Delicious Egg Tarts Recipe: Crispy Wonton Shells With Perfect Runny Yolk

This delicious egg tart recipe delivers the perfect balance of crispy wonton shells and a luscious, runny yolk center. 🔥 The secret lies in the right egg custard ratio and baking technique—no more dry or overcooked tarts. I've perfected this version after years of trial and error, and it's become a weekend favorite that disappears faster than you can say "more, please!" The magic starts with the wonton wrappers, which need to be baked just until golden and crispy before adding the custard. This ensures they hold their shape while still being tender enough to bite through. The egg filling is where things get interesting—it's all about achieving that signature runny yolk that pools beautifully when you cut into it. By the time you pull these out of the oven, you'll have egg tarts with perfectly crisp shells and custards so rich and creamy they practically melt in your mouth. The aroma alone will have everyone gathering around your kitchen, and the first bite will have them begging for the recipe. Trust me, this is the version that actually lives up to the hype. Serve them warm with a sprinkle of flaky salt or a drizzle of honey for that extra touch of indulgence. These tarts are perfect for breakfast, brunch, or even as a sweet snack. Let's get baking!

Ingredients for delicious egg tart

Crispy shells meet gooey centers—just nine ingredients for egg tarts that disappear fast!

Wonton wrappers are the star here. King's Wonton Wrappers from the Asian market are my go-to—they're sturdy enough to hold the custard without falling apart. If you can't find them, any square wonton wrappers work, but round ones won't crisp up the same way. Store them in the fridge until ready to use—no need to thaw. The eggs? Freshness matters—crack them into a bowl first to check for any weird colors or smells. Room temperature eggs blend smoother into the custard, so take them out 30 minutes before mixing.

No flaky sea salt? Diamond Crystal kosher salt works in a pinch—just sprinkle it lightly. Want to skip the honey drizzle? A pinch of cinnamon or a dusting of powdered sugar gives a nice contrast instead. The butter should be cold when baking the shells—this ensures they stay crispy. If your custard seems too thick, add a splash more milk. Too thin? Stir in a teaspoon of flour. And trust me, don't skip the oil brushing—it's what makes those shells golden and irresistible.

These taste even better the next day, but the shells lose crispness after 2 days. Store in an airtight container at room temperature. For reheating, pop them in a 350°F oven for 5-7 minutes until warm and crispy again. Make a double batch—they vanish faster than you can say "more, please!" Freeze extras wrapped individually for up to 1 month. Just bake straight from frozen, adding 2-3 extra minutes.

Step-by-step instructions for crispy egg tarts

Here's how to make egg tarts with golden shells and silky runny yolks—every time!

Crack the 6 whole Large Eggs into a mixing bowl and whisk them vigorously until they're completely smooth and frothy. This step is crucial—those air bubbles help create the signature silky texture. Add the 0.5 cup Granulated Sugar and whisk until fully dissolved. The mixture should look pale and slightly thicker.

Next, add the 0.5 cup Milk and 0.25 cup All-Purpose Flour to the egg mixture. Whisk continuously for 1-2 minutes until the batter is smooth and glossy. Here's a pro tip: strain the mixture through a fine-mesh sieve to remove any lumps. This ensures your filling will be perfectly smooth and velvety when baked.

Preheat your oven to 375°F and line a baking sheet with parchment paper. Cut the 12 whole Wonton Wrappers diagonally into 24 triangles—this gives you the classic egg tart shape. Brush each triangle lightly with 2 tablespoons Vegetable Oil using a pastry brush, focusing on the edges. The oil helps create that beautiful golden-brown crust.

Place one triangle in each spot on your prepared baking sheet. Spoon about 1 tablespoon of the egg filling into the center of each wrapper triangle. Fold the corners over the filling to form a neat little package. Press down gently on each corner to seal—this prevents the filling from leaking during baking. Arrange them about 1 inch apart for even browning.

Bake the egg tarts for 18-22 minutes until the shells are deep golden brown and the filling is just set. Here's the key: you want the centers to look slightly underdone when you remove them from the oven. The residual heat will finish cooking the filling perfectly. If you're unsure, cut one open—you're looking for a runny yolk that wobbles slightly when the tart moves.

I like to rotate the baking sheet halfway through baking (after 10-12 minutes) for even browning. As soon as they're done, transfer the tarts to a wire rack to cool for 5 minutes. This resting period is important—it allows the filling to set just enough to hold its shape when you serve it.

While the tarts are still warm, drizzle each one with 1 teaspoon Honey (about 2 tablespoons total) for that classic sweet glaze. Sprinkle generously with 1 tablespoon Flaky Sea Salt right after drizzling—the salt should stick to the honey for that perfect balance of sweet and salty. Let them sit for 2 minutes so the honey sets slightly.

Serve the egg tarts warm—this is when they're at their best! The contrast of the crispy, golden shell with the silky, runny yolk inside is what makes these egg tarts so irresistible. For extra indulgence, serve with a cup of strong tea or coffee. The warm filling will melt slightly with each bite, creating that perfect mouthfeel.

Pro cooking tips for delicious egg tart

Egg Filling Secrets

The key to that signature runny yolk lies in the egg custard ratio—I use 6 whole eggs for a rich, velvety texture. Whisk them until completely smooth (no streaks!) to incorporate air bubbles that prevent a dense filling. For extra silkiness, strain the mixture through a fine-mesh sieve after adding flour and milk. This removes any lumps that could make your custard grainy. 🥚

Shell Crispiness Tricks

Wonton wrappers need oil brushing—use 2 tbsp vegetable oil (I like Avocado Brand) and focus on the edges. This creates that irresistible golden-brown crust. Bake at 375°F until shells are deep golden, but don't overbake—they should hold their shape when cool but still feel tender. For even browning, rotate the pan after 10-12 minutes.

Baking Time Mastery

Your oven's hot spots matter! Place tarts on the middle rack for even heat distribution. Bake for 18-22 minutes—the filling should look just set with a slight wobble in the center. If unsure, cut one open: the yolk should be runny but not liquid. Overbaking turns custard rubbery, so trust your eyes more than the timer. ⏰

Assembly Pro Tips

Cut wonton wrappers diagonally for classic egg tart shape. Fold corners gently but firmly to seal—press just enough to prevent leaks. Use 1 tbsp filling per tart (about 24 total) and space them 1 inch apart on the baking sheet. This ensures even browning and prevents steam buildup that can make shells soggy.

Finishing Touches

Drizzle honey immediately after baking while shells are still warm—they'll absorb it better. Sprinkle flaky sea salt (I use Maldon) right after for that perfect sweet-salty contrast. Let them rest 2 minutes before serving so the honey sets slightly. Serve warm with strong black tea or coffee for the full experience. 💫

Troubleshooting Leaks

If filling leaks during baking, your corners weren't sealed tightly enough. Press them firmly but gently—too much force can tear the wrappers. For extra insurance, chill the assembled tarts in the fridge for 10 minutes before baking. This helps the filling set slightly before hitting the oven, reducing leaks. 🔥
