Charbroiled oysters in New Orleans trace back to one kitchen: Drago's in Metairie, where Tommy Cvitanovich started grilling oysters on the half shell with butter, garlic, and cheese in 1993. Three decades later, you'll see them on menus all over town, sizzling on a grill and filling the room with smoke and garlic.
They also answer a question we hear every summer behind the counter: can you eat oysters in a month without an R? We'll get there. First, the butter.
How Drago's Invented Charbroiled Oysters
Drago's was opened by Drago and Klara Cvitanovich and became a Metairie institution. According to Explore Louisiana, the state tourism office, their son Tommy took the technique and toppings from a redfish dish and tried them on oysters in 1993. It became the restaurant's signature.
The method is simple and hard to stop eating. Shuck the oyster, leave it in the half shell, spoon over butter whipped with garlic and herbs, dust with Pecorino Romano, and put the whole thing over high flame. The butter boils in the shell. The edges of the oyster curl. The cheese browns. You eat it with French bread, and the bread is for the butter left in the shell, which is honestly the best part.
Most places serve them by the half dozen or dozen. A dozen for the table disappears in about four minutes.
Charbroiled Oysters in New Orleans Today
Charbroiled oysters went from one restaurant's specialty to something close to a city standard. Plenty of oyster bars and seafood houses around town have their own version, some with extra cheese, some with a little heat. Drago's itself has expanded well beyond Metairie, including a Baton Rouge location at Perkins Rowe announced in 2025.
If you want to do it at home, you need a hot grill, a lot of butter, and somebody else to shuck. We make The Four Step Shuck Apron for whoever ends up stuck with that job.
The R-Month Rule: Is It Still True?
You've heard it: only eat oysters in months with an R in them, September through April. Skip May, June, July, and August.
The short answer is that the rule is mostly about raw oysters, and it's more of a rough guide than a law. Here's what's actually going on.
The concern is Vibrio, a bacteria that lives naturally in warm, brackish water. The Louisiana Department of Health says Vibrio is found in higher numbers from May to October, when coastal water is warmer. That lines up roughly with the R-month rule, though October has an R and is still on the warm list.
But Vibrio "can be present year-round," as LSU AgCenter seafood specialist Evelyn Watts put it in a 2025 article. So the calendar is not a guarantee in either direction.
What has changed is how oysters are handled. According to LSU AgCenter, Louisiana uses cold-chain and traceability rules, and the color of the tag on each sack shows whether harvest refrigeration times were met. White-tagged oysters can be sold for eating raw. Green-tagged oysters have to go to processing first.
Why Charbroiled Oysters Are the Summer Answer
Here's the part that ties this together. LSU AgCenter states that thoroughly cooking oysters eliminates the Vibrio risk.
So if you're in town in July and you want oysters, charbroiled ones are the easy call. Same for fried oysters on a po-boy. Our local's guide to po-boys has thoughts on that.
Raw oysters in summer are a personal decision, and plenty of healthy locals eat them year-round. But LDH lists people who should be especially careful with raw or undercooked seafood, including anyone with liver disease, diabetes, cancer, HIV, or a weakened immune system, people on medicine that lowers stomach acid, and pregnant people. Restaurants in Louisiana post advisories about raw shellfish for a reason.
For context on the numbers: as of Oct. 14, 2026, LDH reported 19 Vibrio vulnificus cases in Louisiana this year, with seven deaths. Seventeen of those cases came from wound or seawater exposure, not from eating. So the bigger everyday risk for most people is a cut on your leg at the camp, not a dozen on the half shell. LDH says to stay out of brackish water with an open wound, or cover it with a waterproof bandage.
None of this is a reason to panic. Know who you're feeding, and order accordingly.
Louisiana Oysters and the Coast
Louisiana leads the country in oyster production and supplies more than 75 percent of Gulf oyster landings, according to LSU AgCenter. Oysters are the state's third most valuable seafood harvest, behind shrimp and crab.
That supply depends on the marsh and the estuaries along the coast, which are washing away. We've written about it in Make Wetlands Not War, and the design came out of the same worry. You can put it on your truck with the Make Wetlands Not War Bumper Sticker. The oysters on your plate at a charbroil place are coming out of that same water.
For a smaller reminder, the Oyster Enamel Pin goes on a hat or a jacket and starts conversations at bars. And if you'd rather eat them raw, we have a whole local's guide to the half shell.
Charbroiled Oysters New Orleans: FAQ
Who invented charbroiled oysters?
Charbroiled oysters were created at Drago's restaurant in Metairie in 1993 by Tommy Cvitanovich, son of founders Drago and Klara Cvitanovich. He adapted toppings from a redfish dish to oysters on the half shell.
Is it safe to eat oysters in the summer in New Orleans?
Cooked oysters, including charbroiled and fried, are the safe choice year-round, because thorough cooking eliminates Vibrio risk. Raw oysters carry more risk from May to October, especially for people with liver disease, diabetes, or weakened immune systems.
What is the R-month rule for oysters?
The old rule says to eat oysters only in months with an R, September through April. It roughly matches the warm-water months when Vibrio levels are higher, but Louisiana's refrigeration and tagging rules matter more today, and cooking removes the concern.
