Maple Glazed Pork Belly Bao: Sticky, Steamed Buns

Jump to Recipe

Maple Glazed Roast Pork Belly Bao takes a slab of boneless pork belly, roasts it low and slow until it’s fork-tender, then finishes it under high heat with a maple-soy glaze that caramelizes into sticky, dark edges. The meat gets sliced thin and piled into pillowy steamed bao buns with a quick cucumber pickle for crunch.

I roast the belly covered for most of the cooking time so the fat renders slowly and the meat pulls apart easily, then I uncover it and crank the oven to get real caramelization on the glaze. The internal temp target is 195 F / 90 C, well past the food-safety minimum, because pork belly needs that extra time for the collagen to break down into something sliceable and tender instead of chewy.

This maple soy glaze is just maple syrup, soy sauce, hoisin, rice vinegar, garlic, and ginger simmered down until it coats a spoon. It’s sweet with a savory backbone, not candy-sweet, and it clings to the pork instead of pooling in the bun.

This one’s built for a lazy Sunday. The pork roasts mostly unattended, and you can steam the bao and mix the pickle while it rests.

Why You’ll Love This Recipe

• Pork belly roasts mostly hands-off for over an hour
• Maple-soy glaze caramelizes without turning candy-sweet
• Quick pickle adds crunch without extra cook time
• Works with store-bought frozen bao buns for a weeknight version

Ingredient Notes

• Pork belly: Use a boneless, skin-removed slab so it slices cleanly for bao filling. Ask your butcher to remove the skin if it’s still attached.
• Five spice powder: Gives the marinade its backbone. Garam masala isn’t a real substitute here, but a mix of cinnamon, star anise, and clove in a pinch will get close.
• Maple syrup: Use real maple syrup, not pancake syrup, since the flavor is doing real work in the glaze. Dark amber grade gives a stronger molasses note.
• Hoisin sauce: Adds body and a touch of five-spice funk to the glaze. Check the label if you need gluten-free, since some brands use wheat.
• Bao buns: Frozen steamed bao buns work fine and save time. Homemade dough is an option if you want a chewier, less sweet bun.
• Persian cucumber: Thin, crisp, and low on seeds, which keeps the quick pickle from turning watery. English cucumber works as a substitute.

Ingredients

  

Pork Belly and Marinade

• 900 g Boneless pork belly, skin removed about 2 lbs
• 1 tsp Five spice powder
• 4 Garlic cloves, minced
• 1 tbsp Fresh ginger, grated
• 3 tbsp Soy sauce
• 2 tbsp Shaoxing wine or dry sherry
• 1 tsp Salt
• 1/2 tsp Black pepper

Maple Glaze

• 60 ml Maple syrup 1/4 cup, real maple syrup
• 2 tbsp Soy sauce
• 2 tbsp Hoisin sauce
• 1 tbsp Rice vinegar
• 2 cloves Garlic, minced
• 1 tsp Fresh ginger, grated
• 1/2 tsp Chili flakes optional

Assembly

• 8 pieces Steamed bao buns frozen, store-bought or homemade
• 1 Persian cucumber, thin sliced
• 1 tbsp Rice vinegar for quick pickle
• 1 tsp Sugar for quick pickle
• 2 Scallions, sliced
• Fresh cilantro leaves small handful
• 1 tbsp Toasted sesame seeds

Method

 

Marinate and Roast the Pork Belly

1. Pat the pork belly dry with paper towels and place it in a baking dish.
2. Mix five spice, garlic, ginger, soy sauce, Shaoxing wine, salt, and pepper in a small bowl. Rub the mixture all over the pork belly.
3. Cover and marinate in the fridge for at least 30 minutes, or up to overnight for deeper flavor.
4. Heat the oven to 160 C / 320 F. Place the pork belly fat-side up in a roasting dish with 120 ml water in the bottom, and cover tightly with foil.
5. Roast for 80 minutes, until a fork slides into the meat with little resistance.

Make the Maple Glaze

1. While the pork roasts, combine maple syrup, soy sauce, hoisin, rice vinegar, garlic, ginger, and chili flakes in a small saucepan.
2. Simmer over medium heat for 3 to 4 minutes, stirring often, until the glaze thickens enough to coat the back of a spoon. Set aside.

