Ingredients for char siu roast pork
Six ingredients transform simple pork into Cantonese BBQ magic with sticky, caramelized perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Shoulder š„ | 4 lb | Bone-in, skin-on preferred |
| Hoisin Sauce š¶ | Ā½ cup | Store-bought or homemade |
| Honey šÆ | Ā½ cup | Wildflower preferred |
| Five-Spice Powder š¶ļø | 2 tbsp | Toasted for deeper flavor |
| Soy Sauce š¶ | ā cup | Dark soy for color |
| Brown Sugar š | Ā½ cup | Packed firmly |
| Garlic Cloves š§ | 8 cloves | Minced finely |
| Ginger šæ | 2 tbsp | Fresh, grated |
| Sesame Oil š« | 1 tbsp | Toasted for aroma |
| Rice Vinegar š¶ | 1 tbsp | White or seasoned |
| Salt š§ | 1 Ā½ tsp | Kosher or sea salt |
| Black Pepper š¶ļø | Ā½ tsp | Freshly ground |
| Cornstarch š¾ | 1 tbsp | For glaze thickening |
| Water š§ | 2 tbsp | For marinade thinning |
The pork shoulder is the starālook for bone-in, skin-on at your local butcher or Asian market for that authentic texture. Costco or Whole Foods usually carry it pre-cut, but if you're buying a whole shoulder, ask for the picnic cutāit's leaner and more flavorful. The five-spice powder? Penzeys has the best blend, but any reputable spice shop will do. Toast it in a dry pan for 30 seconds before adding to the marinadeātrust me, it makes all the difference. For the honey, wildflower or clover adds subtle floral notes that pair perfectly with the smoky pork.
No hoisin sauce? Mix 3 tbsp soy sauce, 2 tbsp honey, 1 tbsp rice vinegar, and 1 tsp sesame oilāit's a solid backup. Short on garlic? Garlic powder at half the amount works in a pinch, but fresh is non-negotiable for that authentic depth. The brown sugar can be swapped for white sugar plus 1 tsp molasses if that's what you've got. For the cornstarch glaze, arrowroot powder is a 1:1 substitute if you're avoiding gluten. The sesame oil is non-negotiable thoughāit's what gives that signature nutty aroma to the final dish.
Marinate the pork overnight in the fridgeā24 hours minimum for maximum tenderness. The sauce keeps for 5 days in the fridge, but the pork? Use within 3 days for best texture. If you're prepping ahead, freeze the marinated pork (uncooked) for up to 3 months

Step-by-step instructions for char siu roast pork
Here's how to create that iconic Cantonese sticky glazeācrispy edges and melt-in-your-mouth perfection.
šØāš³ Step 1: Marinate the Pork Shoulder for Maximum Flavor
In a large bowl, combine the 0.5 cup hoisin sauce, 0.5 cup honey, 0.33 cup soy sauce, 0.5 cup packed brown sugar, 2 tbsp five-spice powder, 1 tbsp sesame oil, 1 tbsp rice vinegar, 1.5 tsp salt, and 0.5 tsp black pepper. Whisk until the brown sugar dissolves completelyāthis prevents clumping later.
Add the 4 lb pork shoulder and turn to coat thoroughly. Cover and refrigerate for at least 12 hours (overnight is best). I like to flip the pork halfway through marinating to ensure even flavor penetration. This step is non-negotiableāit's what transforms ordinary pork into restaurant-quality char siu.
š„ Step 2: Roast Until Fork-Tender
Preheat your oven to 325Ā°F. Place the marinated pork shoulder on a rack set in a roasting pan (fat-side up if bone-in). Roast uncovered for 3 hours, then reduce heat to 275Ā°F and continue cooking for another 2-3 hours until the internal temperature reaches 195-203Ā°F and the meat pulls apart easily.
