Ingredients

Scale

Oysters

  • 24 fresh oysters

Miso Butter Sauce

  • 6 tablespoons butter, softened
  • 2 tablespoons white miso
  • 1 to 2 tablespoons Sriracha hot sauce (adjust to taste)
  • 1 tablespoon lime juice
  • 1/8 teaspoon ground black pepper

Garnish

  • 1 bunch scallions, thinly sliced on a slight diagonal
  • Togarashi seasoning, to taste
  • Lime wedges, for serving

Instructions

  1. Prepare the Miso Butter: In a small bowl, combine the softened butter, white miso, Sriracha hot sauce, and lime juice. Mix thoroughly until smooth and well blended. Add a few grinds of black pepper and then refrigerate the mixture until ready to use.
  2. Clean the Oysters: Check that the oysters are alive by ensuring their shells are tightly closed; discard any oysters that are open. Scrub the oyster shells thoroughly under running water with a stiff brush to remove any dirt or debris, then rinse well. Refrigerate the oysters until ready for grilling.
  3. Shuck the Oysters: When ready to cook, use an oyster knife to pry open the oyster shells. Discard the top shell and carefully loosen the oyster meat from the bottom shell, leaving it nestled in the shell for cooking.
  4. Preheat the Grill: Build a hot charcoal fire for direct grilling. Arrange the oysters on the half shell directly over the charcoal with the deeper shell facing upward to hold juices.
  5. Grill Oysters Initially: Cook the oysters over direct heat for approximately 3 minutes, allowing them to start cooking through and open slightly.
  6. Add Miso Butter Topping: Spoon about 1/2 teaspoon of the chilled miso butter onto each oyster, adjusting quantity for oyster size as needed.
  7. Finish Grilling: Return the oysters to the grill and cook for an additional 3 minutes, letting the miso butter melt and infuse the oysters with rich, spicy flavor. Alternatively, you may cook them in a preheated 450°F oven following the same timing.
  8. Garnish and Serve: Remove oysters from the grill, scatter thinly sliced scallions over the top, and sprinkle with togarashi seasoning. Serve immediately in the half shells with fresh lime wedges on the side for squeezing.

Notes

  • Ensure oysters are fresh and alive before cooking to avoid foodborne illness.
  • If you don’t have a charcoal grill, you can use a preheated oven at 450°F for approximately 6 minutes total, adding the miso butter halfway through cooking.
  • Adjust the amount of Sriracha to your preferred spice level.
  • Use a proper oyster knife and wear a protective glove or towel to safely shuck oysters.
  • Togarashi adds a lovely Japanese chili flavor, but you can substitute with a pinch of cayenne or chili flakes if unavailable.
