Sauce katsudon is a Japanese rice bowl dish featuring a crispy deep-fried pork cutlet (tonkatsu) simmered briefly in a savory-sweet sauce with onions and egg, then served over steamed rice. Unlike the classic katsudon, which uses dashi-based broth, this version relies on a thicker, Worcestershire-based sauce that clings to the cutlet, making it bold, tangy, and deeply satisfying. It’s a home-style adaptation that’s quicker and uses pantry-friendly ingredients.
Ingredients
- 2 boneless pork loin chops, about ¾ inch (2 cm) thick (12 oz / 340 g total)
- Salt and freshly ground black pepper
- All-purpose flour, for dusting (about ¼ cup / 30 g)
- 1 large egg, beaten (for breading)
- 1 cup (100 g) panko breadcrumbs
- Vegetable oil, for deep-frying (about 2 cups / 500 ml)
- 1 small onion, thinly sliced (about 4 oz / 115 g)
- 3 large eggs
- 2 cups (400 g) cooked Japanese short-grain rice, warm
- 2 tablespoons chopped scallions (green onions), for garnish
For the sauce:
- ½ cup (120 ml) Worcestershire sauce
- 3 tablespoons (45 ml) soy sauce
- 2 tablespoons (30 g) granulated sugar
- 1 tablespoon (15 ml) mirin (sweet rice wine)
- 1 teaspoon grated fresh ginger
Instructions
- Prepare the pork: Using a meat mallet or the back of a heavy knife, gently pound each pork chop to an even thickness of about ½ inch (1.3 cm). Season both sides with salt and pepper.
- Bread the pork: Place the flour in a shallow dish, the beaten egg in another, and the panko in a third. Dredge each chop in flour, shaking off excess, then dip in egg, and finally coat with panko, pressing gently to adhere. Set aside on a wire rack for 5 minutes to let the coating set.
- Make the sauce: In a small bowl, combine Worcestershire sauce, soy sauce, sugar, mirin, and grated ginger. Stir until the sugar dissolves. Set aside.
- Heat the oil: In a deep skillet or heavy pot, heat about 1 inch (2.5 cm) of vegetable oil to 350°F (175°C). If you don’t have a thermometer, test by dropping a breadcrumb into the oil—it should sizzle immediately.
- Fry the pork: Carefully place the breaded chops into the hot oil. Fry for 2–3 minutes per side, until golden brown and cooked through. The internal temperature should reach 145°F (63°C) (USDA FSIS safe minimum for whole cuts of pork) as checked with a food thermometer. Transfer to a wire rack to drain and rest for 3 minutes.
- Slice the cutlets: Once rested, slice each cutlet into ¾-inch (2 cm) wide strips.
- Simmer the sauce and onion: In a medium skillet or small saucepan, combine the prepared sauce and sliced onion. Bring to a simmer over medium heat and cook for 2–3 minutes, until the onion begins to soften.
- Add the pork: Place the sliced cutlet pieces into the simmering sauce, arranging them evenly. Let them warm through for about 1 minute.
- Add the eggs: Beat the 3 eggs in a bowl. Pour the beaten eggs evenly over the pork and sauce. Cover the pan and cook for 1–2 minutes, until the eggs are just set but still slightly runny (if you prefer them fully cooked, cook for an additional minute until firm).
- Assemble the bowls: Divide the warm rice between two bowls. Gently slide the egg-and-pork mixture over the rice, spooning any extra sauce on top. Garnish with chopped scallions. Serve immediately.
Tips
- Pork substitution: If pork loin is unavailable, use boneless pork chops or even chicken breast (adjust cooking time to 165°F / 74°C). For a leaner option, turkey cutlets work well.
- Panko alternative: If you don’t have panko, crush regular breadcrumbs or cornflakes for a similar crunch. The texture will be slightly different but still delicious.
- Don’t skip resting: Letting the breaded pork rest before frying helps the coating adhere better and prevents it from falling off during cooking.
- Adjust sweetness: The sauce is balanced between tangy and sweet. If you prefer less sweet, reduce sugar to 1½ tablespoons (22 g). For extra tang, add a teaspoon of rice vinegar.
Serving Suggestions
Serve sauce katsudon as a hearty main dish with a side of pickled vegetables (like takuan or cucumber) and a light miso soup. A simple green salad with a sesame dressing also complements the rich flavors. For a traditional touch, serve with a small bowl of Japanese tsukemono (pickles) and a cup of green tea.
Variations
- Chicken katsudon: Use boneless chicken thighs or breasts instead of pork. Cook until the chicken reaches 165°F (74°C).
- Vegetarian version: Replace pork with thick slices of firm tofu or eggplant, breaded and fried the same way. Skip the meat and use vegetable broth in the sauce if desired.
- Spicy sauce katsudon: Add 1 teaspoon of gochujang or sriracha to the sauce for a spicy kick.
- Cheese topping: For a fusion twist, sprinkle shredded mozzarella over the egg while it’s setting, then cover until melted.
Storage and Reheating
Store any leftover sauce katsudon in an airtight container in the refrigerator for up to 3 days. The rice and toppings will soften, but the flavor remains. To reheat, place in a microwave-safe dish and heat in 30-second intervals until hot, or reheat in a skillet over medium heat with a splash of water to prevent drying. For best texture, reheat only the pork and egg mixture and serve over fresh rice. Freezing is not recommended as the egg and rice become mushy.
Frequently Asked Questions
Can I use pre-made tonkatsu sauce instead of making my own?
Yes, you can use bottled tonkatsu sauce, but it’s thicker and sweeter. To mimic this recipe’s sauce, mix ½ cup (120 ml) tonkatsu sauce with 2 tablespoons soy sauce and 1 tablespoon mirin. Adjust sugar to taste.
What is the best rice to use?
Japanese short-grain or sushi rice is ideal because it’s sticky and holds up well under the sauce. If unavailable, use another short-grain rice like calrose. Long-grain rice will be less cohesive but still edible.
Can I make this without deep-frying?
Yes, you can pan-fry the breaded pork in a shallow layer of oil (about ¼ inch) over medium-high heat, turning once, until golden and cooked through. It won’t be as crispy but will still taste great.
How do I know when the eggs are done?
The eggs should be set but still soft and slightly custardy. If you prefer fully cooked eggs, cook until the eggs are completely firm, about 2–3 minutes more. Always ensure the dish is heated through to 165°F (74°C) if reheating leftovers.
Can I use pork tenderloin instead of loin chops?
Yes, pork tenderloin is lean and works well. Slice it into medallions and pound thin. Cook to 145°F (63°C) with a 3-minute rest.
What if I don’t have mirin?
Substitute with 1 tablespoon dry sherry or white wine mixed with ½ teaspoon sugar. Or simply use 1 tablespoon of water and increase the sugar by ½ teaspoon.
