Preheat your Traeger grill to 350°F (175°C).
Husk the corn, removing green layers and silk threads. Rinse under cold water and pat dry.
Drizzle melted butter over each ear of corn, then season generously with salt, pepper, and optional spices.
Place corn directly on the grill grates or wrap in foil for softer results.
Grill for 20-25 minutes, turning occasionally for even cooking.
Check for doneness by piercing a kernel; it should be tender and juicy.
Serve immediately with extra melted butter or toppings as desired.