Here's the thingāpork shoulder needs patience. I check the temperature every 30 minutes after the 3-hour mark. The meat should feel tender but still hold its shape when you probe it. If it's not quite there, keep it in the ovenāit'll continue cooking as it rests.
š³ Step 3: Make the Signature Glaze
While the pork rests, make the glaze. In a saucepan, combine 1 tbsp cornstarch with 2 tbsp water to make a slurry. Add 0.5 cup hoisin sauce (reserved from marinade), 0.25 cup honey, and 0.16 cup soy sauce. Cook over medium heat until the mixture thickens to a syrupy consistencyāabout 3-4 minutes. It should coat the back of a spoon.
For that authentic char siu shine, I add 1 tbsp toasted sesame oil and 1 tbsp rice vinegar to the glaze. Taste and adjust seasoningāyou might need a pinch more salt or a splash of vinegar to balance the sweetness. Keep the glaze warm until ready to use.
šŖ Step 4: Caramelize the Glaze for Sticky Perfection
Slice the pork shoulder against the grain into Ā½-inch thick slices. Arrange them on a baking sheet lined with parchment paper. Brush each slice generously with the warm glaze, working quickly so it doesn't cool.
Transfer to a 450Ā°F oven and broil for 3-5 minutes until the glaze caramelizes to a deep amber color and forms those beautiful crackly edges. Watch carefullyāthis happens fast! The pork will be hot, so let it rest for 5 minutes before serving to let the juices redistribute.
š½ļø Step 5: Serve with Traditional Pairings
Arrange the char siu slices on a platter, brushing any remaining glaze over the top. Garnish with extra toasted sesame seeds if you like. Serve immediately with steamed jasmine rice, stir-fried bok choy, and a side of hoisin sauce for dipping.
Here's the magic: each bite should deliver tender, juicy pork with that perfect balance of sweet, salty, and aromatic five-spice flavors. The glaze should be sticky yet crispy, clinging to every slice like a perfect caramelized blanket. If you have leftovers, store them in the fridge for up to 3 daysāthey reheat beautifully!
Pro Tips For Making Char Siu Roast Pork
- Trim the Fat First: Score the pork shoulder before applying the marinadeācut through the thick fat cap in a crosshatch pattern. This lets the marinade penetrate deeper and keeps the meat from steaming in its own fat during roasting, so you end up with a crispier exterior and juicier interior. (Yes, even if youāre tempted to skip this stepātrust me, it matters.)
- Marinate Overnight, Not Hours: Char siu needs time to develop its deep flavor, but donāt assume a few hours will cut it. Aim for at least 12 hours, ideally 24, with the pork in the fridge. The five-spice and hoisin work their magic slowly, and rushing it leaves the meat tasting flat or overly sweet. (I learned this after a rushed batch that tasted like dessert, not pork.)
- Roast at 325Ā°F, Not High Heat: Start the pork in a cool oven (325Ā°F) for the first 45 minutes to render fat and cook the center evenly. Only crank it up to 425Ā°F for the last 15 minutes to blister the crustāthis prevents a gray, soggy exterior. (I used to blast it at 450Ā°F from the start, and the outside burned before the inside cooked.)
- Brush Twice, Not Once: Slather the hoisin-honey glaze on thick before roasting, then give it a second coat halfway through. The first layer caramelizes into a sticky shield, and the second adds gloss and depth. Skip the second brush, and youāll end up with patchy color and less flavor. (This is the difference between "meh" and "wow.")
Make-ahead tips for this dish
Marinade Prep
Start your marinade 2 days ahead if possibleāI find the flavors deepen significantly when the pork soaks up the spices overnight. Combine all marinade ingredients in a quart-sized zip-top bag (I use Hefty brand) and seal tightly.
Place the pork in the bag, submerge it completely, then massage the marinade into every crevice. Store in the fridge, turning the bag once daily. This method ensures even flavor distribution without drying out the meat. š
Freezer-Friendly Prep
For maximum convenience, marinate the pork as directed, then freeze it raw in the marinade. Use a freezer-safe vacuum sealer or heavy-duty freezer bag with all air removed. Label with the dateāthis keeps for 3 months.
