While infrared is great for searing steaks, everyone should know how to cook a great hamburger. Since infrared grills cook a little differently than regular gas or charcoal grills.
First, preheat your infrared grill by setting it on the highest possible setting.
Make your best hamburgers, the same way you normally would. I like mine with onion soup mix and a dash of tabasco. Everyone has their own style, but I recommend making an indentation in the middle of the burgers because otherwise they could turn out round rather than flat.
Once you're ready, turn down the heat on the grill to medium. Lightly pray olive oil on the burgers to prevent them from sticking and to add a little bit of extra flavor.
Pay attention, because of the higher temperature, the burgers will sear and cook quickly. After about a minute, flip the burgers. 30 seconds or so later it should be mostly cooked on both sides. Give it another flip and 30 seconds later the last flip. This way you can get nice diamond grill marks on both sides.
If you want to add cheese or other toppings, do it on the last flip, but turn off the grill and close the lid. The radiant heat will be enough to melt the cheese, but don't leave them in too long or the burgers will overcook.
Infrared is great for burgers because they will cook quickly without drying out, and on newer models, the drippings will be evaporated instantly, bathing the burgers in their own smoky essence, without leaving a mess on the burners.
