Grill grates include side walls defining the perimeter of the grill grate and flavor bars, with grease channels between them. The grease channels have continuous, closed bottoms. The flavor bars include dormers. The dormers are configured to direct drippings around the openings, to the grease channels. The dormers can have openings facing substantially towards the grease channels. The grill grates can be formed by methods such as stamping or casting. Stamping the grill grates can include providing metal with flanges and tabs to ensure sufficient material to allow the flavor bars and dormers to be formed, and the grease channels and side walls then sealed through welding. The grill grate can trap drippings in the grease channels while allowing smoke and heat to reach cooked items through the dormers in addition to heat transfer through the material of the flavor bars.
