Blackened Shrimp with Butter Sauce is a one-pan dish, so easy to make, and I promise you'll be eating these right out of the pan. I use fresh wild Key West shrimp, a homemade blackening seasoning blend, some lemons, unsalted butter, and a cast-iron frying pan.

We eat a lot of shrimp in Florida. The shrimp are harvested right off the coast of Key West. They're wild-caught, sweet, plump, and with very little effort, I make delicious meals like this in minutes.

A Great Shrimp Dish Starts with Wild Shrimp
Most shrimp sold commercially are from farms where an artificial environment is created. Key West shrimp are harvested right off the coast of the Florida Keys. The shrimp live at the bottom of the sea and dine on sea animals, algae, and other marine food. They're really fresh!
What is Blackening Seasoning?
Blackening is a cooking style that has its roots in Cajun cuisine. The spices used to coat the shrimp are bold and include cayenne pepper, chili powder, and sweet paprika. I use a small amount of onion powder for sweetness. Blackened shrimp is a popular dish at many southern restaurants.

How To Peel and Devein The Shrimp
Before making blackened shrimp, decide whether you want to keep the tails on, or not. The shrimp look better on a dinner plate with their tails. However, if you're making shrimp tacos, remove them. If you have kids, pay close attention to getting all the shells off, including the tail, to avoid choking hazards.
Shrimp are easy to peel. You can do this with a paring knife or a pair of scissors.
- Rinse shrimp and pat dry
- Pull off the legs
- Peel back the shell
- If you want to keep the tail on, when you peel back the shell, hold on the top of the tail to keep it intact.
- Cut a shallow incision in the back of each shrimp and lift out the dark vein with the tip of the knife. It is really easy once you get the hang of it.
The vein of the shrimp is the shrimp's digestive tract. Some shrimp have a dark vein and in others, it's hardly noticeable.
