Ingredients

• For the Tonkatsu
• Pork: 4 boneless pork loin chops, ¾–1 inch thick (about 6-8 oz each)
• Salt + Pepper: To taste
• Flour: ½ cup all-purpose flour
• Egg: 2 large eggs, whisked with 1 teaspoon neutral oil
• Neutral Oil for Frying: 4-6 cups (like canola, vegetable, or grapeseed)
• Panko: 2 cups Japanese panko breadcrumbs (look for large, airy flakes for the best crunch)
• For the Tonkatsu Sauce (Optional but Recommended)
• Worcestershire Sauce: ¼ cup
• Ketchup: ¼ cup
• Soy Sauce: 1 tablespoon
• Sugar: 1 teaspoon (or to taste)
• Optional Flavor Direction (Choose one):
• 1 tablespoon finely grated apple
• 1 teaspoon toasted sesame seeds, lightly crushed
• For Serving (Optional)
• Shredded Cabbage: Half a head, finely shredded
• Lemon Wedges: 1-2 lemons, cut into wedges
• Steamed Rice: For a complete meal

Directions

1. Prep the Pork:
   1. If your pork has a thick layer of fat on the edge, trim most of it off, leaving just a thin ribbon.
   2. Along the edges of each cutlet, make 3-4 shallow slits in any connective tissue (the thin membrane). This prevents the pork from curling up when frying.
   3. Place each cutlet between two sheets of plastic wrap. Using a meat mallet or the bottom of a heavy pan, gently pound the pork to an even ¾-inch thickness. This ensures even cooking.
   4. Season both sides of the pounded pork liberally with salt and pepper.
2. Set Up Breading Station:
   1. Prepare three shallow dishes or plates.
   2. In the first, add the all-purpose flour.
   3. In the second, whisk the eggs with 1 teaspoon of neutral oil. The oil helps the egg coat the pork more evenly and boosts adhesion.
   4. In the third, spread out the panko breadcrumbs.
3. Bread the Cutlets:
   1. Working one cutlet at a time, first dredge it in the flour, shaking off any excess. Make sure it's lightly coated everywhere.
   2. Next, dip the floured cutlet into the egg wash, allowing any excess to drip off.
   3. Finally, place the cutlet into the panko. Press the panko firmly onto both sides of the pork, ensuring it's completely covered. Don't be shy – pressing firmly helps the panko adhere and creates a thicker, crispier crust. Set aside on a clean plate.
4. Heat the Oil:
   1. Pour 4-6 cups of neutral oil into a heavy-bottom pot or deep skillet, enough to submerge the cutlets about halfway.
   2. Heat the oil over medium-high heat until it reaches 325-340°F (160-170°C). An instant-read thermometer is your best friend here!
   3. No thermometer? Drop a small pinch of panko into the hot oil. If it immediately sizzles gently and turns golden in about 30 seconds, your oil is ready. If it browns too fast, the oil is too hot; if it sinks and barely sizzles, it's not hot enough.
5. Fry:
   1. Carefully lower 1-2 tonkatsu cutlets into the hot oil, depending on the size of your pot (don't overcrowd!). Overcrowding will drop the oil temperature and lead to greasy katsu.
   2. Fry for 2-3 minutes per side, or until deeply golden brown and cooked through. For the crispiest crust, avoid touching or moving the cutlet for the first 30 seconds of frying.
   3. Maintain a steady oil temperature throughout frying, adjusting the heat as needed.
6. Drain + Rest:
   1. Once golden and cooked, carefully remove the tonkatsu from the oil.
   2. Place it on a wire rack set over a baking sheet. This allows air to circulate, keeping the crust crispy. Avoid paper towels, which can steam the bottom and make it soggy.
   3. Let the tonkatsu rest for 2-3 minutes.
7. Optional Quick Crisp Boost:
   1. If your tonkatsu isn't quite as crispy as you'd like after resting, you can briefly return it to the hot oil for 15-30 seconds, just until extra golden and crisp. This is a quick finishing step, not a second full fry.
8. Slice + Serve:
   1. Once rested, slice each tonkatsu cutlet into ¾-inch wide strips.
   2. Arrange on plates with a generous mound of finely shredded cabbage and a lemon wedge. Serve the tonkatsu sauce on the side for dipping.
9. Tonkatsu Sauce Step-by-Step InstructionsThis quick homemade sauce is the perfect tangy, sweet, and savory companion for your crispy tonkatsu.
10. Mix the Base: In a small bowl, whisk together the Worcestershire sauce, ketchup, soy sauce, and sugar until well combined.
11. Taste and Adjust: Taste the sauce and adjust the sugar to your preference. You might like it a little sweeter or tangier.
12. Add Optional Flavor:
    1. If using grated apple: Stir in the finely grated apple.
    2. If using toasted sesame seeds: Lightly crush the toasted sesame seeds with a mortar and pestle or the back of a spoon to release their aroma, then stir them into the sauce.
    1. Serve alongside your freshly fried tonkatsu.
