Vietnamese Egg Loaf Recipe: Fluffy Steamed Buns With Silky Yolk Hearts

This Vietnamese egg loaf recipe delivers the perfect balance of fluffy, airy buns with silky egg yolk centers that melt at the first bite. The secret lies in soaking the bread just right and achieving that signature custardy egg filling—something that transforms a simple breakfast into a showstopper.

I've perfected this technique after years of testing, ensuring every layer stays tender and the yolk remains perfectly runny.

The process begins with cubing soft white bread and soaking it in a warm milk-egg mixture until fully saturated but not soggy. This step is critical—over-soaking makes the buns dense, while under-soaking leaves them dry.

The egg mixture, enriched with a touch of sugar and vanilla, needs to be just thick enough to hold its shape when poured into the bread cubes, yet still flow smoothly into those little pockets.

What you'll end up with is a golden, steamed loaf that's light as a cloud on the outside and custardy in the center. The aroma alone will wake up your kitchen, and the contrast of warm, fluffy bread with that rich, creamy egg is pure comfort.

This recipe serves 6-8 and pairs beautifully with a side of pickled vegetables or fresh herbs for that authentic Vietnamese touch.

Whether you're making this for a special brunch or a weeknight treat, the technique is straightforward but requires patience—especially during the steaming process. The key is maintaining gentle heat to avoid overcooking the delicate egg centers. Let's get started on creating this Vietnamese breakfast masterpiece.

Ingredients for vietnamese egg loaf

Soft bread cubes, rich egg custard, and gentle steam create this Vietnamese breakfast masterpiece.

The bread is the foundation—day-old loaves work best (they're softer and absorb better). Sara Lee or Wonder White Bread are my go-tos, but any soft white bread with crusts removed works. Look for cubes that are 1-inch for even soaking. The milk should be warm but not hot—room temperature plus 30 seconds in the microwave. Too hot will cook the eggs prematurely. If you're short on time, whole milk powder works in a pinch, but fresh milk gives that authentic texture. For the egg mixture, room temperature eggs blend smoother and create a lighter custard—no need to stress if they're straight from the fridge, but let them sit for 10 minutes if possible.

No vanilla extract? Vanilla sugar at half the amount works, or 1 tsp vanilla sugar + 1/4 tsp water mimics the effect. The sugar amount is delicate—too much makes the buns gummy, too little leaves them bland. Substitute maple syrup at a 1:1 ratio if you prefer. For the butter, melted coconut oil is a dairy-free alternative that works beautifully. If you're serving this for a crowd, double the batch—the loaf keeps well for 2 days in the fridge or 1 month frozen. The pickled vegetables can be store-bought (like Trader Joe's quick-pickled carrots) or homemade for that authentic Vietnamese touch.

This loaf reheats beautifully—steam for 5 minutes to restore moisture. Store leftovers in an airtight container at room temperature for up to 8 hours or refrigerate for 2 days. For freezing, slice before freezing—wrap each slice individually in plastic wrap, then place in a freezer bag. Thaw overnight in the fridge before reheating. The egg centers stay perfectly runny when reheated gently. Garnish with cilantro and mint right before serving—it adds freshness that makes all the difference. This recipe is all about patience during steaming—don't rush it, or the yolk centers will overcook.

Step-by-step instructions for Vietnamese egg loaf

Transform simple ingredients into silky, golden buns with tender yolk centers.

Remove crusts from the 1.5 lb day-old soft white bread and cut into 1-inch cubes. Spread them evenly on a baking sheet and bake at 300°F for 10-12 minutes until completely dry. This step ensures the bread absorbs the egg mixture perfectly without becoming soggy.

While the bread dries, warm the 1.5 cups whole milk in a small saucepan over low heat until it reaches 110°F—just warm enough to feel slightly heated when you touch the back of your hand. This temperature prevents scrambling the eggs later while ensuring even absorption.

