This char siu roast pork recipe delivers the iconic Cantonese BBQ pork with crispy caramelized edges and tender, aromatic meat that'll transport you to Hong Kong dim sum stalls. 🌟 The secret lies in a five-spice marinade that penetrates deeply, followed by a honey-hoisin glaze that creates that signature sticky-sweet crust.
I've perfected this technique over years of cooking for crowds, ensuring every bite delivers that perfect balance of smoky, sweet, and savory flavors.
The process begins with marinating pork shoulder in a blend of hoisin sauce, honey, and five-spice powder for at least 12 hours (overnight is ideal), allowing the flavors to meld completely.

This is the kind of dish that impresses guests while being simple enough for weeknight dinners when you crave restaurant-quality flavors at home.
Serve it sliced thin over steamed rice, stuffed in bao buns, or even as tacos for a fusion twist. The leftovers reheat beautifully, making this an excellent make-ahead recipe for gatherings. Let's get cooking—this pork deserves to be the star of your table.
Ingredients for char siu roast pork
Six pounds of pork shoulder and just the right spices transform into restaurant-quality char siu.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Shoulder (Boston Butt) 🐷 | 4 lb | Bone-in, skin-on preferred |
| Hoisin Sauce 🍶 | ½ cup | Store-bought or homemade |
| Honey 🍯 | ½ cup | Wildflower preferred |
| Five-Spice Powder 🌶️ | 2 tbsp | Toasted for deeper flavor |
| Garlic Cloves 🧄 | 8 cloves | Minced for marinade |
| Ginger Root 🌿 | 2 tbsp | Freshly grated |
| Soy Sauce 🥢 | ¼ cup | Dark soy preferred |
| Sesame Oil 🫒 | 1 tbsp | Toasted sesame oil |
| Brown Sugar 🍚 | ¼ cup | Packed firmly |
| Red Fermented Beans (Hong Dou) 🌶️ | 2 tbsp | Optional, for depth |
| Red Food Coloring (optional) 🎨 | ½ tsp | For traditional mahogany hue |
| Cornstarch 🌾 | 1 tbsp | For glaze consistency |
| Kosher Salt 🧂 | 1 ½ tsp | For seasoning |
| Black Peppercorns 🌶️ | ½ tsp | Freshly cracked |
The pork shoulder is non-negotiable here—bone-in, skin-on gives the best flavor and texture. Costco or local butcher shops usually carry it at a great price. Look for good marbling and ask for a cut with some fat cap intact—this helps keep the meat juicy. If you're buying pre-cut, Trader Joe's often has decent quality at a reasonable price. The five-spice powder should be toasted for deeper flavor—Penzeys or Spicewalla are great sources, but the bulk bins at Asian markets are usually high-quality too. Don't skip the red fermented beans if you can find them—they add that authentic umami depth that sets char siu apart from regular BBQ pork.
No hoisin sauce? Substitute with 3 tbsp soy sauce plus 1 tbsp molasses—it won't be identical, but it'll work in a pinch. Fresh ginger is ideal, but dried ginger at half the amount works if you're in a hurry. The red food coloring is optional but worth it for that signature mahogany color—Walmart or grocery stores carry it in the baking aisle. If you're making this ahead, marinate the pork for 24 hours instead of 12 for even deeper flavor penetration. The sesame oil should be toasted—heat it in a pan for 30 seconds until fragrant before adding to the marinade. For extra authenticity, add a splash of Shaoxing wine to the marinade if you have it.
This pork tastes even better the next day once all the flavors meld together. Store leftovers in an airtight container in the fridge for up to 5 days, or freeze for 3 months by wrapping tightly in plastic wrap. For serving, slice against the grain into 1/4-inch thick pieces—this makes each bite more tender. The glaze thickens as it cools, so you can always add a splash of water when reheating. I like to keep a batch in the freezer at all times—perfect for quick weeknight dinners or last-minute gatherings when you need that restaurant-quality char siu.

Step-by-step instructions for char siu roast pork
Here's how to transform humble pork shoulder into restaurant-quality char siu with a caramelized glaze.