Glaze, Finish, and Assemble the Bao

1. Remove the foil and increase oven heat to 220 C / 425 F. Brush the pork belly generously with half the glaze.
2. Roast uncovered for 15 to 18 minutes, brushing once more, until the glaze is caramelized and the internal temperature reads 195 F / 90 C.
3. Rest the pork belly for 10 minutes, then slice against the grain into 1 cm strips.
4. While the pork rests, toss cucumber slices with rice vinegar and sugar for a quick pickle. Steam the bao buns according to package directions, about 8 to 10 minutes.
5. Fill each bao with sliced pork belly, a drizzle of remaining glaze, quick pickled cucumber, scallions, cilantro, and sesame seeds. Serve warm.

Notes

• Roast pork belly covered for the first stage so the fat renders slowly.
• Don't skip resting the meat before slicing or it falls apart.
• Simmer the glaze until spoon-coating thick, thin glaze won't caramelize.
• Marinate at least 30 minutes, but overnight gives noticeably deeper flavor.

Tips for Success

• Pat the pork belly fully dry before rubbing on the marinade so the glaze caramelizes instead of steaming off.
• Use an instant-read thermometer and pull the pork at 195 F / 90 C for tender, sliceable meat.
• Simmer the glaze for 3 to 4 minutes until it coats the back of a spoon before brushing it on.
• Steam bao buns only for the package time listed, since oversteaming turns the dough gummy and dense.
• Rest the pork belly for 10 minutes before slicing against the grain for clean, even pieces.

Variations

• Swap five spice for gochujang and rice vinegar in the glaze for a spicier, Korean-leaning version.
• Use boneless chicken thighs instead of pork belly and cut roasting time to about 35 minutes at 200 C / 400 F.
• Top with crushed peanuts and extra cilantro for a banh mi-style crunch instead of the plain cucumber pickle.

Storage and Reheating

Store sliced pork belly in an airtight container in the fridge for up to 4 days. Keep the glaze, pickled cucumber, and bao buns separate so nothing goes soggy.

Reheat pork slices in a dry skillet over medium heat for 2 to 3 minutes per side, brushing with a little extra glaze if you have it. Steam bao buns fresh for 5 minutes, or microwave them wrapped in a damp paper towel for 20 to 30 seconds.

Pork belly also freezes well on its own for up to 2 months. Thaw overnight in the fridge before reheating in the skillet.

Serving Suggestions

Pile extra quick-pickled cucumber and thinly sliced scallion on the side so everyone can top their own bao. A simple cucumber and sesame salad keeps the plate light against the richness of the pork.

A bowl of steamed jasmine rice or a light miso soup rounds this out into a full meal if you’re serving more than snacks. For drinks, something acidic like a dry Riesling or a ginger beer cuts through the fat nicely.

Leftover sliced pork also works cold on a rice bowl with the same pickle and a drizzle of extra glaze the next day.

FAQ

Why is my maple glazed pork belly tough instead of tender?

Tough pork belly usually means it came out of the oven too early. Pull it at 195 F / 90 C, not the standard pork-safe minimum, since belly needs that extra time for the fat and collagen to break down. If it’s still firm at temp, give it another 10 to 15 minutes covered before checking again.

Can I use store-bought frozen bao buns instead of making dough for this recipe?

Yes, frozen steamed bao buns work well and cut the total time down a lot. Steam them straight from frozen according to the package, usually 8 to 10 minutes, and they’ll hold up fine against the warm pork and glaze. Homemade dough gives a chewier bite if you have the time.

How far ahead can I roast the pork belly for this bao recipe?

You can roast and slice the pork belly up to 2 days ahead and store it in the fridge. Reheat the slices in a skillet with a splash of glaze before assembling the bao. The glaze itself is best made fresh, but leftover glaze keeps in the fridge for about a week.

What goes well with maple glazed pork belly bao besides the cucumber pickle?

A simple sesame slaw, steamed jasmine rice, or a light miso soup all work well alongside these bao. The acidity in a quick pickled carrot or radish also cuts through the richness of the pork nicely. Keep sides simple so the pork and glaze stay the focus.

Is maple glazed pork belly bao gluten free?

Not as written, since regular soy sauce, hoisin, and most bao dough contain wheat. Swap in tamari for the soy sauce, check for a gluten-free hoisin brand, and use gluten-free bao buns or lettuce cups instead. Everything else in the marinade and glaze is naturally gluten free.

What’s the difference between this maple bao and classic Taiwanese gua bao?

Classic gua bao uses a braised, often skin-on pork belly with a savory soy braise and peanut powder, no maple. This version swaps the braise for a dry roast finished in a maple-soy glaze, which gives it a sweeter, more caramelized edge. Both use a folded steamed bun as the base.