When ready to cook, thaw overnight in the fridge, then proceed with roasting. The cold start helps prevent overcooking during the long roast. I do this weekly for my restaurant prep.
Glaze Pre-Make
Make the glaze 1 day ahead and store it in a small airtight container in the fridge. The cornstarch slurry thickens further overnight, creating a more concentrated flavor base.
Reheat gently in a saucepan with 1 tbsp water before brushing on the porkāthis prevents the glaze from cooling too quickly during the final broil. The pre-made glaze also lets you adjust seasoning without last-minute stress. āØ
Pork Pre-Roast
For a stress-free cooking day, prepare the pork for roasting the night before. After marinating, pat the pork dry with paper towels and wrap it tightly in plastic wrap. Place it on a tray lined with parchment paper to catch any drips.
Store in the fridge overnightāthis helps the crust form more evenly during roasting. Remove it from the fridge 1 hour before cooking to bring to room temperature gradually. This prevents temperature shock in your oven.
Leftovers Strategy
Slice the cooked pork completely and store it in a single layer on a tray before transferring to airtight containers. This prevents soggy slices from sticking together. Reheat portions in a skillet over medium heat with 1 tbsp water or broth to maintain moisture.
For a quick meal, slice the pork thinly and serve on steamed rice with a drizzle of extra glaze. The flavors actually improve after 24 hours as the spices meld further. š„
Make-Ahead Timeline
Here's my foolproof schedule: Day 1 - Marinate pork overnight. Day 2 - Roast pork (8-10 hours total), make glaze, then slice and refrigerate. Day 3 - Reheat portions as needed.
For parties, I'll slice and glaze the pork 2 hours before servingāthis gives the final caramelization time to develop while keeping the meat warm. The key is never to reheat the glaze-covered pork directly from the fridge; always bring it to room temperature first for even cooking.

Frequently asked questions about char siu roast pork
Can I use pork loin instead of pork shoulder?
Pork loin works but requires adjustments. It's leaner and cooks faster, so reduce roasting time to 1.5-2 hours at 325Ā°F until internal temp reaches 145Ā°F. The marinade time stays the same, but slice it thinner (Ā¼-inch) to prevent dryness. For best results, use pork loin with fat cap for moisture.
Why is my glaze too runny?
This usually happens when the cornstarch slurry isn't cooked long enough or the sauce was too watery. For quick fixes: simmer the glaze 2-3 more minutes until it thickens to a honey-like consistency. If it's still too thin, mix Ā½ tsp cornstarch with 1 tsp water and stir in. The glaze should coat the back of a spoon when cool.
How do I make this in an air fryer?
For air fryer char siu, marinate the pork as directed but use 1-inch thick slices instead of roasting a whole shoulder. Air fry at 375Ā°F for 8-10 minutes per side until internal temp reaches 145Ā°F. Brush with glaze, then air fry 2 more minutes at 400Ā°F for caramelization. Works best with pork tenderloin or boneless loin.
What's the deal with the five-spice powder?
Five-spice is a Cantonese blend of star anise, cinnamon, cloves, fennel, and Szechuan peppercornsāit's the aromatic soul of char siu. For homemade, toast the spices whole in a dry pan for 1 minute before grinding. Substitute with Ā½ tsp each cinnamon, cloves, and ginger powder if needed. The toasted version adds depth that store-bought blends often miss.
Can I grill this instead of roasting?
Grill the marinated pork over indirect heat at 250-275Ā°F for 2-3 hours, flipping occasionally. For smoky flavor, add Ā½ cup apple wood chips to the grill. Finish with the glaze by grilling 2-3 minutes over direct heat. The high heat helps caramelize the sauce quickly for that signature char siu look.