👨🍳 Step 1: Prepare the Marinade and Pork
In a medium bowl, combine the 0.5 cup hoisin sauce, 0.5 cup honey, 2 tbsp five-spice powder, 8 cloves minced garlic, 2 tbsp freshly grated ginger, 0.25 cup soy sauce, 1 tbsp sesame oil, 0.25 cup packed brown sugar, 2 tbsp red fermented beans, and 0.5 tsp red food coloring (if using). Whisk until the brown sugar dissolves completely and the mixture becomes smooth.
Pat the 4 lb pork shoulder dry with paper towels—this ensures maximum glaze adhesion. Place the pork in a large resealable bag and pour the marinade over it. Massage the marinade into all surfaces, working it into the crevices and fat cap. Seal the bag and refrigerate for at least 12 hours, preferably 24 hours, turning the bag occasionally to ensure even coating. The longer it marinates, the deeper the flavor penetration.
🔥 Step 2: Preheat and Sear the Pork
Preheat your oven to 325°F and position a rack in the lower third. Remove the pork from the marinade (reserve the marinade for basting) and place it fat-side up on a wire rack set in a roasting pan. This elevated position allows air to circulate around all sides, promoting even cooking and caramelization.
Roast uncovered for 1 hour to render some of the fat and begin cooking the pork gently. After 1 hour, brush the pork generously with the reserved marinade, then increase the oven temperature to 400°F. This higher heat will help caramelize the edges and create that signature char siu bark. Return the pork to the oven for another 30 minutes, basting with marinade every 10 minutes.
🍳 Step 3: Thicken the Glaze and Caramelize
While the pork roasts, combine the remaining marinade with the 1 tbsp cornstarch in a small bowl and whisk until smooth. This cornstarch slurry will help thicken the glaze and create that glossy, sticky finish. After the second 30-minute roast, brush the pork with this thickened glaze mixture, working it into all the crevices and edges.
Return the pork to the oven and roast for another 30-45 minutes until the internal temperature reaches 195-203°F (use a meat thermometer to check the thickest part of the shoulder). The edges should be deep mahogany brown with a glossy sheen, and the pork should pull apart easily with two forks. If the glaze starts to dry out before the pork is fully cooked, brush on additional marinade or glaze mixture.
⏰ Step 4: Rest and Slice for Maximum Juiciness
Remove the pork from the oven and transfer it to a cutting board. Tent loosely with aluminum foil and let it rest for at least 30 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, ensuring each slice is moist and flavorful. The pork should be fork-tender and pull apart easily, with a beautiful caramelized crust.
Slice the pork against the grain into ½-inch thick pieces. The grain direction will be visible as lines running through the meat. Arrange the slices on a serving platter and drizzle with any remaining pan juices or glaze. Serve immediately while still warm, accompanied by steamed rice and quick-pickled vegetables to cut through the richness.
Pro Tips For Making Char Siu Roast Pork
- Trim the Fat First: Boston butt has layers of fat that won’t render out during roasting—slice through them with a sharp knife before marinating. This lets the five-spice powder and hoisin cling to the meat instead of getting lost in grease, and it keeps your char siu from tasting like a greasy pork sandwich.
- Marinate Overnight, Not Just Hours: I used to think 4 hours was enough, but the five-spice powder and garlic need time to work their magic into the meat. Let it sit at least 12 hours—cover it tightly, or the pork will dry out. Trust me, the flavor difference is night and day, especially when you’re slicing into that sticky, aromatic crust.
- Roast at 325°F, Not Higher: Char siu needs low-and-slow to stay juicy, not a blast of heat that turns it into pork jerky. Start at 325°F for the first 2 hours, then crank to 425°F for the last 30 minutes to get that caramelized glaze. Skipping the low temp means tough, dry meat—no one wants that.
- Glaze in Stages: Don’t dump all the hoisin and honey at once—brush on half during the first hour, then add the rest 30 minutes before the end. This builds layers of flavor and prevents a sticky mess that won’t caramelize properly. Think of it like painting: thin coats dry faster and look better.
