Breakfast & Brunch
This Hong Kong-style corned beef egg sandwich delivers the perfect balance of crispy, toasted bread, tender corned beef, and a perfectly fried egg with a runny yolk that pools into golden rivers. 🔥 The secret lies in thinly sliced corned beef, a lightly toasted milk bread, and an egg fried to that signature Hong Kong runniness—where the yolk stays soft and creamy while the whites set just enough to hold the sandwich together.
The recipe captures the essence of Hong Kong street food, where every bite is packed with bold flavors and satisfying textures. The corned beef, often pre-cooked and sliced thinly, adds a savory depth, while the egg provides richness and moisture. Toasting the bread until it’s crispy on the outside but still soft inside is key—this is what makes the sandwich truly special, offering a satisfying crunch with every bite.
What makes this sandwich stand out is the attention to detail: the way the egg’s yolk melts into the corned beef and bread, the crispy edges of the toasted wonton cups (or milk bread), and the optional toppings like sweet chili sauce or butter that elevate the flavors. It’s a breakfast that feels indulgent yet simple, perfect for a quick morning meal or a satisfying brunch.
Whether you're making it for a lazy weekend morning or a weeknight breakfast, this recipe ensures you’ll have a sandwich that’s crispy, flavorful, and impossible to resist. Pair it with a cup of strong tea or coffee for the full Hong Kong café experience. Let’s get started!
Ingredients for corned beef egg sandwich hong kong
Crispy wonton cups, tender corned beef, and perfectly runny eggs—this Hong Kong classic needs just 11 ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Corned Beef 🥩 | 8 oz | Pre-cooked, thinly sliced |
| Large Eggs 🥚 | 4 whole | Fresh, room temperature |
| Wonton Cups 🥟 | 8 pieces | Frozen, thawed and dried |
| Milk Bread 🍞 | 1 loaf | Thinly sliced, crust removed |
| Unsalted Butter 🧈 | 2 tbsp | For toasting wonton cups |
| Sweet Chili Sauce 🍶 | 2 tbsp | Store-bought or homemade |
| Neutral Oil 🫒 | 2 tbsp | Vegetable or canola oil |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Sesame Oil 🫒 | 1 tsp | For finishing (optional) |
| Garlic Cloves 🧄 | 2 cloves | Minced, for optional topping |
The corned beef is non-negotiable here—pre-cooked and thinly sliced is key. Most Asian grocery stores carry the good stuff, like Char Siu-style or traditional Lap Cheong. If you can't find pre-sliced, grab a whole pack and slice it yourself with a sharp knife. For the wonton cups, Trader Joe's or H Mart always have them in stock. Pro tip: thaw and pat them dry with a paper towel before toasting to ensure maximum crispiness—this is what makes the sandwich special. Milk bread? Any soft, slightly sweet loaf works, but Tastee brand is the classic choice.
No wonton cups? Milk bread or brioche cut into rounds works in a pinch. Short on corned beef? Thinly sliced roast beef or pastrami gives a similar texture, though the flavor won't be quite the same. For the egg, freshness matters—room temperature eggs fry up better. Sweet chili sauce can be swapped for sriracha or hoisin sauce, depending on your heat preference. The sesame oil is optional but adds that authentic Hong Kong touch—use sparingly, as it's potent. If you're feeling fancy, add a sprinkle of toasted sesame seeds on top before serving.
Wonton cups crisp up best when toasted fresh—keep them warm in a 200°F oven while you fry the eggs. The corned beef stays fresh for 5 days in the fridge, but the eggs should be used within 3 days. For meal prep, assemble the sandwiches without the egg, store the components separately, and fry the egg to order. The crispiness of the wonton cups is best enjoyed immediately, though—reheating them makes them soft. Make a double batch of the filling and freeze it for up to 1 month—just thaw and assemble when ready.

Step-by-step instructions for crispy wonton cup egg sandwiches
Here's how to assemble these Hong Kong street-style sandwiches with perfect texture contrast.
🍳 Step 1: Toast Wonton Cups Until Golden and Crisp
Heat a skillet over medium heat and add the 2 tablespoons neutral oil. Place the 8 wonton cups in the pan, flat-side down, and cook for 2-3 minutes per side until they develop a deep golden brown color and crisp up. You'll know they're ready when they release easily from the pan—no sticking means they're properly toasted.
Don't overcrowd the pan or the wonton cups will steam instead of crisp. Work in batches if needed, but keep them warm while you prepare the other components. The crispy texture is what makes these sandwiches so satisfying—this step is non-negotiable for that authentic street food crunch.
👨🍳 Step 2: Prepare the Corned Beef and Milk Bread
While the wonton cups toast, slice the 1 loaf milk bread into 8 thin pieces (about ¼-inch thick). Arrange them on a cutting board and spread a thin layer of 2 tablespoons sweet chili sauce on one side of each slice. Then, layer the 8 oz sliced corned beef evenly over the sauce—just enough to cover each bread piece completely.
The corned beef should be spread in an even layer so each bite has consistent flavor. I like to press it down gently with a spatula to help it adhere. If you're feeling adventurous, sprinkle the 2 minced garlic cloves over the corned beef for an extra aromatic touch—just don't overdo it or the garlic will overpower the delicate flavors.
🍳 Step 3: Fry Eggs to Perfect Runny Yolk Stage
Heat a separate skillet over medium-low heat and add a thin layer of neutral oil (about ¼ teaspoon). Crack the 4 eggs into the pan, spacing them evenly. Cook for 2-3 minutes until the whites are set but the yolks remain completely runny—this is crucial for that signature Hong Kong-style egg sandwich texture.
