Baked Roast Pork Bun Recipe: Steamed Fluffiness With Savory Meat Stuffing

This baked roast pork bun recipe bridges tradition and convenience—steamed fluffiness meets tender, savory pork in one golden package. 🔥 I developed this after years of perfecting Asian-style roast pork (char siu) and adapting it for home ovens, because nothing beats the contrast of crispy buns and juicy meat.

The secret? A simple dough that bakes like steamed buns while keeping that signature melt-in-your-mouth texture.

What makes this recipe special is the balance of techniques: we start with a foolproof dough that puffs like traditional buns but bakes in your oven, then stuff it with marinated roast pork that stays juicy despite the heat.

The pork gets its signature sweet-savory glaze from a blend of honey, hoisin, and five-spice powder—a flavor profile I've perfected over years of cooking for crowds at The Smoky Pig. No steamer required, just your home oven.

By the time these buns emerge from the oven, you'll have golden, crisp-edged buns with tender interiors, filled with pork that's caramelized on the outside but still moist inside. The glaze clings to every bite, creating a perfect harmony of textures and flavors.

This is the kind of dish that transforms a simple meal into a celebration—whether you're feeding a family or hosting a gathering.

Serve with a side of plum sauce or a sprinkle of sesame seeds for extra flair. The buns reheat beautifully too, making them perfect for meal prep. Let's get started on creating these showstopping buns that taste like they came from a bustling Asian kitchen.

Ingredients for baked roast pork bun

Twelve ingredients. One showstopping dish. Sweet, savory, and crispy all in one golden package.

The pork shoulder is your flavor anchor—bone-in cuts stay juicier, and you can find them pre-cut at Costco or your local butcher. Look for well-marbled meat, not too lean. For the five-spice powder, Penzeys or Trader Joe's have the best toasted blends, but any Asian market will have authentic versions. The hoisin sauce? Lee Kum Kee is the gold standard—don't skimp on this. Fresh ginger and garlic are non-negotiable for that bright, aromatic punch. I always double-check the hoisin label for added sugar—some brands are sweeter than others, so adjust honey accordingly.

No five-spice powder? Mix 1 tsp each cinnamon, cloves, fennel, star anise, and black pepper—it's not identical, but it works in a pinch. Short on pork? Chicken thighs work surprisingly well, though the texture won't be exactly the same. For the dough, if you can't find instant yeast, use active dry yeast and let it proof 5 minutes longer. The sesame seeds can be skipped if you're in a hurry, but trust me on toasting them—they add that nutty crunch that ties everything together. And if you're making a big batch, double the dough recipe—these buns freeze beautifully.

Marinated pork keeps 3 days in the fridge, covered tightly. The dough can be prepped a day ahead and refrigerated until ready to use. For the final bake, these buns reheat beautifully—5 minutes at 350°F brings them back to golden perfection. I always make extra dough and freeze it in balls—just thaw and shape when needed. The pork filling? Freezes for 3 months too, so you can prep everything ahead and assemble as needed. Store leftovers in an airtight container, and they'll stay fresh for 4 days.

Step-by-step instructions for baked roast pork buns

Here's how to create tender, steamed buns with perfectly seasoned pork filling—every bite is a balance of fluffiness and savory goodness.

In a large mixing bowl, combine the 3 lb pork shoulder cut into 1-inch cubes with 0.5 cup hoisin sauce, 0.25 cup honey, 2 tbsp five-spice powder, 8 cloves minced garlic, 2 tbsp freshly grated ginger, and 0.25 cup soy sauce. Mix thoroughly until the pork is evenly coated in the marinade. Here's the thing—let it sit for at least 30 minutes (or up to 2 hours in the fridge) to allow the flavors to meld deeply into the meat.

After marinating, heat a skillet over medium-high heat and cook the pork for 8-10 minutes until the edges begin to brown. You'll know it's ready when the pork releases easily from the pan and has developed a beautiful caramelization. This step builds the foundation for that irresistible savory filling.

In a separate large bowl, whisk together 4 cups all-purpose flour, 2 tbsp instant yeast, 0.25 cup granulated sugar, and 1 tsp salt. Create a well in the center and pour in 1 cup warm whole milk (about 110°F) and 1 whole egg. Gradually mix until a shaggy dough forms, then add 0.5 cup vegetable oil and knead for 5-7 minutes until smooth and elastic.

Cover the bowl with a damp towel and let the dough rise in a warm place for 1-2 hours, or until it has nearly doubled in size. I like to place it near a slightly turned-on oven light for consistent warmth. The dough should be light and airy—this is what gives those buns their signature fluffiness. If it rises too quickly, it might collapse, so keep an eye on it.

Preheat your oven to 350°F and line two baking sheets with parchment paper. Divide the risen dough into 12 equal portions (about 3 ounces each). Roll each portion into a ball and flatten slightly into a disc. Here's where it gets fun—place 1-2 tablespoons of the cooked pork mixture in the center of each dough disc.

Gently seal the edges by pinching them together, then roll the dough around the filling to create a sealed, rounded bun shape. Place the buns on the prepared baking sheets, seam-side down, and let them rise again for 30-45 minutes until puffy. The second rise ensures they'll steam beautifully in the oven, giving that signature pillowy texture.

Brush the tops of the buns with a little egg wash (beat the remaining egg with 1 tablespoon water) for a golden finish. Bake for 25-30 minutes until the buns are deep golden brown and sound hollow when tapped on the bottom. I know it seems like too much, but trust me—this baking time ensures they're fully cooked through while maintaining that soft interior.

For extra flavor, sprinkle 0.25 cup toasted sesame seeds on top just before removing from the oven. Let them cool for 5 minutes before serving—this resting period helps them set properly and prevents the filling from oozing out. Serve warm with a side of hoisin sauce for dipping!
