Baked Egg Puff Recipe: Crispy Wonton Shells With Runny Yolk Hearts

This baked egg puff recipe delivers crispy wonton shells with perfectly runny yolk centers—every bite is a textural masterpiece. The secret lies in a delicate balance of egg whites and yolks, baked just until the shells set while keeping the insides molten. I developed this recipe after years of experimenting with Asian-inspired breakfast dishes, and it's become a weekend staple that impresses even skeptical brunch guests.

The magic happens in the baking process: a high oven temperature creates those coveted crispy edges, while a water bath keeps the yolks gloriously runny. You'll need just five simple ingredients—wonton wrappers, eggs, a touch of cornstarch for texture, and optional seasonings like soy sauce or chili flakes. The dish comes together in under 20 minutes, making it ideal for busy mornings when you still want something special.

What you'll end up with is a plate of golden, crispy egg puffs that puff slightly as they cool, revealing those golden yolk hearts. The contrast between the delicate wonton shells and the rich, creamy yolks makes each bite unforgettable. These puffs are perfect for brunch gatherings, meal prep (they reheat beautifully), or even as elegant appetizers for dinner parties.

The best part? This recipe works equally well as a vegetarian main course or alongside other breakfast items. Garnish with fresh herbs, sesame seeds, or a drizzle of spicy mayo for extra flair. Here's how to create these restaurant-worthy egg puffs in your own kitchen.

Ingredients for baked egg puff

Five simple ingredients transform into crispy, golden egg puffs with molten centers.

Wonton wrappers are the star here—King Noodle or Tasty brand work best for that delicate texture. Grab a pack at Asian markets or the international aisle at Walmart or Target. They come in square or round, but square ones hold shape better. Keep them sealed until ready to use, or they'll dry out. The eggs? Room temperature is key—cold eggs won't whip as well, and you'll end up with dense puffs instead of light ones. If you're short on time, just crack them out 10 minutes before using.

No wonton wrappers? Phyllo dough works in a pinch—just brush with oil and fold differently. Short on soy sauce? A dash of fish sauce (if not vegetarian) or even a pinch of salt plus a splash of water gets you close. The cornstarch is non-negotiable though—it's what gives those puffs their signature crisp. For garnish, sesame seeds or furikake add that restaurant touch. No cilantro? Parsley or green onions work just as well. The spicy mayo? Mix mayo with a pinch of sriracha or chili flakes if you don't have store-bought.

These puffs reheat beautifully—just pop them in a 350°F oven for 5 minutes to crisp up again. Store leftovers in an airtight container for 2 days in the fridge, or freeze for 1 month. I always make a double batch: one for brunch, one for snacks. The shells stay crispy for hours at room temperature, but the yolks will firm up—so eat them fresh if you're craving that runny goodness.

Step-by-step instructions for crispy wonton egg puffs

Here's how to make golden, crispy wonton shells with perfectly runny yolks inside.

Crack all 6 whole Large Eggs into a bowl and separate the yolks from the whites. Place the yolks in one bowl and the whites in another. Add the 1 tbsp Cornstarch and 1 tsp Light Soy Sauce to the yolks, then whisk until fully combined. This coating helps create that signature crispy exterior while keeping the inside tender.

For the whites, add the 0.5 tsp Chili Flakes if you're using them, then whisk until soft peaks form. The chili flakes add a subtle kick that pairs perfectly with the richness of the eggs. If you skip them, the flavor will still be great—just milder. Keep the bowls separate until you're ready to combine them.

Lightly brush or rub 1 tbsp Vegetable Oil all over a standard muffin tin, making sure to coat every nook. This step is non-negotiable—without it, the wonton wrappers will stick to the tin and tear when you try to remove them. I like to use a paper towel to spread the oil evenly, especially around the edges of each cup.

While the tin is greasing, preheat your oven to 375°F. This temperature ensures the wonton wrappers crisp up just right without burning. If you don't have a muffin tin, a mini muffin tin or even a well-greased baking dish with individual wells will work in a pinch.