Here's the thing—don't walk away. The moment the whites start to set but you can still see the clear egg liquid underneath, that's your signal to stop. The yolks should jiggle slightly when you shake the pan. If you cook them too long, you'll lose that luxurious runny center that makes these sandwiches so special. For extra flavor, sprinkle with ½ teaspoon salt and ¼ teaspoon black pepper while they cook.
🥘 Step 4: Assemble the Sandwiches with Crispy Layers
Place one toasted wonton cup on top of each corned beef-covered bread slice, pressing down gently to create a secure base. Then carefully place a fried egg on top of each wonton cup, allowing the runny yolk to pool slightly in the center. Drizzle with 1 teaspoon sesame oil (optional but recommended) for that authentic Hong Kong street food aroma.
For the perfect bite, the crispy wonton cup should contrast with the soft milk bread and runny yolk. I like to press down very lightly on the sandwich before taking the first bite—this helps the flavors meld together while keeping that crispy texture intact. The sesame oil adds a subtle nutty aroma that complements all the other flavors beautifully.
🍽️ Step 5: Serve Immediately for Maximum Enjoyment
These sandwiches are best enjoyed fresh out of the pan while the wonton cups are still crisp and the eggs are perfectly runny. Serve each sandwich cut in half with the crispy wonton cup side up—this makes it easy to hold and eat, just like you'd find them at a Hong Kong street stall.
For the full experience, pair with a cold drink or spicy dipping sauce. The contrast of textures—crispy wonton cups, soft bread, and runny yolk—is what makes this sandwich so special. Don't let them sit too long or the wonton cups will lose their crispness, and the eggs will firm up. Enjoy immediately for that authentic Hong Kong street food experience!
Pro Tips For Making Corned Beef Egg Sandwich Hong Kong
- Preheat Your Pan: The corned beef should sizzle immediately when it hits the pan—no waiting. I used to rush this and end up with soggy wonton cups. Heat your nonstick skillet over medium-high for 2-3 minutes until a water droplet dances on the surface before adding butter.
- Dry the Corned Beef: Pat those slices thoroughly with paper towels—wet meat steams instead of sears. I learned this the hard way when my first batch turned out greasy and undercooked. Even if it feels dry, give it another wipe.
- Eggs at 160°F: The yolks should be just set but still runny—no waiting for 170°F or you’ll kill the custard. Use a thermometer or cut one open: if the center’s slightly wobbly, it’s perfect. Overcooked eggs ruin the whole sandwich.
- Butter the Bread Last: Toast the milk bread first, then butter it after assembly. Cold butter melts into the sandwich, making it soggy. A quick brush of warm butter on the inside of the toasted bread keeps it crisp while adding richness.
Dietary considerations for corned beef egg sandwich hong kong
Gluten-Free Adaptations
For a gluten-free version, replace the wonton cups with gluten-free wonton wrappers or gluten-free puff pastry cups—brands like King Arthur or Udi's make excellent substitutes. Use gluten-free milk bread or a soft gluten-free baguette for the base, ensuring all ingredients are certified gluten-free to avoid cross-contamination. 🌱
Dairy-Free Options
Skip the butter when toasting the wonton cups and use neutral oil instead. For the milk bread, opt for dairy-free bread like Schar or Canyon Bakehouse brands. The sweet chili sauce and corned beef are naturally dairy-free, so the only adjustment is the bread and toasting method.
Low-Carb Variations
Swap the milk bread for low-carb tortillas or lettuce wraps to reduce carbs. Use sugar-free sweet chili sauce (like Cholula Sweet Chili) and skip the sesame oil if you're strict about carbs. The crispy wonton cups can be replaced with low-carb tortilla cups for a similar texture.
Egg Allergies
For those avoiding eggs, try a tofu scramble or avocado mash as a substitute. Cook firm tofu in a pan with turmeric, salt, and pepper until it mimics the texture of a fried egg. Serve it on top of the corned beef and wonton cup assembly for a similar experience.
Vegetarian Substitutes
Replace the corned beef with marinated tofu or mushroom jerky for a meat-free version. Use vegan sweet chili sauce (like Annie Chun's) and ensure the wonton cups are vegetarian-friendly. The crispy texture and runny yolk (or tofu alternative) remain the star of the sandwich.

Frequently asked questions
Can I use regular bread instead of wonton cups?
Yes, but you'll miss the signature crispy texture! Use thinly sliced milk bread or brioche and toast it in butter until golden. For extra crunch, press the bread slices between two sheets of parchment paper with a heavy pan to create a crispy base before assembling.
How do I get the perfect runny yolk in my egg?
Cook eggs over medium-low heat with just enough oil to coat the pan. Remove them when whites are set but yolks still jiggle slightly—about 2-3 minutes. The key is patience: overcooking turns the yolk firm. For extra insurance, use very fresh eggs from the fridge.
What's the best way to store leftovers?
Store components separately to preserve texture. Keep corned beef and bread in the fridge for 3 days, and wonton cups in an airtight container for 2 days. Fry eggs fresh to order—they won't reheat well. For make-ahead prep, assemble sandwiches without eggs and store in the fridge, then fry eggs when ready to eat.
Can I make this sandwich without sweet chili sauce?
Try hoisin sauce, mayonnaise, or even butter for a different flavor profile. For a spicy kick, mix sweet chili with a dash of sriracha. The sauce just helps bind the corned beef to the bread—any spreadable condiment works in a pinch.
Why did my wonton cups get soggy?
Overcrowding the pan or keeping them warm too long causes sogginess. Toast in batches and store finished cups in a 200°F oven for no more than 5 minutes. For extra crispiness, toast them twice—once before assembly, and again briefly after adding the egg.
