Grill or Smoker: Preheat to 250 degrees F, using indirect heat and your choice of wood chips for a smoky flavor. Oven: Preheat to 375 degrees F.
Brown your hamburger meat in a large pan on the stovetop, drain grease and return to the pan. Then add in taco seasoning and a splash of water until the meat is evenly coated.
Lightly spray a 9X13 disposable foil pan with cooking spray. Place all the ingredients in the pan and combine, stirring well to mix everything together evenly.
Grill or Smoker: Place the pan on the grill or smoker, away from direct flame, and cook for 1-2 hours, stirring occasionally, until the cheese is fully melted and the dip is hot and bubbly.
Oven: Place the pan into the oven and bake for 15 minutes or until melted, stirring halfway through.
Serve your smoked queso with your favorite dippers and enjoy the rave reviews from your guests!
