Grilled Gulf Oysters
Straight onto the grate on the half shell. Butter, blend, and off the moment the edges curl. Any longer and you are eating something that used to be an oyster. This one comes together fast, which is exactly the point of a dish that's really just an excuse to stand next to a hot grill with a cold drink while the tide comes in.
We've made these over charcoal, over gas and over a straight-up open fire on the beach, and honestly the fire version might be the best of the three - something about the smoke off real wood coals that a gas burner can't fake. If you're working with charcoal, let the coals burn down until they're covered in gray ash with an orange glow underneath; that's when the heat is steady instead of spiking. Open fire is more art than science: build a good bed of coals off to one side, rake them flat, and set your grate a few inches above.
Equipment
- Charcoal or gas grill
- Oyster knife
- Rock salt or foil for the tray
- Grill gloves
Temperatures at a glance
| Charcoal grill | Hot direct heat, coals glowing orange-white, grate about 450-500F |
| Gas grill | High, lid closed 10 minutes to preheat, grate around 475F |
| Open fire | A hot coal bed raked flat, no flame - oysters go straight on a grate over the coals |
Ingredients
- 2 dozen Gulf oysters, shucked on the half shell
- 1 stick unsalted butter, melted
- 2 tbsp Gulf Coast Blackening
- 2 cloves garlic, minced (optional, for a garlic butter version)
- 1 lemon, cut into wedges
- Rock salt or foil, for the tray
- Grilled bread, to serve
- Hot sauce, for the table
Method
- Get the grill hot, lid down for ten minutes, before anything goes near it. This is not a low and slow situation - you want the grate at 450F or better, hot enough that a drop of water skitters and disappears in under a second.
- If you're working with charcoal, load a full chimney and let it burn until every coal is covered in gray ash. Dump it into one side of the grill for a hot direct zone. On an open fire, build your coal bed early - you want it burned down to glowing embers, not still flaming, by the time the oysters go on.
- Bed the oysters in a tray of rock salt or crumpled foil so they sit level and none of the liquor spills. This part matters more than it looks like it would - a tilted oyster loses its butter into the coals instead of onto the meat.
- Stir the blend into the melted butter (add the garlic here if you're using it) and spoon a little over each oyster, right on the meat.
- Set the tray on the grate over direct heat. Close the lid and give it 4 to 5 minutes - you are watching for the edges to curl and the butter to bubble hard. On an open fire without a lid, tent a sheet of foil loosely over the tray to trap some heat.
- Pull them the moment they curl. A few extra seconds turns a plump oyster into a rubber one - this is a dish where impatience is the wrong instinct but so is walking away.
- Squeeze lemon over the tray and serve straight off the grill with grilled bread for the butter left in the shells and hot sauce on the side for anyone who wants more.
Tips from the kitchen
- Buy oysters the day you're cooking them if you can. Shucked oysters sitting around lose liquor, and liquor is half the flavor here.
- If you don't have an oyster knife, most fish counters will shuck them for you on the spot - worth asking.
- Leftover blended butter freezes fine. Make a double batch and keep it on hand for the next time a cooler of oysters shows up.
Any longer on the heat and you're eating something that used to be an oyster. Watch the edges, not the clock.
