Cooking Instructions
Follow these simple steps to create your own delicious Tuna Katsudon:

- Prepare the Tuna: Gently pat the tuna steaks dry with paper towels. This will help the flour adhere better. Season both sides of the tuna steaks with salt and pepper.
- Bread the Tuna: Set up a breading station with three shallow dishes. In the first dish, place the all-purpose flour. In the second dish, put the beaten eggs. In the third dish, add the panko bread crumbs.
- Breading Process: Dredge each tuna steak in the flour, making sure to coat it evenly. Then, dip it into the beaten eggs, allowing the excess to drip off. Finally, coat the tuna steak with the panko bread crumbs, pressing gently to help them stick.
- Fry the Tuna: Heat the vegetable oil in a large skillet over medium-high heat. The oil should be hot enough so that the panko bubbles gently when a few crumbs are dropped in. Carefully place the breaded tuna steaks in the hot oil. Fry for about 2-3 minutes per side, or until golden brown and cooked through. Be careful not to overcrowd the pan; fry in batches if necessary.
- Remove and Drain: Remove the fried tuna steaks from the skillet and place them on a wire rack or paper towel-lined plate to drain excess oil.
- Prepare the Sauce: In a separate saucepan, combine the dashi, soy sauce, mirin, and sugar. Bring the mixture to a simmer over medium heat.
- Add the Onions: Add the thinly sliced onions to the simmering sauce. Cook until the onions are softened, about 5-7 minutes.
- Simmer the Tuna: Gently slide the fried tuna cutlets into the simmering sauce. Cook for about 1-2 minutes, allowing the sauce to coat the tuna.
- Add the Eggs: Pour the remaining beaten egg over the tuna and onions in the saucepan. Cover the pan and cook until the eggs are partially set but still slightly runny, about 1-2 minutes. This is a key element to authentic Tuna Katsudon.
- Assemble the Katsudon: Place a serving of cooked rice in a bowl. Carefully slide the tuna, onions, and egg mixture over the rice.
- Garnish and Serve: Garnish with chopped green onions, if desired. Serve immediately and enjoy your delicious Tuna Katsudon!
Serving Suggestions
Here are some ideas to elevate your Tuna Katsudon experience:

- Side Dishes: Serve your Tuna Katsudon with a side of miso soup, pickled vegetables (tsukemono), or a simple seaweed salad.
- Toppings: Add a sprinkle of sesame seeds or a dollop of Japanese mayonnaise for extra flavor.
- Spice: If you like a little heat, add a pinch of red pepper flakes (togarashi) to your Tuna Katsudon.
- Drinks: Pair your Tuna Katsudon with a cold glass of Japanese beer or a cup of green tea.
This Tuna Katsudon is best served immediately, while the tuna is still crispy and the egg is runny. However, leftovers can be stored in the refrigerator for up to 24 hours. Reheat gently in the microwave or on the stovetop.

Tips and Notes
- Tuna Selection: Use high-quality, sushi-grade tuna steaks for the best flavor and texture. Look for tuna that is firm, bright red, and has a fresh smell.
- Panko Bread Crumbs: Panko bread crumbs are larger and lighter than regular bread crumbs, which gives the tuna a crispier coating. You can find panko at most Asian grocery stores or in the international aisle of your local supermarket.
- Dashi Substitute: If you don’t have dashi on hand, you can substitute it with chicken broth or vegetable broth. However, dashi will provide a more authentic Japanese flavor.
- Egg Consistency: Adjust the cooking time of the eggs to your preference. If you like your eggs fully cooked, cook them for a longer period of time.
- Don’t Overcook the Tuna: Tuna is best served slightly rare or medium-rare. Overcooking the tuna will make it dry and tough.
- For a vegetarian option You could try substituting the tuna with thick slices of eggplant. Lightly salt the eggplant and let it sit to draw out excess moisture before breading and frying. The remaining recipe steps would remain the same.
