Quick Korean Egg Drop Sandwich (Gilgeori Toast)

Korean egg drop sandwiches, or gilgeori toast, are the street food breakfast that turns a few eggs and shredded cabbage into a warm, sweet-savory sandwich in about 15 minutes.

The fluffy omelette gets crisped in butter, then tucked into toasted bread with a ketchup-mayo sauce and a slice of cheese. It’s the kind of sandwich that makes a regular morning feel like you actually made something nice.

Why This Sandwich Works

The edges of the omelette get golden and lacy from the butter, while the center stays soft. That contrast in texture is the whole point—you get a little crunch, a little melt, and a little tangy sauce in every bite.

And the sauce? It’s just ketchup, mayo, and sugar whisked together, but it’s what makes this sandwich taste like the ones from the cart. Sweet, slightly tangy, and it soaks into the warm bread just a little.

Ingredients

• 4 large eggs: the base of the fluffy omelette
• 1 cup finely shredded green cabbage: adds crunch and bulk
• 2 tbsp finely shredded carrot: optional, for color
• 2 slices deli ham: optional, leave out for a vegetarian sandwich
• 2 slices American cheese: or any mild melty cheese like cheddar
• 4 slices soft white sandwich bread: brioche or milk bread work best
• 2 tbsp unsalted butter, divided: for cooking the omelette and toasting the bread
• 1 tbsp granulated sugar: sprinkled on the bread to caramelize
• 2 tbsp ketchup: base of the sweet sauce
• 2 tbsp mayonnaise: makes the sauce creamy
• 1 tsp sugar: for extra sweetness in the sauce
• ½ tsp rice vinegar: a little tang, optional

Variations / Substitutions

• Protein swap: use bacon, turkey, or a thin slice of spam instead of ham.
• Cheese: any cheese that melts works—cheddar, provolone, or even a slice of mozzarella.
• Bread: soft brioche is ideal, but any soft white sandwich bread will do. Whole wheat tastes earthier but works in a pinch.
• Vegetarian: skip the ham entirely; the sauce and cheese carry plenty of flavor.
• Spice: add a few drops of sriracha or a pinch of gochugaru to the sauce for heat.
• Dairy-free: use vegan butter and a plant-based cheese slice. Most white sandwich breads are dairy-free.
• If you like the sweet-savory vibe, you’ll probably enjoy Korean Street Toast, which adds more veggies and sometimes a hash brown patty right in the sandwich.

How to Make Korean Egg Drop Sandwich

Step 1: Mix the Sauce

Stir together 2 tbsp ketchup, 2 tbsp mayonnaise, 1 tsp sugar, and the ½ tsp rice vinegar if using. Mix for about 30 seconds, until smooth and there are no sugar granules visible.

The sauce should be pale pink and taste evenly sweet with a little tang. Set it aside so the flavors can mingle while you cook.

Step 2: Whisk the Eggs and Veggies

Crack 4 large eggs into a bowl. Add the 1 cup shredded cabbage and 2 tbsp shredded carrot if you are using it. Whisk for about 1 minute, until the whites and yolks are fully combined and there are no streaks, and the cabbage is evenly coated.

The mixture will look thin and eggy with specks of green and orange. A good whisk now means fewer patches of white in the cooked omelette.

Step 3: Cook the Omelette

Heat a medium nonstick skillet over medium heat. Drop in 1 tablespoon of the butter and let it foam, then pour in the egg mixture. Use a spatula to gently push the set edges toward the center while tilting the pan so raw egg runs underneath. Cook for 2 to 3 minutes, until the bottom is golden and the top is still slightly wet but mostly set.

Flip the omelette in one piece and cook the other side for another minute. The edges should be lacy and crisp. Traditional gilgeori toast folds the omelette into a square as it cooks—just fold the sides in with your spatula while the eggs are still pliable.

Step 4: Toast the Bread

Wipe out the skillet or grab a clean one. Melt the remaining 1 tablespoon butter over medium heat. Lay 2 slices of bread in the pan, then sprinkle half of the 1 tablespoon sugar evenly over the upward-facing side of each slice. Toast for about 1 minute, until the bottoms are golden and the sugar starts to look glossy and caramelized. Repeat with the other two slices.

The bread should be crisp and speckled with golden spots where the sugar melted. Keep an eye on it—the sugar goes from caramelized to burnt quickly.

Step 5: Assemble the Sandwich

Spread a generous spoonful of sauce on the untoasted side of two bread slices. On the other two slices, layer one slice of ham if using, one slice of cheese, and the folded omelette. Add a little more sauce on top of the omelette if you like it extra saucy. Close the sandwiches, sauce side down, and press gently.

Cut each sandwich in half diagonally and you will see the golden egg, the ribbon of cheese starting to melt, and the glossy bread. Serve right away while the omelette is warm and the bread is crisp.

A Few Notes Before You Start

• The sugar on the bread can burn in seconds, so stand by the pan while toasting.
• The sauce is forgiving—add more ketchup for tang or more mayo to mellow it out.
• These sandwiches really do not keep well. The bread steams and softens quickly, so eat them as soon as you assemble them.
• If you are making more than two, cook the omelettes one at a time and keep the finished ones on a plate in a warm oven while you toast the next batch of bread.

Frequently Asked Questions

Can I use a different cheese?

Yes, any mild melty cheese works. Cheddar, provolone, or mozzarella all melt well and taste good with the sweet sauce.

What if I don’t have rice vinegar?

You can skip it, or use a small squeeze of lemon juice to add a bit of tang.

Can I make the omelette without cabbage?

You can, but the texture will be different—more plain egg and less crunch. If you skip it, you might add a little extra egg or a slice of ham to keep the sandwich full.

Is this vegetarian without the ham?

Yes, the sandwich is vegetarian when you leave out the ham. The cheese and sauce carry plenty of flavor on their own.

Notes

The sandwich is best eaten right away, because the bread loses its crunch as it sits. If making multiple sandwiches, keep the cooked omelettes warm in a low oven while you toast the bread.
