This Japanese char siu recipe brings a delightful twist to the traditional Chinese barbecue pork. The tender, flavorful pork belly is slow-cooked in a savory-sweet marinade, making it a perfect addition to your ramen or rice dishes. The combination of soy sauce, mirin, and sake creates a rich, umami-packed glaze that caramelizes beautifully in the oven.
Some of the ingredients in this recipe might not be staples in every kitchen. Mirin is a sweet rice wine used in Japanese cooking, and sake is a Japanese rice wine that adds depth to the dish. Both can be found in the Asian section of most supermarkets. If you can't find them, they are available at specialty Asian grocery stores or online.
Ingredients For Japanese Char Siu Recipe
Pork belly: A fatty, flavorful cut of meat that becomes tender and succulent when slow-cooked.
Soy sauce: Adds a salty, umami flavor to the marinade.
Mirin: A sweet rice wine that balances the saltiness of the soy sauce.
Sake: A Japanese rice wine that adds depth and complexity to the marinade.
Sugar: Sweetens the marinade and helps with caramelization.
Garlic: Adds a pungent, aromatic flavor to the dish.
Ginger: Provides a warm, spicy note that complements the other flavors.
Technique Tip for This Recipe
When preparing pork belly for this Japanese Char Siu, make sure to score the skin lightly in a crosshatch pattern. This allows the marinade to penetrate deeper into the meat, enhancing the flavor. Additionally, basting the pork occasionally while baking ensures it remains moist and absorbs the sauce evenly.
Suggested Side Dishes
Alternative Ingredients
boneless pork belly - Substitute with boneless pork shoulder: Pork shoulder has a similar fat content and texture, making it a good alternative for slow-cooked dishes.
soy sauce - Substitute with tamari: Tamari is a gluten-free alternative to soy sauce with a similar umami flavor.
mirin - Substitute with dry sherry: Dry sherry provides a similar sweetness and depth of flavor, though it is slightly less sweet than mirin.
sake - Substitute with dry white wine: Dry white wine can mimic the acidity and complexity of sake in cooking.
sugar - Substitute with honey: Honey adds sweetness and a slight floral note, though it is sweeter than sugar, so use slightly less.
minced garlic - Substitute with garlic powder: Garlic powder can provide a similar flavor, though it lacks the fresh bite of minced garlic.
sliced ginger - Substitute with ground ginger: Ground ginger can be used in place of fresh ginger, though it is more concentrated, so use less.

How to Store or Freeze This Dish
- Allow the pork belly to cool completely before storing. This helps maintain its texture and flavor.
- For short-term storage, place the char siu in an airtight container and refrigerate. It will keep well for up to 4 days.
- If you plan to store it for a longer period, wrap the pork belly tightly in plastic wrap, then place it in a freezer-safe bag or container. This prevents freezer burn and preserves the taste.
- Label the container with the date to keep track of its freshness.
- When ready to use, thaw the char siu in the refrigerator overnight. This gradual thawing helps retain its moisture.
- Reheat the pork belly by placing it in a preheated oven at 160°c (320°f) for about 10-15 minutes, or until heated through. Alternatively, you can reheat it in a microwave on medium power, ensuring it is evenly warmed.
- For a quick meal, slice the char siu thinly and add it directly to hot ramen or rice, allowing the heat from the dish to warm the meat.
- Avoid reheating the char siu multiple times as it can dry out the meat and diminish its flavor.
How to Reheat Leftovers
Oven Method:
- Preheat your oven to 150°C (300°F).
- Place the leftover Japanese Char Siu in an oven-safe dish.
- Cover the dish with aluminum foil to retain moisture.

Microwave Method:
- Place the Japanese Char Siu slices on a microwave-safe plate.
- Cover the plate with a microwave-safe lid or another plate to prevent drying out.
- Heat on medium power for 1-2 minutes, checking halfway to ensure even heating.
- If necessary, continue heating in 30-second intervals until warmed through.
Sous Vide Method:
- Preheat your sous vide machine to 60°C (140°F).
- Place the Japanese Char Siu in a vacuum-sealed bag or a resealable bag using the water displacement method.
- Submerge the bag in the water bath and heat for about 45 minutes to 1 hour.
- Remove from the bag and, if desired, sear in a hot pan for a minute on each side for added texture.
Steaming Method:
- Set up a steamer or use a steaming basket over a pot of boiling water.
- Place the Japanese Char Siu slices in the steamer.
- Cover and steam for about 5-7 minutes or until heated through.
