Chicken katsudon is a beloved Japanese comfort food: a crispy panko-breaded chicken cutlet simmered in a savory-sweet dashi broth with onions and egg, then served over steaming rice. It’s a complete meal in one bowl, and the contrast between the crunchy cutlet, soft custardy egg, and tender rice makes it utterly satisfying. This recipe delivers that classic flavor at home with clear steps and realistic timings.
Ingredients
- 4 boneless, skinless chicken thighs (about 1.5 lb / 680 g total)
- Salt and freshly ground black pepper
- 1/2 cup (60 g) all-purpose flour
- 2 large eggs, beaten (for dredging)
- 1 1/2 cups (150 g) panko breadcrumbs
- Neutral oil (like canola or vegetable), for frying
- 1 cup (240 ml) dashi stock (or 1 cup water + 1 tsp dashi granules)
- 1/4 cup (60 ml) soy sauce
- 2 tablespoons (30 ml) mirin
- 1 tablespoon (15 ml) sake (optional, or substitute dry sherry)
- 1 tablespoon (15 g) sugar
- 1 medium onion (about 200 g), thinly sliced
- 4 large eggs (for the simmering step)
- 4 cups (700 g) cooked Japanese short-grain rice (from about 2 cups / 400 g uncooked)
- Thinly sliced green onions, for garnish
Instructions
- Pound and season the chicken: Place a chicken thigh between two sheets of plastic wrap and gently pound to an even 1/2-inch (1.25 cm) thickness. Season both sides with salt and pepper. Repeat with remaining thighs.
- Set up the breading station: Place the flour in a shallow dish, the beaten eggs in another, and the panko in a third. Dredge each thigh in flour (shake off excess), then dip in egg, then press firmly into panko until well coated. Set aside on a plate.
- Fry the cutlets: In a large skillet or Dutch oven, heat about 1/2 inch (1.25 cm) of oil over medium-high heat until a breadcrumb sizzles immediately when dropped in (around 350°F / 175°C). Fry the cutlets in batches, without crowding, for 2–3 minutes per side, until golden brown and cooked through. Transfer to a wire rack to drain. When cool enough to handle, slice each cutlet into 1-inch (2.5 cm) wide strips.
- Make the simmering broth: In a medium skillet (or the same skillet, wiped clean), combine the dashi, soy sauce, mirin, sake (if using), and sugar. Bring to a simmer over medium heat, stirring to dissolve the sugar.
- Add onion and chicken: Add the sliced onion and let it cook for 2 minutes until slightly softened. Lay the sliced chicken cutlets over the onion in a single layer.
- Add the egg: Beat the 4 eggs in a bowl. Pour the beaten eggs evenly over the chicken and onion. Cover the skillet and reduce heat to low. Cook for 2–3 minutes, until the egg is just set but still slightly runny (it will finish cooking from residual heat). The egg should be softly set, not hard.
- Serve: Divide the hot cooked rice among four deep bowls. Gently slide one quarter of the chicken-and-egg mixture onto each bowl of rice, letting the broth soak into the rice. Garnish with sliced green onions. Serve immediately.
Tips
- Use chicken thighs, not breasts: Thighs stay juicy and are more forgiving. If you use breasts, pound them thinner (1/4 inch / 0.6 cm) and watch cooking time to avoid dryness.
- Don’t overcook the egg: The egg should be custardy, not fully set. Remove the pan from heat while the egg is still slightly jiggly—it will finish cooking as you serve.
- Make your own dashi: If you don’t have dashi granules, use 1 cup water + 1 teaspoon kombu (kelp) powder or a pinch of hondashi. Or simply substitute 1 cup low-sodium chicken broth for a slightly different but still delicious broth.
- Keep the cutlets crispy: If you prefer extra crunch, you can skip simmering the cutlets and instead place them on top of the egg after it’s cooked. The traditional method simmers them, but it does soften the crust.
Serving Suggestions
Serve chicken katsudon as a complete meal. Pair it with a simple side of pickled vegetables (like Japanese tsukemono) or a light cucumber salad. A bowl of miso soup is a classic accompaniment. For a heartier dinner, add a small side of steamed edamame or a green salad with a ginger dressing.
Variations
- Pork katsudon: Substitute pork loin or tenderloin cutlets (pounded thin) for the chicken. Cook pork to a safe minimum internal temperature of 145°F (63°C) with a 3-minute rest before slicing.
- Vegetarian katsudon: Use thick slices of firm tofu or a large portobello mushroom cap, breaded and fried the same way. Simmer in the broth with the onion, then add the egg.
- Spicy katsudon: Add a teaspoon of gochujang (Korean chili paste) or sriracha to the simmering broth for a kick.
- Cheese katsudon: Place a slice of cheese (like mozzarella or cheddar) on top of the hot cutlet just before adding the egg, letting it melt.
Storage and Reheating
Store leftover katsudon (without rice) in an airtight container in the refrigerator for up to 3 days. Keep the rice separately. To reheat, place the chicken-and-egg mixture in a skillet with a splash of water or dashi, cover, and warm over low heat for 3–5 minutes until heated through. The egg will become firmer, but it will still taste good. Reheat the rice in the microwave or with a splash of water in a covered pan. For best texture, eat fresh—the cutlet loses its crispness when stored.
Frequently Asked Questions
Can I use chicken breast instead of thighs? Yes. Pound breasts to an even 1/4-inch (0.6 cm) thickness to ensure they cook quickly and stay moist. You may need to reduce frying time by about 1 minute per side.
What is dashi, and can I skip it? Dashi is a Japanese soup stock made from kelp and bonito flakes. It adds a subtle umami flavor. If you don’t have it, use 1 cup water + 1 teaspoon dashi granules, or substitute 1 cup low-sodium chicken broth for a richer, slightly different taste.
Why is my egg too runny? The egg should be softly set but not raw. If you prefer a firmer egg, cook for an additional 1–2 minutes, but be careful not to make it rubbery. The residual heat will continue cooking the egg after you remove the pan from the stove.
Can I make katsudon ahead of time? It’s best made fresh, but you can bread and fry the cutlets in advance, store them in the refrigerator for up to 2 days, and then simmer them with the egg when ready to serve. This saves time on a busy night.
What can I use instead of mirin? Mirin is a sweet rice wine. Substitute 1 tablespoon sugar dissolved in 1 tablespoon water, or use 1 tablespoon dry sherry mixed with 1/2 teaspoon sugar. This will slightly change the flavor but still work.
How do I know the chicken is fully cooked? The chicken should reach a safe minimum internal temperature of 165°F (74°C), as per USDA FSIS guidelines. Check with a food thermometer inserted into the thickest part of the cutlet before slicing. Since you slice the cutlet after frying, you can also check that the juices run clear.
