Breakfast & Brunch
This Hong Kong-style corned beef egg sandwich delivers the perfect balance of savory, salty, and creamy in every bite. The secret lies in tender, slow-cooked corned beef that practically melts on toasted milk bread, topped with a runny yolk that creates golden rivers when you take your first bite. Unlike the American version, this recipe incorporates traditional techniques—like steaming the corned beef for extra tenderness—and pairs it with crispy, buttery bread that holds up to the rich flavors.
What sets this sandwich apart is the wonton crust, a crispy, savory base that adds texture without overpowering the main ingredients. The egg, scrambled just enough to stay slightly runny, ties everything together with its velvety richness. I’ve perfected this recipe over years of Hong Kong café visits, ensuring the corned beef stays juicy and the bread stays perfectly toasted—no soggy bites here.
The result is a sandwich so good, it’s become a breakfast staple in Hong Kong bakeries. The buttery, slightly sweet milk bread contrasts beautifully with the salty corned beef and the creamy egg, while a drizzle of chili sauce or plum sauce adds the perfect tangy kick. It’s the kind of dish that feels indulgent yet simple, making it ideal for a weekend brunch or a quick, satisfying meal any day of the week.
Serve it with pickled vegetables or a side of soy sauce for dipping, and you’ve got a full Hong Kong-style breakfast experience. Ready to make the best corned beef egg sandwich you’ve ever had? Let’s get started.

The corned beef is everything here. Look for pre-cooked, thinly sliced corned beef at Asian grocery stores—they’ve got the perfect texture. Lotus or Golden Gate brands are my go-tos, but any good-quality brand works. If you can’t find pre-cooked, slow-cook your own with spices like bay leaves, cloves, and mustard seeds for that authentic flavor. The milk bread? Fresh from an Asian bakery is ideal—it’s got that perfect buttery crumb and slight sweetness. If you’re making it from scratch, don’t skip the milk in the dough. That’s what gives it that signature softness.
No wonton wrappers? Use spring roll wrappers instead—they’re thinner and crisp up better. Running out of chili sauce? Sriracha mixed with a pinch of sugar is a solid backup. The plum sauce can be swapped for a mix of hoisin and a splash of rice vinegar if you’re in a pinch. For the eggs, room temperature is key—cold eggs won’t scramble properly. Pro tip: Toast the bread in a dry pan for 30 seconds per side before assembling so it stays crispy. And if you’re feeling fancy, brush the toasted bread with a tiny bit of melted butter before adding the corned beef.
Assemble these sandwiches right before serving—they’re best eaten fresh. The wonton crust stays crisp for about 10 minutes after frying, so work quickly. Store any leftover corned beef in the fridge for 3-4 days in its juices, and the bread can be toasted ahead of time and reheated in the oven. The pickled veggies? Make a big batch—they keep for 2 weeks in the fridge and add that perfect tangy crunch to every bite. And if you’ve got leftovers, these sandwiches reheat beautifully in a toaster or skillet—just add a splash of water to keep the bread from drying out.

