Oyster Kaki Yaki Recipe

This oyster kaki yaki recipe features broiled oysters topped with a rich miso mayonnaise, sautéed mushrooms, and spinach. Featured on CombiNation, this dish blends Japanese flavors with Irish seafood for a savory, umami-packed appetizer that’s quick and elegant.

The Inspiration

Oyster Kaki Yaki takes inspiration from the CombiNation series, which celebrates inventive culinary fusions. As chef Craig Wong merges this recipe, the precision and umami-forward flavors of Japanese cuisine with the hearty, comforting elements of Irish culinary tradition. In Japan, oysters are often prepared with miso or creamy sauces and broiled to develop a caramelized finish, while in Ireland, seafood is celebrated for its freshness and pairing with buttery, creamy textures.

The combination in Oyster Kaki-Yaki highlights how these two culinary worlds intersect. Japanese ingredients such as enoki mushrooms, mirin, and miso bring depth and savoriness, while Irish influence is evident in the richness of the butter and mayo base. This fusion elevates simple oysters into a gourmet appetizer that balances umami, spice, and creaminess.

Ingredients

• 6 oysters
• 1 tablespoon (15 ml) butter
• ¼ yellow onion, small dice
• ½ cup (120 ml) enoki mushrooms, cut 1 inch (2.5 cm) from the top
• 2 tablespoons (30 ml) finely chopped blanched spinach
• 4 tablespoons (60 ml) Japanese Mayo
• 1 teaspoons (5 ml) red miso
• 1 tablespoon (15 ml) Mirin
• 1 tablespoon (15 ml) sweet soy
• 1/8 teaspoon (.75 ml) cayenne pepper
• Fish roe, to garnish
• Rock salt, as needed (for leveling oysters)

Method

• Heat a broiler to high heat. Prepare a baking pan with rock salt to level the oysters after shucking and for roasting.
• Shuck the oysters and loosen the meat in the shell.  Drain the liquor and reserve for another use. Arrange in the prepared pan to keep level.
• Heat butter in a small sauté pan over medium heat. Sweat onions, enoki mushroom, and spinach until soft, then set aside to cool.
• In a mixing bowl, combine mayonnaise, miso paste, mirin, and sweet soy.
• Add the onion/mushroom/spinach mixture over the oysters.
• Spread the mayonnaise mixture on the top of the veggies, sprinkle cayenne pepper and return to the pan.
• Broil until golden brown, 2 minutes. Garnish with fish roe and serve immediately.
