01 - Preheat a grill to medium-high heat (about 400°F/200°C).
02 - In a small bowl, mix together melted butter, olive oil, Cajun seasoning, smoked paprika, garlic powder, onion powder, salt, and black pepper to form a spice paste.
03 - Brush each ear of corn evenly with the Cajun spice mixture, ensuring all sides are coated.
04 - Place the corn directly on the grill grates. Grill for 12–15 minutes, turning every few minutes, until the corn is tender and lightly charred on all sides.
05 - Remove from the grill and transfer to a serving platter. Garnish with chopped parsley and serve with lemon wedges for squeezing over the top.
