We tested all the cheese contenders twice: once on their own and then on grilled hamburgers. These are the best slices for your burgers.
Whole Foods 365 Everyday Value Kosher Cheddar $5.99 (12 ounces)
A "classic" orange cheddar, this sliced cheese melts smoothly and turns creamy on the burger. It's tangy and slightly sweet, so it can hold its own against a burger's fat and flavor. 90 calories, 4g sat fat, and 140mg sodium per slice
Boar's Head Vermont Cheddar Cheese $6.19 (8 ounces)
It might not be the color that some folks expect from cheddar, but this cheese was the tangiest and truest cheddar we tried. Even when melted, it tastes sharp and sweet with a just-right salty kick. 55 calories, 3g sat fat, and 90mg sodium per slice
