For the Spicy Miso Butter:
  • 4 tablespoons unsalted butter, softened
  • 2 tablespoons miso paste (white or red)
  • 1 tablespoon sriracha or other hot sauce
  • 1 teaspoon soy sauce
  • 1 teaspoon lemon juice
  • 1 garlic clove, minced
  • 1 tablespoon finely chopped green onions (optional)
  • 1 tablespoon finely chopped cilantro (optional)
For the Oysters:
  • 12 fresh oysters, scrubbed clean and kept in their shells
  • Lemon wedges, for serving


1. Prepare the Spicy Miso Butter:

  • In a small bowl, combine the softened butter, miso paste, sriracha, soy sauce, lemon juice, and minced garlic.
  • Mix thoroughly until all ingredients are well combined and the butter is smooth.
  • If using, fold in the finely chopped green onions and cilantro for added freshness and flavor.
  • Cover the spicy miso butter and refrigerate until ready to use.

2. Preheat the Grill:

  • Preheat your grill to medium-high heat, about 400°F (200°C).

3. Prepare the Oysters:

  • Carefully shuck the oysters, keeping them on the half shell and retaining as much of the oyster liquor (juice) as possible. If you are not comfortable shucking oysters, you can ask your fishmonger to do it for you.
  • Place the shucked oysters on a tray, making sure they are stable and the oyster liquor does not spill.

4. Grill the Oysters:

  • Place the oysters directly on the preheated grill, making sure they are level to prevent the oyster liquor from spilling.
  • Grill the oysters for about 3-5 minutes, or until the edges start to curl and the oysters are just cooked through.

5. Add the Spicy Miso Butter:

  • While the oysters are grilling, spoon a small dollop of the prepared spicy miso butter onto each oyster.
  • Continue grilling for an additional 1-2 minutes, or until the butter has melted and the oysters are infused with the spicy miso flavor.

6. Serve and Enjoy:

  • Carefully remove the grilled oysters from the grill using tongs.
  • Arrange the oysters on a serving platter, garnishing with lemon wedges.
  • Serve immediately, enjoying the smoky, savory, and slightly spicy flavors of the grilled oysters with spicy miso butter.

Serving Suggestions:

  • Appetizer: Serve as an elegant appetizer at dinner parties or special occasions.
  • Seafood Feast: Include as part of a seafood feast with grilled shrimp, crab legs, and lobster.
  • Paired with Wine: Pair with a crisp white wine or sparkling wine to complement the rich flavors of the oysters.

Cooking Tips:

  • Shucking Oysters: Use a proper oyster knife and protective glove to safely shuck oysters, or have them shucked by your fishmonger.
  • Grill Stability: Ensure the oysters are stable on the grill to prevent tipping and spilling of the oyster liquor.
