St. Mary Parish, on the Atchafalaya

Morgan City, Louisiana: where shrimp boats and oil rigs share the river

In 1937 this river town was known as the jumbo shrimp capital of the world. Ten years later the offshore oil business started here too. It still throws one party for both every Labor Day weekend.

From Tiger Island to jumbo shrimp

The Attakapas called the river Atchafalaya, long river, and it has shaped this town from the start. U.S. surveyors first named the spot Tiger Island after reporting an unknown wild cat. Walter Brashear, a Kentucky planter and surgeon, subdivided his sugar plantation here and the settlement took his name. After the Civil War, steamship and railroad owner Charles Morgan dredged the Atchafalaya Bay Channel and made Brashear his base, and in 1876 the town was renamed Morgan City.

It became a trading town for furs, cypress timber and seafood. In 1917 its swamps stood in for the African jungle in the first Tarzan film, starring Elmo Lincoln. By 1937 the city had earned the title jumbo shrimp capital of the world. That year the community gathered for a Blessing of the Fleet, praying for safe trips and full nets, then held a fais do do at Egle's Place. That party became the Louisiana Shrimp Festival.

The working waterfront is still the point. The city describes itself as a hub for marine, seafood and energy work and as a gateway to the Atchafalaya Basin, with boats leaving before sunrise from a historic district that has been a Main Street community since 1997.

How petroleum joined the shrimp

In 1947 Kerr-McGee and its partners completed the Kermac No. 16 well at Ship Shoal Block 32, about 10 miles offshore in roughly 20 feet of water, on a platform built by Brown and Root. The American Oil and Gas Historical Society calls it the first oil well successfully completed out of sight of land, and it flowed 40 barrels an hour at first. The boom that followed tied the city's future to offshore energy, and the festival added petroleum to its name.

You can see that history up close at the International Petroleum Museum, home of Mr. Charlie, built in 1952 and put to work in 1954 as the first transportable, submersible offshore drilling rig. It drilled hundreds of wells for almost every major company in the Gulf and could house a crew of 58. The city says it is the only place the public can walk aboard an authentic offshore rig.

From the lineup

Bottles for big shrimp

Jumbo shrimp deserve better than plain cocktail sauce. Here is what we would bring.

Port A Shrimp Shack

Some Heat, 3.5 oz, $9

Named for Port Aransas, made for shrimp. A boil seasoning that works dry, with celery, coriander and a citrus lift. It goes in the breading and on top.

Knock Your Sauce Off

Some Heat, 8 fl oz, $12

Red fresno, roasted garlic, guajillo, honey and lime. The dip for a basket of fried shrimp, and good brushed on grilled ones.

Grand Isle Hook Set Sauce

Some Heat, 8 fl oz, $12

Louisiana style hot sauce with a quick kick that fades. Shake it over a pile of boiled shrimp or a bowl of gumbo.

Cook it at home

Butterflied fried jumbo shrimp

The festival food of a jumbo shrimp town. Butterflying makes big shrimp cook fast and gives the crust more to grab.

What you need

  • 2 lb large Gulf shrimp, about 16 to 20 per pound, peeled and deveined with tails on
  • 1 cup buttermilk and 1 egg
  • 1 cup flour and 1 cup fine cornmeal
  • Port A Shrimp Shack
  • Neutral oil for frying
  • Knock Your Sauce Off for dipping

How it goes

  1. Cut down the back of each shrimp almost all the way through and press it open flat.
  2. Whisk the buttermilk, egg and 1 tablespoon of Port A Shrimp Shack. Soak the shrimp in it in the fridge for 15 minutes.
  3. Mix the flour, cornmeal and 2 tablespoons of Port A Shrimp Shack in a wide bowl. Heat 2 inches of oil to 350F in a heavy pot.
  4. Lift the shrimp from the buttermilk, press them into the coating and shake off the extra.
  5. Fry a few at a time for 2 to 3 minutes, until golden and opaque in the middle. Drain on a rack and dust lightly with more Port A Shrimp Shack while hot.
  6. Serve right away with Knock Your Sauce Off for dipping.
Worth knowing. Fry in small batches so the oil stays near 350F. Crowd the pot and the temperature drops and the crust goes soft.
