In a large mixing bowl, mix together ground hamburger, eggs, onion powder, bread crumbs, garlic powder, salt, pepper and barbecue sauce. Mix until well incorporated.
Weigh out hamburger patties to 100g – 175g (4 – 6 oz.) each. Press together and flatten to about 3½" in diameter or use a mold.
The patties should be about ¾" thick.
Heat a gas or charcoal grill to 450°F, or hot enough that you can only hold your hand above the grill grates forabout 1 second.
Place patties on the grill over direct heat.
Flip the burgers at least once during cooking, or as often as you wish. Do not press down on the patties at any time.
For well-done burgers, cook for 8 to 9 minutes total (160°F).
