You'll still get those familiar sweet-savory Chinese BBQ flavors, just without the grill, complicated glazing steps, or long cooking time.

What Is Char Siu?

Char siu (叉燒) is a Cantonese BBQ pork dish known for its caramelized exterior and sweet, savory glaze. Traditional char siu is usually made with pork shoulder or pork collar, which contain more fat and produce the signature deep color and glossy finish.

This recipe uses pork tenderloin instead, which:

• Cooks much faster
• Is leaner and lighter
• Stays juicy when cooked properly
• Has a cleaner, paler interior compared to traditional char siu

That's why this dish is best described as char siu style rather than classic restaurant char siu.

Why Traditional Char Siu Is Red (and Why This One Isn't)

If you've ordered char siu at a Cantonese BBQ shop, you've probably noticed its signature reddish color. Traditional char siu gets that color from red fermented bean curd (紅腐乳), and in many restaurants, a small amount of red food coloring is also added to enhance the appearance.

Red fermented bean curd has a slightly sweeter, more aromatic flavor than regular fermented bean curd (豆腐乳) due to the addition of red yeast rice, but both work well in home-style char siu marinades.

The red color is mostly visual, not a requirement for flavor. It helps char siu stand out in display cases and signals the classic Chinese BBQ style many people recognize.

This home-style version uses pork tenderloin and skips red food coloring, so it won't have the bright red exterior you may be used to. Instead, it focuses on the familiar sweet-savory char siu flavor with a simpler, more approachable method.

Want the Red Color? Here Are a Few Options

If you prefer a more traditional look, you can add color in a few easy ways:

• Red fermented bean curd (紅腐乳):
  Mash ½-1 cube into the marinade for deeper color and classic flavor.
• Red food coloring (optional):
  Add just 1-2 drops to the marinade for visual effect only. This is commonly used in restaurants.
• Paprika or annatto powder (natural option):
  These won't give the exact BBQ-shop red, but they can add a warmer hue.

Even with these additions, pork tenderloin will still look lighter than traditional char siu made with pork shoulder or pork collar due to its lower fat content.

How to make Char Siu Pork Tenderloin (Step by Step)

First, gather your ingredients:

• 1-2 pork tenderloins (Cut in half if too big to fit in marinade bowl or baking sheet)
• Marinade / Sauce
  • 2 tablespoon soy sauce
  • 1½ tablespoon sugar or honey
  • 1 tablespoon oyster sauce
  • 1 tablespoon Shaoxing wine or dry sherry
  • 3 cloves garlic, minced
  • ½ teaspoon five-spice powder
  • ½ cube fermented bean curd or red fermented bean curd

Note: This same mixture is used as the sauce later. We'll cook it after the pork goes into the oven.

Marinate the Pork

Mix all marinade ingredients in a bowl. Add the pork tenderloin and coat evenly. Cover and refrigerate until ready to cook.

How Long to Marinate

• Minimum: 30 minutes
• Best: 4-6 hours
• Max: Overnight (10-12 hours)

Because pork tenderloin is lean, avoid marinating longer than overnight.

Roast the Pork

1. Preheat oven to 425°F (220°C)
2. Line a baking sheet with foil
3. Remove pork from marinade and place on the pan
4. Roast for 15 minutes
5. Flip the pork and roast another 8-10 minutes

The pork is done when the internal temperature reaches 140-145°F.

Cook the Sauce

While the pork is in the oven:

1. Pour the leftover marinade into a small saucepan
2. Bring to a full boil
3. Boil 2-3 minutes to make it safe
4. Reduce heat and simmer 3-5 minutes until slightly thickened

This becomes your char siu-style sauce for serving.

Rest, Slice, and Serve

Let the pork rest for 5 minutes, then slice thinly against the grain.

Spoon the sauce over the pork or serve it on the side.

Storage & Reheat

How to Store

Let the pork cool completely before storing. Keep sliced or whole pork in an airtight container in the refrigerator for up to 3-4 days. Store the sauce separately in a small sealed container for best texture and flavor.

How to Reheat (Best Methods)

Stovetop (best texture)
Reheat pork gently in a pan over medium-low heat. Add a splash of water or a little sauce, cover, and warm just until heated through.

Microwave (quick option)
Place pork in a microwave-safe dish, spoon a little sauce over it, and cover loosely. Reheat in 30-second intervals until warmed through.

Because pork tenderloin is lean, avoid overheating or it can dry out.

Can You Freeze It?

Yes, but this dish is best enjoyed fresh. Freeze sliced pork without sauce for up to 2 months. Thaw overnight in the refrigerator and reheat gently.

Frequently Asked Questions (FAQ)

What should I serve with char siu pork?
Char siu pork pairs well with simple sides that balance its sweet-savory flavor. Try serving it with steamed jasmine rice, stir-fried greens like bok choy, broccoli, or green beans, noodles or fried rice, or tucked into bao buns or lettuce wraps.

Can I make this ahead of time?

Yes. You can marinate the pork up to 24 hours in advance and roast it when ready. The sauce can also be cooked ahead and reheated gently before serving.

Do I have to brush the pork with sauce while it cooks?

No. This recipe is designed so the sauce is cooked separately and served at the end, making it much easier and less stressful. If you prefer a glazed finish, you can reserve some of the marinade before adding it to the pork and brush it on halfway through cooking in the oven.

What if I don't have fermented bean curd?

That's completely fine. Fermented bean curd adds depth but it'll be ok without it. The pork will still be flavorful with soy sauce, sugar, garlic, and five-spice.

Can I use pork shoulder instead of tenderloin?

You can, but pork shoulder requires a longer cooking time and works better with traditional char siu methods. This recipe is optimized specifically for pork tenderloin.

Why did my pork turn out dry?

Pork tenderloin overcooks easily. For best results, pull it from the oven at 140-145°F, let it rest before slicing, and reheat gently.

Is this authentic char siu?

This is a home-style, simplified version inspired by classic char siu flavors. It's designed for ease and weeknight cooking rather than traditional BBQ roasting.
