1. Prepare the Eggs

Start by cracking the eggs into a medium-sized bowl. Use a whisk to beat the eggs gently until the yolks and whites are fully combined. Be careful not to overwhisk, as the goal is to maintain a smooth consistency. Once the eggs are beaten, add in the mayonnaise, sugar, salt, and a pinch of freshly ground black pepper. Mix the ingredients together until fully combined. The mayonnaise will provide the creamy texture and sweetness that characterizes the sandwich.

2. Cook the Eggs

Heat a non-stick frying pan over medium-low heat. If you want your sandwich to have a slightly crispy exterior, you can add a teaspoon of butter to the pan. Once the pan is heated, pour the egg mixture into the pan. Allow the eggs to set on the edges before gently stirring with a spatula. Scramble the eggs slowly and carefully to achieve a soft, creamy texture.

The key here is low and slow cooking. Don’t rush it! Stir the eggs occasionally, letting them form large, soft curds. After about 4-5 minutes, when the eggs are still soft but cooked through, remove them from the heat. You want the eggs to be slightly moist, as they will continue cooking from residual heat.

3. Prepare the Bread

While the eggs are cooking, toast the slices of bread lightly in a separate pan or toaster. In Japan, it’s common to use soft, slightly sweet milk bread, which adds a soft, fluffy texture to the sandwich. However, you can use any soft white bread that you prefer. If you’re looking for a crisp exterior, you can butter the bread before toasting it, which will add extra flavor.

Once toasted, you can trim the crusts off if desired. This is optional, but it makes the sandwich look more uniform and gives it a cleaner, more refined appearance.

4. Assemble the Sandwich

Once the eggs are ready and the bread is toasted, it’s time to assemble the sandwich. Place a generous amount of the scrambled eggs onto one slice of bread. You want a thick, even layer of eggs, so don’t be shy about how much you put on! Top with the second slice of bread.

If you’ve trimmed the crusts, you can carefully cut the sandwich in half to create two neat, bite-sized pieces. The result is a soft, creamy, and visually appealing sandwich that’s perfect for any time of day.

5. Serve and Enjoy

Your Japanese Egg Sandwich is now ready to be enjoyed! Serve it immediately for the freshest flavor and best texture. The combination of the creamy eggs and the soft bread is comforting and satisfying. Pair it with a hot cup of coffee or tea for a traditional Japanese breakfast experience, or enjoy it as a quick lunch or snack.