Carefully place 12 pieces Wonton Wrappers into the greased muffin tin, pressing them gently into the bottom and up the sides of each cup. You want them to form a snug, even layer that will hold its shape when baked. If any wrappers tear, patch them with small pieces of extra wonton wrapper—just be sure to press them firmly so they don't puff up unevenly.

Once all the wrappers are in place, pour the yolk mixture evenly into each wonton-lined cup, filling them about ¾ full. The wrappers should look taut but not stretched too tight. If they're too loose, the shells won't hold their shape. Place the tin on a baking sheet to catch any potential drips.

Bake the wonton shells in the preheated oven for 12-14 minutes until they turn a deep golden brown. You're aiming for that perfect crispy texture—when you tap the sides of the shells lightly with a spatula, they should sound hollow and feel firm to the touch. If you peek too early, the heat will escape, and your shells might not crisp up properly.

Once the shells are golden and crispy, remove them from the oven and immediately pour the egg white mixture over each one. The whites should fill the shells completely, creating a smooth, domed top. Return the tin to the oven for 8-10 more minutes until the egg whites are set but still slightly jiggly in the center.

Let the egg puffs cool for 2-3 minutes before removing them from the tin. If they're too hot, they'll fall apart when you try to transfer them. Use a small offset spatula to gently loosen the edges, then lift each puff out carefully. Place them on a serving platter and immediately drizzle with the 0.25 cup Spicy Mayo if you're using it.

Sprinkle with the 1 tbsp Sesame Seeds and 0.25 cup Fresh Cilantro, chopped finely. The sesame seeds add a nutty crunch, while the cilantro brings a fresh, bright contrast to the rich eggs. Serve warm for the best texture—crispy shells with that perfect runny yolk center. These puffs are best enjoyed right away, but you can store leftovers in the fridge for up to 2 days and reheat in the oven at 350°F for 5-7 minutes to restore crispiness.

Dietary considerations for these flavors

Vegetarian-Friendly

This recipe is naturally vegetarian—no meat or dairy (beyond eggs) is involved, making it perfect for plant-based diets or those avoiding animal products. The wonton wrappers are typically made from wheat flour and water, while the egg mixture provides all the protein. For a vegan version, simply replace the eggs with a chickpea flour batter (mix ½ cup chickpea flour with ½ cup water and 1 tbsp cornstarch) and bake at 375°F for 15-18 minutes. The texture won’t be identical, but it’s a great alternative! 🌱

Gluten-Free Adaptation

For a gluten-free twist, swap the wonton wrappers for gluten-free phyllo dough or rice paper wrappers. Phyllo requires brushing with melted butter or oil between layers to prevent cracking, while rice paper needs a quick dip in hot water before shaping. The egg mixture stays the same, but reduce baking time to 10-12 minutes to avoid over-browning. Test with a gluten-free soy sauce (like San-J brand) for umami depth. 🥟

Low-Carb Option

Cut carbs by omitting the wonton wrappers entirely and baking the egg mixture in greased mini muffin tins or silicon cupcake liners. Whisk 6 egg whites with 1 tbsp cornstarch and fold in the yolk mixture, then bake at 375°F for 12-14 minutes. These "naked" puffs are lighter but still crispy—perfect for keto or low-carb diets. Garnish with crushed pork rinds (if not vegetarian) or almond flour for crunch. ✨

Allergen Considerations

Watch for egg allergies—this recipe relies heavily on eggs, so it’s not safe for those with severe sensitivities. For cornstarch-free versions, substitute with arrowroot powder (use a 1:1 ratio). If avoiding soy, skip the soy sauce and use a pinch of salt plus a splash of water for flavor. Always check wonton wrapper labels for hidden allergens like wheat or sesame. Cross-contamination is key: use separate utensils and surfaces if preparing for someone with allergies. 💡

Nut-Free & Seed-Free

Skip the sesame seeds and spicy mayo (which often contains sesame) to accommodate nut/seed allergies. Garnish instead with toasted coconut flakes (if no coconut allergy) or crushed potato chips for crunch. For the mayo, mix vegetable oil mayo with a pinch of chili powder and lemon juice. Always verify labels—many store-bought garnishes hide nut traces. A simple salt sprinkle or smoked paprika keeps it flavorful without risk. 🌰