In a large mixing bowl, whisk together the 6 whole large eggs until they're frothy and pale yellow. Gradually add the 0.25 cup granulated sugar and 1 tsp pure vanilla extract, whisking constantly until the sugar dissolves completely. The mixture should be smooth and slightly thickened.

Slowly pour in the warmed whole milk while whisking gently to avoid creating air bubbles. Add the 0.5 tsp salt and mix until fully combined. This step creates the foundation for the egg loaf's signature tender texture and subtle sweetness.

Remove the dried bread cubes from the oven and let them cool slightly. Pour the egg mixture over the bread cubes in the mixing bowl and gently fold everything together using a rubber spatula. The bread should be fully coated, but avoid overmixing to prevent a dense texture.

Let the mixture sit for 10 minutes at room temperature. This allows the bread to absorb the liquid fully, creating a cohesive batter. The consistency should resemble thick pancake batter—just pourable enough to create smooth layers when steamed.

Grease an 8-inch round cake pan with 0.5 cup melted unsalted butter, coating the bottom and sides thoroughly. Pour the bread mixture into the pan and smooth the top with a spatula. Place the pan in a steamer basket over 1.5 cups water in a pot.

Bring the water to a boil, then reduce heat to medium-low and steam for 30-35 minutes. The loaf is done when the top is golden brown and a toothpick inserted in the center comes out clean. The yolk center should remain runny—this is the hallmark of a perfect Vietnamese egg loaf.

Remove the loaf from the pan and let it cool for 5 minutes. Slice into 8 equal wedges and serve immediately. Garnish each piece with 0.25 cup chopped fresh cilantro and 0.125 cup chopped fresh mint leaves for a vibrant finish.

For an authentic touch, serve with 1.5 cups pickled vegetables on the side. The tangy pickles contrast beautifully with the rich, creamy egg loaf, balancing flavors in every bite. The loaf's exterior should be tender yet slightly firm, while the yolk center remains silky and warm.

Storing and reheating this vietnamese egg loaf

Room Temperature Revival

If you've stored your Vietnamese egg loaf overnight, the best way to restore its freshness is to steam it for 5-7 minutes over boiling water. Place the entire loaf in a steamer basket lined with parchment paper (to prevent sticking) and cover with a damp kitchen towel.

The steam will revive the bread's moisture without overcooking the yolk centers. I always use a stainless steel steamer—it heats up faster and distributes steam more evenly than glass or ceramic. 🌟

Fridge Storage Secrets

For leftovers, wrap individual slices in plastic wrap and store them in an airtight container at the fridge's coldest setting (usually the back of the shelf). This keeps the bread fresh for up to 2 days while preserving the yolk's texture.

To reheat, I microwave each slice for 15-20 seconds on 50% power—just enough to warm through without turning the yolk rubbery. For a crispier texture, toast slices in a dry skillet over medium heat for 30 seconds per side.

Freezer-Friendly Slices

For longer storage, slice the loaf before freezing—this prevents freezer burn from affecting the entire piece. Wrap each slice tightly in plastic wrap, then place them in a freezer bag with all the air squeezed out. Label with the date and freeze for up to 1 month.

When ready to eat, thaw overnight in the fridge and reheat using the steaming method above. The yolk centers remain perfectly runny when reheated gently, just like fresh! ❄️

Garnish Refresh Tips

Fresh herbs like cilantro and mint lose their vibrancy when stored, so I recommend adding them right before serving—this keeps the presentation bright and the flavors fresh. If you're reheating, sprinkle the herbs on top just as you take the loaf out of the steamer or microwave.

For extra zing, add a squeeze of lime juice or a sprinkle of flaky sea salt to contrast the richness of the egg loaf.

Make-Ahead Shortcuts

Prep the egg loaf mixture the night before and store it in the fridge overnight. The flavors deepen, and the bread absorbs the liquid more evenly. When ready to steam, simply pour the mixture into the pan and proceed as directed.

This is my go-to method for weekend brunches—it cuts down on morning stress while delivering restaurant-quality results. Just
