Pat 1 pound large shrimp, peeled and deveined dry with paper towels and place in a large bowl.
Drizzle with 1½ Tablespoon olive oil and toss to coat evenly.
In a small bowl, mix 1 teaspoon smoked paprika, 1 teaspoon garlic powder, 1 teaspoon onion powder, ½ teaspoon dried thyme, ½ teaspoon dried oregano, ½ teaspoon salt, ½ teaspoon black pepper, and ¼ teaspoon cayenne pepper.
Sprinkle the seasoning over the shrimp and toss until fully coated.
Heat a large skillet (preferably cast iron) over medium-high heat until hot.
Add shrimp in a single layer and cook for 2–3 minutes per side, until opaque and slightly charred.
Add 1 Tablespoon butter to the skillet during the last minute of cooking and toss the shrimp to coat.
Remove from heat and serve immediately with lemon wedges and fresh parsley.
