Grilled burgers are always a hit for dinner at our house. Living on a cattle ranch, we generally have a freezer full of ground beef and hamburgers are definitely on the menu at least once a week.

These epic burgers are part of a fantastic month-long event hosted by Girl Carnivore, but opinions are always my own!

Weber Grill with flaming coals

  • Prepare a grill fire to about 300. We used lump charcoal with a bit of hickory for smoke flavor in our Weber Kettle Grill
  • Rake the coals to the edges as the fire started to die down to cook the burgers over indirect heat.
