Start by preheating your grill to medium-high heat, ensuring it's ready for a perfect char on the corn.
In a medium mixing bowl, combine the softened butter, Cajun seasoning, garlic powder, smoked paprika, cayenne pepper, and a pinch of salt. Use a fork or spatula to mix until well blended, creating a creamy, flavorful Cajun butter.
Take each ear of corn and generously apply the Cajun butter all over, making sure to coat every side for maximum flavor.
Wrap each buttered corn cob in aluminum foil, sealing tightly so no steam escapes during grilling. This will help keep the corn juicy.
Place the two wrapped corn cobs directly onto the grill grates and allow them to cook for 15-20 minutes. Be sure to turn them every few minutes for even cooking; look for tender kernels as an indicator of doneness.
Carefully remove the corn packets from the grill using tongs and let them cool for a couple of minutes before unwrapping—exercise caution as the hot steam can escape when you peel back the foil.
If desired, brush any remaining Cajun butter left on the foil onto your corn for an extra rich flavor punch.
To serve, garnish the corn with freshly chopped parsley and provide lime wedges on the side for that sizzling zest to elevate your dish!
Notes
For extra flavor, brush remaining Cajun butter on the corn before serving.
