Blackened Shrimp
Blackened shrimp is one of the most popular seafood dishes in Key West. From shrimp shacks to upscale restaurants, it's on almost every menu.
When made with Key West Pink Shrimp, it's even better. These local shrimp are sweet, tender, and pulled from the warm waters around the Florida Keys. They have that firm snap when you bite into them.
When you start with good seafood, whether it's shrimp, fish, or shellfish, you don't need heavy sauces or flavor enhancers. This dish is no different. Key West Pinks are some of the best-tasting shrimp in the world.

Cajun Seasoning
Blackened seasoning comes from Cajun cooking in Louisiana and became famous in the 1980s thanks to New Orleans Chef Paul Prudhomme. The spice mix usually includes paprika, cayenne, garlic powder, onion powder, thyme, oregano, black pepper, and salt.

For the Blackened Seasoning
You can use homemade blackened seasoning or a tablespoon of a store-bought blend, such as Old Bay Blackened Seasoning or Chef Paul Prudhomme's Blackened Redfish Magic.
- 1 teaspoon paprika
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ⅛ teaspoon cayenne pepper or more to taste
- ⅛ teaspoon dried thyme
- ⅛ teaspoon dried oregano
- ½ teaspoon kosher salt
- ⅛ teaspoon black pepper
For the Shrimp
- 1 pound XL or jumbo shrimp thawed, peeled, and deveined
- 3 tablespoons olive oil, divided
- 3 garlic cloves crushed with the side of a knife
- 2 to 3 tablespoons unsalted butter
- 1 to 2 lemons or limes
Blackened Shrimp Recipe
- In a small bowl or screw-top jar, combine the paprika, garlic powder, onion powder, cayenne pepper, thyme, oregano, salt, and black pepper. Mix or shake until combined.
- Pat the peeled and deveined shrimp dry with paper towels.

- Place the shrimp in a bowl. Drizzle with olive oil and toss until lightly coated. Sprinkle the blackened seasoning over the shrimp and toss again until evenly coated.
- Heat a cast iron skillet over medium-high heat until hot, but not smoking. Add 1 tablespoon olive oil and swirl to coat the bottom of the pan.

- Add the shrimp and crushed garlic to the pan. Cook for 2 to 3 minutes, until the bottom darkens and the edges turn pink.
- Flip the shrimp and cook for another 1 to 2 minutes, just until cooked through. Transfer the shrimp and garlic to a clean plate.
- Lower the heat to medium-low. Add the butter to the skillet and scrape up the browned bits from the bottom of the pan. Add a squeeze of fresh lime or lemon juice.
- Return the shrimp and garlic to the skillet and toss in the butter for a few seconds. Remove from the heat and serve hot.
How to Use Blackened Shrimp for Tacos
To make blackened shrimp tacos, fold the hot shrimp into warm corn or flour tortillas with shredded cabbage, avocado, cilantro, and a squeeze of lime.
Add a spoonful of spicy mayo or cilantro lime crema for a little extra flavor.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days.
To reheat, warm the shrimp gently in a skillet over low heat with a little butter or olive oil. Heat just until warmed through. Do not overcook, or the shrimp can turn rubbery.
Leftover shrimp are great over rice, in tacos, or served cold over a salad.
What To Serve with Blackened Shrimp
Blackened shrimp pairs with simple sides that balance the smoky seasoning.
For an easy dinner, serve it over steamed white rice, coconut rice, pasta, or a bowl of creamy grits.
For a lighter meal, add a Mixed Garden Salad, Sweet Coleslaw, roasted veggies, or fresh avocado.
For an island-style plate, lean into local flavors and serve your blackened shrimp alongside yellow rice, black beans, crispy tostones, or a refreshing corn mango salsa.
You can also fold the shrimp into warm tortillas with a squeeze of lime to make incredible blackened shrimp tacos or toss them into fresh lettuce wraps for a quick lunch.
