This Japanese roast pork recipe brings together the rich flavors of soy sauce, mirin, and aromatic spices to create a succulent and tender dish. Perfect for a family dinner or special occasion, this roast pork is sure to impress with its savory and slightly sweet taste.

Ingredients For Japanese Roast Pork Recipe
Boneless pork shoulder: A tender cut of meat that becomes juicy and flavorful when roasted.
Soy sauce: Adds a rich, umami flavor to the marinade.
Mirin: A sweet Japanese rice wine that enhances the overall taste.
Sugar: Balances the saltiness of the soy sauce and adds a hint of sweetness.
Salt: Enhances the natural flavors of the pork.
Freshly ground black pepper: Adds a mild heat and depth of flavor.
Minced garlic: Infuses the pork with a robust, aromatic flavor.
Grated ginger: Adds a fresh, slightly spicy note to the marinade.
Technique Tip for This Recipe
When preparing the pork shoulder, ensure you marinate it for at least an hour before roasting. This allows the flavors from the soy sauce, mirin, garlic, and ginger to penetrate the meat more deeply, resulting in a more flavorful and tender roast. Additionally, using a meat thermometer to check the internal temperature ensures that the pork is cooked perfectly without drying out.

Alternative Ingredients
boneless pork shoulder - Substitute with boneless pork loin: Pork loin is leaner but can still provide a tender texture when cooked properly.
soy sauce - Substitute with tamari: Tamari is a gluten-free alternative that offers a similar umami flavor.
mirin - Substitute with dry sherry: Dry sherry can mimic the sweetness and depth of flavor found in mirin.
sugar - Substitute with honey: Honey provides a natural sweetness and can add a slight floral note.
salt - Substitute with kosher salt: Kosher salt has a similar flavor but is less dense, so you may need to adjust the quantity.
freshly ground black pepper - Substitute with white pepper: White pepper has a milder flavor and can blend more seamlessly into the dish.
minced garlic - Substitute with garlic powder: Garlic powder can provide a similar flavor, though it lacks the fresh bite of minced garlic.
grated ginger - Substitute with ground ginger: Ground ginger can be used in a pinch, though it has a more concentrated flavor.
