egg until smooth.
Coat: Dip each ham stack into the batter, then press into the bread crumbs. Pro Tip: Lay bread crumbs on a tray, place the ham on top, and cover thoroughly. Press lightly so the crumbs adhere firmly.
The Secret Step: Let the breaded ham rest in the refrigerator for 20 minutes. This prevents the batter from peeling off during frying!
Fry: Heat oil to 170°C (340°F). Fry the ham until it turns a beautiful golden brown.
Serve: Drain excess oil and serve immediately while crispy.
