What is Egg Salad Sandwich?
An egg salad sandwich is made by mixing boiled eggs with mayonnaise to create egg salad, which is then placed inside brioche bread or dinner rolls. The egg mayo salad in today’s recipe can be made in just five minutes in the microwave with no need to boil the eggs — it’s super simple!
Thanks to its easy preparation, delicious flavor, and soft, creamy texture, it’s a very popular breakfast option. It also makes a great lunchbox meal for school or work. Many people buy one for a quick lunch at a convenience store, Korean bakery, or café. It’s also a favorite for picnic lunch boxes!
Egg Mayo Sandwich From Japan?
In Japan, there’s a sandwich called a tamago sando. If you order one at a café, you’ll usually get a thick, fluffy rolled omelet tucked inside soft sandwich bread. It’s delicious from the first bite to the last.
However, at Japanese convenience stores, you’ll often find tamago sando made with egg salad inside thin bread. Today’s recipe uses this style of egg salad rather than a rolled omelet. We’ll also give it a Korean café twist by serving it in a crispy croissant to create a sandwich with a crispy exterior and soft, creamy interior.
A Popular Korean Cafe Menu
“Why is the Korean Egg Sandwich so popular?”
The egg mayo sandwich that I’m sharing with you today is a popular item that you can easily find at Korean bakeries and cafes. But why is it so beloved by Koreans?
- Taste: The combination of eggs and mayonnaise creates an incredibly soft, rich, nutty flavor that keeps you coming back for more.
- Convenience: It’s easy to make at home, and you can also find it at any convenience store or bakery. This makes it a perfect choice for a quick breakfast or lunch.
- Packed with protein: Compared to eating bread with just jam, which doesn’t keep you full for long, a protein-packed egg sandwich is much more satisfying and nourishing.
Korean Egg Mayo
In Korea, egg mayonnaise is hugely popular. You can even find it sold as a ready-made egg and mayo salad. We don’t just use it for sandwiches; we also enjoy it as a topping for various dishes.
One especially trendy way to enjoy it is with buldak ramen which you may already be familiar with. The rich, nutty mayo balances the intense spiciness of the buldak, creating a creamy, delicious combination.
Easy Microwave Recipe
Making the original egg and mayonnaise salad used to be quite a hassle. You need hard boiled eggs for egg salad sandwich, so you have to boil the eggs, chop the whites, mash the yolks, press them through a fine sieve, and finally mix in the mayonnaise to achieve a smooth, creamy texture.
But most Koreans are too busy with work or school to spend that much time. That’s why they usually buy it from a bakery or convenience store — or develop microwave recipes like today’s, haha. With today’s egg salad sandwich recipe, there’s no need to boil eggs. You can make egg salad in just 2 minutes using the microwave. It’s the perfect quick sandwich recipe for busy office workers and students.
If you have leftover eggs and mayonnaise, you can make this egg and mayonnaise toast in the microwave. It’s even simpler than today’s recipe, so on those days when you really don’t feel like cooking, it might be your saving grace!
The Uniqueness of Korean Sandwiches
- Sweet and Salty Flavors
Korean bakery café-style sandwiches may seem unusual to Europeans or Americans at first because they combine sweet and salty flavors. While people in Europe and the US are familiar with sweet toast with jam or Nutella, sandwiches with salty ham and cheese generally don’t include sweet ingredients.
In Korea, however, it’s common to add sugar, strawberry jam, or honey to sandwiches to give them a hint of sweetness. That’s why today’s recipe uses condensed milk.
- Bread
Where I live now in Belgium, Europe, people enjoy sandwiches made with crusty French-style baguettes. But in Korea and Japan, soft breads like milk bread or brioche are preferred for sandwiches. Koreans also love bread that is crispy on the outside yet soft on the inside, so croissants are a popular sandwich choice — including in today’s recipe.
- Eggs
Almost every Korean sandwich recipes include some form of egg, such as a fried egg, boiled egg slices, or egg salad. Think of egg drop sandwiches or gilgeori toast, also known as Korean street toast—eggs are practically essential!
