Shape the meat mixture into four 8 oz. patties and chill for 4 hours.
Prepare the grill, rub oil on to the grate to prevent the meat from sticking. Season the burgers with kosher salt and freshly ground pepper, place on to the grill. Cook for approximately 6 minutes each side, just flipping the burgers once.
Toast the hamburger buns, place the burgers onto the bottom buns, top with bacon, romaine lettuce, and spoon caesar mayonnaise on to the lettuce, add red onion and parmesan crisp, place the bun on top. Serve with your favorite sides. Yields 4 servings.
Tips: Pre-make your hamburger patties ahead and refrigerate so the fat can set up again.
Use 80/20 choice sirloin (80% beef, 20% fat), this will make a juicy burger.
Just flip your burgers once will cooking, and never press down on the burgers, you loose to much juice.