Step-by-step instructions for savory corned beef egg sandwiches
Here's how to assemble these Hong Kong street-style sandwiches with crispy wonton crusts and perfect runny yolks.
Prepare the Crispy Wonton Crust
Heat 2 tablespoons vegetable oil in a non-stick skillet over medium-high heat until shimmering. Place one wonton wrapper in the pan and press down gently with a spatula to help it crisp evenly. Cook for 1-2 minutes per side until golden brown and crispy—you'll see the edges curl slightly at the corners. Transfer to a paper towel-lined plate to drain excess oil.
Repeat with the remaining 3 sheets wonton wrappers, working in batches if needed. The key here is patience—don't rush the crisping or the crust will turn greasy instead of crispy. These wonton shells form the perfect crunchy base for your sandwiches, so take your time getting them just right.
Assemble the Corned Beef and Egg Filling
In a small bowl, gently mix the 1 lb corned beef with 0.5 cup pickled vegetables, 1 tablespoon soy sauce, and 1 tablespoon plum sauce. The pickled veggies add that signature tangy crunch while the sauces help bind everything together. Set aside while you prepare the eggs.
Crack each of the 4 whole large eggs into a separate small bowl. Season each lightly with 0.125 tsp salt and 0.0625 tsp black pepper—just enough to enhance the natural flavor without overpowering. These eggs will cook right in the sandwiches, creating those glorious runny yolk rivers when you bite in.
Build the Sandwiches with Perfect Layers
Place one crispy wonton wrapper on a clean work surface. Spread 1 tablespoon melted butter evenly over the surface—this helps create a golden seal when you close the sandwich. Add 2 slices milk bread on top of the butter, slightly overlapping the edges.
Spoon ¼ of the corned beef mixture over the bread, then carefully place one egg in the center. The egg should nestle comfortably without breaking. Top with another 2 slices milk bread and press gently but firmly to create a neat rectangular sandwich. Repeat with the remaining wonton wrappers, corned beef mixture, and eggs.
Cook to Golden Perfection
Heat a clean skillet over medium heat and add 1 tablespoon vegetable oil. Place one assembled sandwich in the pan and cook for 3-4 minutes per side until golden brown and crispy. You'll know it's ready when the bottom crust is deeply golden and the edges are slightly charred—this creates that irresistible crunch.
Transfer to a plate and keep warm while you cook the remaining sandwiches. For serving, drizzle each sandwich with 0.5 tablespoons chili sauce and cut diagonally in half. The contrast of crispy wonton crust, tender corned beef, pickled crunch, and that perfect runny yolk makes every bite unforgettable.
Pro Tips For Making Corned Beef Egg Sandwich Hong Kong
- CRISP THE WRAPPERS FIRST: Pop the wonton wrappers in a dry nonstick pan over medium heat for 10-15 seconds per side until they puff and turn golden—this gives your egg sandwich that signature crispy base. I used to skip this, thinking it was extra work, but it actually prevents soggy bread and adds texture that store-bought versions can’t match.
- USE COLD CORNED BEEF: Take the corned beef straight from the fridge and slice it thin—cold meat holds its shape better and won’t turn to mush when you assemble the sandwich. I learned this the hard way after my first attempt left me with a greasy, floppy mess.
- BUTTER THE BREAD INSIDE OUT: Spread butter only on the inside of the milk bread before adding the egg—this keeps the crust soft and prevents it from getting soggy from the egg’s moisture. Sounds weird, but it works: the butter seals the bread without making it greasy on the outside.
- EGG TEMPERATURE MATTERS: Fry the egg in a preheated nonstick pan over medium-low heat—too hot and it’ll scramble, too cool and it’ll be rubbery. A 3-minute cook time for runny yolks (or 4 for firmer) is your target. I was skeptical until I tried it: the right egg consistency makes all the difference in a Hong Kong-style sandwich.
Troubleshooting perfect results
Egg Too Runny?
If your eggs are too liquidy when you bite in, you likely overcooked the sandwiches. The secret is low-and-slow cooking—keep the heat at medium-low and cook for just 2-3 minutes per side instead of 3-4. I find that covering the skillet with a lid for the final 30 seconds helps set the egg whites while keeping the yolks runny. 💛
Corned Beef Dry?
Dry corned beef usually means it was overcooked or not properly rehydrated. If using pre-cooked slices, look for brands with extra moisture—Lotus or Golden Gate are my top picks. For homemade corned beef, simmer in water with a bay leaf and 1 tsp sugar for 10 minutes before slicing to restore tenderness. If already dry, try adding 1 tsp soy sauce or plum sauce to the filling to add moisture back.
Wonton Crust Too Greasy
Greasy wonton crusts happen when the oil isn't hot enough or you overcrowd the pan. Always use fresh vegetable oil (not butter) and heat the skillet until it's shimmering before adding the wonton wrappers. Work in batches if needed—2 wrappers max per pan. For extra crispiness, press down lightly with a spatula during the first 30 seconds of cooking. 🔥
Bread Getting Soggy
Soggy bread is the worst! To prevent this, toast your milk bread slices in a dry skillet for 20-30 seconds per side before assembling the sandwiches. I also recommend brushing the toasted bread with a thin layer of melted butter before adding the filling—this creates a moisture barrier. If your bread still gets soggy, try using thicker slices of milk bread or adding an extra wonton wrapper for insulation.
Filling Leaking Out
Loose fillings happen when the sandwich isn't pressed tightly enough. After adding the corned beef mixture and egg, press down firmly with a spatula to compress everything. For extra security, add a second wonton wrapper on the bottom layer before assembling—this creates a double seal. If the filling still leaks, try using slightly smaller bread slices (about ¼ inch thick) to contain everything better.
Chili Sauce Overpowering
If the chili sauce is too strong, balance it with 1 tsp plum sauce or a drizzle of honey before serving. For a milder heat, mix your chili sauce with equal parts mayonnaise to mellow the spice. I also recommend serving the sandwiches with pickled vegetables on the side—their tangy crunch helps cut through any overly spicy flavors. 🌶️

Frequently asked questions
Can I use regular bread instead of milk bread?
The buttery, slightly sweet flavor of milk bread is key to this Hong Kong recipe—it balances the salty corned beef perfectly. If you can't find milk bread, try a soft Hawaiian roll or brioche for the closest texture. Avoid dense breads like sourdough, as they won't hold up to the juicy filling.
How do I get the perfect runny yolk?
Use room-temperature eggs and cook the sandwiches over medium-low heat for just 2-3 minutes per side. Cover with a lid for the last 30 seconds to gently set the whites while keeping the yolks liquid. The secret is patience—overcooking turns yolks rubbery!
What's the best way to store leftovers?
Store the assembled sandwiches (without chili sauce) in an airtight container in the fridge for up to 2 days. Reheat in a toaster or skillet over low heat for 1-2 minutes per side—add a splash of water to prevent drying. Keep the wonton crusts separate if possible to maintain crispiness.
Can I make this sandwich gluten-free?
Yes! Replace the milk bread with gluten-free brioche or rice paper wraps and use tamari instead of soy sauce. For the wonton crust, look for gluten-free wonton wrappers (made with rice flour). The texture will differ slightly, but the flavors remain authentic.
Why does the wonton crust get soggy?
Soggy crusts happen when the filling is too wet or the sandwich isn't pressed tightly enough. Press the layers firmly before cooking, and consider adding an extra wonton wrapper as a barrier. Also, toast the bread slices first—this creates a moisture shield between the filling and crust.
