Step 1

Divide the ground beef into 6 equal portions, 6-ounces each. Form into 5-inch wide patties with a deep indention in the middle. Place in a large shallow, glass baking pan.

Step 2

Mix all marinade ingredients together in a small bowl and pour over the burger patties. Turn the burgers then cover with plastic wrap. Refrigerate for at 1 to 4 hours (or longer if desired) turning at least once.

Step 3

When ready to cook, remove the burgers from the refrigerator and allow them to come to room temperature for 30 minutes before grilling.

Step 4

Clean the grill grates with a wire brush. Oil the grates with paper towels soaked with vegetable oil.

Step 5

Heat a gas grill to 325-350°F. If you don't have a thermometer, heat on high until hot, then reduce the heat to medium before adding the burgers. Using tongs, carefully oil the grilling surface again thoroughly.

Step 6

Grill the burgers until cooked through, about 7-9 minutes on each side.

Step 7

Allow the hamburgers to rest 5 to 10 minutes before serving.
