01 - Preheat grill to medium-high heat (or preheat oven to 430°F if roasting).
02 - In a small bowl, whisk together melted butter, smoked paprika, garlic powder, onion powder, thyme, oregano, cayenne, black pepper, and salt until smooth.
03 - Brush each ear of corn generously with the Cajun spice mixture, ensuring all sides are evenly coated.
04 - Place corn directly on grill grates (or on a parchment-lined baking sheet if roasting).
05 - Grill corn, turning every 3–4 minutes, until nicely charred and tender, approximately 12–15 minutes total.
06 - Remove from heat and let cool slightly. Garnish with fresh parsley if desired and serve with lemon wedges for squeezing over the top.