Perfect pairings for this char siu roast pork
Rice Pairings
Steamed jasmine rice is the classic choice—its floral aroma complements the sweet-savory char siu beautifully. I use 2 cups uncooked jasmine rice per pound of pork, steamed until just tender. For extra flair, add 1 tsp pandan extract to the cooking water for a fragrant twist. 🌟
For a heartier option, try fried rice with day-old char siu, scrambled eggs, and peas. I toss in 1 tbsp oyster sauce and a pinch of white pepper for depth. The contrast of crispy pork against tender rice is pure magic.
Bun Wraps
Char siu bao buns are a must—soft, steamed buns with the pork tucked inside. I use store-bought bao dough (like King's Joy) or homemade versions with 1 tsp baking soda for extra fluff. Add a drizzle of hoisin sauce inside for that authentic dim sum experience.
For fusion twists, try char siu tacos with corn tortillas, pickled jalapeños, and a squeeze of lime. The smoky pork pairs surprisingly well with Mexican flavors—my Atlanta diners love this combo! 🌶️
Sauce Dippers
A simple plum sauce (mix ½ cup hoisin, 2 tbsp rice vinegar, and 1 tsp grated ginger) cuts through the richness. I also keep sriracha mayo on hand for spicy lovers—just mix ¼ cup mayo with 1 tbsp sriracha.
For a tangy contrast, serve with quick-pickled cucumbers (slice 1 cucumber, toss with 2 tbsp rice vinegar, 1 tsp sugar, and ½ tsp salt). The crisp acidity balances the sweet glaze perfectly.
Side Dish Balance
Add stir-fried bok choy with garlic and chili for a veggie boost. I use 2 heads bok choy, 2 minced garlic cloves, and 1 tsp chili crisp for heat. The greens absorb the pork's flavors beautifully.
For a complete meal, serve with egg drop soup—its silky texture contrasts the pork's caramelized crust. I make mine with chicken broth, 2 eggs, and a pinch of white pepper. The warmth of the soup rounds out the dish. ✨

Frequently asked questions about char siu roast pork
Can I use pork tenderloin instead of pork shoulder?
While you can use pork tenderloin, it won't give you the same rich, tender results. Pork shoulder has more fat and connective tissue that breaks down beautifully during roasting, creating that signature melt-in-your-mouth texture. Tenderloin will be leaner and may dry out faster—consider using a smaller cut and reducing roasting time by 20-30 minutes.
What's the best way to store leftover char siu?
Store leftovers in an airtight container in the fridge for up to 5 days, or freeze for 3 months by wrapping tightly in plastic wrap. Reheat in a skillet over medium-low heat with a splash of water to restore moisture. The glaze may thicken when reheated—simply brush with a little extra hoisin sauce or honey to restore that glossy finish.
Why did my char siu turn out dry?
Overcooking is the most common cause—char siu should reach 195-203°F internally, not higher. Use a meat thermometer to monitor temperature. Also, patting the pork dry before marinating helps the glaze adhere better, but don't skip the 30-minute rest before slicing. If you're short on time, try roasting at 300°F instead of 400°F for a longer period to prevent drying.
Can I make char siu without hoisin sauce?
Yes! Mix 3 tbsp soy sauce, 1 tbsp molasses, and 1 tsp sugar as a substitute. For deeper flavor, add ½ tsp five-spice powder and 1 tsp grated ginger. While not identical, this combo will still give you that sweet-savory balance. The red food coloring (if using) will help achieve that traditional mahogany hue without hoisin's umami depth.
How do I get that perfect glossy glaze?
The secret is in the cornstarch slurry—whisk 1 tbsp cornstarch with 2 tbsp cold water and brush it on during the final 30 minutes of roasting. Broil for 2-3 minutes at the end to intensify caramelization. For extra shine, add ½ tsp sesame oil to the glaze mixture. The key is patience—rush the process and you'll get a dry crust instead of that sticky, glossy finish.
