Preheat the oven to 350 degrees F (175 degrees C).
Place corn, in husks, directly on the oven rack.
Roast in the preheated oven until tender and cooked through, 40 to 45 minutes.
Peel down husks and rub each ear of corn with 1 tablespoon butter. Sprinkle each with Cotija cheese, cilantro, Taco Seasoning, and lime juice. Serve.
