Katsudon
Katsudon Rice Bowl with Custardy Eggs and Savory Broth
This comfort food classic transforms leftover fried cutlet into something magnificent. A sweet-savory dashi mixture cradles tender onions and crispy pork, all crowned with barely-set eggs that create an instant sauce when stirred into hot rice.
Katsudon feels like culinary alchemy — taking yesterday's fried cutlet and transforming it into something that feels entirely new and deeply comforting. This isn't just reheating leftovers; it's about creating layers of flavor and texture that work together in ways the original dish never could.
The magic happens in that sweet-savory dashi broth, which softens the onions while the cutlet absorbs just enough liquid to stay tender without losing its crispy edges. But the real star is those barely-set eggs, cooked just until they're creamy and custardy on top. When you break them with your chopsticks and stir everything into the rice, they become an instant sauce that coats every grain.
This is Japanese comfort food at its most practical and satisfying. It's the kind of dish that turns a simple bowl of rice into a complete meal, and it's probably why katsudon has been a staple at Japanese diners and home kitchens for generations. The technique is forgiving, the timing is flexible, and the results are consistently soul-warming.
Ingredients
- ⅓ cupdashi stock
- 1 tbspsoy sauce
- 1 tbspsake
- 2 tspgranulated sugar
- 2 tspmirin
- 4 ozyellow onion, thinly sliced(optional)
- 1 fried chicken or pork cutlet, cut into 1/2-inch strips
- 2 large eggs
- 2 scallions, sliced
- steamed rice
Instructions
- Whisk together the dashi, soy sauce, sake, sugar, and mirin in a medium saucepan. The sugar should dissolve completely as you bring the mixture to a gentle simmer over medium heat.
- Drop in the sliced onion if using and let it soften in the simmering broth until completely tender and slightly translucent, about 5 minutes. The onion will soak up the savory-sweet flavors.⏱ 5 min
- Nestle the cutlet strips into the broth and simmer for 1 minute to heat through. The crispy coating will stay intact while absorbing some of the flavorful liquid.⏱ 1 min
- Crack the eggs into a bowl and add most of the sliced scallions, reserving a few for garnish. Beat just until the whites and yolks are combined but still slightly streaky.
- Pour the beaten eggs evenly over the cutlet and onion, then immediately cover the pan. Cook for 1-2 minutes until the eggs are just set but still custardy on top—they'll continue cooking from residual heat.⏱ 1 min 30 sec
- Carefully slide the entire mixture over bowls of steamed rice, dividing evenly. Sprinkle with the reserved scallions and serve immediately while the eggs are still creamy.
Tips & Tricks
- Don't overcook the eggs — they should look underdone on top when you remove the pan from heat, as they'll continue setting from the residual heat and steam.
- If your cutlet has been refrigerated, let it come to room temperature for 10 minutes before adding to the broth so it heats evenly.
- Use day-old rice if possible — it holds its shape better and won't get mushy when the egg mixture is poured over it.
- Keep the broth at a gentle simmer throughout cooking; boiling will make the eggs rubbery and the onions mushy.
Frequently Asked Questions
Can I make this without dashi?
Yes, substitute chicken or vegetable broth, but add an extra teaspoon of soy sauce to compensate for the missing umami depth that dashi provides.
What if I don't have leftover fried cutlet?
You can use any breaded protein — frozen chicken tenders work well, or even leftover fried chicken. Just cut it into strips and proceed with the recipe.
Can I make this ahead of time?
Katsudon is best served immediately while the eggs are still creamy. The components can be prepped ahead, but the final assembly and egg cooking should happen right before serving.
Why are my eggs rubbery?
The heat was likely too high or you cooked them too long. Keep the broth at a gentle simmer and cover the pan as soon as you add the eggs — they should still look slightly wet on top when done.
