01 - Preheat your grill to medium-high heat (about 400°F/200°C).
02 - In a small bowl, mix together the softened butter, smoked paprika, garlic powder, onion powder, oregano, thyme, cayenne, salt, and black pepper until well combined to make the Cajun butter.
03 - Brush each ear of corn generously with half of the Cajun butter mixture.
04 - Place corn directly on the grill grates. Grill, turning every 2–3 minutes, until the corn is nicely charred and tender, about 12–15 minutes total.
05 - Remove corn from the grill and immediately brush with the remaining Cajun butter.
06 - Sprinkle with chopped parsley and serve with lime wedges on the side.
