Bánh Hỏi Thịt Heo Quay Recipe: Crackling Roasted Pork Meets Woven Rice Noodles

Some Vietnamese pairings work because the two halves are so different from each other. Bánh hỏi thịt heo quay (Bánh hỏi with crispy roast pork) is a case in point: a featherlight rice noodle set directly against pork roasted until its skin shatters like glass. Neither element would be especially memorable alone, the noodle is nearly flavourless by design, and roasted pork on its own can feel one-note after a few bites, but together, they create the kind of contrast that keeps a dish interesting from the first mouthful to the last. 

Below, you'll find a breakdown of what the dish involves, a full ingredient list, a method for roasting the pork properly at home, and a handful of questions worth answering before you start.

What Makes Bánh Hỏi Thịt Heo Quay Distinctive?

Bánh hỏi is unlike most rice noodles found in Vietnamese cooking. Rather than being extruded into loose strands, it is pressed into thin threads and woven into flat, lattice-like sheets before steaming, a process that gives it a texture closer to fine lace than to a typical noodle. Left plain, it tastes of almost nothing, rice, water, and little else.

Thịt heo quay (crispy roasted pork) is where all the flavour in this dish comes from. Pork belly is dried, seasoned, and roasted at escalating heat until the fat renders beneath a skin that has turned brittle and deeply coloured. Sliced and laid over the noodle, it supplies everything bánh hỏi lacks on its own: richness, crunch, and a savoury depth built up slowly through the roasting process.

A finished plate usually includes bánh hỏi, sliced roasted pork, scallion oil, a handful of fresh herbs, lettuce, pickled vegetables, and nước chấm on the side for dipping. Exactly how it's assembled tends to differ from one kitchen to the next. Some cooks lean heavily on five-spice in the marinade; others season the meat lightly and let the crackling do the talking.

• ½ tsp sugar

• ½ tsp white pepper

• 1 tbsp rice vinegar, for the skin

• 1 tbsp coarse salt, for drawing out moisture

For the scallion oil

• 3 stalks scallion, finely sliced

• 3 tbsp vegetable oil

• A small pinch of salt

Fresh accompaniments

• Mint and perilla

• Cucumber, sliced

• Pickled carrot and daikon (đồ chua)

Banh Hoi Thit Heo Quay Step-by-step Recipe

Step 1: Get the pork ready. Dry the pork belly thoroughly with paper towels, then score the skin in a shallow crosshatch, being careful not to cut through into the meat below. Season the underside only, five-spice, salt, sugar, and white pepper rubbed in well, leaving the skin bare. Draw out the moisture. Brush the skin with rice vinegar and press a layer of coarse salt over the surface. Refrigerate uncovered for a minimum of 4 hours, longer if you can manage it. Skipping or rushing this stage is the single biggest reason home-roasted pork skin fails to crisp.

Step 2: Roast in two stages. Start the oven at 160°C. Brush the dried salt off the skin, set the belly skin-side up on a wire rack, and roast for roughly 45 minutes. Turn the heat up to 220°C and continue for another 20 to 30 minutes, checking regularly, until the skin blisters into deep gold and amber. 

Step 3: Make the scallion oil. Warm the vegetable oil just short of smoking point, then pour it over the sliced scallion in a heatproof bowl. Add the salt and stir; the residual heat is enough to soften the scallion and pull out its aroma.

Step 4: Make the dipping sauce. Combine fish sauce, water, sugar, and lime juice, stirring until the sugar has fully dissolved. Fold in the garlic and chilli, then taste, it should land somewhere between sweet, sour, and mildly spicy, without any single note taking over.

Step 5: Rest, slice, and plate. Give the pork 10 minutes to rest once it's out of the oven, this keeps the juices in place and stops the skin from softening prematurely. Slice thinly, keeping the crackling attached to each piece. Lay the bánh hỏi out on a plate, brush with scallion oil, and arrange the pork on top. Surround it with lettuce, herbs, cucumber, and pickled vegetables, with the dipping sauce served alongside.

A couple of things worth remembering: the drying stage for the skin genuinely cannot be a shortcut, it's the difference between a shattering crust and a chewy, disappointing one. Resting the meat before cutting matters just as much, since slicing too early releases moisture straight into the skin. Pressed for time, a good roasted pork from a Vietnamese or Chinese barbecue counter works just as well here, no one assembling the plate at home will know the difference. And whatever you do, don't skip the scallion oil. Against pork this rich, the noodle needs that small hit of fragrance to avoid tasting flat.

Frequently Asked Questions

My pork skin didn't crisp properly. What went wrong? Nine times out of ten, it comes down to leftover moisture on the skin before it goes in the oven. Make sure it's been dried uncovered in the fridge for several hours, and keep salt and spice off the skin itself, seasoning there tends to interfere with crisping.

Can I prepare this in advance? The pork can be roasted a day ahead and briefly reheated in a hot oven to bring some crispness back, though it's at its best straight from the roasting rack. The dipping sauce holds up well in the fridge for several days. Bánh hỏi, on the other hand, should be assembled right before serving, since it dries out quickly once exposed to air.

Does Hanoi 1988 have this dish on the menu? It doesn't, currently. Hanoi 1988 focuses on northern Vietnamese cooking, phở and bún bò among its best-known dishes, both built on the same 24-hour broth and freshly made noodles the brand is recognised for.
