Step 1: Prepare the Shrimp

1. Rinse the shrimp under cold water and pat them dry with paper towels. Removing excess moisture ensures they will sear properly and develop a crispy crust.
2. Place the shrimp in a mixing bowl and drizzle with olive oil. Toss to coat evenly.

Step 2: Make the Blackening Seasoning

1. In a small bowl, combine smoked paprika, garlic powder, onion powder, dried oregano, dried thyme, cayenne pepper, black pepper, and salt. Mix thoroughly to create the blackening seasoning.
2. Sprinkle the seasoning evenly over the shrimp, tossing to ensure each piece is fully coated.

Step 3: Heat the Pan

1. Heat a large cast-iron skillet or heavy-bottomed pan over medium-high heat. Allow the pan to get very hot—this is key to achieving the signature blackened crust.
2. Add a tablespoon of olive oil or butter to the skillet and swirl to coat.

Step 4: Cook the Shrimp

1. Place the seasoned shrimp in a single layer in the hot skillet, ensuring they’re not overcrowded. You may need to cook them in batches if necessary.
2. Cook the shrimp for 2-3 minutes on the first side, until the underside is darkened and crispy.
3. Flip the shrimp and cook for another 1-2 minutes on the second side, until they are opaque and fully cooked. Shrimp cook quickly, so be careful not to overcook them.
4. Remove the shrimp from the pan and transfer them to a plate.

Step 5: Garnish and Serve

1. Garnish the blackened shrimp with freshly chopped parsley and serve with lemon wedges for a burst of brightness.
2. Serve immediately, while the shrimp are hot and juicy.
