Coastal Flames: Fire-Roasted Oysters with Garlic-Parmesan Butter

How to Fire Roast Oysters on the Grill

Fire-roasting oysters directly over charcoal and hardwood embers brings bold smoky character to this coastal tradition. By cradling each shell in a salt bed and topping with a savory compound butter, you’ll achieve a perfectly charred edge and luxuriously flavored oyster liquor in every bite.

Choosing and Preparing Your Oysters

Select fresh oysters that remain tightly closed when tapped. Rinse each shell under cold water, scrubbing away any grit, and keep them chilled until you’re ready to cook. This simple cleanup preserves their briny essence and prevents premature opening on the grill.

Setting Up the Grill and Serving Vessel

Light your charcoal or hardwood and allow the coals to burn down to glowing embers. Use a cast-iron skillet or heavy pan on the grate and fill it with a generous layer of coarse rock salt. This salt bed holds each oyster level and close to the heat, preventing them from tipping or slipping through the grates.

Crafting the Compound Butter Topping

While the grill heats, prepare the butter mixture. In a bowl, combine softened unsalted butter, finely grated Parmesan, minced garlic or garlic powder, Worcestershire sauce, smoked paprika, and a few drops of hot sauce. Stir until smooth and refrigerate briefly so the mixture holds its shape when dolloped onto oysters.

Fire Roasting Process

Arrange the oysters shell side down in the salt bed. Place a small spoonful of compound butter into the center of each shell. As the grill’s radiant heat chars the shell, the butter melts into the oyster liquor, infusing it with smoky, savory richness. Close the lid or tent loosely to maintain heat while avoiding excessive steam.

Finishing Touches and Serving Suggestions

After five to ten minutes—once the shells have just begun to open and the butter is bubbling—carefully transfer the oysters to a serving platter. Garnish with chopped fresh parsley for brightness. Serve alongside a tangy cocktail sauce or a simple mayo-and-vinegar tartar sauce for an unexpected complement.

Fire-roasting oysters on a charcoal grill transforms a classic coastal roast into a dramatic centerpiece. The salt bed ensures stability, while the garlic-Parmesan butter elevates each briny oyster to a memorable smoky-rich delight. Give this method a try at your next gathering for a taste of true Southern flair.
