Place the shrimp in a large bowl and add 1 tablespoon of olive oil along with the blackened seasoning. Toss the shrimp thoroughly so each piece is coated with the flavorful spice blend.
Add the remaining tablespoon of olive oil to a skillet over medium heat. Let it warm for about a minute so the shrimp cooks evenly without sticking.
Add the seasoned shrimp to the skillet. Cook for about 2 minutes per side until the shrimp turns pink and opaque and the seasoning forms a fragrant, dark crust. Remove from heat immediately to prevent overcooking.
Transfer the shrimp to a serving dish and garnish with fresh herbs or a squeeze of lemon. Serve hot for the best flavor and texture.
