Raw oysters are a kitchen job, not a parking lot job. They need to stay cold and alive until the minute you open them, and that's hard to promise in a cooler on a warm afternoon, so this page serves them raw at home and grills them at the lot. Mignonette is the easy part: red wine vinegar, minced shallot and cracked pepper, stirred together and left to sit. Raw oysters also carry a real risk. They can carry Vibrio bacteria and norovirus, and the FDA and CDC advise that people with liver disease, diabetes or a weakened immune system, and pregnant people, skip raw oysters and eat them cooked. Lemon, hot sauce and alcohol don't make a raw oyster safe; only cooking does.
Homegating: Make the mignonette at least 30 minutes ahead, then shuck and serve on ice in the kitchen; two dozen take about 20 minutes to shuck once you have the rhythm. At the lot: Carry the live oysters cold, heat the grill for about 15 minutes, and grill them cup side down until the shells open, 5 to 8 minutes, plus a minute or two to curl the edges. Serve them hot with the mignonette or lemon.

Ingredients
Mignonette
- ½ cup red wine vinegar
- 2 tbsp finely minced shallot (1 small shallot)
- ½ tsp coarsely cracked black pepper
- ⅛ tsp kosher salt (Diamond Crystal; a small pinch if Morton)
Oysters
- 24 live oysters in the shell, from a certified dealer (ask to see the shellstock tag)
- Crushed ice, enough for a 2-inch bed on a rimmed platter or tray
- 2 lemons, cut into wedges
Steps
At home
- Buy the oysters the day you serve them or the day before, from a counter that keeps them on ice and can show you the shellstock tag; it lists where and when they were harvested. Bring them home in a cooler.
- Store them in the fridge, cup side down in an open bowl or tray, covered with a damp towel. Keep them at 45°F or below, and colder is better; most fridges run at 40°F or below. Don't seal them in plastic, don't set them in water, and don't bury them in loose ice that melts over them.
- Stir the vinegar, shallot, pepper and salt together in a small bowl. Let it sit at least 30 minutes, or cover and refrigerate it up to a day.
- Right before you shuck, scrub the shells under cold running water with a stiff brush. Throw out any oyster with a cracked or broken shell, and any that's open and doesn't close when you tap it.
- Spread the crushed ice on the platter and set the mignonette in the middle with a spoon.
- Shuck: fold a towel over your hand and hold the oyster cup side down, hinge toward you. Work the tip of an oyster knife into the hinge and twist until it pops. Slide the blade along the inside of the top shell to cut the muscle, lift off the top shell, then slide the blade under the oyster to free it, keeping the liquor in the cup. Flick out any bits of shell. Throw out any oyster that smells off or looks dry.
- Nestle each one into the ice as you go, add the lemon wedges and serve right away, six at a time as people eat. Keep the rest in the fridge until you shuck them. Top up the ice as it melts. Shucked oysters are out no more than 2 hours, or 1 hour above 90°F.
At the lot
- Carry the live oysters in their open mesh bag or a bowl at the bottom of the cooler, on frozen ice packs rather than loose ice, with a damp towel over them. They ride below the mignonette and lemons, stay at 45°F or below, and never sit in meltwater.
- Heat the grill to high, about 15 minutes, while you scrub the oysters with a brush and a jug of water and throw out any that are cracked or open and don't close when tapped.
- Set the oysters on the grates cup side down so the juices stay in. Close the lid and grill until the shells pop open, 5 to 8 minutes. Throw out any that stay shut.
- Lift each one off with tongs, hold it in a towel and pull off the top shell, then run a knife under the oyster to cut the muscle. If the edges haven't curled yet, set it back on the grill for a minute or two, until the edges curl and the juices bubble; it should read 145°F. Spoon on a little mignonette or squeeze on lemon and eat them hot. Cooked oysters are out no more than 2 hours, or 1 hour above 90°F.
Pack for the lot
Are raw oysters safe to eat?
They carry a real risk. Raw oysters can carry Vibrio bacteria and norovirus, and an oyster can look, smell and taste normal and still make you sick. The FDA and CDC advise that people with liver disease, diabetes, a weakened immune system, and pregnant people avoid raw oysters. Cooking is what kills the germs.
Does lemon, hot sauce or alcohol make raw oysters safe?
No. None of them kill Vibrio or norovirus. Only cooking does.
How do you store live oysters?
In the fridge, cup side down in an open bowl or tray under a damp towel, at 45°F or below, and colder is better. Don't seal them in plastic or let them sit in water or melting ice.
How do you tell if an oyster is bad?
Throw out any with a cracked shell, any that are open and don't close when you tap them, and any that smell off or look dry once shucked. When grilling, throw out any that don't open.
What is mignonette?
A sharp sauce for raw oysters: vinegar, finely minced shallot and cracked black pepper. Red wine vinegar is the common base. Make it at least 30 minutes ahead so the shallot softens.
How do you grill oysters?
Set them on a hot grill cup side down, close the lid and cook until the shells open, 5 to 8 minutes. Take off the top shell and cook a minute or two more if needed, until the edges curl and they read 145°F.
