Instructions
Step 1: Begin by heating the vegetable oil in a frying pan over medium heat. Add the sliced onion and cook it slowly until it becomes soft and golden brown, releasing a rich sweetness that forms the base of your dish. Next, carefully place the tonkatsu (crispy pork cutlet) in the center of the pan. Combine the vegetable stock, soy sauce, mirin, and sugar in a small bowl, stirring until the sugar fully dissolves. Pour about three-quarters of this savory-sweet mixture around the tonkatsu, ensuring it bathes in the flavorful liquid. Allow it to sizzle gently for a couple of minutes, which helps the sauce thicken slightly and warms the tonkatsu through, infusing it with depth. Step 2: Slowly and evenly pour the beaten eggs over the tonkatsu and onions in the pan. Cook for 2 to 3 minutes, letting the eggs set while remaining a touch runny to keep the texture luscious and tender. This gentle cooking helps the egg bind the ingredients without becoming rubbery. While the egg finishes cooking, divide the warm sushi rice evenly between two bowls. Once the eggs are ready, use a spatula to transfer half of the delicious tonkatsu and egg mixture onto each bowl of rice. Sprinkle chopped chives over the top for a fresh, mild onionness that brightens the dish. For an extra umami boost, drizzle a little more soy sauce just before serving. Enjoy your katsudon immediately while it’s warm and fragrant, savoring the harmonious layers of crispy pork, sweet onions, savory sauce, and creamy eggs.
