• 1 1/8 cups (270 ml) water

For the Pork Cutlet (Tonkatsu)

• 2 boneless pork loin chops, about 6 oz (170 g) each, 3/4 inch thick (pound to 1/2 inch)
• 1/2 tsp kosher salt
• 1/4 tsp ground white or black pepper
• 1/2 cup (65 g) all-purpose flour
• 1 large egg + 1 tbsp water (for egg wash)
• 1 cup (50 g) panko breadcrumbs
• Neutral oil (canola, peanut, or rice bran) for frying—enough for 1/2 inch (about 2 cups/480 ml)

For the Onion–Dashi Sauce

• 1 cup (240 ml) dashi (homemade or from powder per package directions)

Step-by-Step Instructions

Step 1: Rinse and cook the rice

Place the rice in a bowl and rinse under cold water, swishing with your hand, draining and repeating until the water runs mostly clear (3–4 changes). Drain well. Combine with 1 1/8 cups water in a rice cooker or small saucepan. If stovetop: bring to a gentle simmer, cover, reduce heat to low, and cook 12 minutes. Turn off heat and rest, covered, 10 minutes. Fluff and keep warm.

Step 2: Pound and season the pork

Trim excess fat if desired. Place each chop between sheets of plastic or parchment and gently pound to an even 1/2 inch thickness—this helps tenderize and ensures even frying. Season both sides with the salt and pepper.

Step 3: Bread the pork in panko

Set up a breading station: one shallow dish with flour; one with the beaten egg plus 1 tbsp water; one with panko. Dredge pork in flour (shake off excess), dip in egg (let excess drip), then press firmly into panko until fully coated. Transfer to a wire rack and rest 5 minutes to help the coating adhere.

Step 4: Fry to golden and crisp

Pour oil into a 10–12 inch skillet to 1/2 inch depth and heat to 350°F/175°C. If you don’t have a thermometer, a panko crumb should sizzle immediately and brown in about 60 seconds. Fry pork 2–3 minutes per side until deep golden and cooked to an internal temperature of 145°F/63°C. Transfer to a wire rack to drain and rest 5 minutes. For extra-crisp, keep warm in a 200°F/95°C oven while you make the sauce.

Step 5: Simmer the onions in sweet-savory dashi

In a separate 10-inch skillet, combine dashi, soy sauce, mirin, sake, and sugar. Add the sliced onion and bring to a simmer over medium heat. Cook 4–5 minutes, stirring occasionally, until the onions turn translucent and tender and the sauce is lightly reduced but still brothy.

Step 6: Slice the cutlet and softly set the eggs

Slice the tonkatsu into 3/4-inch strips. Nestle the slices over the simmering onions. Lightly beat the 4 eggs just until the yolks are broken and streaky—do not overbeat. Pour the eggs evenly around and slightly over the pork. Sprinkle half the scallions on top. Cover and cook 60–90 seconds over medium heat until the eggs are just set around the edges with a glossy, custardy center. Cook a touch longer if you prefer firmer eggs.

Step 7: Assemble the donburi

Divide hot rice between two deep bowls. Slide the pork–onion–egg mixture and sauce over the rice. Shower with remaining scallions and a pinch of shichimi togarashi if you like a little heat. Serve immediately while everything is hot and saucy.

Pro Tips

• Keep it crisp: Rest fried cutlets on a wire rack, not paper towels, to prevent sogginess.
• Soft, silky egg: Lightly beat the eggs and cook covered—pull it off the heat while the center is still glossy.
• Right oil temp: 350°F/175°C is the sweet spot. Too cool = greasy; too hot = dark outside, undercooked inside.
• Pan size matters: A 10-inch skillet gives a nice shallow layer of sauce, which sets the eggs gently and evenly.
• Rice texture: Rinse rice well and let it rest after cooking for plump, separate grains that soak up the sauce.

Variations

• Chicken Katsudon: Substitute boneless, skinless chicken thighs or breasts, pounded to 1/2 inch and fried as directed.
• Vegetarian “Katsu”: Use firm tofu slabs or king oyster mushroom steaks; bread and fry the same way.
• Extra-Saucy: Increase dashi to 1 1/2 cups and soy to 4 tbsp for a more broth-forward bowl.

Storage & Make-Ahead

Katsudon is best served immediately, as the cutlet softens once it meets the sauce and egg. Make-ahead: Breaded, uncooked cutlets can be refrigerated up to 24 hours or frozen up to 1 month (separate with parchment). Fry straight from chilled; if frozen, fry a little longer over slightly lower heat to ensure the center cooks through. The onion–dashi sauce can be made 2 days ahead and refrigerated; rewarm to a simmer before adding the cutlet and eggs. Leftovers (assembled) keep 1 day in the fridge; reheat gently, covered, over low heat—it will be tasty but less crisp.
