01 - Preheat your oven to 425°F, or prepare a grill for medium-high heat.
02 - In a small bowl, mix the softened butter with Cajun seasoning, smoked paprika, garlic powder, onion powder, salt, pepper, chopped parsley, and lime juice until well combined.
03 - Place the corn cobs on a baking sheet lined with foil or parchment. Brush each ear generously with the Cajun spiced butter, ensuring all sides are coated.
04 - Roast in the preheated oven for 20-25 minutes, turning halfway through, until the corn is tender and slightly charred. Alternatively, grill the corn directly on the grates, turning every few minutes for even charring.
05 - Remove from the oven or grill. Brush with any remaining Cajun butter and sprinkle with extra parsley. Serve hot with lime wedges on the side.
